在CentOS 7.8环境下，当尝试在Docker容器内使用systemctl命令管理firewalld服务时，遇到了错误提示：'System has not been booted with systemd as init system (PID 1). Can't operate.' 和 'Failed to connect to bus: Host is down'。解决方案是在启动Docker容器时添加--privileged参数，如：`docker run -it --name c8 --privileged centos /usr/sbin/init`。之后，可以正常进入容器并使用systemctl命令。

环境centos7.8

docker容器使用systemctl命令报错：

[root@d7a74069b83c yum.repos.d]# systemctl status firewalld
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

solution：

启动容器时加入参数 --privileged

[root@localhost ~]# docker run -itd --name c8 --privileged centos /usr/sbin/init

[root@localhost ~]# docker exec -it c8 /bin/bash
