IPADDR=192.168.1.111NETMASK=255.255.255.0GATEWAY=192.168.1.1DNS1=8.8.8.8DNS2=8.8.8.8
三、重启网络服务
[root@localhostDesktop]#servicenetworkrestartShuttingdowninterfaceeth0:Devicestate:3(disconnected)[OK]Shuttingdownloopbackinterface:[OK]Bringinguploopbackinterface:[OK]Bringingupinterfaceeth0:Activeconnectionstate:activatingActiveconnectionpath:/org/freedesktop/NetworkManager/ActiveConnection/20state:activatedConnectionactivated[OK]
四、测试，收到数据即配置完成！
[root@localhostnetwork-scripts]#pingPINGwww.(119.75.217.109)56(84)bytesofdata.64bytesfrom119.75.217.109:icmp_seq=1ttl=55time=1.52ms64bytesfrom119.75.217.109:icmp_seq=2ttl=55time=1.67ms64bytesfrom119.75.217.109:icmp_seq=3ttl=55time=1.89ms64bytesfrom119.75.217.109:icmp_seq=4ttl=55time=1.99ms64bytesfrom119.75.217.109:icmp_seq=5ttl=55time=1.84ms64bytesfrom119.75.217.109:icmp_seq=6ttl=55time=1.71ms64bytesfrom119.75.217.109:icmp_seq=7ttl=55time=1.98ms64bytesfrom119.75.217.109:icmp_seq=8ttl=55time=1.86ms
