mysql无法启动

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

查看data下的错误信息显示

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MysqLd标签

innodb_force_recovery = 1
