【MySQL】ERROR! The server quit without updating PID file

Mysql 好久不用，今天启动发现报ERROR! The server quit without updating PID file (/usr/local/mysql/data/ xxxxx.pid）错误

mysql对data目录没有 读写权限引起。

Mac：sudo chmod -R a+rwx /usr/local/mysql/data/

Linux：chown -R mysql:mysql /var/lib/mysql

再次重启：sudo usr/local/mysql/support-files/mysql.server start

 成功启动
