centos6.magedu.com

NETWORKING=yes
HOSTNAME=centos66.magedu.com
[root@centos6 ~]$ hostname centos66.magedu.com                          # 设置当前的hostname(立即生效)
[root@centos6 ~]$ vim /etc/hosts                                        # 编辑hosts文件,给127.0.0.1添加hostname

[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
