+## mysql
+
+```
+Set up databases to run AS YOUR USER ACCOUNT with:
+    unset TMPDIR
+    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
+--> mysql 2
+
+To set up base tables in another folder, or use a different user to run
+mysqld, view the help for mysqld_install_db:
+    mysql_install_db --help
+
+and view the MySQL documentation:
+  * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
+  * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html
+
+To run as, for instance, user "mysql", you may need to `sudo`:
+    sudo mysql_install_db ...options...
+
+Start mysqld manually with:
+    mysql.server start
+
+    Note: if this fails, you probably forgot to run the first two steps up above
+
+A "/etc/my.cnf" from another install may interfere with a Homebrew-built
+server starting up correctly.
+
+To connect:
+    mysql -uroot
+
+To launch on startup:
+* if this is your first install:
+    mkdir -p ~/Library/LaunchAgents
+    cp /usr/local/Cellar/mysql/5.5.25/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/
+    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
+
+* if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded:
+    launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
+    cp /usr/local/Cellar/mysql/5.5.25/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/
+    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
+
+You may also need to edit the plist to use the correct "UserName".
+
+==> Summary
+/usr/local/Cellar/mysql/5.5.25: 6382 files, 222M, built in 7.5 minutes
+```
+
+## mysql 2
+
+```
+To start mysqld at boot time you have to copy
+support-files/mysql.server to the right place for your system
+
+PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
+To do so, start the server, then issue the following commands:
+
+/usr/local/Cellar/mysql/5.5.25/bin/mysqladmin -u root password 'new-password'
+/usr/local/Cellar/mysql/5.5.25/bin/mysqladmin -u root -h mba-2.local password 'new-password'
+
+Alternatively you can run:
+/usr/local/Cellar/mysql/5.5.25/bin/mysql_secure_installation
+
+which will also give you the option of removing the test
+databases and anonymous user created by default.  This is
+strongly recommended for production servers.
+
+See the manual for more instructions.
+
+You can start the MySQL daemon with:
+cd /usr/local/Cellar/mysql/5.5.25 ; /usr/local/Cellar/mysql/5.5.25/bin/mysqld_safe &
+
+You can test the MySQL daemon with mysql-test-run.pl
+cd /usr/local/Cellar/mysql/5.5.25/mysql-test ; perl mysql-test-run.pl
+
+Please report any problems with the /usr/local/Cellar/mysql/5.5.25/scripts/mysqlbug script!
