Master-Master SQL DB on same VPS
We want two MySQL databases be synchronized as Master-Master when they are both on the same VPS.
We are using Plesk on Ubunto 18.04, and have two Wordpress sites…
I found this article: https://www.digitalocean.com/community/tutorials/how-to-configure-mysql-group-replication-on-ubuntu-16-04
But it is for different servers.
We can accept a solution that uses a third party service or plugin if it is not possible in a similar way like in the mentioned article.
We do not want a multisite installation and it must be on different installations.
Thank you in advance.
