一、安装ngrok编译环境

1、安装git所需要的依赖包 

 yum -y install zlib-devel openssl-devel perl hg cpio expat-devel gettext-devel curl curl-devel perl-ExtUtils-MakeMaker hg wget gcc gcc-c++ libxslt xmlto

   yum -y install asciidoc

2、卸载系统自带git，除非版本高于1.8

git version

Git yum remove git 

3、安装git

yum install git

4、安装go环境

yum install y golang

检查go环境

go version

二、安装ngrok

1、下载ngrok源码

cd /usr/local/

git clone https://github.com/inconshreveable/ngrok.git

2、安装证书

cd ngrok

openssl genrsa -out rootCA.key 2048

openssl req -x509 -new -nodes -key rootCA.key -subj "/CN=example.com" -days 5000 -out rootCA.pem

openssl genrsa -out device.key 2048

openssl req -new -key service.key -subj "/CN=example.com" -out device.csr

openssl x509 -req -in service.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out device.crt -days 5000

3、证书拷贝

yes|cp rootCA.pem assets/client/tls/ngrokroot.crt

yes|cp service.crt assets/server/tls/snakeoil.crt

yes|cp service.key assets/server/tls/snakeoil.key

4、交叉编译

centos服务端：

GOOS=linux GOARCH=amd64

make release-server

windows客户端：

GOOS=windows GOARCH=amd64

make release-client

5、启动服务端

ngrok/bin目录下，可以改变4443端口为其他比如8899：

./ngrokd -domain="example.com" -tunnelAddr=":8899"

后台运行服务端：

setsid ./ngrokd -domain="example.com" -tunnelAddr=":8899"

或者：

 yum install screen

scree -S keepngrok

./ngrokd -domain="example.com" -tunnelAddr=":8899"

6、客户端使用

新建一个ngrok.cfg

server_addr: "example.com:8899"

trust_host_root_certs: false

tunnels:

  http:

    subdomain: "dev"

    proto:

      http: "8090"

  https:

    subdomain: "test"

    proto:

      https: "8091

  ssh:

    remote_port: 3311

    proto:

      tcp: "22"

进入客户端目录启动

cd e:\windows_amd64

ngrok -config ngrok.cfg start http https ssh
