docker报错 Failed to get D-Bus connection: Operation not permitted

[root@qqqqqqqqqqqq ~]# docker run -d -p 80:80 local/c7-systemd-httpd

[root@qqqqqqqqqqqq ~]# docker exec -it 80 bash

[root@80185599c949 /]# yum -y install memcached

进入到容器内，安装了memcached后报错

[root@80185599c949 /]# systemctl start memcached
Failed to get D-Bus connection: Operation not permitted

原因及解决方式： 
这个的原因是因为dbus-daemon没能启动。其实systemctl并不是不可以使用。将你的CMD或者entrypoint设置为/usr/sbin/init即可。会自动将dbus等服务启动起来。

启动时候增加 --privileged
[root@qqqqqqqqqqqq ~]# docker run -d --privileged -p 80:80 local/c7-systemd-httpd
