我让mysql在我的mac上运行良好，运行速度很高，10.13.5。然而，昨晚，由于一些未知的原因，系统在半夜重新启动，此后我一直无法恢复正常运行。
当我跑的时候 brew services start mysql 我得到： Successfully started mysql数据库 (label: homebrew.mxcl.mysql) 作为回应。然而， ps aux | grep mysql 显示没有正在运行的服务器，我无法登录mysql。如果我跑了， mysql.server start 我得到： . ERROR! The server quit without updating PID file (/usr/local/var/mysql/iMac-5K-3.local.pid). 错误文件内容如下：
