HOW TO INSTALL ZABBIX AGENT ON CENTOS 7 AND UBUNTU 18.04

James May 27, 2019 3 Comments

In our previous post, we covered the installation of Zabbix on Ubuntu server
18.04. In this guide, we will go a step further and install the Zabbix agent on
both CentOS 7 and Ubuntu 18.04. Zabbix agent collects metric data such as CPU
utilization, CPU load, memory and disk utilization, and ships it to the Zabbix
server for visualization. We will tackle the installation of the Zabbix agent in
each of the Linux distributions.


PREREQUISITES

To get started, ensure that you have instances of Ubuntu 18.04 and CentOS 7 with
SSH access. You can readily deploy Managed VPS Cloud servers from CloudCone at
just $3.71 for this exercise.

 


INSTALL ZABBIX AGENT ON UBUNTU 18.04

To install Zabbix agent on Bionic beaver, (Ubuntu 18.04) follow the steps below


STEP 1: ADD ZABBIX REPOSITORY

Zabbix-agent is not present in Ubuntu 18.04’s base repository by default. To add
it, first download the Zabbix Debian file using wget command:

wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-2+bionic_all.deb



 

Append the repository using the dpkg command

dpkg -i zabbix-release_4.0-2+bionic_all.deb



Next, update the system for the changes to take effect.

sudo apt update



 


STEP 2: INSTALL ZABBIX AGENT

Upon successful installation of Zabbix repository, install Zabbix on Ubuntu
18.04 using the command

# sudo apt install zabbix-agent



 


STEP 3: CONFIGURE ZABBIX

Once Zabbix agent is successfully installed, make a few modifications in
Zabbix’s configuration file as shown

vim /etc/zabbix/zabbix_agentd.conf

Make the following modification to these attributes

Server=IP address of Zabbix Server

Hostname=Hostname of client PC

Once done, save the changes and exit the text editor.

 


STEP 4: RESTART AND ENABLE ZABBIX AGENT

To effect the changes made, restart Zabbix agent an enable it upon boot-up

systemctl restart zabbix-agent

systemctl enable zabbix-agent



Finally, verify is the zabbix-agent service is running as expected

systemctl status zabbix-agent



 


INSTALL ZABBIX AGENT ON CENTOS 7 / RHEL 7

Let’s now see how we can install Zabbix agent on CentOS 7


STEP 1: ADD ZABBIX REPOSITORY

To add Zabbix repository run

rpm -ivh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm



 


STEP 2: INSTALL  ZABBIX AGENT

With the successful installation of Zabbix repository, now install Zabbix-agent

yum install -y zabbix-agent



 


STEP 3: CONFIGURE ZABBIX

Once again, as in Ubuntu 18.04,  make the changes to Server and Hostname
attributes in Zabbix’s configuration file as shown

vim /etc/zabbix/zabbix_agentd.conf

Make the following modification to these attributes

Server=IP address of Zabbix Server

Hostname=Hostname of client PC

Once done, save the changes and exit the text editor.

 


STEP 4: RESTART AND ENABLE ZABBIX AGENT

Finally, To effect the changes made to the configuration files, restart Zabbix
agent an enable it upon boot-up

systemctl restart zabbix-agent

systemctl enable zabbix-agent



To verify that Zabbix agent is runnig=ng as expected, execute the command

systemctl status zabbix-agent



 

Wonderful! We have successfully installed Zabbix agent to both Ubuntu 18.04 and
CentOS 7 and verified that the Zabbix agent is running just fine. In our next
tutorial, we shall head out to the Zabbix dashboard and add the two Linux
systems for data visualization and analysis.
