如何在不删除并重新安装的情况下解决MySQL没有启动MAMP？

Question

I am unable to get MySQL running on MAMP. Other documentation on this site is suggesting to delete it all and reinstall MAMP again. I was in the middle of a WordPress theme development project and had already built the database for it, so this is not an option for me. This is the error log:

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.
170225 17:42:34 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended

I really have no clue what this is telling me. There are no current MySQL processes running, at least that is what I gathered from this:

danales-MacBook-Pro:~ danale$ killall -9 mysqld
No matching processes belonging to you were found

I am using a MacBook Pro Sierra. Please help.

Remove all files (but not directories) in the mysql dir: rm /Applications/MAMP/db/mysql/

Files may be causing the issue, i suggest copy them somewhere before doing this.
