MySQL 4 macports setup
If you did not choose the server variant you may add a mysql user and you will need to change the ownership to that user:
sudo chown mysql /opt/local/var/db/mysql sudo chown mysql /opt/local/var/run/mysqld sudo chown mysql /opt/local/var/log/mysql
You might want to run
sudo -u mysql mysql_install_db
You have to symlink mysql to the location on osx
first find out where mysql has put the socket:
mysql_config --socket
Next symlink /tmp/mysql.sock to the right location of the socket
sudo ln -s path-of-mysql.sock-from-above /tmp/mysql.sock
Start MySQL
sudo /opt/local/share/mysql/mysql.server start
Stop MySQL
sudo /opt/local/share/mysql/mysql.server stop
