Question

I\'ve just tried installing MySQL using homebrew (on Mac OS X 10.6), but I\'ve run across an issue at the first hurdle. When trying to manually start the server (mysql.serve

Answer 1

I ran into the same issue while trying to install MySQL 5.5.15 in Lion using homebrew and resolved the issue with:

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

and creating a the file ~/my.cnf

with the content:

 [mysqld]
   basedir=/usr/local/Cellar/mysql/5.5.15
   datadir=/usr/local/var/mysql

basedir - should be your current MySQL instalation dir datadir - should be the location of MySQL data

You can figure out that too location by watching the make command during the "brew install mysql" searching for something like this:

-DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/mysql/5.5.15 -DMYSQL_DATADIR=/usr/local/var/mysql -DINSTALL_MANDIR=/usr/local/Cellar/mysql

Where DCMAKE_INSTALL_PREFIX = basedir and DMYSQL_DATADIR = datadir
