MySQL启动时ERROR! The server quit without updating PID file

启动MySQL时出现错误提示：

Starting MySQL. ERROR! The server quit without updating PID file (/home/mysql/log/mysql.pid).

遇到问题，先想到看日志

# less /home/mysql/log/mysql13306_error.log

141205 15:11:51 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data
   /home/mysql/bin/mysqld: File '/home/mysql/log/binlog/binlog.index' not found (Errcode: 2)
141205 15:11:51 [ERROR] Aborting
141205 15:11:51 [Note] /home/mysql/bin/mysqld: Shutdown complete
141205 15:11:51 mysqld_safe mysqld from pid file /home/mysql/log/mysql13306.pid ended
141205 15:12:54 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data

可以看到红色部分提示很明显。找不到/home/mysql/log/binlog/binlog.index文件

如果不看日志，只是根据启动时的错误提示，就会想我一样，拼命的研究pid文件，苦寻不得解
