RedHat5.5的/etc/resolv.conf文件被复写的解决

公司RedHat5.5系统，配置了/etc/resolv.conf文件后重启网络服务，此文件内容就被复写了。经过查看红帽官方文档，给出以下解决办法。https://access.redhat.com/site/solutions/61921

问题主要原因是启用了networkmanager服务，个人觉得是此服务接管了原有的网络设置。

解决办法是配置networkmanager的配置文件。

1.创建一个脚本。vim /etc/NetworkManager/dispatcher.d/15-resolv

内容为：

# vim /etc/NetworkManager/dispatcher.d/15-resolv

#!/bin/bash

#

# Description : script to override default resolv.conf file

# with customized file.

cp -f /etc/resolv.conf.custom /etc/resolv.conf

2.设置文件权限

# chmod u+x /etc/NetworkManager/dispatcher.d/15-resolv

3.创建一个文件 vi /etc/resolv.conf.custom

nameserver xx.xx.xx.xx

options single-request-reopen

4.重启服务

service NetworkManager restart
