This is very important for your zabbix server upgrade to new version. So I want to show how to upgrade zabbix server 4.0 to 4.4 on your centos 8 server. So follow my step by step configuration for upgrade zabbix server 4.4 version.

★ Install Zabbix Agent Into Windows

★ How To See IP Address On Windows

My Zabbix server info details :

Service : zabbix_server (Zabbix) 4.0.13
php : 7.2
Database : 10.3.11-MariaDB
Zabbix server IP : 10.66.10.50

You can check your zabbix server, php & mariadb version using below command.

[root@Zabbix-Server ~]# zabbix_server -V
[root@Zabbix-Server ~]# php -v
[root@Zabbix-Server ~]# mysql -V

If your Zabbix server, PHP & maridb version is low so first update this then use below steps.

Step #01: Now start for upgrade Zabbix server.

[root@Zabbix-Server ~]# service zabbix-server stop
[root@Zabbix-Server ~]# mkdir zabbix
[root@Zabbix-Server ~]# mysqldump -u root -p zabbixdb > zabbix/zabbixdb.sql
[root@Zabbix-Server ~]# cp /etc/zabbix/zabbix_server.conf zabbix
[root@Zabbix-Server ~]# cp /etc/httpd/conf.d/zabbix.conf zabbix
[root@Zabbix-Server ~]# cp /etc/zabbix/zabbix_agentd.conf zabbix

This is only for backup if any problem so I am recover from backup. 🙂

Step #02: Download latest Zabbix 4.4 repo from official link & then upgrade.

[root@Zabbix-Server ~]# rpm -Uvh http://repo.zabbix.com/zabbix/4.4/rhel/8/x86_64/zabbix-release-4.4-1.el8.noarch.rpm
[root@Zabbix-Server ~]# yum clean all
[root@Zabbix-Server ~]# yum update
[root@Zabbix-Server ~]# service zabbix-server status
[root@Zabbix-Server ~]# service zabbix-server start

Now go to your browser and reload login page & see login as a guest user. So you logout and then again login your Admin account.
