我的macOS关闭后出现问题，mysql服务器无法启动，phpMyAdmin显示此错误：
mysqli_real_connect（）:( HY000 / 2002）：没有这样的文件或目录
Apache服务器正常在MAMP上启动，但是mysql是＆＃34;死了＆＃34;。 我认为问题出在db中，但我无法解决它。

2017-04-09 01:33:41 7fffd6a0a3c0 InnoDB: Operating system error number 2 in a file operation.
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 ./wordpress/wp_term_taxonomy.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.

答案 0 :(得分：1)
我遇到了同样的问题，你只需要将ib_logfile0和ib_logfile1重命名为ib_logfile_0和ib_logfile_1。然后你的问题就会解决。
