RHEL8的 Web Console 是RHEL8的“OEM”，可以在浏览器中对系统进行监控和管理。

第一：启动cockpit 服务并配置firwalld

[root@rhel8server1 ~]# systemctl enable --now cockpit.socket
Created symlink /etc/systemd/system/sockets.target.wants/cockpit.socket → /usr/lib/systemd/system/cockpit.socket.
[root@rhel8server1 ~]# systemctl status cockpit.socket
