| - 由于前面虚拟机中安装 CentOS 使用的是桥接模式，为了让虚拟机中的系统能上网，我们需要进行网络设置。 | ||
|

| <h2 id="networkSettings1">界面化下设置网络（新手推荐使用这种）</h2> | ||
|
|
||
| -  | ||
| - 选择上图箭头所示 | ||
| -  | ||
| - 如上图标注 3 所示：选择 `手动` 模式 | ||
| - 如上图标注 4 所示：填写自己局域网内的子网掩码、默认网关，以及你要分配的内网 IP 地址。这三个参数你可以参考你当前使用的主机信息，在 Windows 系统上使用：`cmd --- ipconfig`，查看你当前连接的网卡信息。如果你是无线网卡则读取对应的无线网卡信息，如果你是本地连接，则读取对应的本地连接信息。 | ||
| - 如上图标注 5 所示：填写你当前地区合适的 DNS 地址，我这边地区使用 360 测试出来的结果显示 114 的适合我，所以我这里填写该值 | ||
|
|
||
|
|
||
| <h2 id="networkSettings2">命令行下设置网络</h2> | ||
|
|
||
| - 编辑网卡信息： | ||
| - 备份：`cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0-20160205Back` | ||
| - 把备份文件移动到其他目录：`mv /etc/sysconfig/network-scripts/ifcfg-eth0-20160205Back /opt/myBack` | ||
| - 编辑网卡文件：`vim /etc/sysconfig/network-scripts/ifcfg-eth0` | ||
| - 把网卡中信息改为下面对应内容： | ||
| ``` | ||
| DEVICE=eth0 (系统默认值) | ||
| TYPE=Ethernet (系统默认值) | ||
| UUID=a2c17f0c-a224-43d5-a203-48af1f0d9113 (系统默认值) | ||
| ONBOOT=yes (系统默认值是 no,我改为 yes) | ||
| NM_CONTROLLED=yes (系统默认值) | ||
| BOOTPROTO=none (系统默认值是 dhcp,我改为 none,代表手动) | ||
| USERCTL=no (自己补充的) | ||
| IPV6INIT=no (自己补充的) | ||
| NETMASK=255.255.255.0 (自己补充的) | ||
