Centralized agent install

[ploeger]

Hi everybody!

I've started writing a script to centralize the installation of Zabbix agents. Everyone's welcomed to use and extend it:

Kind regards

Small corrections:

- replace 'useradd zabbix' with
[ `id zabbix >/dev/null 2>&1; echo $?` -eq 1 ] && useradd -m zabbix

- update-rc.d doesn't exist on RedHat-based systems
