Mac navicat连接mysql报2003错误

2003 - Can’t connect to MySQL server on ‘127.0.0.1’ (61 “Connection refused”)

命令行sudo /usr/local/Cellar/mysql/8.0.22_1/support-files/mysql.server start
重新启动mysql，报MySQL server PID file could not be found!
ERROR! The server quit without updating PID file (/usr/local/var/mysql/minxxx.pid
是没有bogon/没有权限，我们给予权限即可
执行：
sudo chmod -R 777 /usr/local/var/mysql/
再启动mysql就成功了！！！
navicat也能连上了！
