In this tutorial for upgrade zabbix system from version 5.0 to 5.4. ZABBIX is an open source network monitoring tools. So I will try to provide zabbix server upgrade using testing lab.

###############################
Operating system: ubuntu 20.04
Zabbix version	: 5.0.16
Mysql version	: 8
Php version	: 7.4
###############################

Step #01: Check all version using below command.

root@ubuntu20:~#: lsb_release -a && ip r
root@ubuntu20:~#: zabbix_server -V
root@ubuntu20:~#: mysql -V
root@ubuntu20:~#: php -v
root@ubuntu20:~#: systemctl stop zabbix-server

Step #02: Create backup zabbix server.

root@ubuntu20:~#: mkdir backup
root@ubuntu20:~#: cp /etc/zabbix/zabbix_server.conf /root/backup
root@ubuntu20:~#: cp /etc/zabbix/zabbix_agentd.conf /root/backup
root@ubuntu20:~#: cp /etc/zabbix/web/zabbix.conf.php /root/backup
root@ubuntu20:~#: mysqldump -u root -p zabbix > /root/backup/zabbix.sql

Step #03: Create upgrade using below command.

root@ubuntu20:~#: wget wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1%2Bubuntu20.04_all.deb
root@ubuntu20:~#: dpkg -i zabbix-release_5.4-1+ubuntu20.04_all.deb
root@ubuntu20:~#: apt-get update
root@ubuntu20:~#: apt-get install --only-upgrade zabbix-server-mysql zabbix-agent zabbix-frontend-php
root@ubuntu20:~#: apt -y autoremove
root@ubuntu20:~#: tail -f /var/log/zabbix/zabbix_server.log

Step #04: Move old config file

root@ubuntu20:~#: cp /root/backup/zabbix_server.conf /etc/zabbix/
root@ubuntu20:~#: cp /root/backup/zabbix_agentd.conf /etc/zabbix/
root@ubuntu20:~#: cp /root/backup/zabbix.conf.php /etc/zabbix/web/

Then restart below service.

root@ubuntu20:~#: systemctl restart zabbix-server zabbix-agent nginx php7.4-fpm
root@ubuntu20:~#: systemctl enable zabbix-server zabbix-agent nginx php7.4-fpm

Check log for upgrade status.

root@ubuntu20:~#: tail -f /var/log/zabbix/zabbix_server.log
