静态IP设置(基于CentOS7)

概述:
1、ifconfig改成了 ip addr,
2、CentOS 7.0默认使用的是firewall作为防火墙,这里改为iptables防火墙。
firewall:
systemctl start firewalld.service#启动firewall
systemctl stop firewalld.service#停止firewall
systemctl disable firewalld.service#禁止firewall开机启动

接下来配置网络:

1、查看当前网卡

 

[root@master cdh]# ip addr
1: lo:  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: eno16777736:  mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:a6:e3:af brd ff:ff:ff:ff:ff:ff
    inet 192.168.41.160/24 brd 192.168.41.255 scope global eno16777736
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fea6:e3af/64 scope link 
       valid_lft forever preferred_lft forever

备注:这里我已经是修改好了的,所以可以看到我设置的。记住eno16777736这个网卡,接下来找到这个文件。

2、进入到 cd /etc/sysconfig/network-scripts/

 

 

[root@master network-scripts]# cd /etc/sysconfig/network-scripts/
[root@master network-scripts]# ls
ifcfg-eno16777736  ifdown-ib    ifdown-ppp       ifdown-tunnel  ifup-ib    ifup-plusb   ifup-Team         network-functions
ifcfg-lo           ifdown-ippp  ifdown-routes    ifup           ifup-ippp  ifup-post    ifup-TeamPort     network-functions-ipv6
ifdown             ifdown-ipv6  ifdown-sit       ifup-aliases   ifup-ipv6  ifup-ppp     ifup-tunnel
ifdown-bnep        ifdown-isdn  ifdown-Team      ifup-bnep      ifup-isdn  ifup-routes  ifup-wireless
ifdown-eth         ifdown-post  ifdown-TeamPort  ifup-eth       ifup-plip  ifup-sit     init.ipv6-global

 

 

 

 
 

3、修改

 

 

[root@master network-scripts]# vi ifcfg-eno16777736


4、

找到对应的内容(HWADDR、BOOTPROTO、ONBOOT、IPADDR、NETMASK、GATEWAY和DNS):
uTYPE=Ethernet
HWADDR=00:0c:29:a6:e3:af #你机器的mac地址
BOOTPROTO=static   #静态ip
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=ff2cf6f2-49fc-49fa-8ec0-6facf1ddb832 #uuid 不重复就行
DEVICE=eno16777736
ONBOOT=yes
IPADDR=192.168.41.160  #静态ip 地址
PREFIXO=24
NETMASK=255.255.255.0  #网关
GATEWAY=192.168.41.2   #子网掩码
DNS1=192.168.41.2	   #主DNS
DNS2=8.8.8.8           #备用DNS

保存退出

 


5、重启网卡

 

[root@master network-scripts]# systemctl  restart network

 

 

6、验证

 

[root@master network-scripts]# ip addr 

就可以看到自己配置的静态ip了。
