Overview

Make sure to read general information about upgrading first.

Upgrade procedure

1 Stop Zabbix processes

Stop Zabbix server to make sure that no new data is inserted into database.

# systemctl stop zabbix-server

If upgrading the proxy, stop proxy too.

# systemctl stop zabbix-proxy

2 Back up the existing Zabbix database

This is a very important step. Make sure that you have a backup of your database. It will help if the upgrade procedure fails (lack of disk space, power off, any unexpected problem).

3 Back up configuration files, PHP files and Zabbix binaries

Make a backup copy of Zabbix binaries, configuration files and the PHP file directory.

Configuration files:

# mkdir /opt/zabbix-backup/
       # cp /etc/zabbix/zabbix_server.conf /opt/zabbix-backup/
       # cp /etc/httpd/conf.d/zabbix.conf  /opt/zabbix-backup/

PHP files and Zabbix binaries:

# cp -R /usr/share/zabbix/ /opt/zabbix-backup/
       # cp -R /usr/share/doc/zabbix-* /opt/zabbix-backup/

4 Update repository configuration package

To proceed with the upgrade your current repository package has to be updated.

# rpm -Uvh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

5 Upgrade Zabbix components

To upgrade Zabbix components you may run something like:

# yum upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agent

If using PostgreSQL, substitute mysql with pgsql in the command. If upgrading the proxy, substitute server with proxy in the command.

6 Review component configuration parameters

There are no mandatory changes in this version to component parameters. For new optional agent parameters, see the What's new section.

7 Start Zabbix processes

Start the updated Zabbix components.

# systemctl start zabbix-server
       # systemctl start zabbix-proxy
       # systemctl start zabbix-agent

Minor upgrade procedure

Zabbix minor version upgrade is an easy procedure. It means for example upgrading from Zabbix 3.2.0 to 3.2.x. To execute Zabbix minor version upgrade it is required to run:

# yum update zabbix-*

To execute zabbix agent minor version upgrade run:

# yum update zabbix-agent

To execute zabbix server minor version upgrade run:
