If you're doing a lot of command line work with icinga configurations and you happen to use vim a lot, it is super useful to use the vim syntax highlighting that comes with icinga2. Here's how to set it up on a CentOS/RHEL 7 box.
- First, make sure you have the icinga2-common package installed. This is a dependency of the icinga2 package, so it should be as easy as pie:
[root@icinga2 ~]# yum install icinga2
Loaded plugins: fastestmirror
icinga-stable-release | 951 B 00:00:00
icinga-stable-release/7/primary | 21 kB 00:00:00

Complete!- Next, make sure vim is installed. This might sound like a major d'oh, but it's not installed by default on RHEL 7 machines so just trying to be complete.
