Written by Rahul K.

Zabbix Agent is required to install on all remote systems needs to be monitor through Zabbix server. The Zabbix Agent collects resource utilization data and applications data on client system and provide such information to Zabbix server on their requests.

There are two types of checks between Zabbix Server and Client.

Passive Check : Zabbix Agent sent data to server on their request.
Active Check : Zabbix Agent sends data periodically to Server.

After installing zabbix server on your server, Now we are moving to install agent on remote system’s. This article will help you to install zabbix agent on CentOS/RHEL 7/6/5 systems. After completing this step go to next article add Host in Zabbix Server.

Installing Zabbix Agent

Follow the below instructions to install Zabbix Agent on CentOS, RHEL 7/6/5 systems.

Step 1 – Add Required Repository

Before installing Zabbix Agent first configure zabbix yum repository using following commands as per your required version and operating system.

CentOS/RHEL 7:
# rpm -Uvh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

CentOS/RHEL 6:
# rpm -Uvh http://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm

CentOS/RHEL 5:
# rpm -Uvh http://repo.zabbix.com/zabbix/3.0/rhel/5/x86_64/zabbix-release-3.0-1.el5.noarch.rpm

Step 2 – Install Zabbix Agent

After installing yum repository packages in our system. Now use following command to install Zabbix agent on your Linux system.

# yum install zabbix zabbix-agent

Step 3 – Edit Zabbix Agent Configuration

As zabbix agent has been successfully installed on our remote system. Now we just need to configure zabbix agent by adding zabbix server ip in its configuration file /etc/zabbix/zabbix_agentd.conf

#Server=[zabbix server ip]
#Hostname=[ Hostname of client system ]

Server=192.168.1.11
Hostname=Server1

Step 4 – Restarting Zabbix Agent

After adding zabbix server ip in configuration file, now restart agent service using below command.

# /etc/init.d/zabbix-agent restart

To start and stop zabbix-agent service anytime use following commands.

# /etc/init.d/zabbix-agent start
# /etc/init.d/zabbix-agent stop

At REHL 7/CentOS 7, /etc/init.d/zabbix-agent start is old dated and not available anymore

use
systemctl restart zabbix-agent

and to auto-start it after a reboot
systemctl enable zabbix-agent

If you use incoming connections open the firewall…

  You can use zabbix agent in active mode so you do not need open the port. You have to give the zabbix server ip on filed ServerActive=
  On that case, you have to make sure that on zabbix server side, you have to open the 10051 port.
  
  Hope that help.

Hi,

Is it possible to install Zabbix Agent as non root user?
e.g. install as zabbix.

I don’t have access to root on many of my servers and it would be hard to get the SA to approve that.

Thanks,
Alex

Kudos to you and many thanks.

  Hm…
  Sometimes it happens that mysql write/read speed is just not fast enough so it can’t be writen inside mysql db. This can cause slow response time of zabbix! You can try to tune mysql ,tune i/o operations on server or add more hardware resourses!
