This is an updated version of the script posted at [Transmission SeedBox](http://transmissionseedbox.blogspot.de/2012/01/creating-seedbox-in-centos-6.html) for installing transmission on a CentOS (6.5) server. (Please see the orignial post for more details).

Three lines!:

# wget https://github.com/elijahpaul/install-transmission/raw/master/install-transmission.sh

# chmod u+x install-transmission.sh

# ./install-transmission.sh

Done.

You can now use the transmisson-remote-gui front-end app to access your install remotely, or access the web interface via the web URL http://<YOUR-SERVER-IP>:9091

Go ahead and try downloading a torrent:
Ubuntu 14.04 LTS Server (64bit)

EDIT: What's updated from the original?

• Added xz to the install on line 9 to enable tar to untar the transmission-2.84.tar.xz file
• ~~Updated the libevent package from version libevent-2.0.19-stable.tar.gz to libevent-2.0.21-stable.tar.gz
  And switched the download URL from github to sourceforge (due to SSL handshake errors with some versions of wget and the orignal URL)~~
• 9th July 2015: Updated libevent to version libevent-2.0.22-stable.tar.gz & URL from dead sourceforge link to github (see here)
• Updated the CSF firewall restart command from service csf restart to csf -r
