导读 | 在Web浏览器中查看服务器并使用鼠标执行系统任务。很容易管理存储、配置网络和检查日志等操作。RHEL 8 自动安装了 Cockpit,Cockpit 所需的防火墙端口会自动打开, Cockpit 界面可用于将基于策略的解密(PBD)规则应用于受管系统上的磁盘。对于在身份管理(IDM)域中注册的系统,Cockpit 默认使用域的集中管理的 IDM 资源。Cockpit 菜单和页面可以在浏览器上导航,可以从 Cockpit Web 界面创建和管理虚拟机。 现在可以将“虚拟机”页面添加到 Cockpit 界面,该界面使用户可以创建和管理基于 libvirt 的虚拟机。 |
环境
Red Hat Enterprise Linux release 8.0
VMware Workstation Pro 14
安装cockpit

[root@localhost ~]# systemctl enable --now cockpit.socket #启用cockpit,设置开机自启动同时开启服务一条命令就可以搞定,Cockpit监听9090端口。 Created symlink /etc/systemd/system/sockets.target.wants/cockpit.socket → /usr/lib/systemd/system/cockpit.socket.

访问cockpit
打开物理机的浏览器输入192.168.10.21:9090访问cockpit服务
通过RHEL8本机的Firefox浏览器输入192.168.10.21:9090访问cockpit服务
用你的系统用户登录即可(通过物理机的浏览器登录即远程登录)
可以设置语言
使用cockpit创建逻辑卷
添加硬盘
重启RHEL8
创建逻辑卷
在系统中查看
