About MySQL Startup error problem, Memo

Do a data backup today after the operation, found that the database boot does not start, check the error log prompt:

Starting MySQL ...... error! The server quit without updating PID file (/data/mysql/mysql.master.com.pid).

The first idea is to view the log file (beginning with the/ETC/MY.CNF definition):

Found such a sentence:

/etc/mysql/bin/mysqld:file './mysql-bin.index ' not Found (errcode:13)

Check that the prompt should be the directory permission has a problem and then execute:

Chown Mysql.mysql-r/data

And then reboot to find the success.

There is also a flushing situation when deleting the Myslq-bin.index file, specifically what the operation has forgotten. If you can't, try it.
