Linux中如何直接ping 主机名

本文主要是介绍Linux中如何直接ping 主机名，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

[root@hadoop7 redis01]# vi /etc/hosts127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.238.20   hadoop7 

vi修改/hosts文件，在最下面加上一行192.168.238.20 hadopp7（本机IP 主机名）

改完之后测试一下，ping本机IP。。。ok，ping主机名。。也通了。

"/etc/hosts" 3L, 218C written[root@hadoop7 redis01]# ping 192.168.238.20
