CentOS6重启后DNS被还原的解决办法
http://luyx30.blog.51cto.com/1029851/1070765/
centos6.5的64位系统,修改完/etc/sysconfig/network-script/ifcfg-eth0之后重启,竟然又恢复回去,
原来是NetworkManager服务在作怪,关闭他,再修改,重启就不会变不回去了。
openvz的虚拟VPS的默认网卡是venet0,没有eth0,则修改 /etc/sysconfig/network-scripts/ifcfg-venet0
临时关闭:service NetworkManager stop
永久关闭:chkconfig NetworkManager off
修改并备份
vim /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 127.0.0.1
nameserver 4.2.2.2
nameserver 208.67.222.222
nameserver 208.67.222.220
cp /etc/resolv.conf /etc/resolv.conf.bak
vim /etc/sysconfig/network-scripts/ifcfg-venet0
vim /etc/sysconfig/network-scripts/ifcfg-venet0:0
DNS1=8.8.8.8
DNS2=8.8.4.4
PEERDNS=no
cp /etc/sysconfig/network-scripts/ifcfg-venet0 /etc/sysconfig/network-scripts/ifcfg-venet0.bak
cp /etc/sysconfig/network-scripts/ifcfg-venet0:0 /etc/sysconfig/network-scripts/ifcfg-venet0:0.bak
