I have put a script together that allows me to install a specified version of Zabbix on a Ubuntu server, if you choose not to install the server the script assumes you want to install the Zabbix agent. It also provides an option to compile with IPv6 support.

Although there is some error checking, they can always be more added. If you decide to improve the script further please leave a comment with a link to the new improved version.

It is possibly that the CODE section of this blog provider mucks up some of the special formatting characters, if you have problems check what you see on this page to what has been copied into your script file.

As usual make sure you chmod +x the script file and I suggest you run this with root privelidges.

#!/bin/bash

#TODO
# error checking always needs improving


#Adapted from script found online
# CHANGES by Paul Miller:
#enhanced to offer IPv6 support
#Changed to support mysql
#added option for version support
#server or agent install
#added some error checking
