本篇文章主要介紹了Centos 7開(kāi)啟網(wǎng)卡自動(dòng)獲取IP的詳細(xì)方法，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧

Centos7默認(rèn)安裝是沒(méi)有開(kāi)啟配置網(wǎng)卡信息的，無(wú)法訪問(wèn)外網(wǎng)。

下邊配置打開(kāi)網(wǎng)絡(luò)自動(dòng)獲取Ip地址

1.查看網(wǎng)卡信息

執(zhí)行Ifconfig

eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

    inet6 fe80::20c:29ff:fee8:8637 prefixlen 64 scopeid 0x20<link>

    ether 00:0c:29:e8:86:37 txqueuelen 1000 (Ethernet)

    RX packets 1121 bytes 98968 (96.6 KiB)

    RX errors 0 dropped 0 overruns 0 frame 0

    TX packets 179 bytes 25233 (24.6 KiB)

    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

    inet 127.0.0.1 netmask 255.0.0.0

    inet6 ::1 prefixlen 128 scopeid 0x10<host>

    loop txqueuelen 0 (Local Loopback)

    RX packets 900 bytes 78372 (76.5 KiB)

    RX errors 0 dropped 0 overruns 0 frame 0

    TX packets 900 bytes 78372 (76.5 KiB)

    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

1.eno16777736代表網(wǎng)卡的名稱，ether 00:0c:29:e8:86:37代表網(wǎng)卡的Mac地址

2.配置網(wǎng)卡開(kāi)始網(wǎng)絡(luò)連接

cd /etc/system/network-scripts/

vi ifcfg-eno16777736

HWADDR=00:0C:29:E8:86:37
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=eno16777736
UUID=79d6c916-aab8-45e4-a163-37ae73393d26
ONBOOT=no

將ONBOOT= no改成ONBOOT=yes

3.重啟網(wǎng)絡(luò)

service network restart

4.再執(zhí)行ifconfig

eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
    inet 192.168.159.128 netmask 255.255.255.0 broadcast 192.168.159.255
    inet6 fe80::20c:29ff:fee8:8637 prefixlen 64 scopeid 0x20<link>
    ether 00:0c:29:e8:86:37 txqueuelen 1000 (Ethernet)
    RX packets 1699 bytes 140091 (136.8 KiB)
    RX errors 0 dropped 0 overruns 0 frame 0
    TX packets 333 bytes 42669 (41.6 KiB)
    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
    inet 127.0.0.1 netmask 255.0.0.0
    inet6 ::1 prefixlen 128 scopeid 0x10<host>
    loop txqueuelen 0 (Local Loopback)
    RX packets 900 bytes 78372 (76.5 KiB)
    RX errors 0 dropped 0 overruns 0 frame 0
    TX packets 900 bytes 78372 (76.5 KiB)
    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

inet 192.168.159.128 代表IP地址
