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-serverIf upgrading the proxy, stop proxy too.
# systemctl stop zabbix-proxy2 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.rpm5 Upgrade Zabbix components
To upgrade Zabbix components you may run something like:
# yum upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agentIf 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-agentMinor upgrade procedure
