CentOS下永久修改主机名

永久修改主机名

[root@centos7 ~]# hostnamectl set-hostname zhusaiwei-hbza            # 使用这个命令会立即生效且重启也生效

[root@centos7 ~]# hostname                                                 # 查看下

centos77.magedu.com

[root@centos7 ~]# vim /etc/hosts                                           # 编辑下hosts文件, 给127.0.0.1添加hostname

 

 

[root@centos7 ~]# cat /etc/hosts                                           # 检查127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 zhusaiwei-hbza

                           ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 

 这就修改完了,重启后查看主机名
