docker启动mysql反复重启，通过
使用
docker logs 容器ID
chown: cannot read directory '/var/lib/mysql/': Permission denied但是目录权限确认没问题，即使 chmod 777 还是报相同的错误，后来发现是selinux的问题
查看状态
getenforce临时禁用
setenforce 0永久禁用
vi /etc/selinux/config
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disable禁用之后docker启动mysql正常
