PLEASE NOTE: This is very old and out of date. I'm keeping it here for reference but I would definitely recommend updating this substantially before using it for anything mission-critical.
Similar to jnstq's rails-nginx-passenger-ubuntu recipe but for nginx+passenger/apache+passenger on CentOS. Also influenced by the deploy scripts used by EngineYard Solo. Includes a deploy script and init script for nginx as well as configuration files for apache.
sudo yum update
sudo yum groupinstall 'Development Tools'
Git is not included in the default CentOS repositories so we must add the (official) EPEL repository before installing git.
su -c 'rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm'
sudo yum install git
sudo yum install mysql-server mysql mysql-devel
sudo /etc/init.d/mysqld start
/usr/bin/mysqladmin -u root password 'newpassword'
/sbin/chkconfig mysqld on
sudo yum install readline-devel
You can get the latest version of REE from the official site. Use the latest version (at the time of writing it is 1.8.6-20090610)
mkdir ~/src && cd ~/src
wget http://rubyforge.org/frs/download.php/58677/ruby-enterprise-1.8.6-20090610.tar.gz
tar -zxvf ruby-enterprise-1.8.6-20090610.tar.gz
cd ruby-enterprise-1.8.6-20090610
sudo ./installer
sudo ln -s /opt/ruby-enterprise-1.8.6-20090610/ /opt/ruby-enterprise
sudo ln -s /opt/ruby-enterprise/bin/ruby /usr/bin/ruby
sudo ln -s /opt/ruby-enterprise/bin/gem /usr/bin/gem
sudo ln -s /opt/ruby-enterprise/bin/irb /usr/bin/irb
We're going to want to add REE to the path so we can use things like 'ruby' and 'gem' from the commandline.
su -c 'echo "export PATH=/opt/ruby-enterprise/bin:\$PATH" >> /etc/profile'
Create a new deploy user and copy your SSH public key into the new
sudo /usr/sbin/adduser deploy
cp ~/.ssh/authorized_keys /tmp/
sudo -u deploy -i
mkdir .ssh
chmod go-rwx .ssh
cat /tmp/authorized_keys > ~/.ssh/authorized_keys
chmod go-w ~/.ssh/authorized_keys
exit
rm /tmp/authorized_keys
nginx does not have the ability to dynamically load modules like apache so we have to recompile it. Thankfully Ruby Enterprise Edition has a handy script that will automatically do this for you and set up REE to work with it.
sudo /opt/ruby-enterprise/bin/passenger-install-nginx-module
Note - our firewall blocks outgoing FTP access. The PCRE installation uses a hardcoded FTP address to download its tar.gz. You can edit the file using sudo vi /opt/ruby-enterprise/bin/passenger-config --root/bin/passenger-install-nginx-module and change the url line in the download_and_extract_pcre method to url = "http://voxel.dl.sourceforge.net/sourceforge/pcre/#{basename}".
cd ~/src
git clone git://github.com/swhitt/centos-nginx-passenger.git
sudo cp -R centos-nginx-passenger/nginx/* /opt/nginx/conf/
Now you can edit the files in /opt/nginx/conf.
In order to get nginx to boot up on reboot, use the init script in this git repository.
sudo cp centos-nginx-passenger/init/nginx /etc/init.d
sudo chmod +x /etc/init.d/nginx
sudo /sbin/chkconfig nginx on
Start up nginx right now with:
sudo mkdir /var/log/nginx
sudo /etc/init.d/nginx start
First install apache and start it up:
sudo yum install httpd mod_ssl
sudo yum install httpd-devel
sudo /sbin/chkconfig httpd on
sudo /etc/init.d/httpd start
Now install the passenger module for apache.
sudo gem update
sudo gem install passenger
sudo passenger-install-apache2-module
You can copy the contents of the apache folder to /etc/httpd/conf. If you are hosting multiple sites on the same machine, create as many config files in the sites/ subdirectory as you need. They can be modeled after app.conf, just updated to point to the correct public directory.
In order to use the activerecord-oracle driver you need to have ruby-oci8 installed, which requires the Oracle Instant Client to be installed. You can get the latest copy here, OTN login required. Get the Instant Client Basic, SDK and SQL*Plus rpms.
sudo rpm -i oracle-instantclient11.1-basic-11.1.0.7.0-1.i386.rpm
sudo rpm -i oracle-instantclient11.1-devel-11.1.0.7.0-1.i386.rpm
sudo rpm -i oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.i386.rpm
Next you need to set the LD_LIBRARY_PATH variable by editing /etc/profile
su -c 'echo "export LD_LIBRARY_PATH=/usr/lib/oracle/11.1/client/lib:\$LD_LIBRARY_PATH" >> /etc/profile'
Put your tnsnames.ora file in /etc and then set your TNS_ADMIN environment variable
su -c 'echo "export TNS_ADMIN=/etc" >> /etc/profile'
Get the latest ruby-oci8 tar.gz from rubyforge.
cd ~/src
wget http://rubyforge.org/frs/download.php/56925/ruby-oci8-1.0.6.tar.gz
tar -zxvf ruby-oci8-1.0.6.tar.gz
cd ruby-oci8-1.0.6
make
sudo -E make install
Place the oracle/ruby_with_oracle_env script in /home/deploy and change nginx.conf's passenger_ruby line to passenger_ruby /home/deploy/ruby_with_oracle_env.
wget http://www.zacharywhitley.com/linux/rpms/fedora/core/6/i386/msttcorefonts-2.0-1.noarch.rpm
rpm -i msttcorefonts-2.0-1.noarch.rpm
ln -s /usr/share/fonts/msttcorefonts /usr/share/fonts/default/TrueType
yum install ImageMagick
yum install ImageMagick-devel
gem install rmagick -v 1.15.17 --no-rdoc --no-ri
nano /opt/ruby-enterprise-1.8.6-20090610/lib/ruby/gems/1.8/gems/rmagick-1.15.17/ext/RMagick/rmmain.c
Change sprintf(long_version)... to

If you need memcached, install it like this:
sudo yum install memcached
sudo /sbin/chkconfig memcached on
sudo /etc/init.d/memcached start
If you want you can set your default RAILS_ENV to the environment that you plan on using on this computer. This will make it easier when you are logged in to the shell - you won't have to specify RAILS_ENV while running rake. To do this, add
export RAILS_ENV='production'
to /etc/profile, replacing production with the environment you want.
