### Virtualbox centos7配置网络桥接实现内外网连通 ###

*   *  1. 配置virtualbox网络
     *   *  1.1 查看本机\`IP\`。
         *  1.2 找到\`VirtualBox Host-Only Network\`，配置网络
     *  2. virtualbox设置centos系统网络桥接
     *  3. centos系统配置网络
     *  4. 重启centos系统的网络服务
     *  5. 校验访问 内网和外网

centos7 镜像安装资源可查看上文：[Virtualbox新装centos7重置root密码][Virtualbox_centos7_root]

使用virtualbox安装完成后，需要在虚拟机管理台进行网络配置并修改centos配置文件后，才能进行内网和外网的访问。（window下安装的virtualbox）

## 1. 配置virtualbox网络 ##

### 1.1 查看本机`IP`。 ###

在`CMD`工具输入`ipconfig`可查看 `IPv4`地址。假如是`192.168.0.53`

### 1.2 找到`VirtualBox Host-Only Network`，配置网络 ###

打开`控制面板\所有控制面板项\网络连接`，找到`VirtualBox Host-Only Network`，配置网络。  
上图示本机ip是`192.168.0.x`，所以把`VirtualBox Host-Only Network`的IP设置同一网段`192.168.0.111`，子网掩码也配置成`255.255.255.0`。如图

## 2. virtualbox设置centos系统网络桥接 ##

如下图从左到右的配置

## 3. centos系统配置网络 ##

1.ssh登录centos7系统，进入系统网络配置目录

$ cd /etc/sysconfig/network-scripts/
    $ ls

2. 编辑`ipcfg-enp0s3`文件

$ vi ifcfg-enp0s3

按示例进行文档编辑

TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=dhcp
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=enp0s3
    UUID=18900bd0-ac26-498b-9683-1ea111d4ca5e
    DEVICE=enp0s3
    ONBOOT=yes
    IPADDR=192.168.0.222
    NETMASK=255.255.255.0
    GATEWAY=192.168.0.1
    DNS1=192.168.0.1
    DNS2=192.168.0.1

## 4. 重启centos系统的网络服务 ##

$ service network restart

## 5. 校验访问 内网和外网 ##

# 访问内网
    $ ping 192.168.0.1 -c4
    
    # 访问外网
    $ ping baidu.com -c4

如下图显示结果，表示已联通内网和外
