The errors I met were below.<\/p>\n
ERROR 2002 (HY000): Can\u2019t connect to local MySQL server through socket \u2018\/var\/mysql\/mysql.sock'(#2), (38)
\nOSError: [Errno 13] Permission denied.
\nThe server quit without updating PID file (\/usr\/local\/var\/mysql\/xxxx.local.pid).
\n#2002 Failure to login MySQL server.<\/p>\n
Finally, I couldn’t access localhost or failed to connect to Wi-Fi.
\n(Maybe this has nothing to do with the server error)<\/p>\n
It seemed the mysql.sock file was not working.
\nFirst, I installed the latest version of MySQL(ver 8.1), but it didn’t work.
\nThen I uninstalled MYSQL and installed ver 5.7, but it didn’t work…
\nI tried the method that google suggested, but none of them solved my error.<\/p>\n
At that time, MYSQL couldn’t be controlled through system preferences.
\nWhen installed ver 8.1, the status turns to start and stop in a few seconds.
\nThen I checked the folder including .sock file, mysql.sock.lock was deleted and appeared every few seconds.
\nThis .sock file was added after ver 5.7.
\nSo I installed ver 5.6 which doesn’t have .sock file, and then everything went smoothly.
\nSomeone suggests to delete this .sock file, But in my case, I couldn’t catch the file.
\nThis is not a fundamental solution, but now my server is working well!!<\/p>\n","protected":false},"excerpt":{"rendered":"
