Install Zabbix 4.4 Server on CentOS 8

Install Zabbix 4.4 Server on CentOS 8

Zabbix is a free and open-source networking monitoring software. With Zabbix, we can monitor networks, servers, virtual machines and cloud services. Zabbix software is developed and maintained by Zabbix LLC and distibuted under GPLv2 license.

In this article, we are installing Zabbix 4.4 Server on CentOS 8.

 

This Article Provides:

     

    Zabbix 4.4 Features:

    Some of the distinct features of Zabbix are:

    • Distributed monitoring with centralized web administration.
    • Auto-discovery of servers and network devices and interfaces
    • High performance, high capacity (able to monitor hundreds of thousands of devices).
    • SLA, and ITIL KPI metrics on reporting.
    • Native high performance agents (client software for Linux, Solaris, HP-UX, AIX, FreeBSD, OpenBSD, OS X, Tru64/OSF1, Windows 2000, Windows Server 2003, Windows XP, Windows Vista, Windows Server 2008, Windows 7)

     

    Zabbix 4.4 Server Prerequisites:

    Zabbix 4.4 server requires following software packages.

    • Database Backend  - MySQL (5.0.3 - 8.0.x)
    • Web Server - Apache HTTP Server (1.3.12 or later) 
    • PHP Support (5.4 or later)

    Hardware requirements may vary based on the number of devices that you want to monitor via Zabbix 4.4 server. For complete information about Zabbix 4.4 requirments, you can visit Zabbix 4.4 documentation.

     

    Environment Specification:

    We have provisioned a CentOS 8 virtual machine for this tutorial.

    • CPU - 3.4 Ghz (2 cores)
    • Memory - 2 GB
    • Storage - 20 GB
    • Operating System - CentOS 8.0
    • Hostname - zabbix-01.recipes.com
    • IP Address - 192.168.116.207 /24

     

    Installing LAMP stack on CentOS 8:

    Connect to zabbix-01.recipes.com using ssh as root user.

    Zabbix is PHP based software thus requires a PHP application server to run.

    Therefore, we are installing Apache HTTP Server, MySQL Database Server and PHP support using a single dnf command.

    [root@zabbix-01 ~]# dnf install -y httpd mysql-server php php-mysqlnd php-mbstring php-pdo php-gd ...

    Enable and start Apache service.

    [root@zabbix-01 ~]# systemctl enable --now httpd.service Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service â /usr/lib/systemd/system/httpd.service.

    Allow Apache service in CentOS 8 firewall.

    [root@zabbix-01 ~]# firewall-cmd --permanent --add-service=http ; firewall-cmd --reload success success

    Enable and start MySQL database service.

    [root@zabbix-01 ~]# systemctl enable --now mysqld.service Created symlink /etc/systemd/system/multi-user.target.wants/mysqld.service â /usr/lib/systemd/system/mysqld.service.

    Configure MySQL database instance as follows.

    [root@zabbix-01 ~]# mysql_secure_installation Securing the MySQL server deployment. Connecting to MySQL using a blank password. VALIDATE PASSWORD COMPONENT can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD component? Press y|Y for Yes, any other key for No: y There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2 Please set the password for root here. New password: Re-enter new password: Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y Success. All done!

    Edit PHP configurations to customize it according to our environment.

    [root@zabbix-01 ~]# vi /etc/php.ini

    Uncomment and set following directive.

    date.timezone = Asia/Karachi

     

    Installing Zabbix Yum Repository on CentOS 8:

    As described in Zabbix 4.4 documentation, we can install Zabbix yum repository in our CentOS 8 server as follows.

    We have setup the Zabbix yum repository, therefore, we can easily install Zabbix packages using dnf command. Here, we are installing Zabbix with MySQL database support.

      1. Try to start the Zabbix service and checkout the error.
        For further guidance, contact me at our Facebook Page along with the screenshot of the error.

      1. This is caused due to the IPv6 configuration in CentOS / RHEL 8. If you are not using IPv6 then you should disable it using following command.

        # sysctl -w net.ipv6.conf.all.disable_ipv6=1

        Now execute your dnf command again.

      1. It means you don't have any policy violations. Skip this step and continue.
