OVH Separate DB Server on OVH

You'd need to create all the databases on the db server and manually create all user grant permissions for remote web server to connect to remote db server. Centmin Mod addons/mysqladmin_shell.sh only creates mysql users for local mysql server and not remote.

Yes i usually recommend centmin mod install just stop php-fpm and nginx services on db server. That way if your web server dies, you can immediate start php-fpm and nginx servers on db server and have everything moved from web server to db much quicker.

These days you aren't going to get that much better performance splitting mysql to separate server unless you're overwhelming existing web+db server and there's contention in resource usage for nginx, php-fpm and mysql. In fact response time will be slower splitting db services up to a certain point depending on mysql user concurrency work loads you have. Unless you're constantly pushing 300-500+ concurrent mysql connections (not same as forum users, php-fpm or nginx concurrent users) and mysql query response time is negatively impacted at high mysql concurrent user loads, splitting to separate db server isn't really needed. Monitoring server resource usage statistics is key to determining when db remote server offloading is needed.

 

FYI, OVH vrack isn't supported by OVH gaming servers AFAIK

 

Yup gaming motherboards don't have the support.
