# Generated by NetworkManager #啥也没有百度和Google了一下NetworkManager与network可能会出现冲突的情况由于做实验要添加网卡重启服务于是重新配置好DNS文件 [rootopvnserver ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 202.96.128.86
nameserver 202.96.128.166 然后关闭NetworkManager这样就不会出现之前的情况了重新yum安装软件也正常了 [rootopvnserver ~]# systemctl stop NetworkManager
[rootopvnserver ~]# systemctl disable NetworkManager
[rootopvnserver ~]# systemctl restart network更好的方法在网卡配置文件中添加DNS地址格式如下 [rootopvnserver ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPEEthernet
BOOTPROTOstatic
DEFROUTEyes
IPV4_FAILURE_FATALno
NAMEeth0
DEVICEeth0
ONBOOTyes
IPADDR10.0.0.3
GATEWAY10.0.0.254
NETMASK255.255.255.0
DNS1202.96.128.86
DNS2202.96.128.166 注意在centos7.x 中DNS不在 /etc/resolv.conf 中配置了而是直接在网卡配置文件中配置DNS这和centos6.x版本有点区别真是无语改来改去呵呵 转载于:https://www.cnblogs.com/blog-tim/p/10316176.html
