Rails Note #13: RubyonRails + Oracle on Linux (i386 / x64)

rupert — Thu, 11 Dec 2008 00:53:48 +0000

In summary, install Oracle Instant Client and try to run sqlplus. If sqlplus connects to the oracle sid then go ahead and install the rails adapters for oracle. What is important to note here, is to install the oracle-instantclient for the architecture of your machine.. I have tested this on Debian Lenny (i386) and CentOS5 (x64)

1. Download from http://www.oracle.com/technology/software/tech/oci/instantclient/

a. oracle-instantclient-basic-10.2.0.4-1.i386
b. oracle-instantclient-devel-10.2.0.4-1.i386
c. oracle-instantclient-sqlplus-10.2.0.4-1.i386

2. Unzip everything to /opt/oracle/instantclient . You should have something like the ff:

[root@csapp1 instantclient]# ls -la
total 102704
drwxr-xr-x 3 root root     4096 Dec 10 21:54 .
drwxr-xr-x 3 root root     4096 Dec 10 22:03 ..
-rw-r--r-- 1 root root      228 Dec 10 21:52 BASIC_README
-r--r--r-- 1 root root  1609607 Dec 10 21:52 classes12.jar
-rwxr-xr-x 1 root root    67542 Dec 10 21:52 genezi
-r--r--r-- 1 root root     1525 Dec 10 21:52 glogin.sql
lrwxrwxrwx 1 root root       17 Dec 10 21:54 libclntsh.so -> libclntsh.so.10.1
-rwxr-xr-x 1 root root 21038613 Dec 10 21:52 libclntsh.so.10.1
-r-xr-xr-x 1 root root  3796601 Dec 10 21:52 libnnz10.so

-r-xr-xr-x 1 root root  1435561 Dec 10 21:52 libsqlplusic.so
-r-xr-xr-x 1 root root   997409 Dec 10 21:52 libsqlplus.so
-r--r--r-- 1 root root  1555682 Dec 10 21:52 ojdbc14.jar
drwxr-xr-x 4 root root     4096 Dec 10 21:52 sdk
-r-xr-xr-x 1 root root     7773 Dec 10 21:52 sqlplus
-rw-r--r-- 1 root root      232 Dec 10 21:52 SQLPLUS_README
-rw-r--r-- 1 root root      516 Dec 10 21:53 tnsnames.ora
[root@csapp1 instantclient]#

3. Make a symbolic link for libclntsh.so.10.1 as shown above.

4. Create the Oracle Environment variables

export ORACLE_HOME=/opt/oracle/instantclient
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME

5. At this point, you should have oracle-instantclient properly installed. You can test by running sqlplus.

[root@csapp1 instantclient]# sqlplus
 
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 11 11:47:40 2008
 
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.

NOTE: Sometimes you will get a SEGMENTATION FAULT. If so, try to open a new shell with the environment variables loaded and do an sqlplus in a directory which is not /opt/oracle/instantclient.

6. Install the oracle adapter for rails

7. gem install ruby-oci8

8. gem install oracle_enhanced-adapter –source=”http://gems.rubyonrails.org/”

activerecord-oracle-adapter (1.0.0.9250)
activerecord-oracle_enhanced-adapter (1.1.8)

NOTE: Try to look for the latest gems, the source above is at the time of this writing so it might change.

9. Test using irb

[root@csapp1 instantclient]# irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'oci8'
=> true
irb(main):003:0>

Installing Oracle11g x64 on CentOS5

rupert — Sat, 26 Jul 2008 04:36:25 +0000

FOR EDITING.. This is just a couple of notes from my Oracle testing a few weeks back that I forgot to post..

A. Installing

1. Check for rpm packages:

rpm -q binutils compat-db control-center gcc gcc-c++ glibc glibc-common gnome-libs libstdc++ libstdc++-devel make pdksh sysstat xscreensaver libaio openmotif21 elfutils-libelf libaio-devel libgcc

NOTE: For 10g, you need libXp.so.6 installed. It seems the oracle installer is messed up with some i386 modules pointing to x86? Anyway, I was able to resolve the problem by installing the libXp.i386.rpm version.

2. install the necessary rpm packages:

rpm -ivh compat-db-4.2.52-5.1.x86_64.rpm 
rpm -ivh libgnome-2.16.0-6.el5.x86_64.rpm 
rpm -ivh sysstat-7.0.0-3.el5.x86_64.rpm 
rpm -ivh libaio-devel-0.3.106-3.2.x86_64.rpm 
rpm -ivh lm_sensors-2.10.0-3.1.x86_64.rpm
rpm -ivh beecrypt-devel-4.1.2-10.1.1.x86_64.rpm elfutils-devel-0.125-3.el5.x86_64.rpm net-snmp-devel-5.3.1-19.el5.x86_64.rpm elfutils-devel-static-0.125-3.el5.x86_64.rpm net-snmp-5.3.1-19.el5.x86_64.rpm net-snmp-libs-5.3.1-19.el5.x86_64.rpm

3. vim /etc/profile

ORACLE_BASE=/opt/oracle/product
ORACLE_SID=csdbora
ORACLE_HOME=/opt/oracle/product/11.1.0/db_1
 
export ORACLE_BASE ORACLE_SID ORACLE_HOME
 
PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

4. Create oracle Account

groupadd oinstall
groupadd dba
useradd -m -g oinstall -G dba oracle
id oracle

uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

5. Run modify_kernel.sh

cat >> /etc/sysctl.conf << EOF
kernel.shmall = 2097152
kernel.shmmax = 1073741824 
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1025 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 262144
EOF

6. vim /etc/sysctl.conf and comment kernel.shmall and kernel.shmmax because if
you don’t then we will have double results

7. /sbin/sysctl -p

8. Create Directories:

mkdir -p /u01
mkdir -p /opt/oracle
mkdir -p /opt/oracle/product
chown -R oracle:oinstall /u01
chown -R oracle:oinstall /opt/oracle
chmod -R 755 /u01
chmod -R 755 /opt/oracle
chmod -R 755 /opt/oracle/product

9. Run sh -v modify_shelllimits.sh

10. Add the ff lines in /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so

11. cp -rf /home/installers/linux.x64_11gR1_database.zip /opt/oracle

12. chown oracle:oinstall /opt/oracle/linux.x64_11gR1_database.zip

13. Clost all terminals and logout as root from desktop.

14. Login as oracle

15. Follow tutorial until installing oracle
Installing Oracle 11g on CentOS under VMWare on a Macbook.doc

To extract: cpio -idmv < 10201_database_linux_x86_64.cpio

vim /etc/redhat-release
Redhat 4

16. Run the 2 scripts after the dialog:

[root@cs5ora11g db1]# sh root.sh
Running Oracle 11g root.sh script…

The following environment variables are set as:
ORACLE_OWNER= oracle

17. Open your firewall to 1158

18. Go to https://192.168.1.155:1158/em

- Login as SYSMAN:[password] (nickname+wife)

19. Install Oracle Instant Client for your distro [MacOS]

http://www.oracle.com/technology/software/tech/oci/instantclient/index.html

a. Add exports to runsqlplus.sh
b. copy tnsnames.ora from centos to mac
c. add in firewall: 1521
d. sh runsqlplus.sh

20. do sqlplus
Enter user-name: SYSMAN@cybersof

Installing Mapserver on Debian (reprise)

rupert — Fri, 28 Mar 2008 11:31:43 +0000

As noted from my previous blog post regarding Mapserver on Debian, you don’t get AGG with Mapserver when installing directly from Debian packages. Thus, it would be better to install Mapserver by source. However, debian still helps because it would install all the necessary libraries needed for compiling mapserver.

./configure \
--with-agg \
--with-jpeg \
--with-gd \
--with-freetype \
--with-png \
--with-ogr \
--with-proj \
--with-gdal \
--with-httpd=/usr/sbin/apache2 \
--with-tiff \
--with-wfs \
--with-wcs \
--with-threads \
--with-wmsclient \
--with-wfsclient \
--with-geos \
--with-postgis \
--enable-debug

When I started installing yesterday, I did not know which packages/libraries are installed in my box. I dove off immediately by running my configure.sh above and received an error: Could not find gd.h or libgd.a/libgd.so in /usr/local..

The best way to figure out if you’re ready is reading thru the configure output.

Installing Firefox on Linux (Debian)

rupert — Wed, 05 Mar 2008 00:17:10 +0000

I read somewhere that Firefox was renamed to Iceweasel on Debian. Thus, I can’t install the Google Toolbar for it. So here are the steps for installing Firefox manually in a linux system.

1. Download the source from Mozilla’s site

2. Unpack the source. tar -zxvf firefox-2.0.0.12.tar.gz

3. Create a shell script pointing to the binary of the source.

#!/bin/sh
cd /home/rupert/firefox
./firefox &amp;

4. Grant execute rights to the script.

5. Right click on the top-panel and click “Add To Panel”

6. Choose “Custom Application Launcher” and specify the ff:

Name: "Firefox"
Command: /home/rupert/firefox.sh
Comment: Mozilla Firefox Browser.

7. Click on the Left Button to specify an icon to the launcher.

8. Click on Browse and navigate to /home/rupert/firefox/icons

9. Let’s install Google Toolbar.

10. Restart Firefox.

If you want to install the Adobe Flash Plugin, then download the player (install_flash_player_9_linux.tar.gz) from Adobe.

# tar -zxvf install_flash_player_9_linux.tar.gz
# cd /home/rupert/install_flash_player_9_linux.tar.gz
# ./flashplayer-installer

SquirrelMail SMTP Authentication

rupert — Fri, 04 Jan 2008 13:16:44 +0000

Just a quick note to myself… A co-worker just notified me that they cannot send email using the web interface–squirrelmail.

squirrelmail Server replied: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)

This qmailrocks forum thread gives a quick workaround. Just set “SMTP AUTHENTICATION” to login as noted below.

/usr/share/squirrelmail/config/config.php $no_list_for_subscribe = false; $smtp_auth_mech = 'login'; $imap_auth_mech = 'login'; $use_imap_tls = false;

Serving ASP pages in Linux

rupert — Tue, 13 Nov 2007 19:55:19 +0000

I never intended to do such a thing as what the title describes. However, since we need it at work temporarily, I have to crack up my linux skills to set this up. Principal reference is http://www.apache-asp.org/config.html.

In Debian,

1. install libapache2-mod-perl2 + libapache-asp-perl

sudo apt-get install libapache2-mod-perl2 sudo apt-get install libapache-asp-perl

2. configuration includes:
sudo vi /etc/apache2/sites-available/default

 76     PerlModule  Apache::ASP
 77      
 78        SetHandler  perl-script
 79        PerlHandler Apache::ASP
 80        PerlSetVar  Global .
 81        PerlSetVar  StateDir /data/asp
 82

3. Restart apache.

4. Make sure you have the correct permissions to: /data/asp
drwxrwxr-x 4 www-data www-data 4096 2007-11-13 15:33 asp

5. If you encounter the problems:

[Tue Nov 13 15:12:36 2007] [error] [client 127.0.0.1] Can't locate object method "get" via package "APR::Table" at /usr/share/perl5/Apache/ASP.pm line       2016.\n at /usr/share/perl5/Apache/ASP.pm line 2016\n\tApache::ASP::get_dir_config('APR::Table=HASH(0x81d96f8)', 'Global') called at /usr/share/perl5/A      pache/ASP.pm line 275\n\tApache::ASP::new('Apache::ASP', 'Apache2::RequestRec=SCALAR(0x81d9764)', '/data/wwwroot/asp/test.asp') called at /usr/share/pe      rl5/Apache/ASP.pm line 183\n\tApache::ASP::handler('Apache2::RequestRec=SCALAR(0x81d9764)') called at -e line 0\n\teval {...} called at -e line 0\n, re      ferer: http://127.0.0.1/asp/

Read nable-post. which patches /usr/share/perl5/Apache/ASP.pm as follows:

The lines 65-71:
   if($ENV{MOD_PERL}) {
   $ModPerl2 = ($mod_perl::VERSION >;= 1.99);
   if($ModPerl2) {
       eval "use Apache::ASP::ApacheCommon ();";
       die($@) if $@;
   }
   }
 
become
   if($ENV{MOD_PERL}) {
   $ModPerl2 = ($mod_perl::VERSION >;= 1.99);
   my $ver = $mod_perl::VERSION;
   if ($ver eq "") { $ver = $ENV{MOD_PERL_API_VERSION}; }
   $ModPerl2 = ($ver >;= 1.99);
   if($ModPerl2) {
       eval "use Apache::ASP::ApacheCommon ();";
       die($@) if $@;
   }
   }

6. If Step 5 still doesn’t work.

a. And this to /etc/apache2/conf.d/perl.conf:

PerlRequire /etc/apache2/startup.pl

b. startup.pl
#!/usr/bin/perl use Apache2::compat; 1;

7. To test. Paste the ff in test.asp under your webroot.

  -- sample here -->
 
  For loop incrementing font size:
 
  &lt;% for(1..5) { %&gt;
	-- iterated html text -->
	<font size="<%=$_%>"> Size = &lt;%=$_%&gt; font> 
  &lt;% } %&gt;
 
  -- end sample here -->

Too many authentication failures for user

rupert — Sat, 10 Nov 2007 23:29:00 +0000

Found this finally.. http://netthink.com/archives/191. On a quick note, edit ssh_config not sshd_config.

You could also try debugging ssh while connecting, through “-v” switch. For example:

ssh -v rupert@192.168.1.12

NTPD Sync

rupert — Mon, 06 Aug 2007 18:29:57 +0000

For desktops, I do have ntpd installed to sync the time…

1. apt-get install ntpdate

2. /etc/init.d/ntpd stop

3. ntpdate clock.fmt.he.net

Note: You need to stop ntpd before doing an ntpdate..

Understanding Iptables

rupert — Tue, 31 Jul 2007 10:13:08 +0000

My first hack with debian was smooth except for the firewall issues. RHEL/Fedora/CentOS stores its firewall policies in /etc/sysconfig/iptables, in Debian, you have to write down the chains and run it. Writing the chain rules is basically the same for both distros since it is iptables, however it is not pretty obvious for a newbie. So my problem was, I cannot ping a domainname but can ping an IP address instantly. I misinterpreted the root cause of the problem as a dns problem, so I disabled ipv6.. still a no go. Later I found out it was one of the rules in my iptables policies.

So here is the iptables firewall shell script that resolved the issue…

1. vi firewall.sh

iptables -F
iptables -N FIREWALL
iptables -F FIREWALL
iptables -A INPUT -j FIREWALL
iptables -A FORWARD -j FIREWALL
iptables -A FIREWALL -i lo -j ACCEPT
 
iptables -A FIREWALL -p icmp --icmp-type any -j ACCEPT
 
#iptables -A FIREWALL -p 50 -j ACCEPT
#iptables -A FIREWALL -p 51 -j ACCEPT
 
#iptables -A FIREWALL -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT
#iptables -A FIREWALL -p udp -m udp --dport 631 -j ACCEPT
 
iptables -A FIREWALL -m state --state ESTABLISHED,RELATED -j ACCEPT
 
iptables -A FIREWALL -p tcp -m tcp --dport 22 --syn -j ACCEPT
iptables -A FIREWALL -p tcp -m tcp --sport 80 -j ACCEPT
iptables -A FIREWALL -p tcp -m tcp --sport 3306 -j ACCEPT
iptables -A FIREWALL -p tcp -m tcp --sport 5432 -j ACCEPT
iptables -A FIREWALL -p tcp -m tcp --syn -j REJECT
iptables -A FIREWALL -p udp -m udp -j REJECT
iptables-save > /etc/firewall-rules
iptables-restore < /etc/firewall-rules

2. Run sh -v firewall_setup.sh

Here’s a brief explanation of the iptables flag taken from man.

-F, –flush [chain]
Flush the selected chain (all the chains in the table if none is given). This is equivalent to deleting all the rules one by one.

-N, –new-chain chain
Create a new user-defined chain by the given name. There must be no target of that name already.

-A, –append chain rule-specification
Append one or more rules to the end of the selected chain. When the source and/or destination names resolve to more than one address, a rule will be added for each possible address combination.

-j, –jump target
This specifies the target of the rule; i.e., what to do if the packet matches it. The target can be a user-defined chain (other than the one this rule is in), one of the special builtin targets which decide the fate of the packet immediately, or an extension (see EXTENSIONS below).

So I checked out my CentOS4 box and found out that I four (4) lines which I don’t understand. See commented lines above. Here’s an explanation of them..

Port 50 is Remote Mail Checking Protocol
Killing this may stop you checking if you have new mail on your provider’s POP server. Haven’t confirmed this…

Port 51 is IMP Logical Address Maintenance. Dunno what this is for..

Port 5353
This port is used for the Apple Bonjour network discovery protocol, as you can read here: http://www.apple.com/support/downloads/bonjourforwindows_readme.html

Port 631 IPP (Internet Printing Protocol). Enable this if you want to print from Linux.

Debian, Centos, Ubuntu

rupert — Fri, 27 Jul 2007 01:02:02 +0000

I didn’t have much time blogging for the past week. But since July 18, I am running Debian, Centos and Ubuntu on my desktop.

1. Install CentOS 5.

2. Manually partition as follows:
Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux (boot) /dev/sda2 14 3837 30716280 83 Linux (/) /dev/sda3 3838 4090 2032222+ 82 Linux swap

3. Put bootloader grub on mbr.

4. Reboot.

5. Install Ubuntu

6. Manually partition.
/dev/sda4 4091 19457 123435427+ 5 Extended /dev/sda5 19446 19457 96390 83 Linux /dev/sda6 19204 19444 1935801 82 Linux swap / Solaris /dev/sda7 15556 19202 29294496 83 Linux

7. Install bootloader on /boot of /dev/sda4

8. Reboot.

9. Install Debian 7

10. Manually partition as follows:
/dev/sda8 4091 4102 96327 83 Linux /dev/sda9 4103 4343 1935801 82 Linux swap / Solaris /dev/sda10 4344 7990 29294496 83 Linux

11. Reboot.

Hurray! Key point here is to install the bootloader on mbr first then, installing successive loaders in /boot of other distros.

Installing Trac on CentOS4

rupert — Tue, 26 Jun 2007 16:42:45 +0000

There is a problem with clearsilver on CentOS systems. I get neo_cgi.so module not found. Don’t force yourself, it would simply not work (Trac0.10.4 on CentOS, not unless we try the DAG repositories).

So, I have to use Trac 0.11, setuptools and Genshi.

Prerequisites:
- Must have python 2.3+
- Must have mod_python-3.3.1.tgz
- Must have httpd2.0.x+ or httpd2.2.x

A. Core Trac Installation

1. Install setuptools-0.6c6-py2.3.egg. Download the setuptools according to your python distribution and simply run:

sh setuptools-0.6c4-py2.3.egg

2. Install Genshi. There are numerous ways of installing Genshi.

easy_install Genshi

#wget http://ftp.edgewall.com/pub/genshi/Genshi-0.4.2-py2.3.egg #chmod +x Genshi-0.4.2-py2.3.egg #easy_install Genshi-0.4.2-py2.3.egg

3. Install Trac 0.11. We need to install trac from svn
#svn co http://svn.edgewall.org/repos/trac/trunk trac
#python ./setup.py install

This would install trac-admin and tracd in /usr/bin.

Trac Post Intall
#mkdir -p /var/www/trac #cd /var/www/trac #trac-admin /var/www/trac/poimgr initenv #chown -Rf nobody:root /var/www #chmod -Rf 755 /var/www

Just accept the defaults for now, we can change it later on /var/www/trac/poimgr/conf/trac.ini.

C. Apache Configuration

LoadModule python_module /usr/local/apache2/modules/mod_python.so
 

SetHandler mod_python
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /var/www/trac/poimgr
PythonOption TracUriRoot /trac/poimgr
#Order deny,allow
#Deny from all
#Allow from 192.168.1.0/24
AuthType Basic
AuthName "TRAC-POIMGR"
AuthUserFile "/repos/svn-auth-file"
require valid-user

Notes:
http://www.yolinux.com/TUTORIALS/LinuxSubversionAndTracServer.html

Depending on your installation, you may encounter some problems. I had problems with expat errors:

ExpatError (null): line 1,column 0.

Turns out that it was confused between the link libraries of apache and that of python.

#ps aux | grep http | head -3
#sof -p 29982 | grep expat
# strings libexpat.so.0.1.0 | grep expat_
expat_1.95.2
# strings /usr/lib/python2.3/lib-dynload/pyexpat.so | grep expat_
expat_1.95.7
 
Quickfix is to use symbolic links:
#cd /usr/local/apache2/lib/
#cp -Rf /usr/lib/libexpat.so.0.5.0 /usr/local/apache2/lib/
#ln -s libexpat.so.0.5.0 libexpat.so
#ln -s libexpat.so.0.5.0 libexpat.so.0
#su -l
#/etc/init.d/httpd restart

Configuring Trac.
1. I have to move /etc/svn-auth-file to /repos-auth-file. Change the permissions so “nobody” could access it.

2. How to configure my users? Well, since its an intranet application and my trac-users and developers is both in the svn-auth-file, I need a way to configure users easily. Follow these steps from trac-hack.
easy_install http://trac-hacks.org/svn/accountmanagerplugin/trunk

Role base authorisation in trac

trac-admin /var/www/trac/poiclient permission remove anonymous \
TICKET_CREATE TICKET_MODIFY WIKI_CREATE WIKI_MODIFY
 
for n in rupert andrew; do
trac-admin /var/www/trac/{app_name} permission add $n TRAC_ADMIN
done
 
for n in rupert andrew; do
trac-admin /var/www/trac/{app_name} permission add $n WIKI_DELETE
done
 
trac-admin /var/www/trac/poiclient permission add authenticated \
BROWSER_VIEW CHANGESET_VIEW FILE_VIEW LOG_VIEW MILESTONE_VIEW \
REPORT_SQL_VIEW REPORT_VIEW ROADMAP_VIEW SEARCH_VIEW \
TICKET_CREATE TICKET_MODIFY TICKET_VIEW TIMELINE_VIEW \
WIKI_CREATE WIKI_MODIFY WIKI_VIEW

3. Here’s my trac.ini. Things to look at is the notification and account-manager.

4. Deleting a Trac Ticket:
# sqlite3 trac.db delete from ticket_custom where ticket = [ticketID]; delete from ticket_change where ticket = [ticketID]; delete from ticket where id = [ticketID];

A crontab file has five fields for specifying day , date and time followed by the command to be run at that interval.

*     *   *   *    *  command to be executed
-     -    -    -    -
|     |     |     |     |
|     |     |     |     +----- day of week (0 - 6) (Sunday=0)
|     |     |     +------- month (1 - 12)
|     |     +--------- day of month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59)

cron invokes the command from the user’s HOME directory with the shell, (/usr/bin/sh).

cron supplies a default environment for every shell, defining:
HOME=user’s-home-directory
LOGNAME=user’s-login-id
PATH=/usr/bin:/usr/sbin:.
SHELL=/usr/bin/sh

Here is a cron scirpt which svn commits the database every 1am…

[root@dbserver1 ~]# crontab -l
#Cron check
#* * * * *  /bin/date >> /root/date.log
 
#Every 1AM svn commit the database
0 1 * * * /bin/sh /root/dbbackup.sh &gt; /root/dbbackup.log
 
#Every 6AM Update the date and time from ntpd
0 6 * * * /usr/sbin/ntpdate 0.asia.pool.ntp.org &gt; /root/dateupdate.log
 
[root@dbserver1 ~]# more /root/dbbackup.sh
#!/bin/sh
/bin/date &gt;&gt; /root/dbbackup.log
dbfolder=/data/mysqldata/cybersoftbj
/usr/bin/svn add $dbfolder/* &gt;&gt; /root/dbbackup.log
/usr/bin/svn commit --non-interactive --username ***** --password ***** -m "committed by autosvn cron script" $dbfolder/* &gt;&gt; /root/dbbackup.log
/bin/chown -Rf mysql:mysql $dbfolder
/bin/chmod -Rf 755 $dbfolder

Installing PostGres, PostGIS, pgRouting in Linux

rupert — Tue, 03 Apr 2007 15:05:09 +0000

A. Installing PostGres

A.1. Download and install the source: postgresql-8.2.3.tar.gz

[root@rupert-linux routing]tar -xvzf postgresql-8.1.2.tar.gz
[root@rupert-linux routing]LDFLAGS=-lstdc++
[root@rupert-linux routing]./configure --prefix=/usr/local/pgsql --with-perl --with-python --with-krb5 --with-openssl
[root@rupert-linux routing]make
[root@rupert-linux routing]make install
 
A.2. Post Compile Operations:
 
[root@rupert-linux routing]/usr/sbin/adduser postgres
 
[root@rupert-linux routing]mkdir /usr/local/pgsql/data
 
[root@rupert-linux routing]chown postgres /usr/local/pgsql/data/
 
[root@rupert-linux routing]su - postgres
 
[root@rupert-linux routing]/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data/

Note: If youre default locale is not EN, say chinese, then you would get:

The files belonging to this database system will be owned by user “postgres”.
This user must also own the server process.

The database cluster will be initialized with locale zh_CN.GB18030.
initdb: could not find suitable encoding for locale “zh_CN.GB18030″

A.3. Edit environment variables. Add the ff to your .bash_profile

[root@rupert-linux routing] vi /root/.bash_profile
PATH=$PATH:$HOME/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$JAVA_HOME/bin:/usr/local/pgsql/bin
export PGLIB=/usr/local/pgsql/lib
export PGDATA=/usr/local/pgsql/data
export PGPORT=5432
export PGOPTS="-i"

A.4. Start PostGres Automatically on Startup. Postgres Startup Script

[root@rupert-linux routing]touch /etc/init.d/postgresql
[root@rupert-linux routing] vi /etc/init.d/postgresql

PostGres Startup Script

#!/bin/sh
# postgresql    This is the init script for starting up the PostgreSQL
#               server
 
# chkconfig: - 85 15
# description: Starts and stops the PostgreSQL backend daemon that handles all database requests.
# processname: postmaster
# pidfile: /usr/local/pgsql/data/postmaster.pid

# Check that networking is up.
# Pretty much need it for postmaster.
[ ${NETWORKING} = "no" ] &amp;&amp; exit 0
 
[ -f /usr/local/pgsql/bin/postmaster ] || exit 0
 
# See how we were called.
case "$1" in
start)
pid=`pidof postmaster`
if [ $pid ]
then
echo "Postmaster already running."
else
echo -n "Starting postgresql service: "
su -l postgres -c '/usr/local/pgsql/bin/pg_ctl -o -i -D /usr/local/pgsql/data/ -l /usr/local/pgsql/data/logfile start'
sleep 1
echo
exit
fi
;;
 
stop)
echo -n "Stopping postgresql service: "
killproc postmaster
sleep 2
rm -f /usr/local/pgsql/data/postmaster.pid
echo
;;
 
restart)
$0 stop
$0 start
;;
 
*)
echo "Usage: postgresql {start|stop|restart}"
exit 1
esac
 
exit 0

Setting python_path on Unix

rupert — Thu, 29 Mar 2007 13:17:54 +0000

At the time of this writing.. download mod_python-3.3.1.tgz

./configure –with-apxs=/usr/local/apache2/bin/apxs
make
make install

You need to pass the PYTHONPATH to apache..

AddHandler python-program .py
PythonHandler TileCache.Service
PythonOption TileCacheConfig /usr/local/apache2/htdocs/tilecache/tilecache.cfg
PythonDebug On
PythonPath “sys.path + ['/usr/local/apache2/htdocs/tilecache/']”

In your bash shells, you could also check the PYTHONPATH…

[root@rupert-linux views]# python
Python 2.3.4 (#1, Mar 10 2006, 06:12:09)
[GCC 3.4.5 20051201 (Red Hat 3.4.5-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
&gt;&gt;&gt; import sys
&gt;&gt;&gt; print sys.path
['', '/usr/lib/python23.zip', '/usr/lib/python2.3', '/usr/lib/python2.3/plat-linux2', '/usr/lib/python2.3/lib-tk', '/usr/lib/python2.3/lib-dynload', '/usr/lib/python2.3/site-packages', '/usr/lib/python2.3/site-packages/gtk-2.0']

Unattended Linux Installation using KickStart

rupert — Tue, 06 Mar 2007 15:01:35 +0000

I have found this very handy in installing the same Linux OS on similar machines.

1. Download the isos from CentOS. I’m using CentOS4.4

2. Make available via http the CentOS installers. The directory should be as follows:

wwwroot/ /CentOS /headers /images /isolinux /NOTES /repodata .discinfo centosdocs-man.css GPS RELEASE-NOTES-en RELEASE-NOTES-en.html RPM-GPG-KEY RPM-GPG-KEY-centos4 yumgroups.xml

3. Create your kickstart files as follow:

#Generated by Kickstart Configurator
#platform=x86, AMD64, or Intel EM64T
 
#System  language
lang en_US.UTF-8
#Language modules to install

MBRFix – Removing Linux from Dual Boot

rupert — Sat, 03 Mar 2007 08:40:44 +0000

You have a dual boot notebook with Linux + XP, no floppy and just lazy using the Windows XP CD to do a fixmbr. Use the ‘mbrfix’ from http://www.ambience.sk/fdisk-master-boot-record-windows-linux-lilo-fixmbr.php. Run this utility to wipe out GRUB or LILO from the mbr and restore the Windows Boot loader into MBR. Sweet.

Installing a qmail server

rupert — Wed, 31 Jan 2007 23:35:28 +0000

Its been almost two years now since I installed a mail server. Nevertheless, qmail still rocks as qmailtoaster becomes more convenient to install. I also tried the install on a fresh CentOS4.4 machines, and it works like a charm.

--------------------------------------------------------------------
EZ QmailToaster Fresh Install on CentOS 4.3
Nick Hemmesch  June 08, 2006
--------------------------------------------------------------------
 
CentOS 4.3: This test install was performed on an
P4 3Ghz with 2GB ram on an Intel m/b. 
 
--------------------------------------------------------------------
This tutorial is for CentOS 4.3 (cnt40) i386 
 
To install CentOS 4.3 x86_64, replace cnt40 with cnt4064

fedora & cnt40 to fdr40, fdr4064, fdr50 or fdr5064 per your distro
--------------------------------------------------------------------
 
Notes:
 
You must have either a local dns server or a local caching name
server. If you need a caching namserver, we will add one in Step 8.
 
Be sure to replace "your-domain.com" with your real domain name,
and "your.fqdn.com" with your server's "Fully Qualified Domain Name".
 
--------------------------------------------------------------------
1. Download CentOS 4.3 CD iso's or the DVD iso.

  === NOTE ===
 
  This script turns on or off all necessary services. Then the script sets
  up your mysql root account, creates and grants privileges for your vpopmail
  mysql account, makes a symlink so your krb5 is read properly, edits your
  php.ini, sets inittab to start at runlevel 3, and sets up your firewall.
 
  Note: You might see some service errors while the script runs,
  don't worry about them.
 
  ============
 
  Update all your packages:
 
      yum -y update
 
  REBOOT

6. Get QmailToaster Packages:
--------------------------------------------------------------------
 
  cd /usr/src/qtms-install
 
  wget http://www.qmailtoaster.com/info/current-download-script.sh
 
      sh current-download-script.sh
 
  This script downloads all necessary packages into you current
  directory (should be /usr/src/qtms-install/).
 
--------------------------------------------------------------------
7. Install QmailToaster Packages:
--------------------------------------------------------------------
 
  wget http://www.qmailtoaster.com/centos/cnt40/cnt40-install-script.sh
 
      sh cnt40-install-script.sh
 
  Check your services:
 
      setup: Select Services
 
          See that the following services are selected: acpid anacron
 
          atd autofs cpuspeed crond djbdns freshclam haldaemon httpd
 
          iptables kudzu messagebus mysqld network ntpd qmail rawdevices
 
          smartd sshd syslog xinet
 
          Also: irqbalance (w/dual processors) xfs (w/xwindows)
 
--------------------------------------------------------------------
8. Add djbdns (if you don't want bind)
--------------------------------------------------------------------
 
  rpm -e --nodeps bind bind-chroot caching-nameserver
 
  rpmbuild --rebuild --with cnt40 djbdns*.src.rpm
 
  rpm -Uvh ../redhat/RPMS/i386/djbdns-localcache*.rpm
 
  echo "search your-domain.com" > /etc/resolv.conf
  echo "nameserver 127.0.0.1" >> /etc/resolv.conf
 
  REBOOT
 
--------------------------------------------------------------------
9. Setup QmailToaster:
--------------------------------------------------------------------
 
  qmailctl stat

      Send yourself an email - should show right away
 
      Send an email to yourself if you have another address
 
      Go to your other email account and reply to the message you sent
 
  If Isoqlog doesn't show right away, do this:
 
      sh /usr/share/toaster/isoqlog/bin/cron.sh
 
--------------------------------------------------------------------
10. Add domainkeys:
--------------------------------------------------------------------
 
  Make dir for yourdomain.com: 
 
      mkdir /var/qmail/control/domainkeys/your-domain.com 
 
  Make domainkey (Remove the "\"): 
 
      dknewkey /var/qmail/control/domainkeys/your-domain.com/private > \
                                                         your-domain-dk.txt 
 
      chown root:qmail /var/qmail/control/domainkeys/your-domain.com/private
      chmod 444 /var/qmail/control/domainkeys/your-domain.com/private
 
  Make dns entry: 
 
      BIND - in the your-domain.com zone file (see yourdomain-dk.txt):
 
         private._domainkey IN TXT "k=rsa; p=MEwwDQY . . . to end of key"
            (NOTE QUOTATION MARKS MUST BE THERE) 
 
      DJBDNS - in /var/djbdns/tinydns/root/data (make from your-domain-dk.txt): 
 
        '_domainkey.your-domain.com:o=-; r=postmaster@your-domain.com
        'private._domainkey.your-domain.com:k=rsa; p=MEwwDQY . . . to end of key 
 
  Test your mailserver:
 
      http://domainkeys.sourceforge.net/policycheck.html
      http://domainkeys.sourceforge.net/selectorcheck.html
 
      In squirrelmail, send a test email, select View Full Header and you
      should find something like the following:

Notes:
The only problem I stumbbled upon is when using vadddomain, as the mysql password was still set to “SsEeCcRrEeTt”. Edit these files before adding a domain. I dont use the web interface when adding a domain, i prefer it by command line.
[root@mail vpopmail]# find . | grep mysql ./etc/vpopmail.mysql.dist ./etc/vpopmail.mysql

After all the installs is completed, reboot and check if qmail is running.
Administrator links: http://your-mail-server-ip/admin-toaster/ -> this is the main administration interface http://your-mail-server-ip/qmailadmin/ -> administrative interface to manage accounts http://your-mail-server-ip/webmail/ -> an email account interface
