本地部署mysql服务，某天突然停电，导致数据库服务器重启了，然后第二天发现数据服务没有起来，mysql设置开机自启了，还是没有正常启动。登陆上去一看报错信息入下：

经过排查没有问题，也不是目录损坏，都正常之后，mysql服务还是不能启动。然后突然想到防火墙查看防火墙也是正常的。然后想到欧拉系统的selinux服务需要手动设置成disabled。才能正常启动，于是把seliunx设置成disabled，之前部署时临时设置成0了，所以导致服务器重启后，mysql服务设置开机自启也没有启动起来。临时关闭一下seliunx服务（setenforce 0）再重启一下mysql服务就正常了。

#设置seliunx

bash 复制代码

setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
