1、配置网络

（1）为网卡添加一个会话static，在此会话配置ip地址为x.x.x.123

[root@server1 network-scripts]# nmcli connection add type ethernet con-name static ifname ens192 ipv4.addresses '192.168.123.123/24' ipv4.routes '192.168.0.0/16' ipv4.gateway 192.168.123.2 ipv4.dns '8.8.8.8' ipv4.method manual autoconnect yes
Connection 'static' (fd1067f8-9ca7-43be-a783-d3e7792ca85e) successfully added.

在这里插入图片描述

（2）测试网络连通性，看是否能够ping通百度，并把百度首页文件下载下来

[root@server1 ~]# ping www.baidu.com
PING www.a.shifen.com (14.215.177.39) 56(84) bytes of data.
64 bytes from 14.215.177.39 (14.215.177.39): icmp_seq=1 ttl=128 time=6.32 ms

[root@server1 ~]# ll -d index.html

（3）设置系统开机时，该网卡通过DHCP协议自动获取IP地址

[root@server1 network-scripts]# vim /etc/sysconfig/network-scripts/ifcfg-static

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp  改为dhcp即可
IPADDR=192.168.123.123
PREFIX=24
GATEWAY=192.168.123.2
DNS1=8.8.8.8
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=static
UUID=f1f5cbfc-fe41-4c14-998a-fbd9828cedec
DEVICE=ens192
ONBOOT=yes
