1.登入配置檔案目錄
執行命令：cd /etc/sysconfig/network-scripts
2.檢視網絡卡資訊
執行命令：ll

onboot=

bootproto="dhcp"表示系統自動獲取ip
4.修改配置檔案
修改bootproto="dhcp"為bootproto="static"
修改onboot="no"為onboot="yes"
新增一下配置資訊
ipaddr=192.168.0.1 #ip位址
netmask=255.255.255.0 #子網掩碼
gateway=192.168.0.2 #預設閘道器
dns1=186.76.76.76 #dns網域名稱解析伺服器
dns2=8.8.8.8
執行命令：vi /etc/resolv.conf
nameserver 186.76.76.76
nameserver 8.8.8.8
5.重啟網路服務(重啟網絡卡)
執行命令：service network restart
6.檢視系統ip配置
執行命令：ip addr
