In our current project the customer wants to install and run multiple MySQL Enterprise Server 5.7 Instances on the same machine (yes, I know about virtualization (we run on kvm), containers, Docker, etc.). He wants to use Redhat Enterprise Linux (RHEL) 7 which brings the additional challenge of SystemD. So mysqld_multi is NOT an option any more.

We studied the MySQL documentation about the topic: Configuring Multiple MySQL Instances Using systemd. But to be honest: It was not really clear to me how to do …

We have been asked several times by MySQL users about how to install multiple MySQL instances on a single host.
Typically, this is required when testing different MySQL versions or MySQL servers (MySQL server, Percona server and MariaDB server) while no available resources are available.
Sometimes, it is even required to install multiple MySQL instances on a single production server.

This week I showed one of my customers our MyEnv. He was very interested in it and suggested to make it known in public. In fact MyEnv is available for download already several years…

What is MyEnv?

MyEnv is a tool to run several MySQL or MariaDB database instances on ONE host. You can even run multiple database instances with different binary versions. We call this multi-instance set-ups.
