在Mac上通過brew install mysql 安裝了完mysql

執行mysql.server start

報錯：ERROR! The server quit without updating PID file (/usr/local/var/mysql/chenyuntekiMacBook-Air.local.pid).

nano /usr/local/var/mysql/chenyuntekiMacBook-Air.local.err 

檢視錯誤資訊發現：The error means mysqld does not have the access rights to the directory 

猜測是檔案許可權的問題

執行：chmod -R 777 /usr/local/var/mysql/

問題解決！
