centos默认安装好之后一般是自动分配本地ip，局域网外电脑是无法找到的。一般我们要设置静态IP。

1. 先查看默认ip

[root@localhost bin]# cd /etc/sysconfig/network-scripts[root@localhost network-scripts]# lsifcfg-eno16777736  ifdown-ppp       ifup-ib      ifup-Teamifcfg-lo           ifdown-routes    ifup-ippp    ifup-TeamPortifdown             ifdown-sit       ifup-ipv6    ifup-tunnelifdown-bnep        ifdown-Team      ifup-isdn    ifup-wirelessifdown-eth         ifdown-TeamPort  ifup-plip    init.ipv6-globalifdown-ib          ifdown-tunnel    ifup-plusb   network-functionsifdown-ippp        ifup             ifup-post    network-functions-ipv6ifdown-ipv6        ifup-aliases     ifup-pppifdown-isdn        ifup-bnep        ifup-routesifdown-post        ifup-eth         ifup-sit[root@localhost network-scripts]# gedit ifcfg-eno16777736

打开默认配置：

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="157c8fb5-23b3-414c-8519-25bef9b20a54"DEVICE="eno16777736"ONBOOT="yes"

以下是要修改的内容

TYPE="Ethernet"BOOTPROTO="static"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="ens33"UUID="8ee24af1-39b1-428d-83b0-13017df6f844"DEVICE="ens33"ONBOOT="yes"BROADCAST=15.238.88.255IPADDR=15.238.88.163NETMASK=255.255.255.0GATEWAY=15.238.88.252DNS1=15.238.81.207

 

2. 重启服务

service network restart

3. 修改虚拟机配置网络适配器，为桥接模式。
