MyEnv Installation Guide

This article will cover the installation of MyEnv, the MySQL and MariaDB environment of FromDual.

Why MyEnv?

MyEnv is a program to run multiple MySQL, MariaDB, Percona Server or Galera Cluster database instances on ONE server with ease. You can even run multiple database instances with different binary versions.

MyEnv for MySQL Multi-Database set-ups

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 more comfortable than mysqld_multi and provides more functionality.
