使用 hostnamectl 查看主机信息

xx@xx-server:~$ hostnamectl
   Static hostname: xx-server
         Icon name: computer-vm
           Chassis: vm
        Machine ID: xxx..
           Boot ID: xxx..

更新主机名称

sudo hostnamectl set-hostname new-host-name

xx@xx-server:~$ hostnamectl
   Static hostname: new-host-name
         Icon name: computer-vm
           Chassis: vm
        Machine ID: xxx..
