Ruby on Rails is a popular rapid development web framework that allows web designers and developers to quickly implement dynamic, fully featured web applications written in the Ruby programming language.
This guide will help you get Ruby on Rails working with Passenger and the Nginx web server on Ubuntu 8.04 LTS (Hardy). We assume you've followed the steps in our getting started guide and that your system is up to date. All steps should be performed as root via an SSH session to your Linode VPS.
These instructions work with the Linode platform. If you don't have a Linode yet, sign up for a Linux VPS and get started today.
First, make sure you have the universe repository enabled in your /etc/apt/sources.list file. Your file should resemble the following:
File excerpt: /etc/apt/sources.list
## main & restricted repositories deb http://us.archive.ubuntu.com/ubuntu/ hardy main restricted universe deb-src http://us.archive.ubuntu.com/ubuntu/ hardy main restricted universe deb http://security.ubuntu.com/ubuntu hardy-security main restricted universe deb-src http://security.ubuntu.com/ubuntu hardy-security main restricted universe
If you added universe to the the items in your list, you'll need to update your repository database:
apt-get update apt-get upgrade
Issue the following command to install packages required for Ruby on Rails.
apt-get install wget build-essential ruby1.8 ruby1.8-dev irb1.8 rdoc1.8 zlib1g-dev libopenssl-ruby1.8 libopenssl-ruby libzlib-ruby libssl-dev
Create symbolic links to the installed version of Ruby:
ln -s /usr/bin/ruby1.8 /usr/bin/ruby ln -s /usr/bin/irb1.8 /usr/bin/irb
Now we'll need to install gems. The version in the Ubuntu 8.04
repositories is quite outdated, and does not work correctly. Issue the
following commands to download and install a fresh version. You may
wish to check the RubyForge files page
for the most recent version.
wget http://rubyforge.org/frs/download.php/69365/rubygems-1.3.6.tgz tar -xvf rubygems-1.3.6.tgz cd rubygems-1.3.6 ruby setup.rb ln -s /usr/bin/gem1.8 /usr/bin/gem
Update rubygems:
gem update --system
Install the rake, rack, and fastthread gems:
gem install rake gem install rack gem install fastthread --no-rdoc --no-ri
Proceed to the Phusion Passenger
site and locate the link for the current source code tarball.
Download it as follows (substitute the link for the current version):
cd /root wget http://rubyforge.org/frs/download.php/69546/passenger-2.2.11.tar.gz cd /opt tar xzvf ~/passenger-2.2.11.tar.gz
Run the Phusion Passenger installer for Nginx:
cd passenger-2.2.11/bin ./passenger-install-nginx-module
You'll be greeted by the Phusion Passenger Nginx installer program. Press "Enter" to continue with the installation.
When prompted for the Nginx installation method, we recommend you choose "1" to allow the installer to automatically download, compile, and install Nginx for you. Unless you have specific needs that would necessitate passing custom options to Nginx at compile time, this is the safest way to proceed.
Please do not remove the Passenger files from opt after the install. They need to stay in place or your install will not function correctly.
Nginx is now installed in /opt/nginx, but we need a way of controlling it. Create a file called /etc/init.d/nginx and copy the following script contents into it:
File: /etc/init.d/nginx
#! /bin/sh
### BEGIN INIT INFO
# Provides: nginx
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the nginx web server
# Description: starts nginx using start-stop-daemon
### END INIT INFO
PATH=/opt/nginx/sbin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/opt/nginx/sbin/nginx
NAME=nginx
DESC=nginx
test -x $DAEMON || exit 0
# Include nginx defaults if available
if [ -f /etc/default/nginx ] ; then
. /etc/default/nginx
fi
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
start-stop-daemon --start --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
start-stop-daemon --stop --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON
echo "$NAME."
;;
restart|force-reload)
echo -n "Restarting $DESC: "
start-stop-daemon --stop --quiet --pidfile \
/opt/nginx/logs/$NAME.pid --exec $DAEMON
sleep 1
start-stop-daemon --start --quiet --pidfile \
/opt/nginx/logs/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
;;
reload)
echo -n "Reloading $DESC configuration: "
start-stop-daemon --stop --signal HUP --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON
echo "$NAME."
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart|reload|force-reload}" >&2
exit 1
;;
esac
exit 0
Run the following commands to set system startup links:
chmod +x /etc/init.d/nginx /usr/sbin/update-rc.d -f nginx defaults
You can now start, stop, and restart Nginx just like any other server daemon. For example, to start the server, issue the following command:
/etc/init.d/nginx start
The configuration file for Nginx is located at /opt/nginx/conf/nginx.conf. This is the file you'll need to edit to add support for your Rails applications. A default server is already configured in this file, and it also contains examples for alternate virtual host and SSL configurations.
If your application uses MySQL, install the database server by following our MySQL on Ubuntu 8.04 LTS (Hardy) guide. Once it's installed and configured properly, issue the following commands:
apt-get install libmysqlclient15-dev libmysql-ruby
gem install mysql --no-rdoc --no-ri -- --with-mysql-dir=/usr/bin \
--with-mysql-lib=/usr/lib/mysql --with-mysql-include=/usr/include/mysql
