centos 设置静态IP

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]# ls
ifcfg-eno16777736  ifdown-ppp       ifup-ib      ifup-Team
ifcfg-lo           ifdown-routes    ifup-ippp    ifup-TeamPort
ifdown             ifdown-sit       ifup-ipv6    ifup-tunnel
ifdown-bnep        ifdown-Team      ifup-isdn    ifup-wireless
ifdown-eth         ifdown-TeamPort  ifup-plip    init.ipv6-global
ifdown-ib          ifdown-tunnel    ifup-plusb   network-functions
ifdown-ippp        ifup             ifup-post    network-functions-ipv6
ifdown-ipv6        ifup-aliases     ifup-ppp
ifdown-isdn        ifup-bnep        ifup-routes
ifdown-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=15.238.88.255
IPADDR=15.238.88.163
NETMASK=255.255.255.0
GATEWAY=15.238.88.252
DNS1=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。
