How to config for multi VPS

Centmin Mod is provide as is, so short of scripted related bugs or issues, any further optimisation to the web stack components - nginx, php-fpm, mariadb mysql, csf firewall etc or web app specific configurations are left to the Centmin Mod user to deal with. So I do not provide any free support for such HA setups.

However, Centmin Mod users are free to help each other out and ask questions or give answers on this community forum. My hopes are that this community forum evolves so that more veteran long time Centmin Mod users help new Centmin Mod users out

Centmin Mod's Nginx has all the nginx modules it requires for you to configure nginx reverse proxy, nginx based load balancing and proxy caching (with exception of the shared file system you'd need i.e. NFS, GlusterFS and any mysql database cluster/replication). You just have to configure it yourself

For nginx reverse proxy & load balancing read the documentation, tutorial and guides below
