今天上午升级了最新版本的Mac Pro 系统版本到14.0，升级结束后，启动原来安装的Mysql 8.0，一直启动不了。报错:
houxiurong@houxiurong ~$ mysql -uroot -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
通过Bing搜索，给了很多复杂的处理方式，都不行，最后发现是服务在升级MacOS的时候异常停止，重启后没有完全启动。
网友遇到的问题解决方案，尝试好几种方法都不行，最后看了MySQL PID，死活系统找不到，确定是服务没启动。
最后使用方法如下: 一定要 [ sudo 方式 ]
houxiurong@houxiurong ~$ sudo mysql.server start
Password:
Starting MySQL
.Logging to '/usr/local/mysql/data/houxiurong.local.err'.
. SUCCESS!
houxiurong@houxiurong ~$ mysql -uroot -p
Enter password:
