Mysql Master-SlaveMySQL Master-Slave replication is natively supported by MySQL. However its configuration is not so simple. For each slave added as a replica, a few configuration steps must be done on both the master and itself.

So if you want to install a master instance on a machine or VM, and then install 5 other instances as slaves on other hosts, you will be doing quite a lot of back-and-forth configuration. I couldn’t find any way of configuring the replication automatically on the web, so I decided to create my own bash script to do it.
