之前遇到很多selinux的问题,主要是服务方面的,例如mysql连接问题,单这次遇到这索性记录一下,主要开启关闭配置
现象
file_put_contents(Dockerfile): failed to open stream: Permission denied in
1、查看
[root@localhost Docker-Web]#getenforce
Enforcing
[root@localhost Docker-Web]# sestatus -v

/usr/sbin/sshd system_u:object_r:sshd_exec_t:s0
2、临时关闭
##setenforce 1 设置selinux成为enforcing模式
[root@localhost Docker-Web]# setenforce 0
3、永久关闭
vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled
设置后需要重启才能生效
