I have a dark and painful history of installing MySQL the wrong way, which has forced many late nights and ungodly amounts of frustration. It should be super easy, and sometimes it is, but sometimes it is not. And it can suck.
This post is as much a documentation of what I did so I can re-read it the next time I screw up something as it is a tutorial for you. Let’s begin.
Don’t use MacPorts, use the .dmg from the MySQL website
MacPorts will give you MySQL 5.1.48 or something like it when you install the
mysql5 port. The
mysql55 port doesn’t upgrade your
mysql5 port, it runs side by side and can be super confusing if you want to run terminal commands or change permissions on directories your forgot about when you installed
mysql5-devel doesn’t build on Mountain Lion yet. Awesome.
.dmg file will give you everything you need: installs beautifully in
/usr/local/mysql, provides a startup item installer that will fire up the
mysqld_safe launch daemon when you turn your computer on, and a Preferences pane item that will allow you to start and restart MySQL until you are blue in the face with the simple press of a button.
Your install should start like this:
- Download the
- port uninstall
mysql5-develor whatever else you have installed
- Add this to your
- Restart your computer to make sure only your new MySQL 5.5′s daemon is running (when you uninstall the MacPorts, their daemons are still running until you kill them or restart) by typing:
ps aux | grep mysql
If you see anything running from /opt, your MacPort(s) aren’t uninstalled.
After you have restarted your computer:
- Fire up Terminal and type:
mysql -u root
- Run this query:
GRANT ALL ON *.* TO 'root'@'localhost' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;(replacing ‘mypassword’ with whatever you want your root password to be)
At this point, you should have a database that works. If not, read about symlink-ing
.sock files, etc here: How to install MySQL 5.5 on Mac OS X 10.7 Lion
