Upgrading MySQL on Mac OS X Server

Question

I'm attempting (and failing) to upgrade MySQL on Mac OS X Server (Leopard) and running into trouble. Though the OS X Server docs say it's "normal" to have multiple versions of MySQL on your machine they don't go into any detail of how to "manage" them.

I have built and installed a newer version (5.1.40) than the original that Apple bundled (5.0.x).

Server Admin seems to manage only the initial (5.0.x) installation in /usr/bin

So I've STOPPED that version in Server Admin but can't get the new one (in /usr/local/mysql) to work.

Ideally I'd like to point the new version of mysql at the old database files in /var/mysql but not sure how...

Edit: Looks like my new MySQL is active (for some users anyway) but it's pointing to a different data file. It's pointing to /usr/local/mysql/data and I want it to point to /var/mysql

Admin user can connect but others get: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2). I'm assuming because this new database doesn't have those users enabled yet?!?! though I'd think I could still $ mysql -u root -p to it?!?

Anyone know how to manage this?

Answer 1

Well, I renamed the new MySQL's data directory to data.backup and then I created a symlink from where the new MySQL's data folder was to /var/mysql (where the old data file is) and so far so good... New version of MySQL is running and using the existing data file for its databases...

I'm not sure how to resolve your issue, but maybe you could trying using Homebrew or another OS X package manager to handle your software.

Will make upgrading in future a breeze.

EDIT: Sorry, just realized you are using OS X SERVER, I'm not familiar with it or if you should be using Homebrew on it.
