以前一直用 Debian 系，照着官方文档一路装过来都没啥问题，最近想换口味装了个 CentOS 7 ，结果一个 MySQL 就搞了一晚上没搞定。。
大致过程，从官网下了个 Yum Repository
# rpm -ivh mysql57-community-release-el7-8.noarch.rpm # yum update # yum install mysql-community-server 一路顺利，然后启动
# systemctl start mysqld Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details. 报错，照着提示看了下发现并不能看懂。。对着一些信息搜索也无果，求教是什么原因
