CentOS6.x DNS配置[解决重启dns配置丢失]

之前用5.5的时候，

只需要修改一下 /etc/resolv.conf

<wbr><wbr><wbr><wbr><wbr>修改内容：<wbr> nameserver xxx.xxx.xxx.xxx</wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>nameserver xxx.xxx.xxx.xxx</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

但在6.4下， service network restart 重启一下网络，resolv.conf又变回默认的了

<wbr></wbr>

6.4解决方法

直接在<wbr>/etc/sysconfig/network-scripts/ifcfg-eth0[x] 下修改</wbr>

增加：

<wbr>DNS1:XXX.XXX.XXX.XXX</wbr>

<wbr>DNS2:XXX.XXX.XXX.XXX</wbr>

<wbr>service network restart下，<wbr> vi/etc/resolv.conf</wbr></wbr>

就会看到：

<wbr> nameserver xxx.xxx.xxx.xxx</wbr>

<wbr> nameserver xxx.xxx.xxx.xxx</wbr>

<wbr></wbr>

<wbr></wbr>

注意：设置前请先备份配置文件
