mysql 无法启动Starting MySQL.The server quit without updating PID file 


InnoDB: The error means the system cannot find the path specified.

InnoDB: If you are installing InnoDB, remember that you must create

InnoDB: directories yourself, InnoDB does not create them.

InnoDB: Error: could not open single-table tablespace file ./hdd_cool/ims_wechat_dailitop.ibd

InnoDB: We do not continue the crash recovery, because the table may become

InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.

InnoDB: To fix the problem and start mysqld:

InnoDB: 1) If there is a permission problem in the file and mysqld cannot

InnoDB: open the file, you should modify the permissions.

InnoDB: 2) If the table is not needed, or you can restore it from a backup,

InnoDB: then you can remove the .ibd file, and InnoDB will do a normal

InnoDB: crash recovery and ignore that table.

InnoDB: 3) If the file system or the disk is broken, and you cannot remove

InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf

InnoDB: and force InnoDB to continue crash recovery here.

解决办法修改my.cnf里配置 如果没有这个配置添加在mysqld标签下

innodb_force_recovery = 1
