Upgrade process
To complete a successful Zabbix server upgrade on MySQL/MariaDB, you may require to set GLOBAL log_bin_trust_function_creators = 1 in MySQL if binary logging is enabled, there are no superuser privileges and log_bin_trust_function_creators = 1 is not set in MySQL configuration file.
To set the variable using the MySQL console, run:
Once the upgrade has been successfully completed, this option can be disabled:
Breaking changes
Oracle DB dropped
The support for Oracle as a backend database has been completely removed.
Frontend file directory changed during package installation
The frontend file directory has been moved from /usr/share/zabbix to /usr/share/zabbix/ui.
Note that during the upgrade the web server configuration file, if it contains custom changes (typically with Nginx), will not be automatically overwritten with the updated file containing the new paths. You will need to back up the old config file and then overwrite the old config file with the new one, for example, on RedHat based systems:
and then edit the updated configuration file (/etc/nginx/conf.d/zabbix.conf) manually to restore the old configuration.
Items turn unsupported with no pollers configured
A check for poller has been added when an item is added to configuration cache and when item type changes. This check has been added for agent, SNMP agent, HTTP agent, browser, script, JMX monitoring, ODBC monitor, and IPMI items.
If no pollers are configured, the items will turn unsupported instead of being simply ignored. This change does not affect item behavior when executed manually ("Test item") or script execution.
Loadable plugin executables relocated
When upgrading Zabbix agent 2 from packages, loadable plugin executables are moved to a new location - from /usr/sbin/zabbix-agent2-plugin to /usr/libexec/zabbix (for SLES, /usr/lib/zabbix).
After upgrading, you may need to update any previously modified plugin configuration files to reflect the new location. For example, update the MSSQL plugin Plugins.MSSQL.System.Path parameter to /usr/libexec/zabbix/zabbix-agent2-plugin-mssql.
