MySQL does not start on Mac

The following error occurred connecting to MySQL:

ERROR 2002 (HY000): Can ' t connect to local MySQL server through socket '/tmp/mysql.sock ' (2)

Thought the wrong place, the cache file exists under the TMP

On the Internet to check the cause of the error, to change the file permissions

And then I found out it was because I didn't open MySQL server

To turn on MySQL server:

sudo support-files/mysql.server start

To connect to MySQL:

Cd/usr/local/mysql/bin

./mysql-u Root-p

As a beginner of programming, and novice to use Mac, if you see this post do not laugh

I'd like to use this blog to record my programming.
