【配置网卡信息】不把网卡设置好，则不能与其他机器进行通信网卡配置文件在/etc/sysconfig/network-scripts 里 ifcfg-eno16777736[root@happy network-scripts]# lsifcfg-eno16777736 ifdown-ppp ifup-eth ifup-sitifcfg-lo ifdown-routes ifup-ippp ifup-teamifdown ifdown-sit ifup-ipv6 ifup-teamportifdown-bnep ifdown-team ifup-isdn ifup-tunnelifdown-eth ifdown-teamport ifup-plip ifup-wirelessifdown-ippp ifdown-tunnel ifup-plusb init.ipv6-globalifdown-ipv6 ifup ifup-post network-functionsifdown-isdn ifup-aliases ifup-ppp network-functions-ipv6ifdown-post ifup-bnep ifup-routes

1. 切换到网卡配置文件[root@happy ~]# cd /etc/sysconfig/network-scripts
2. 配置网卡[root@happy network-scripts]# vim ifcfg-eno16777736hwaddr=00:0c:29:b3:64:c2type=ethernetbootproto=staticdefroute=yespeerdns=yespeerroutes=yesipv4,failure,fatal=noipv6init=yesipv6,autoconf=yesipv6,defroute=yesipv6,peerdns=yesipv6,peerroutes=yesipv6,failure,fatal=noname=eno16777736uuid=f1d8f70c-1520-495b-8c1b-f830823d0611onboot=yesipaddr=192.168.6.129netmaske=255.255.255.0gateway=192.168.6.1dns1=192.168.6.1
3. 重启网卡[root@happy network-scripts]# systemctl restart network
4. ping一下[root@happy network-scripts]# ping 192.168.6.129ping 192.168.6.129 (192.168.6.129) 56(84) bytes of data.64 bytes from 192.168.6.129: icmp,seq=1 ttl=64 time=0.051 ms64 bytes from 192.168.6.129: icmp,seq=2 ttl=64 time=0.070 ms64 bytes from 192.168.6.129: icmp,seq=3 ttl=64 time=0.045 ms^c--- 192.168.6.129 ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 1999msrtt min/avg/max/mdev = 0.045/0.055/0.070/0.012 ms配置成功
