没有获得 CentOS 7 的静态 IP

我不确定我的静态 IP 缺少什么？

这是我的网络配置文件：

/etc/hosts:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.2 puppet master
192.168.1.3 agent1 machine1
192.168.1.4 agent2 machine2
192.168.1.5 agent3 machine3

/etc/sysconfig/network:

# Created by anaconda
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=agent1
GATEWAY=192.168.1.1

主接口的配置文件/etc/sysconfig/network-scripts/ifcfg-enp0s3：

TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=9b49c161-f7b4-418d-ae5f-a4fae294d302
DEVICE=eth0
ONBOOT=no
IPADDR=192.168.1.3
PREFIX=32
GATEWAY=192.168.1.1
DNS1=192.168.1.1
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

这是输出ip addr：

我已验证我已通过命令连接到互联网ping。

这是目前最新的配置。

请注意，这一切都在 Windows 10 上安装的 VirtualBox 上。我只有两个网络适配器适配器 1 桥接器和适配器 2 主机。

我希望这些信息可以帮助我们识别并解决问题。

将您的名称服务器resolve.conf放入8.8.8.8

编辑你的/etc/sysconfig/network-scripts/ifcfg-enp0s3

ONBOOT=no  
NAME=eth0
DEVICE=eth0

到下面

ONBOOT=yes
NAME=enp0s3
DEVICE=enp0s3

systemctl restart network.service
