linux - 如何在 CentOS 中更改静态 IP 地址？

Question

当我在 eth0 中更改 IP 地址时遇到问题

     ,actual thing is happening is when i changed the ip-address its changed but when i 
     restart network service it comes in back state that means its again showing old ip-
     address.

//   ~/etc/sysconfig/network/ifcfg-eth0

        but its showing **access denied**

    please help me why its happening?

Answer 1

以root身份登录

编辑文件/etc/sysconfig/network/ifcfg-eth0 (重要提示:不要在路径开头写波浪号~)

根据其文档修改此文件，例如:https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s1-networkscripts-interfaces.html

保存文件后，IP 地址不会立即更改。做一个service network restart或 reboot ，然后更改将生效。

注意:您也可以使用 sudo 代替 root 登录如果 sudo 已正确配置，则用于从您的普通非特权帐户进行修改。
