My notes on setting up a simple production server with centos, nginx, passenger and mysql for rails.
echo "alias ll='ls -l'" >> ~/.bash_aliases
edit .bashrc and uncomment the loading of .bash_aliases
If you have trouble with PATH that changes when doing sudo, see http://stackoverflow.com/questions/257616/sudo-changes-path-why then add the following line to the same file
echo "alias sudo='sudo env PATH=$PATH'" >> ~/.bash_aliases
sudo yum update
yum install tzdata system-config-date
yum install ntp
sudo ntpdate ntp.ubuntu.com # Update time
Verify that you have to correct date and time with
date
sudo hostname your-hostname
Add 127.0.0.1 your-hostname
sudo vim /etc/hosts
Write your-hostname in
sudo vim /etc/hostname
Verify that hostname is set
hostname
This should be installed before Ruby Enterprise Edition becouse that will install the mysql gem.
sudo yum install mysql mysql-devel
Add the following lines to ~/.gemrc, this will speed up gem installation and prevent rdoc and ri from being generated, this is not nessesary in the production environment.

Check for newer version at http://www.rubyenterpriseedition.com/download.html
Install package required by ruby enterprise, C compiler, Zlib development headers, OpenSSL development headers, GNU Readline development headers
yum groupinstall "Development Tools"
yum install zlib-devel wget openssl-devel pcre pcre-devel readline-devel
Download and install Ruby Enterprise Edition
wget http://rubyforge.org/frs/download.php/66162/ruby-enterprise-X.X.X-ZZZZ.ZZ.tar.gz
tar xvfz ruby-enterprise-X.X.X-ZZZZ.ZZ.tar.gz
rm ruby-enterprise-X.X.X-ZZZZ.ZZ.tar.gz
cd ruby-enterprise-X.X.X-ZZZZ.ZZ/
sudo ./installer
Change target folder to /opt/ruby for easier upgrade later on
Add Ruby Enterprise bin to PATH
echo "export PATH=/opt/ruby/bin:$PATH" >> ~/.profile && . ~/.profile
Verify the ruby installation
ruby -v

sudo /opt/ruby/bin/passenger-install-nginx-module
Select option 1. Yes: download, compile and install Nginx for me. (recommended)
When finished, verify nginx source code is located under /tmp
$ ll /tmp/
drwxr-xr-x 8 deploy deploy 4096 2009-04-18 17:48 nginx-0.6.36
-rw-r--r-- 1 root root 528425 2009-04-02 08:49 nginx-0.6.36.tar.gz
drwxrwxrwx 7 1169 1169 4096 2009-04-18 17:56 pcre-7.8
-rw-r--r-- 1 root root 1168513 2009-04-18 17:51 pcre-7.8.tar.gz
Run the passenger-install-nginx-module once more if you want to add --with-http_ssl_module
$ sudo /opt/ruby/bin/passenger-install-nginx-module
Select option 2. No: I want to customize my Nginx installation. (for advanced users)
When installation script ask, "Where is your Nginx source code located?" Enter:
/tmp/nginx-0.6.36
On, extra arguments to pass to configure script add
--with-http_ssl_module

cd
git clone git://github.com/xdite/rails-nginx-passenger-centos.git
sudo mv rails-nginx-passenger-centos/nginx/nginx /etc/init.d/nginx
sudo chown root:root /etc/init.d/nginx
Verify that you can start and stop nginx with init script
sudo /etc/init.d/nginx start
* Starting Nginx Server...
...done.
sudo /etc/init.d/nginx status
nginx found running with processes: 11511 11510
sudo /etc/init.d/nginx stop
* Stopping Nginx Server...
...done.
sudo /sbin/chkconfig nginx on
If you want, reboot and see so the webserver is starting as it should.
If you want to install the latest version of ImageMagick. I used MiniMagick that shell-out to the mogrify command, worked really well for me.
# If you already installed imagemagick from yum
sudo yum remove imagemagick
yum install tcl-devel libpng-devel libjpeg-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel
yum install libjpeg-devel libpng-devel glib2-devel fontconfig-devel zlib-devel libwmf-devel freetype-devel
Use wget to grab the source from ImageMagick.org.
wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
Once the source is downloaded, uncompress it:
tar xvfz ImageMagick.tar.gz
Now configure and make:
cd ImageMagick-6.6.3-10
./configure --prefix=/usr --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes
make
sudo make install
To avoid an error such as:
convert: error while loading shared libraries: libMagickCore.so.2: cannot open shared object file: No such file or directory
sudo /sbin/ldconfig
Install RMagick
sudo /opt/ruby/bin/ruby /opt/ruby/bin/gem install rmagick
rails -d mysql testapp
cd testapp
Enter your mysql password
vim database.yml
rake db:create:all
ruby script/generate scaffold post title:string body:text
rake db:migrate RAILS_ENV=production
Check so the rails app start as normal
ruby script/server
sudo vim /opt/nginx/conf/nginx.conf
Add a new virutal host
server {
listen 80;
# server_name www.mycook.com;
root /home/deploy/testapp/public;
passenger_enabled on;
}
Restart nginx
sudo /etc/init.d/nginx restart
Check you ipaddress and see if you can acess the rails application
