ngrok是一个ddns服务，为内网机器绑定一个公网域名，方便开发调试远程接口(如微信开发)。
之前博文里面写过如何安装ngrok，但是由于公司里面的研发工程师的笔记本有windows本和mac本，所以本次主要讲怎么生成windows、mac客户端。
准备工作：需要参考http://nanchunle.blog.51cto.com/9244770/1710295，安装完成ngrok
一、编译Windwos客户端
cd /usr/local/go/src
GOOS=windows GOARCH=amd64 ./make.bash
cd /usr/local/ngrok
GOOS=windows GOARCH=amd64 make release-client
#同理，这里的amd64是64位系统，32位改成386
#应该会在 bin/windows_amd64 目录下生成ngrok客户端程序
到这里，编译就完成了，就可以将ngrok.exe下载到windows操作系统。
启动步骤：
1、将ngrok.exe放在D:\ngrok，并且在D:\ngrok编辑配置文件ngrok.cfg
| server_addr: "example.com:4443"
|
| ./ngrok -config=ngrok.cfg -log=ngrok.log -subdomain=test 8080 |
二、编译Mac客户端
cd /usr/local/go/src
GOOS=darwin GOARCH=amd64 ./make.bash
然后回去ngrok目录，接着编译：
cd /usr/local/src/ngrok
GOOS=darwin GOARCH=amd64 make release-client
完成后会在 /usr/local/src/ngrok/bin/darwin_amd64/ 下发现 ngrok 文件，将其拷贝到Mac上面，像上面windows
的设置即可使用。
三、注意事项
1、Centos/Linux下源码安装golang：

2、在步骤GOOS=darwin GOARCH=amd64 make release-client出现错误

解决方法：参考网站 http://stackoverflow.com/questions/27772831/golang-c-source-files-not-allowed-when-not-using-cgo
https://github.com/golang/go/wiki/InstallFromSource#introduction
IntroductionThis is a companion to http://golang.org/doc/install/source providing additional instructions for various operating systems. Install C toolsOn OS X, a C compiler is bundled in the command line tools for Xcode, and you don‘t need to install the whole Xcode to compile Go. If you have already installed Xcode 4.3+, you can install command line tools from the Components tab of the Downloads preferences panel. In more recent versions of Xcode, you can use On Ubuntu/Debian, use On RedHat/Centos 6, use On Windows, install |
