我根据教程《CentOS 6.3 环境搭建discuz论坛 》http://bbs.qcloud.com/thread-1316-1-1.html进行环境搭建部署，发现mysql并不能启动，报错如下：root@VM_203_146_centos bin# service mysqlstartRedirecting to /bin/systemctl start mysql.serviceFailed to issue method call: Unitmysql.service failed to load: No such file or directory.是不是目前命令有改动？附上配置环境log：Last failed login: Sat Feb 27 235939 CST 2016 from 54.251.161.130 on
