Linux/CentOS设置ip地址及DNS
1.设置静态ip地址：
nano /etc/sysconfig/network-scripts/ifcfg-eth0(可能会有多个网卡eth0,eth1,eth2)
DEVICE=eth0BOOTPROTO=staticHWADDR=00:F1:F3:01:15:4AONBOOT=yesDHCP_HOSTNAME=ehangpcTYPE=EthernetNETMASK=255.255.255.0IPADDR=192.168.0.123GATEWAY=192.168.0.1
2.设置DNS：
nano /etc/resolv.conf
nameserver 202.96.126.165nameserver 202.96.134.133
3.重启网络服务使配置生效：
