点击start Mysql Server无效
启动失败，报错如下：
system preferences quit unexpectedly while using the MySQL plug-in.
然后运行如下命令：
(base) Nimo-Ding:local Nimo_Ding$ sudo chown -RL root:mysql /usr/local/mysql
Password:
(base) Nimo-Ding:local Nimo_Ding$ sudo chown -RL mysql:mysql /usr/local/mysql/data
(base) Nimo-Ding:local Nimo_Ding$ sudo /usr/local/mysql/support-files/mysql.server start
Starting MySQL
.Logging to ‘/usr/local/mysql/data/Nimo-Ding.local.err’.
SUCCESS!
再查看Mysql服务已正常运行。
