开始使用
1. 下载
2. 解压并安装
$ unzip <下载保存路径>/ngrok.zip
3. 创建ngrok账号并配置authtoken
由于使用 ngrok 需要生成映射的动态域名，因此官网使用用户的形式来进行控制和跟踪，所以你需要注册一个账户并通过凭证来使用它。
# 保存你的凭证
$ ./ngrok authtoken <authtoken>
4. 开始穿透内网
# 映射 HTTP 80 端口进行测试
$ ./ngrok http 80

已经开启成功，外网直接访问：http://bee9c9ff.ngrok.io 或 https https://bee9c9ff.ngrok.io ，即可访问到你的站点。
或你想穿透某一端口，如：TCP，你可以这样来使用
# 映射 TCP 9000 端口进行测试
$ ./ngrok tcp 9000

NAME:

ngrok exposes local networked services behinds NATs and firewalls to the
public internet over a secure tunnel. Share local websites, build/test

ngrok http 80 # secure public URL for port 80 web server
ngrok http -subdomain=baz 8080 # port 8080 available at baz.ngrok.io
ngrok http foo.dev:80 # tunnel to host:port instead of localhost
ngrok tcp 22 # tunnel arbitrary TCP traffic to port 22
ngrok tls -hostname=foo.com 443 # TLS traffic for foo.com to port 443
ngrok start foo bar baz # start tunnels from the configuration file
