【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]# ls
ifcfg-eno16777736  ifdown-ppp       ifup-eth     ifup-sit
ifcfg-lo           ifdown-routes    ifup-ippp    ifup-Team
ifdown             ifdown-sit       ifup-ipv6    ifup-TeamPort
ifdown-bnep        ifdown-Team      ifup-isdn    ifup-tunnel
ifdown-eth         ifdown-TeamPort  ifup-plip    ifup-wireless
ifdown-ippp        ifdown-tunnel    ifup-plusb   init.ipv6-global

网卡类型     TYPE=Ethernet
地址分配模式 BOOTPROTO=static
网卡名称     NAME= eno16777736
是否启动     ONBOOT=yes
IP地址       IPADDR=192.168.6.129
子网掩码     NETMASK=255.255.255.0
网关地址     GATEWAY=192.168.6.1
DNS地址      DNS1=192.168.6.1

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-eno16777736
HWADDR=00:0C:29:B3:64:C2
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=f1d8f70c-1520-495b-8c1b-f830823d0611
ONBOOT=yes
IPADDR=192.168.6.129
NETMASKE=255.255.255.0
GATEWAY=192.168.6.1
DNS1=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 192.168.6.129
