CentOS 6.6 Implements a method for permanently modifying a DNS address _ server Other

The example in this article describes the CentOS 6.6 implementation method for permanently modifying DNS addresses. Share to everyone for your reference, specific as follows:

1. Configure IP address file /etc/sysconfig/network-scripts/ifcfg-eth0

Add a line:

Copy Code code as follows:

dns1=8.8.8.8 #手动添加一个dns地址;

The address of the DNS profile/etc/resolv.conf will automatically match the manually added address, and will not be purged after the network card is restarted;

2. Add DNS Address manually

DNS configuration file/etc/resolv.conf

Copy Code code as follows:

NameServer 192.168.1.17

Configure IP Address file/etc/sysconfig/network-scripts/ifcfg-eth0

Add to:

Copy Code code as follows:

Peerdns=no #添加后不会去打扰/etc/resolv.conf File

In a DHCP environment, when/etc/resolv.conf manually add a DNS address, the network adapter is automatically removed, and the DNS address added to/etc/sysconfig/network-scripts/ifcfg-eth0 is not cleared;

Static configuration of IP environment,/etc/resolv.conf Manually add DNS address, reboot will not clear.

I hope this article will help you CentOS server management.
