So I have this setup for my wordpress.
All servers run on Centos 7 MariaDB 10.4.17 Php-FPM 7.4 PHP 7.4 NginX
Server 1, the Front Load Balancing server Server 2-3-4 the wordpress application served with NginX Server 4 MariaDB
The Nginx loadbalance setup run fine with standard info.php on each of the server 2-3-4. They switch around using the round robin.
The wordpress on its own run fine on server 2-3-4. I have to change the site URL and home URL of the wordpress in the wp-options DB to reflect the ip address of the server. So for example if I'm testing wp server 2, the site url and home url is pointed to server 2.
The second I combined all of the servers 2-3-4 under the LB with the wordpress, I got this error "The page isn’t redirecting properly". I'm not quite sure whether there's a certain settings that needs to be done in order to make the WP works under the Nginx load balancer. Any advise is how to fix the issue? Please help?
