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 ``` ubuntu: ``` $ apt-get install libevent-dev 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; login = xxxx; # 如果不需要则删掉login与password两行 password = "xxxxx"; # 添加引号以防止密码有特殊字符 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 ``` ### **Reference** * https://github.com/darkk/redsocks * https://crosp.net/blog/administration/install-configure-redsocks-proxy-centos-linux/ * https://www.imzcy.cn/1560.html
