====== Install Zabbix 2.2/2.4 Agent in Debian 7 (Wheezy) ======

Edit ''/etc/apt/sources.list.d/zabbix.list'' and paste the following lines (for 2.2)

  deb http://repo.zabbix.com/zabbix/2.2/debian/ wheezy main contrib non-free
  deb-src http://repo.zabbix.com/zabbix/2.2/debian/ wheezy main contrib non-free

or (for 2.4)

  deb http://repo.zabbix.com/zabbix/2.2/debian/ wheezy main contrib non-free
  deb-src http://repo.zabbix.com/zabbix/2.2/debian/ wheezy main contrib non-free

Then add the gpg key
  gpg --keyserver keys.gnupg.net --recv D13D58E479EA5ED4
  gpg --export --armor D13D58E479EA5ED4 | sudo apt-key add -
and update the apt package list with
  apt-get update

Install the Zabbix agent
  apt-get install zabbix-agent
and edit ''/etc/zabbix/zabbix_agentd.conf'' to configure it. In a simple passive-agent configuration you have at least to set the server address
  Server=my.server.address

Finally, restart the agent to reload configuration with
  service zabbix-agent restart
