ngrok实现内网映射和反向代理

安装gcc

yum install gcc

安装git

yum install git

安装GO语言环境

yum install go

go version

下载ngrok源码

cd /usr/local/src

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

openssl genrsa -out rootCA.key 2048

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

openssl genrsa -out device.key 2048

openssl req -new -key device.key -subj "/CN=flask.huchangyi.com" -out device.csr

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

将新生成的证书，替换掉assets/client/tls下的证书

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

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

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

编译生成ngrokd（服务端）

#这里是交叉编译，linux系统GOOS=linux,64位系统GOARCH=amd64，32位系统GOARCH=386

#当前系统可用go env查看

GOOS=linux GOARCH=amd64 make release-server

启动服务端(/usr/local/src/ngrok目录下) 

nohup /usr/local/src/ngrok/bin/ngrokd -tlsKey="assets/server/tls/snakeoil.key" -tlsCrt="assets/server/tls/snakeoil.crt" -domain="flask.huchangyi.com"  -httpAddr=":8081" -httpsAddr=":8082" -tunnelAddr=":8083" &

添加新的域名解析

*.flask

编译生成ngrok（客户端）

linux版客户端： make release-client

windows客户端32位： GOOS=windows GOARCH=386 make release-client

windows客户端64位： GOOS=windows GOARCH=amd64 make release-client

MAC: GOOS=darwin GOARCH=amd64 make release-client

客户端执行

nohup /home/ngrok/bin/ngrok -config /home/ngrok/bin/ngrok.cfg -proto tcp 22 &

nohup /home/ngrok/bin/ngrok -subdomain rasp -config /home/ngrok/bin/ngrok.cfg 80 &

或者

nohup /home/ngrok/bin/ngrok -subdomain rasp -config /home/ngrok/bin/ngrok.cfg start http https ssh

配置文件格式（ngrok.cfg）

server_addr: "flask.huchangyi.com:8083"

trust_host_root_certs: false

tunnels:

  http:

    subdomain: "www"

    proto:

      http: "8090"

      

  https:

    subdomain: "www"

    proto:

      https: "8091"

 

  ssh:

    remote_port: 3333

    proto:

      tcp: "22"

编译树莓派上的ngrok客户端

将刚才用来编译ngrok服务端的ngrok源码文件夹全部复制到树莓派上： 

cd ./ngrok 

make release-client 

出错时

把源码目录下bin/go-bindata删除，然后执行make release-client

直接下载已经编译好的

wget http://huchangyi.com/doc/ngrok-rasp.zip

unzip ngrok-rasp.zip

mv ngrok-rasp ngrok

vim /etc/rc.local

bash /home/ngrok/start-ngrok.sh
