我要配置DNS,修改/etc/resolv.conf,修改后重启服务 service network restart ,修改/etc/resolv.conf的信息丢失,请大家看看。

修改前的配置

# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

 

 

解决方法在ifcfg-eth0 直接加入DNS1=xxx.xxx.xxx.xxx,再service network restart

 

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0C:29:B5:E4:65"
NM_CONTROLLED="yes"
ONBOOT="yes"
IPADDR=192.168.128.133
NETMASK=255.255.255.0
GATEWAY=192.168.128.1
DNS1=222.46.120.6

 

再来查看resolv.conf 多了一行 namerserver xxx.xxx.xxx.xx

Generated by NetworkManager

nameserver 222.46.120.6

 

 

 

还有方法二:

终于找到一篇文章解决了我的问题:http://tech.techweb.com.cn/archiver/tid-380658.html 文章内容: vim /etc/resolvconf/resolv.conf.d/head 文件 显示与resolv.conf相同的内容:

Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

DO NOT EDIT THIS FILE BY HAND – YOUR CHANGES WILL BE OVERWRITTEN)

在最后键入nameserver 202.102.152.3 保存退出, resolvconf -u 此时就可以正常上网了,重启后不用在重新设置DNS了。

 

 

实测:方法1很有效~
