MIM - Mini MySQL/MariaDB Instance Manager


mim is a single bash script ('my') to build and manage local installations of MySQL or MariaDB for development and testing.


  • Put the 'my' bash script into a directory in your path, I tend to use ~/bin
  • Create a directory to contain the binary tar.gz files for you platform. I.e. ~/mim-binaries
  • Create a directory to contain the database installations. I.e. ~/mim-databases
  • Export these directories as a the relevant variable in your bash profile:
export MIMBINARIES=~/mim-binaries
export MIMHOME=~/mim-databases
  • With 'my' now in your path, run 'my setup', this will create directories in $MIMHOME
  • Copy the configs from example_configs to $MIMHOME/templates

Create your first instance

  • Put a binary package of MySQL or MariaDB in $MIMBINARIES:
$ cp ~/Downloads/mariadb-5.5.35-linux-x86_64.tar.gz $MIMBINARIES/
$ cp ~/Downloads/mysql-5.5.35-linux-x86_64.tar.gz $MIMBINARIES/
  • Create a config, we will call it master1 to run on port 3000, select options such as config and version as appropiate:
$ my build master1 3000
  • If the above went smoothly, then you have installed MIM correctly, now install the instance:
$ my install master1
  • Start the instance:
$ my start master1
  • Print aliases for your configured instances, to easily access them:
$ my aliases
  • Generate a PATH and LD_LIBRARY_PATH variables for the desired instance:
$ my client master1


  • MySQL 5.6+ and MariaDB 10+ GTID management for testing failover.
  • Client path switching
  • Library path switching for building C/C++ projects like ODBC connectors.
  • ... better documentation.
