Linux修改主機名

伺服器版本: Centos 7.2 參考

臨時修改主機名

hostname 檢視目前系統主機名，知道目前主機名

hostname 要修改的主機名

[[email protected] ~]# hostname masteryee-one
[[email protected] ~]# hostname
masteryee-one
           

永久修改主機名

當然在centos7特地添加了 hostnamectl 指令檢視，修改主機名

[[email protected] ~]# hostnamectl
   Static hostname: i-9s7be0le
Transient hostname: masteryee-one
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 668a8a15b473b53db8a06eba66cbc862
           Boot ID: b7a67567d7624913a7b25cfac8cc6bf5
    Virtualization: kvm
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-327.4.5.el7.x86_64
      Architecture: x86-64
           

使用 hostnamectl set-hostname 指令修改主機名，可永久生效：

[[email protected] ~]# hostnamectl set-hostname masteryee-one
[[email protected] ~]# hostname
masteryee-one
[[email protected] ~]# hostnamectl
   Static hostname: masteryee-one
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 668a8a15b473b53db8a06eba66cbc862
           Boot ID: b7a67567d7624913a7b25cfac8cc6bf5
    Virtualization: kvm
