Мой MySQL, по-видимому, работает неправильно на моем MacOS Catalina (10.15) в соответствии с Homebrew и, согласно моему приложению для wordpress, он не может установить соединение с моим MySQL сервером. Когда я пытаюсь прочитать базу данных в SQL Pro SQL Pro также не может установить sh соединение. Тем не менее, я могу войти в систему MySQL, используя свою терминальную оболочку, что меня смущает.
Что не так с моим MySQL процессом? MySQL вчера работал нормально для моего приложения WordPress. Единственное отличие заключалось в том, что я перезапустил свой компьютер, и теперь я не могу запустить его успешно с помощью homebrew, а WordPress не может установить sh соединение с ним. Вот подробное описание и журналы, касающиеся WordPress и Homebrew
Wordpress
Вчера я перезапустил свой ноутбук, работающий на MacOS, и когда после перезагрузки компьютера я попытался запустить приложение WordPress локально, но wordpress жаловался на ошибку при установлении соединения с базой данных:
Warning: mysqli_real_connect(): Unexpected server response while doing caching_sha2 auth: 109 in /Users/robskrob/code/projects/myblog/wordpress/web/wp/wp-includes/wp-db.php on line 1633
Warning: mysqli_real_connect(): (HY000/2006): MySQL server has gone away in /Users/robskrob/code/projects/kingandpartners/myblog/wordpress/web/wp/wp-includes/wp-db.php on line 1633
MySQL server has gone away
Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at 127.0.0.1. This could mean your host’s database server is down.
Are you sure you have the correct username and password?
Are you sure you have typed the correct hostname?
Are you sure the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
MySQL Журналы Homebrew

System.log
Когда я распечатываю системный журнал на моем компьютере Я вижу эти странные журналы относительно mysql:
Jan 18 13:53:44 Roberts-MBP-4 com.apple.xpc.launchd[1] (homebrew.mxcl.mysql[14913]): Service did not exit 5 seconds after SIGTERM. Sending SIGKILL.
Jan 18 13:53:44 Roberts-MBP-4 com.apple.xpc.launchd[1] (homebrew.mxcl.mysql): This service is defined to be constantly running and is inherently inefficient.
Jan 18 13:53:44 Roberts-MBP-4 com.apple.xpc.launchd[1] (homebrew.mxcl.mysql[17411]): Service exited with abnormal code: 1

Доморощенный форум
Похоже, что зарегистрированная проблема на доморощенных форумах.
Обновление 1
После Инструкция здесь Я выполнил эти команды, чтобы посмотреть, улучшится ли состояние работы mysql:
$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
/Users/robskrob/Library/LaunchAgents/homebrew.mxcl.mysql.plist: Operation now in progress
$ launchctl remove ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
$ rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
В результате, когда я запустил brew services list, я теперь вижу mysql в лучший статус - mysql перешел с error на started и остался на started:
mysql запустил robskrob /Users/robskrob/Library/LaunchAgents/homebrew.mxcl.mysql.plist`
Однако WordPress по-прежнему не может подключиться к mysql.
