进入到网卡配置文件所在的目录，然后编辑网卡配置文件填入下面的信息：

[root@linuxprobe ~]# cd /etc/sysconfig/network-scripts/
[root@linuxprobe network-scripts]# vim ifcfg-eno16777736
TYPE=Ethernet
BOOTPROTO=static
NAME=eno16777736
ONBOOT=yes
IPADDR=192.168.10.10
NETMASK=255.255.255.0
GATEWAY=192.168.10.1
DNS1=192.168.10.1

执行重启网卡设备的命令，正常情况不会有提示信息，然后通过ping命令测试网络能否联通。

[root@linuxprobe network-scripts]# systemctl restart network
[root@linuxprobe network-scripts]# ping 192.168.10.10

ifconfig用于获取网卡配置与网络状态等信息:格式为"ifconfig [网络设备] [参数]"。查看本机当前的网卡配置与网络状态等信息，咱们主要就是看每段开头的网卡名称、inet参数后面的IP地址、ether参数后面的物理mac地址以及RX、TX的接收与发送数据包的大小http://www.linuxprobe.com/chapter-02.html#24：
