First - the articles are great and I look forward to more.
Second...I was having problems keeping open connections to the database (mysql ended) and read through some of the posts.
I tried the various chown directives suggested - but alas to no avail.
I don't have a var directory to change ownership of, I'm afraid. I did notice that the only files in the var directory of the compiled install were the database and log files - and the pkg installer keeps said files housed in a data folder.
I did the chown command on the data folder and lo! It worked swimmingly!
sudo chown -R mysql /usr/local/mysql/data
I guess my big question now is why? That's the frustrating part.
