Mamp does not start mysql server (mac)

Question

I had a mask and work (wordpress), and I had no problems. Then suddenly the server went down and did not start again. These are some other topics on this topic, but I could not figure it out. I confirmed that no mysql processes are happening .... this is my mysql_error_log:

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.

Answer 1

This means that one of your tables is corrupted. Oddly enough, this happened often in a collision with a car. Here is how I fixed it:

• open my.cnf (in MAMP> File> Modify Template> MySQL)
• add line: innodb_force_recovery = 1
• save and start servers

, , , mysql . , , , : wp_term_taxonomy

. innodb_force_recovery = 1 , : innodb_force_recovery = 2 ( ..) . MySQL : https://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html
