Click the triangle next to the “More Options” label on the connection string an change the “Connect Using Socket” field to the path of your socket file.

To determine where your socket file is, type:

netstat -ln | grep mysql

sudo port uninstall mysql5-server
sudo port uninstall mysql5

sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*

edit /etc/hostconfig and remove the line MYSQLCOM=-YES-

rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

Thanks to Rob Allen.

Install MySQL5

sudo port install mysql5
sudo port install mysql5-server 
sudo -u mysql mysql_install_db5

Secure MySQL5

To secure your MySQL5 installation, you can either change the password manually like so:

/opt/local/lib/mysql5/bin/mysqladmin -u root password {new-password}

or on a production system, you can run the secure script and not only change the password, but remove anonymous access and prevent remote root login.

/opt/local/lib/mysql5/bin/mysql_secure_installation

To start the MySQL daemon, type:

sudo /opt/local/lib/mysql5/bin/mysqld_safe &

or to make sure MySQL5 is launched at startup every time:

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

Create a symbolic link

sudo ln -s /opt/local/bin/mysql5 /opt/local/bin/mysql

Test the installation

mysql -u root -p

It should prompt you for a password and you should see the “mysql>” prompt

sp_change_users_login ‘report’

To correct it, use the same stored procedure with a different command.

sp_change_users_login ‘update_one’, ‘{username}’, ‘{login}’

This will make sure that your username and login have the same SID.
