protect"/ tmp/mysql.sock" is not deleted

If you have this problem, virtually anyone can delete the MySQL communication socket "/tmp/mysql.sock", on most versions of Unix, you can do this by setting sticky (t) bit to protect your "/tmp" filesystem. Log in as root and do the following:

shell> chmod +t /tmp

This will protect your "/tmp" filesystem so that files can only be deleted by their owner or superuser (root).

You can do ls -ld /tmp to check if the sticky bit is set, if the last permit bit is t, the bit is set.
