Linux之hostnamectl修改主机名

---

查看主机信息，第一个就是主机名

[root@localhost ~]# hostnamectl 
   Static hostname: localhost.localdomain
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 867aaa1c353c4aad8510c0ee973bc083
           Boot ID: 6f9f8d5dd4f7426daff92ee2e0b736cf
    Virtualization: kvm
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-693.11.1.el7.x86_64
      Architecture: x86-64

设置主机名 

[root@localhost ~]# hostnamectl set-hostname test-vm-1

再查看主机信息，第一个就是主机名

[root@localhost ~]# hostnamectl 
   Static hostname: test-vm-1
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 867aaa1c353c4aad8510c0ee973bc083
           Boot ID: 6f9f8d5dd4f7426daff92ee2e0b736cf
    Virtualization: kvm
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-693.11.1.el7.x86_64
      Architecture: x86-64

然后重启 reboot

[root@localhost ~]# reboot

重启后很清晰

[root@test-vm-1 ~]#
