Liunx靜態IP設置
1.登入配置文件目錄
運行命令：cd /etc/sysconfig/network-scripts
2.查看網卡信息
運行命令：ll

可以看到網卡配置文件ifcfg-eno16777728
3.查看編輯網卡信息
運行命令：vi ifcfg-eno16777728
TYPE="Ethernet"
BOOTPROTO="dhcp"
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="eno16777728"
UUID="c93b2e5c-93ff-443f-8583-69717f317a28"
DEVICE="eno16777728"
ONBOOT="no"
可以看出BOOTPROTO="dhcp"表示系統自動獲取IP
4.修改配置文件
修改BOOTPROTO="dhcp"爲BOOTPROTO="static"
修改ONBOOT="no"爲ONBOOT="yes"
添加一下配置信息
IPADDR=192.168.0.1 #ip地址
NETMASK=255.255.255.0 #子網掩碼
GATEWAY=192.168.0.2 #默認網關
DNS1=186.76.76.76 #DNS域名解析服務器
DNS2=8.8.8.8
設置DNS
運行命令：vi /etc/resolv.conf
nameserver 186.76.76.76
nameserver 8.8.8.8
修改內容如上所示或者其他的DNS服務器均可
5.重啓網絡服務(重啓網卡)
運行命令：service network restart
6.查看系統IP配置
運行命令：ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eno16777728: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

link/ether 52:54:00:9b:94:5d brd ff:ff:ff:ff:ff:ff
inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0

可以看到網卡eno16777728已被修改
