dpkg -i zabbix-release_6.0-4+ubuntu22.04_all.deb
apt update
Install the agent
apt install zabbix-agent
Configure the agent. I use nano but you can use the editor of your choice
nano /etc/zabbix/zabbix_agentd.conf
Search and edit
– Server=IP address or FQDN of the Zabbix Server
– ServerActive=IP address or FQDN of the Zabbix Server
– Hostname=The hostname of the server as configured on the Zabbix server
Save and exit
And enable the agent as a service
systemctl restart zabbix-agent
systemctl enable zabbix-agent
Check the installation with
systemctl status zabbix-agent
If it is active and running you are all set. Do not forget to add the host to the Zabbix Server inventory.
