首先把虚拟机配置为桥接模式，然后开启
再你打算修改虚拟机IP之前首先ping下127.0.0.1看看网卡是否是好的（如果127.0.0.1都ping不通的话，那网卡就是坏的了…）[root@localhost /]# ping 127.0.0.1

[root@localhost ~]# service network restart #重启网络

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls ifcfg-ens32 ifdown-bnep ifdown-ippp ifdown-post ifdown-sit ifdown-tunnel ifup-bnep ifup-ippp ifup-plip ifup-ppp ifup-Team ifup-wireless network-functions-ipv6 ifcfg-lo ifdown-eth ifdown-ipv6 ifdown-ppp ifdown-Team ifup ifup-eth ifup-ipv6 ifup-plusb ifup-routes ifup-TeamPort init.ipv6-global ifdown ifdown-ib ifdown-isdn ifdown-routes ifdown-TeamPort ifup-aliases ifup-ib ifup-isdn ifup-post ifup-sit ifup-tunnel network-functions [root@localhost network-scripts]# vi ifcfg-ens32 TYPE="Ethernet" BOOTPROTO="static" #启用静态IP地址 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" IPV6_ADDR_GEN_MODE="stable-privacy" NAME="ens32" UUID="17e371b3-5107-4d72-a58f-e8f71396fd68" DEVICE="ens32" ONBOOT="yes" IPADDR=“192.168.0.121” GATEWAY=“192.168.0.1” 1 2 3 4 5 6 7 8 9 发现ONBOOT=”no”已设置为ONBOOT=”yes”第二步查看：
ping 命令是属于ICMP协议，ping ip地址有效。若直接ping网址（域名），需要配置DNS。编辑添加nameserver如下：vi /etc/resolv.conf
nameserver 8.8.8.8 nameserver 8.8.4.4 1 2 3 【注意】设置完保存！重起 [root@localhost ~]# service network restart #重启网络
再ping
[root@localhost /]# ping www.baidu.com PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data. 64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=1 ttl=55 time=16.9 ms [root@localhost /]#
