How to Install Zabbix Agent on Debian/Ubuntu Linux

To configure the agent, first you need to find your OS versions you're working with.

cat /etc/os-release

Download the Zabbix Repository Package

To download the Zabbix agent from the most recent releases, go to the following Zabbix official download page:

https://www.zabbix.com/download 

One thing to watch out for: sometimes the wget command shown on the download page doesn't automatically update to match the exact version, distribution, or OS release you've selected. If that happens, you may need to manually adjust the repository URL. You may need to rewrite the wget repo url as shown in the next commands.

Incase if the version you are looking for doesn't appear in the download page, check out the following agent repo page and download the required release package manually by writing a wget command:

Zabbix agent repo: https://repo.zabbix.com/zabbix/7.4/release/debian/pool/main/z/zabbix-release/

For example, to download & install the Zabbix 5.0 repository package on Debian 11:

wget https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-2+debian11_all.deb

sudo dpkg -i zabbix-release_5.0-2+debian11_all.deb

sudo apt update

sudo apt install zabbix-agent

Configure the Zabbix Agent

Open the agent configuration file from the following location and update the required parameters such as the Zabbix Server IP address and Hostname

sudo vim /etc/zabbix/zabbix_agentd.conf

When you have finished configuring, restart and enable the zabbix agent process to bring up the service and to start the service during a system reboot.
