CentOS 7设置联网

1、查看网卡

​ 此处网卡名称为ens33

[root@localhost ~]# ip addr

[root@localhost ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    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: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:e1:40:49 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.107/24 brd 192.168.1.255 scope global noprefixroute dynamic ens33
       valid_lft 5744sec preferred_lft 5744sec
    inet6 fe80::4f6e:679d:1701:cef9/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

2、修改配置文件

​ 把ONBOOT改为yes

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33

  1 TYPE=Ethernet
  2 PROXY_METHOD=none
  3 BROWSER_ONLY=no
  4 BOOTPROTO=dhcp
  5 DEFROUTE=yes
  6 IPV4_FAILURE_FATAL=no
  7 IPV6INIT=yes
  8 IPV6_AUTOCONF=yes
  9 IPV6_DEFROUTE=yes
 10 IPV6_FAILURE_FATAL=no
 11 IPV6_ADDR_GEN_MODE=stable-privacy
 12 NAME=ens33
 13 UUID=953801cc-367c-4bb0-af20-16efaf6c0b61
 14 DEVICE=ens33
 15 ONBOOT=yes

3、在虚拟机上设置网络连接为桥接模式并勾选复制物理网络连接状态

4、安装ifconfig

​ yum-y install net-tools
