# 设置apt通过代理安装软件

在Ubuntu上安装软件时，如果需要使用代理服务器，可以在`/etc/apt/apt.conf`中设置，添加如下行：

```
Acquire::http::Proxy "http://yourproxyaddress:proxyport";
```

如果代理服务器需要密码和账号登陆，则将

```
"http://yourproxyaddress:proxyport";
```

修改成

```
"http://username:password@yourproxyaddress:proxyport";
```

> 共享上网的HTTP代理可以采用[Polipo:小巧的web代理服务器](https://github.com/huataihuang/cloud-atlas-draft/tree/b8ddb8068dccea09024fc5bfd3bfc53b7dc0e5c2/service/proxy/polipo/README.md)

## proxy.conf

现在比较新的Ubuntu版本，有关apt的配置都存放在 `/etc/apt/apt.conf.d` 目录下，所以建议将代理配置设置为 `/etc/apt/apt.conf.d/proxy.conf`

```
Acquire::http::Proxy "http://user:password@proxy.server:port/";
Acquire::https::Proxy "http://user:password@proxy.server:port/";
```
