# firewall-cmd -permanent –zone=mysql_replication_access -add-rich-rule='rule family="ipv4" source address="X.X.X.X" forward-port to-addr="Y.Y.Y. So i think something like the following firewall rule, is most probably needed.
# firewall-cmd -zone=mysql_replication_access -add-port=3306/tcp -permanentīut in your case you also need port forwarding which is created by your firewall rules for your specific zone as listed above. # firewall-cmd -zone=mysql_replication_access -add-source=Y.Y.Y.Y/Y -permanent // Y.Y.Y.Y/Y client server ip address or range

(You could try this first.) # firewall-cmd -new-zone=mysql_replication_access -permanent To allow port 3306 in your firewall rules you would need something like this. Grant replication permission mysql > GRANT REPLICATION SLAVE ON *.* TO IDENTIFIED BY 'mysecurepass' Or you could try the following changes/additions:Ĭreate a repl_user like this: mysql> CREATE USER // where X.X.X.x is the external ip of the master server To create a SSH tunnel use the following command.

It points out the steps needed for the replication, how to set up users on both servers, configure MySQL and more. Here is a nice-to-read guide on how to achieve that.
