Cockpit是一款自由开源的服务器管理软件，可以通过Web前端界面轻松地管理GNU/Linux服务器，包括：系统、日志、存储、网络、容器、账户、服务、内核转储、软件更新和终端等方面内容。

1、关闭firewalld和SELinux

2、安装cockpit：# yum -y install cockpit

3、启动cockpit：# systemctl start cockpit.service  # ss -tunlp | grep -w :9090

4、配置cockpit开机自启：# systemctl enable cockpit.socket

5、浏览器中访问cockpit web界面：http://192.168.1.146:9090

6、输入服务器192.168.1.146的系统用户名和密码登录cockpit仪表板：

7、安装cockpit扩展模块：

# yum list cockpit*

# yum -y install cockpit-composer cockpit-dashboard cockpit-doc cockpit-docker cockpit-kubernetes cockpit-machines cockpit-machines-ovirt cockpit-packagekit cockpit-pcp cockpit-storaged cockpit-subscriptions cockpit-tests

备注：剩余的cockpit-kdump、cockpit-networkmanager、cockpit-selinux和cockpit-sosreport四个软件包安装时分别会提示如下错误信息，所以上述四个软件包未安装
