Ruby on Rails, or simply Rails, is an open source web application framework built on top of the Ruby programming language. In this article, we will show you how to install Ruby, Ruby on Rails and Nginx with Passenger support on Debian-based distributions (Ubuntu VPS and Debian VPS).
First install Ruby using RVM
curl -L https://get.rvm.io | bash -s stable --ruby
To start using RVM run:
source /usr/local/rvm/scripts/rvm
To verify everything is done correctly, use the command “ruby -v”.
The output should be similar to the following:
# ruby --version ruby 2.0.0p247 (2013-06-27 revision 41674) [i686-linux]
Install Rails and Passenger
gem install rails passenger
Install Nginx with Passenger.
apt-get install libcurl4-openssl-dev rvmsudo passenger-install-nginx-module
Select the first option when prompted and press Enter.
(1. This installer will compile and install Nginx with Passenger support.)
If the installation is successful, you will see a message similar to the following:
Nginx with Passenger support was successfully installed.
Create an init script (/etc/init.d/nginx) with the following content:
#! /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
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
To start the Nginx service run:
chmod a+x /etc/init.d/nginx service nginx start update-rc.d nginx defaults
Install MySQL/MariaDB and Postgresql Support
apt-get install libmysqld-dev # or libmariadbd-dev apt-get install libpq-dev gem install mysql2 pq
Of course you don’t have to do any of this if you use one of our Linux VPS services, in which case you can simply ask our expert linux admins to install this for you. They are available 24×7 and will take care of your request immediately.
