# Redsocks

在windows上，我们可以安装proxifier来做sock5代理，在centos上，我们可以安装Redsocks来做代理。

## 1、安装依赖

```
$ yum -y install libevent-devel git gcc
```

## 2、下载源码与编译

```
$ git clone https://github.com/darkk/redsocks
$ cd redsocks
$ make
```

此时，会在redsocks目录里生成可执行文件redsocks

## 3、拷贝到`/usr/bin`目录下

```
$ cp redsocks/redsocks /usr/bin/
```

## 4、创建配置文件

创建目录`/etc/redsocks`，创建文件`/var/log/redsocks/redsocks.log`

```
$ mkdir -p /etc/redsocks /var/log/redsocks
$ touch /var/log/redsocks/redsocks.log
```

然后创建配置文件`/etc/redsocks/redsocks.conf`，内容如下，

```
base {
        log_debug = off;
        log_info = on;
        log = "file:/var/log/redsocks/redsocks.log";
        daemon = off;
        redirector = iptables;
}
redsocks {
        local_ip = 127.0.0.1;
        local_port = 8881;
        ip = x.x.x.x;
        port = xx;
        type = socks5;
}
```

其中`local_port`表示redsocks在本机监听的端口，`ip`表示远程代理服务器的IP，`port`表示远程代理服务器的端口。

## 5、启动

执行以下命令启动

```
$ /usr/bin/redsocks -c /etc/redsocks/redsocks.conf &
```

## 6、添加代理规则

假设我们只想让目的地址为`10.142.0.0/16`的包走代理，那以，添加如下的iptables规则

```
$ iptables -t nat -A OUTPUT -d 10.142.0.0/16 -p tcp -j REDIRECT --to-ports 8881
```
