title: MySQL Server not starting with MAMP
body: <p>My MySQL Server wont start anymore on MAMP. The solutions I found online said, that I should first quit MAMP, quit the MYSQL process, and start MAMP again.
  But there is no MySQL process running in my situation, so this didn't work. Do you have any idea, what else could be the process?</p>
  
  <p>You can find my error log here:</p>
  
  <blockquote>
    <p>2017-01-20 21:40:03 7fff79bb0000  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 ./yunityproject_wordpress/wp_comments.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. 170120 21:40:04 mysqld_safe mysqld
