安装Cockpit
web界面访问 https://ip:9090
yum install cockpit cockpit-storaged cockpit-ws cockpit-machines cockpit-docker cockpit-bridge -y
启动Cockpit服务和设置开机自启
systemctl start cockpit
systemctl enable --now cockpit.socket #设置开机自启动同时开启服务一条命令就可以搞定
打开防火墙
firewall-cmd --permanent --zone=public --add-service=cockpit
firewall-cmd --reload
设置主机名
hostnamectl set-hostname myhostname
# 查看开机是否启动
systemctl list-unit-files|grep cockpit
cockpit-motd.service static
cockpit.service static
cockpit.socket enabled
# enabled表示开机启动
# 启动cockpit服务
systemctl start cockpit.service
# 查看状态
systemctl status cockpit.service
# 使用cockpit监听9090端口
yum install net-tools
netstat -tulnp | grep 9090
设置时间同步
yum -y install chrony
systemctl enable chronyd
systemctl start chronyd
vim /etc/chrony.conf
修改时间服务器
server 210.72.145.44 iburst

样例：
[root@localhost ~]# cat /etc/chrony.conf | grep -Ev '^#|^$'
server 210.72.145.44 iburst
server ntp.sjtu.edu.cn iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
