CentOS Linux release 8.2.2004 (Core)
Linux vpn_svc02 4.18.0-193.19.1.el8_2.x86_64 GNU/Linux
zabbix-agent2 x86_64 5.0.4-1.el8
Steps to reproduce:
Create MySQL user for monitoring.
Open the Zabbix Agent configuration file (zabbix_agent2.conf) and set the required parameters:
Plugins.Mysql.Uri=unix:/var/lib/mysql/mysql.sock Plugins.Mysql.User=zabbix Plugins.Mysql.Password='<password>' DebugLevel=5
Start Zabbix Agent:
systemctl start zabbix-agent2.service
Zabbix Agent do not start. Attempts to start every 10 seconds. Show last Zabbix Agent log:
[Mysql] Start config validation...
log:
cannot create scheduling manager: invalid plugin Mysql configuration: Cannot assign configuration: invalid parameter Plugins.Mysql.Uri at line '<line number>': unknown parameter
Result:
Screenshot Zabbix Agent log:
P.S.
If do not use the MySQL plugin in configuration file, but add the monitoring user in macros {$MYSQL.USER} {$MYSQL.PASSWORD}, the template "Template DB MySQL by Zabbix agent 2" works.
Expected:
Launched Zabbix Agent
Fix:
In a downgraded version Zabbix Agent 2 (5.0.3), the plugin MySQL works.
