Today I performed a brew update. I noticed that MariaDB now exists as stable (5.5.30) and devel (10.0.2). Brew formulas also exist for MySQL (5.6.10) and Percona Server (5.5.30-30.2) now. 10.0.3 is around the corner but I wanted to run 10.0.2 now. This is how I did it:
brew unlink mariadb brew install --devel mariadb
It’s that simple!
