RESOLV.CONF Configuration Information Loss resolution

Configure DNS, modify/etc/resolv.conf, restart service network Restart after modification, modify/etc/resolv.conf information loss, please take a look.

[Code] pre-modification configuration

# 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

Baidu on the Internet

Workaround one: Join Dns1=xxx.xxx.xxx.xxx directly in Ifcfg-eth0, then 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

Again to see resolv.conf more a row namerserver xxx.xxx.xxx.xx

# Generated by NetworkManager

NameServer 222.46.120.6

I did not test:

Baidu on the Internet

There are two ways to do it:

Article content:

Vim/etc/resolvconf/resolv.conf.d/head file

Show the same content as resolv.conf:

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

# do not EDIT this FILE by HAND--YOUR changes'll be overwritten)

At the end, type nameserver 202.102.152.3

Save Exit,

Resolvconf-u

At this point, you will be able to surf the internet normally, restart the DNS after restarting.

/etc/resolv.conf file configuration, service network Restart restart is lost, mainly caused by NetworkManager services.

1. Modify the/etc/resolv.conf file to add the nameserver that need to be parsed

[[email protected] root]# cat/etc/resolv.conf # Generated by NetworkManager remarks, this is NetworkManager management # No Nameservers Fou nd 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.comnameserver 10.1.32.16nameservre 8.8.8.8

2. Change the #nm_controlled in the/etc/sysconfig/network-scripts/ifcfg-eth0 file to No

[Email protected] root]# cat/etc/sysconfig/network-scripts/ifcfg-eth0 device= "eth0" hwaddr= "00:26:9e:27:bf:2f" NM_ Controlled= "no" #NM_CONTROLLED改成noONBOOT = "yes" ipaddr=10.43.5.30netmask=255.255.255.0gateway=10.43.5.253

3. Stop the NetworkManager service

[[Email protected] root]# service NetworkManager Statusnetworkmanager is stopped[[email protected] xjb]#

[Email protected] root]# Chkconfig NetworkManager off

4. Restart the network and check

[[email protected] etc]# cat /etc/resolv.conf # generated by  Networkmanager# 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.comnameserver  10.1.32.16nameservre 8.8.8.8[[email protected] etc]# service network   restartshutting down interface eth0:                                [  OK  ]Shutting down loopback interface:                            [  ok  ]bringing up loopback interface:                              [  OK  ]Bringing up interface eth0:                                  [  ok  ][[email protected ] etc]# cat /etc/resolv.conf # generated by networkmanager# 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
