Centos7 编辑本地DNS解析配置文件

#配置文件地址：/etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

#添加对应关系
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
xxx.xx.xxx.xx    www.mycentos6.com

# 然后就可以在本机用 www.mycentos6.com 地址访问到xxx.xx.xxx.xx机器
