MAMP PRO mysql无法启动

mac上可能勾选了软件自动更新，然后MAMP PRO 升级了。

升级了之后，mysql启动就出问题了，看报错日志：

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.
 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended

　很迷茫，百度搜了一圈，没什么好的方案。转google，终于看到一个：

经测试，执行以下命名，删除这些东西，就可以重启mysql了

$ rm /Library/Application\ Support/appsolute/MAMP\ PRO/db/mysql56/ib_logfile0
$ rm /Library/Application\ Support/appsolute/MAMP\ PRO/db/mysql56/ib_logfile1
$ rm /Library/Application\ Support/appsolute/MAMP\ PRO/db/mysql56/ibdata1

如果你现在链接数据库没问题了，那就不要往下看了。

接着用数据库可视化工具打开mysql，我用的是MySQLworkbench，发现有些不久前建立的表出问题了。

于是利用MySQLworkbench导出数据。然后清空原先的数据库。

rm -r /Library/Application\ Support/appsolute/MAMP\ PRO/db/mysql56

　　

目录就是上面的这个。

重新导入数据建立schema，一切OK。
