Setting up a fresh OSX rails install

While setting up a fresh rails install on a basically virgin system, I stumbled across this web site which goes over exactly that. So, instead of having to figure this all out for myself (again) I could simply follow the instructions of another.

All was not pain free however (why is the process never pain free?). When trying to start mysql via launchctl, mysqld would not start. In fact it didn’t seem to do anything! I could see the mysql.server start script being called but then it would just sit there.

Since that route failed me, I then tried the more direct route of starting via /opt/local/lib/mysql5/bin/mysqld. This seemed to start the server but it would then immediately stop. Checking the logs, I found this:

061224 23:09:52  mysqld started

Looking up the mysql/host.frm complaint with google led me to this thread on linuxquestions. Bullet point #5 of “Butt-Ugly“‘s response solved my problem. Looks like perhaps darwinports or myself had created this database with the root user instead of the mysql user causing mysqld to have permissions problems when trying trying to read files it needed.

Removing the files in that directory followed by a restart of the server fixed the problem and I was on my way to mysql bliss.
