工作中用到代理服务器软件kingate，将相关内容加以简单总结，也参考了很多文章，也感谢各位前辈的贡献文档：

1、安装、配置 http://www.juyimeng.com/proxy-kingate-for-linux-install.html
2、指南 http://www.oschina.net/question/16_6372

wget http://jaist.dl.sourceforge.net/project/kingate/kingate/2.1/kingate-2.1.tar.gz
在RHEL 6中编译出现以下错误，(注：在RHEL 5.x中没有出现如下错误)
tar zxf kingate-2.1.tar.gz && cd kingate-2.1
./configure --prefix=/usr/local/kingate
make && make install
/usr/local/kingate/bin/kingate
[root@RHEL601 proxy]# tar zxf kingate-2.1.tar.gz
[root@RHEL601 proxy]# cd kingate-2.1
[root@RHEL601 kingate-2.1]# ./configure --prefix=/usr/local/kingate

错误：
1、[root@RHEL601 kingate-2.1]# make

解决方法：修改src/KDnsCache.cpp文件，头部添加 #include <string.h>
2、
mysocket.cpp: In member function ‘void mysocket::clear_recvq(int)’:
mysocket.cpp:478: error: ‘malloc’ was not declared in this scope

再次运行make && make install，正常。

(如果你想去掉socks4的功能，只支持socks5请做这一步，否则跳过)
vim ./src/socks.cpp
把
return create_socks4_connect(m_server);
替换为
goto cleanup;
应该是在第78行
保存退出VI
./configure --prefix=/usr/local/kingate
make
make install
/usr/local/kingate/bin/kingate(启动)
/usr/local/kingate/bin/kingate -q(关闭)
