ifconfig命令查看当前网卡eno16777736 不同机器可能不一样

[root@localhost network-scripts]# ifconfig
eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.152.130  netmask 255.255.255.0  broadcast 192.168.152.255
        inet6 fe80::20c:29ff:fe26:1ac0  prefixlen 64  scopeid 0x20<link>

编辑网卡，配置静态ip

[root@localhost network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@localhost network-scripts]# ls

ifdown-eth         ifdown-post  ifdown-TeamPort  ifup-eth       ifup-plip  ifup-sit     init.ipv6-global
[root@localhost network-scripts]#

[root@localhost network-scripts]# vim ifcfg-eno16777736
