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 ..

-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      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>

Rails Note #4: Deploying a Rails Application in a Subdirectory

rupert — Fri, 07 Nov 2008 08:37:36 +0000

There are many ways to deploy RoR applications. I have googled all over the place and so far the easiest setup that I could find that would suit my needs (existing Apache2 + ColdFusion + TileCache) would be to use

1. Apache PROXY
2. Mongrel

CentOS Installation Instructions

1. Make sure Apache has mod_proxy

 ./configure --prefix=/usr/local/apache2 --enable-so --enable-rewrite --with-mpm=prefork --enable-proxy --enable-proxy-connect --enable-proxy-ftp --enable-proxy-httpd --enable-proxy-ajp --enable-proxy-balancer --enable-cgi

1. Apache Proxy


    ServerName test
    ProxyRequests Off 
        
            Order deny,allow
            Allow from all
        
    ProxyPass /localdumplings http://localhost:3000/localdumplings
    ProxyPassReverse /localdumplings http://localhost:3000/localdumplings
    #ProxyPass /localdumplings/ http://localhost:3000/
    #ProxyPassReverse /localdumplings/ http://localhost:3000/

2. Starting mongrel on a subdir
mongrel_rails start –prefix=/localdumplings

Debian Installation Instructions

1. Install libapache2-mod-proxy-html is easier…

sudo apt-get install libapache2-mod-proxy-html

2. Enable modules to load in apache2

sudo a2enmod proxy
sudo a2enmod proxy_balancer
sudo a2enmod proxy_http
sudo a2enmod rewrite
sudo /etc/init.d/apache2 stop
sudo /etc/init.d/apache2 start

3. Add the application in /etc/apache2/mods-available/proxy.conf


        #turning ProxyRequests on and allowing proxying from all may allow
        #spammers to use your proxy to send email.
 
        ProxyRequests Off 
 
        
                AddDefaultCharset off 
                Order deny,allow
                Allow from all
                #Allow from .example.com
        
 
        # Enable/disable the handling of HTTP/1.1 "Via:" headers.
        # ("Full" adds the server version; "Block" removes all outgoing Via: headers)
        # Set to one of: Off | On | Full | Block
        ProxyPass /localdumplings http://localhost:3000/localdumplings
        ProxyPassReverse /localdumplings http://localhost:3000/localdumplings
 
        ProxyVia On

Starting a mongrel_rails on boot
Slicehost ( http://articles.slicehost.com/2007/9/21/debian-etch-apache-vhosts-rails-and-mongrels ) has a very good article regarding this.

mongrel_rails start -d -e production -p 8001 -P log/mongrel8001.pid -l log/mongrel.log

Post Install Apache2.x, ColdFusion 8

rupert — Wed, 28 May 2008 13:42:37 +0000

After binding Apache2.x and ColdFusion 8, I find it very useful to follow the post-install instructions below:

1. Copying ColdFusion Admin directory to /wwwroot (webroot)

# ln -s /var/www /wwwroot
# cp -Rf /opt/coldfusion8/wwwroot/CFIDE /wwwroot/
# rm /wwwroot/index.html
# cd /wwwroot
# ln -s CFIDE cfide

2. Adding index.cfm to DirectoryIndex.

# vim /etc/apache2/mods-available/dir.conf
DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm index.cfm

3. Restart apache

/etc/init.d/apache2 stop 
/etc/init.d/apache2 start

4. Browse Admin page for the first time

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

Installing Subversion on Debian

rupert — Sat, 26 Jan 2008 17:26:15 +0000

I was greeted with “No space left on device” on my cron log. Turns out that my svn server obviously ran out of disk space. The old svn server was running on CentOS4.3, Subversion 1.3.2, Trac-0.11.devxxx. I decided to migrate the svn data to a new server, so I installed Debian4.01 on a small server with 72 GB HD, no partitions (just / and swap, so the svn have room to grow…). Here are the steps I took for the migration:

A. A fresh start…
1. Installed Debian. Fixed network and ssh.
2. apt-get install apache2
3. apt-get install subversion
4. apt-get install python python-setuptools python-mysqldb python-subversion
5. apt-get install libapache2-svn libapache2-mod-python

B. Making SVN work…
1. svnadmin create /repos –fs-type fsfs

2. Since I have a fresh apache configuration, I edited it accordingly from /etc/apache2/mods-available/dav_svn.conf:

#SVN dir

  DAV svn
  SVNPath /repos
  SVNAutoversioning on
  AuthType Basic
  AuthName "SVN - Your Project"
  AuthUserFile /repos/svn-auth-file
  Require valid-user

3. Restart apache

4. To test if svn is running, import a project inside the repository.
svn import -m "initial import" /tmp/project http://127.0.0.1/repos/project

C. Migrating the data

After I got my fresh debian svn machine, I need to move the svn data and trac to the new server. http://svnbook.red-bean.com/nightly/en/svn.reposadmin.html

1. Transfer /repos/svn-auth-file and /repos/svn-authorization-file to the new server
2. Transferred trac.tar.gz (/var/www/trac) to the new server

To move the svn data from one server to another, I tried the ff choices…
1. svnadmin dump /repos /reposbak. Will work if disk space is not an issue. My /repos is 25 GB, and my other 30 GB partition was wiped out, even though the dump was not finished yet.

2. svnadmin hotcopy --clean-logs /repos /repos2. Accdg to the docs, this is exactly the same repository without the BdB logs. I then transferred the hotcopy from choice 2 above to the new server and works flawlessly to my surprise. So now, I still have all my revisions

Installing R on Windows and Debian

rupert — Fri, 16 Nov 2007 01:15:59 +0000

‘R’ is a statistical package. For an overview, please go to www.r-project.org
My intention was to remove the point outliers from a given set of point geometries.

I just recently installed R both on my Windows XP and Debian. Regina’s www.bostongis.com is an excellent tutorial in getting involved with R. I do suggest you head first to PLR Part 1: Up and Running with PL/R (PLR) in PostgreSQL: An almost Idiot’s Guide to get you started.

The install instructions for Windows works flawlessly. I have to hold back to R-2.5 though as I plan to use RPy (Python for R), see details below. To install ‘R’ in Debian, there’s a couple of settings that we need to take care of…

1. Install r-base
sudo apt-get install r-base

2. Install plr on postgres
sudo apt-get install postgresql-8.2-plr

3. Using R in a database
psql -d beijing -U lbs -h 127.0.0.1 < /usr/share/postgresql/8.2/plr.sql

4. Set the R_HOME environment variable
/etc/postgresql/8.2/main/environment
R_HOME='/usr/lib/R'

5. Restart Debian.

RPy, R for Python, is another alternative to use R in Python. I installed it both in Windows and Debian. Note that I reverted to R-2.5 on Windows to be compatible with RPy. For Debian, Im currently using R-2.6.

For the Windows Binary Installation,

1. Read the RPy Main Site

2. Install prerequisites:

- NumPy
- Win32 Extensions Download

3. Afterwards, install the main package, RPy Download

In Debian, its a straight forward…sudo apt-get install python-rpy

Debian MySQL

rupert — Mon, 29 Oct 2007 22:21:27 +0000

A default install of mysql on debian would have bind-address set to 127.0.0.1. This is why you can’t accept remote connections to your mysql. In order to establish remote connections to mysql on debian servers, please comment the bind-address as shown below.

 42 language    = /usr/share/mysql/english
 43 skip-external-locking
 44 #

Debian Howto: Installing Mapserver

rupert — Tue, 31 Jul 2007 22:51:04 +0000

By default, we can install mapserver using etch stable from a debian mirror using apt-get. Final results were almost close as expected, however, I need mapserver with TIFF support to be able to display my satellite images. Thus, recompilation is necessary. Below is the binary version difference for both installation procedures.

Nevertheless, it is worth noting that ‘apt-get’ significantly boost the installation of mapserver. I highly suggest to install mapserver using apt-get and use source compilation only if necessary.

a) mapserver installed using apt-get

Debian Howto: Apache 2.2 + ColdFusion Updated for SID

rupert — Tue, 31 Jul 2007 18:51:54 +0000

Wow, this is really nice. I was able to install Apache2.2 + ColdFusion on my current Debian 4.0 Etch.

Here’s an introduction on using apt…

Use apt-cache to search the local database for available packages.
apt-cache search [search terms] will find packages that sound like what you want and:
apt-cache show [packagename] will return more details on a particular package.
apt-cache showpkg [packagename] will return more details on a particular package.
apt-cache policy [packagename] will return which versions are available along with the priority of each version.
apt-setup will enable you to change mirrors. The alternative is to edit /etc/apt/sources.list manually (which I prefer).
apt-get clean clears the local repository of all retrieved package files.
apt-get autoclean clears the local repository of retrieved package files of programs that are no longer installed.
dpkg -l [packagename] will list the version and a short description of the package we have installed.

Installing Apache2.2

1. apt-get install g++

2. apt-get install apache2

Setting up apache2-utils (2.2.3-4) ...
Setting up apache2.2-common (2.2.3-4) ...
Setting Apache2 to Listen on port 80. If this is not desired, please edit /etc/apache2/ports.conf as desired. Note that the Port directive no longer works.

Setting up apache2-mpm-worker (2.2.3-4) ...
Starting web server (apache2)...apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

3. /etc/init.d/apache2 start

4. ps -ef | grep apache2

5. Post Install:
#mkdir -p /usr/local/apache2 #ln -s /var/log/apache2 /usr/local/apache2/logs #ln -s /var/www /usr/local/apache2/htdocs #ln -s /usr/lib/cgi-bin /usr/local/apache2/cgi-bin

Installing ColdFusion 8
1. Install ColdFusion 8 normally. Make the user as nobody

2. To start ColdFusion8 on boot, download this startup script (coldfusion8_startup_debian).
Drop it to /etc/init.d/ and start coldfusion

3. Bind ColdFusion to Apache. Modify the existing apache_connector.sh.

#!/bin/sh
 
#
# Configure the Apache connector.
#       -dir should be the *directory* which contains httpd.conf
#       -bin should be the path to the apache *executable*
#       -script should be the path to the script which is used to
#               start/stop apache
#
../../runtime/bin/wsconfig \
        -server coldfusion \
        -ws apache \
        -dir /etc/apache2 \
        -bin /usr/sbin/apache2 \
        -script /usr/sbin/apache2ctl \
        -coldfusion
 
exit $#

4. Check if the bind is successful by inspecting /etc/apache2/httpd.conf . You should see something similar below…

# JRun Settings
LoadModule jrun_module /opt/coldfusion8/runtime/lib/wsconfig/1/mod_jrun22.so
<IfModule mod_jrun22.c>
    JRunConfig Verbose false
    JRunConfig Apialloc false
    JRunConfig Ignoresuffixmap false
    JRunConfig Serverstore /opt/coldfusion8/runtime/lib/wsconfig/1/jrunserver.store
    JRunConfig Bootstrap 127.0.0.1:51011
    #JRunConfig Errorurl url 
    #JRunConfig ProxyRetryInterval 600 
    #JRunConfig ConnectTimeout 15 
    #JRunConfig RecvTimeout 300 
    #JRunConfig SendTimeout 15 
    AddHandler jrun-handler .jsp .jws .cfm .cfml .cfc .cfr .cfswf
IfModule>

5. Follow Post install considerations

Installing ColdFusion7.0.2

References:
http://demirkapi.net/tutorials/coldfusion_debian_installation.cfm
http://www.easycfm.com/print/index.cfm?tutorial_id=376

1. apt-get install libstdc++6 libstdc++5 libstdc++2.10-glibc2.2(etch)

On etch, by default there is already xlibs, if we have desktop. On sid, if there is also no X, we need to install libxp6 libxt6 libxtst6. If you don’t install these libraries, you will get a graphing library error during coldfusionmx startup.

2. By default debian has a ‘nobody’ user also

From http://forums.gentoo.org/viewtopic-t-312113.html, and if you get a libc.so.6 No suc file or directory found problem

3. Modify /opt/coldfusionmx7/bin/coldfusion and comment out LD_ASSUME_KERNEL
174 # Some Java JVMs (both from Sun and IBM) don't work with the new floating stack 175 # feature of the i686 version of glibc. Force glibc to use the deprecated stack model. 176 # Check if the OS is SuSE8.1 or SuSE 9 - if it is, do not use the deprecated stack model. 177 #SUSEFLAG=`grep 'SuSE Linux 8.1\|UnitedLinux 1.0\|SuSE Linux 9\|SUSE LINUX Enterprise Server 9' /etc/SuSE-release /etc/UnitedLinux-release /etc/UnitedLinux-release 2> /dev/null` 178 179 #if [ ! "$SUSEFLAG" ]; then 180 # LD_ASSUME_KERNEL=2.2.9 181 # export LD_ASSUME_KERNEL 182 #fi

4. Boot on Start.

#cp -Rf /opt/coldfusionmx7/bin/coldfusion /etc/init.d/coldfusionmx7
#update-rc.d coldfusionmx7 start 80 2 3 4 5 . stop 15 0 1 6 .

5. You need the latest wsconfig.jar that will work on Apache2.2. It was discussed from a technote here. Configure apache with coldfusion

Call java and execute wsconfig.jar

/opt/coldfusionmx7/runtime/jre/bin/java cd {cf_root}/runtime/lib

java -Dtrace.ci=1 -jar wsconfig.jar -server coldfusion -ws apache

-dir /etc/apache2/

-bin /usr/sbin/apache2

-script /usr/sbin/apache2ctl

-coldfusion -v

Installing Debian

rupert — Tue, 31 Jul 2007 12:21:01 +0000

This is already an update on my First Howto with debian. So far, I could atest that Debian has been very good to me, and lessen my daily admin tasks.

1. Install base system. I prefer a minimal install.

2. Setup Networking

2.1 Disable IPV6
vi /etc/modprobe.d/aliases
alias ipv6 off
alias net-pf-10 off
 
2.2 Setup IP
vi /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
 
# The loopback network interface
auto lo
iface lo inet loopback
 
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
        address 192.168.1.211
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1

2.3 Modify Hosts

#vi /etc/hosts
127.0.0.1           localhost
127.0.1.1           rupert-debian
192.168.1.211     rupert-debian
222.73.255.64     mirrors.geekbone.org
61.132.102.124   debian.cn99.com
128.31.0.36       security.debian.org
 
# The following lines are desirable for IPv6 capable hosts
#::1     ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters
#ff02::3 ip6-allhosts

You can delete the commented (#) lines, if you don’t have ipv6 on your network…

2.4 Setup Basic Firewall
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 &gt; /etc/firewall-rules
iptables-restore &lt; /etc/firewall-rules

sh -v firewall_setup.sh

To set it up on boot:
vi /etc/network/interfaces
…
iface lo inet loopback
pre-up iptables-restore < /etc/firewall-rules
…

I did catch a slight problem on this, for more details please read this post.

3. Specify the nearest source list

<a href="/wordpress/?p=83">
vi /etc/apt/sources.list
#deb http://mirrors.geekbone.org/debian etch main
#deb-src http://mirrors.geekbone.org/debian etch main
 
deb http://mirrors.geekbone.org/debian etch main
deb-src http://mirrors.geekbone.org/debian etch main
a>

4. Let’s get ssh up and running first.

<a href="/wordpress/?p=83">
apt-get update
apt-get install ssh
a>

5. Once you have networking up and running, then I advise to upgrade to lenny (testing) as stated from the source list[3] above.

<a href="/wordpress/?p=83">
apt-get upgrade libc6
apt-get dist-upgrade
a>

6. Reboot

7. Do you want this machine to be your desktop? If yes, let’s get gnome.

<a href="/wordpress/?p=83">
#aptitude install gnome
#aptitude install gnome-core
#aptitude install x-window-system
a>

8. Reboot. You should see a graphical Gnome Login

9. Utilities

<a href="/wordpress/?p=83">
#apt-get install htop nmap unzip subversion build-essential cmake locate
#apt-get install libboost-graph*
a>

10. Servers
#apt-get install apache2
#apt-get install postgresql-8.2
#apt-get install postgresql-8.2-postgis
#apt-get install postgresql-server-dev-8.2
#apt-get install mysql-server

11. Removing unwanted services
#update-rc.d -f portmap remove
#update-rc.d -f cupsys remove
#update-rc.d -f exim4 remove

12. Configuring vimrc with syntax highlighting


set nocompatible
set nu
set ts=4
syntax on

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.
