In this installation, I will use password rootDBpass as root password and zabbixDBpassas Zabbix password for DB. Consider changing your password for security reasons.
b. Configure web frontend
Connect to your newly installed Zabbix frontend using URL “http://server_ip_or_dns_name/zabbix” to initiate the Zabbix installation wizard. In my case, that URL would be “http://192.168.1.161/zabbix” because I have installed Zabbix on the server with IP address 192.168.1.161 (you can find the IP address of your server by typing “ip a” command in the terminal). NOTE: If you get an error saying that the minimum required version of php is 7.4, upgrade your PHP using these commands: sudo dnf -y i...

Create file “10_my_tweaks.cnf" with “nano /etc/my.cnf.d/10_my_tweaks.cnf” and paste this configuration: Save and exit the file (ctrl+x, followed by y and enter) and set the correct file permission: Two things to remember! Configuration parameter max_connectionsmust be larger than the total number of all Zabbix proxy processes plus 150. You can use the command below to automatically check the number of Zabbix processes and add 150 to that number: The second most important parameter is innodb_b...
