120515 18:13:01 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

• Regarding this error, I assume that you have specified a datadir in my.cnf. If you are using a non-default data directory for MySQL, you need to move folders mysql and performance_schema (whichever exists) to the data directory specified in my.cnf. You can find these folders in mysql directory.

In MySQL 5.5+ the --skip-locking option is removed. Use --skip-external-locking instead. Refer to MySQL documentation --> http://dev.mysql.com/doc/refman/5.5/en/mysql-nutshell.html Quote: "The --enable-locking and --skip-locking server options (use --external-locking and --skip-external-locking)."

I had the same problem after updating to OS X Mavericks.

Starting MySQL . ERROR! The server quit without updating PID file

Like Redrick and AndPy mentioned I also had to rename (actually I deleted the file) the error file located in $ cd /usr/local/var/mysql. My error file was called localhost.err. After removing the file with $ rm localhost.err I could finally start MySQL again with $ mysql.server start.

Give this a whirl..

1. Navigate to the problem's parent directory cd YOURPATH/usr/local/mysql
2. rm -rf *.local.err (deletes file)
3. touch YOURUSERNAME.local.pid (generates new *.local.pid file the error thrown was complaining about)
4. cd back into your project and restart mysql using mysql.server start

My answer is very similar to others, but slightly different and this applies mostly to a bitnami mamp stack. The fix for me was:

sudo chown -R mysql mysql/

The mysql/ directory is the one located in Applications/<mampstack-version>/

The above sets the mysql to be the owner of the mysql directory recursively into the other directories.
