编译ngrok的Windows、Mac的客户端

    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" trust_host_root_certs: false

2.打开windows控制台win+r ,进入D:\ngrok，执行

./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：

wget https: //storage .googleapis.com /golang/go1 .4.1.linux-amd64. tar .gz tar -C  /usr/local -xzf go1.4.1.linux-amd64. tar .gz mkdir $HOME /go echo 'export GOROOT=/usr/local/go' >> ~/.bashrc echo 'export GOPATH=$HOME/go' >> ~/.bashrc echo 'export PATH=$PATH:$GOROOT/bin:$GOPATH/bin' >> ~/.bashrc source $HOME/.bashrc

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

imports runtime: C source files not allowed when not using cgo or SWIG: atomic_amd64x.c defs.c float.c heapdump.c lfstack.c malloc.c mcache.c mcentral.c mem_darwin.c mfixalloc.c mgc0.c mheap.c msize.c os_darwin.c panic.c parfor.c proc.c runtime.c signal.c signal_amd64x.c signal_unix.c stack.c string.c sys_x86.c make: *** [deps] Error 1

Introduction This is a companion to http://golang.org/doc/install/source providing additional instructions for various operating systems. Install C tools On 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  xcode-select --install  command to install the command line tools without opening Xcode. To verify you have a working compiler, just invoke  gcc  in a freshly created Terminal window, unless you see the  "gcc: command not found"  error, you are ready to go. On Ubuntu/Debian, use  sudo apt-get install gcc libc6-dev . If you want to build 32-bit binaries on a 64-bit system you'll also need the  libc6-dev-i386  package. On RedHat/Centos 6, use  sudo yum install gcc glibc-devel . If you want to build 32-bit binaries on a 64-bit system you'll need both  glibc-devel.i386  and  glibc-devel.x86_64  packages.
