How To Upgrade Zabbix Server From 3.2.6 To 3.4.1

Zabbix is very much needed to monitor all your servers. Both updates have been released a few days ago. So how do you make a lot of updates on your server? I have many post on Zabbix features. Such as

★ Send Mail Notification From Zabbix Server Using Gmail

★ How To Add Windows Host In Zabbix Server

Now very important think how can I upgrade my Zabbix server 3.2.6 to 3.4.1

Step #01: First you can stop your Zabbix server.

root@zabbix-server:~# service zabbix-server stop

Step #02: Backup your Zabbix databases for risk free. But I can’t needed.

root@zabbix-server:~# mysqldump -u root -p zabbix > zabbix.sql

Step #03: Add Zabbix source list for update repository.

root@zabbix-server:~# vim /etc/apt/source.list.d/zabbix.list

Insert below two lines

deb http://repo.zabbix.com/zabbix/3.4/ubuntu trusty main
deb-src http://repo.zabbix.com/zabbix/3.4/ubuntu trusty main

Step #04: Now download Zabbix released deb package via wget command.

root@zabbix-server:~# wget http://repo.zabbix.com/zabbix/3.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.4-1+trusty_all.deb

Step #05: Install downloaded packages via dpkg command.

root@zabbix-server:~# dpkg -i zabbix-release_3.4-1+trusty_all.deb

Now update your Zabbix server command

root@zabbix-server:~# apt-get update

Step #06: Then Zabbix main update command

root@zabbix-server:~# apt-get install --only-upgrade zabbix-server-mysql zabbix-agent zabbix-frontend-php

Press N 2 times for zabbix agent, apache.conf and server config file overwrite. Wait for few times when update completed.
Very important issue Zabbix server config file contains DB name, DB password and DB server name on localhost or 127.0.0.1 

Step #07: Open Zabbix server config file check this issue.

root@zabbix-server:~# vim /etc/zabbix/zabbix_server.conf

Ensure that all lines include into server config file

DBName=zabbix
DBUser=zabbix
DBPassword=passw0rd

Step #08: All is ok then finally Zabbix server start.

root@zabbix-server:~# service zabbix-server start

Now goto your browser and type http://server-ip/zabbix/

You can see some databases error. But don’t worry wait for few minutes then reload your browser.
