老叔教你亲手搭建一个Ngrok内网穿透服务器

智云科技 发布于 2022年9月21日 评论关闭 阅读(179)

最近公司需要开发公众号，在调试的时候就是个老大难问题，一般是需要内网穿透方式来让外网能够访问到本地的程序，提高我们的开发调试效率，一般大家会才用natapp、向日葵、ngrok等，这些都做得不错，但是你要用得好、用得舒心，还是得花钱，刚好我之前花了三百多块钱买了3年的云主机，所以就想着要不自己折腾一个ngrok吧，所以就有这个这篇文章

认识ngrok

这次我们需要用到ngrok这个东东，那么首先需要基本了解一下它是个啥？能干啥？ngrok是一款用Golang语言打造的开源的内网穿透软件，它可以帮助我们把内网的应用提供给外网用户访问。ngrok的开源地址是

搭建ngrok服务器

在搭建之前，我们需要准备两个东西：

  • 外网服务器
  • 域名 如果这两个没有的话，那就不好搞咯。这里我们先在服务器上安装好Golang的编译环境，由于我这边被墙了，所以就只有访问来下载了。

在go1.14.2.linux-amd64.tar.gz文件解压后会得到一个go文件，那么现在我们需要修改环境变量/etc/profile或者$HOME/.profile: 

 export GOROOT=你的解压目录/go
export PATH=$PATH:$GOROOT/bin

再source /etc/profile让配置文件即刻生效，这时候就可以看到我们的go命令是可执行的 

 [root@VM_175_142_centos go]# go version
go version go1.14.2 linux/amd64

现在，我们继续去github上下载ngrok源码 

 [root@VM_175_142_centos ngrok]# wget

把master.zip解压出来

进入到ngrok源码解压目录,并创建一个ssl目录,用于存放自定义证书 

 mkdir ssl&& cd ssl
export NGROK_DOMAIN="ngrok.52fx.biz"
openssl genrsa -out rootCA.key 2048
openssl req -x509 -new -nodes -key rootCA.key -subj "/CN=$NGROK_DOMAIN" -days 8888 -out rootCA.pem
openssl genrsa -out device.key 2048
openssl req -new -key device.key -subj "/CN=$NGROK_DOMAIN" -out device.csr
openssl x509 -req -in device.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out device.crt -days 8888

执行完上面的命令后，会得到这些文件: 

 [root@VM_175_142_centos ssl]# tree
.
|-- device.crt
|-- device.csr
|-- device.key
|-- rootCA.key
|-- rootCA.pem
`-- rootCA.srl

我们现在把这个文件复制到ngrok对应的目录并覆盖原文件 

 [root@VM_175_142_centos ssl]# cp rootCA.pem ../assets/client/tls/ngrokroot.crt
cp: overwrite ‘../assets/client/tls/ngrokroot.crt’? y
[root@VM_175_142_centos ssl]# cp device.crt ../assets/server/tls/snakeoil.crt
cp: overwrite ‘../assets/server/tls/snakeoil.crt’? y
[root@VM_175_142_centos ssl]# cp device.key ../assets/server/tls/snakeoil.key
cp: overwrite ‘../assets/server/tls/snakeoil.key’? y

现在我们就来开始编译ngrok 

 <!--linux服务端/客户端-->
GOOS=linux GOARCH=386 make release-server (32位)
GOOS=linux GOARCH=amd64 make release-server（64位）

GOOS=linux GOARCH=386 make release-client (32位)
GOOS=linux GOARCH=amd64 make release-client（64位）

<!--Mac OS服务端/客户端-->
GOOS=darwin GOARCH=386 make release-server
GOOS=darwin GOARCH=amd64 make release-server

GOOS=darwin GOARCH=386 make release-client
GOOS=darwin GOARCH=amd64 make release-client


<!--windows服务端/客户端-->
GOOS=windows GOARCH=386 make release-server
GOOS=windows GOARCH=amd64 make release-server

GOOS=windows GOARCH=386 make release-client
GOOS=windows GOARCH=amd64 make release-client

,我们先编译一个linux运行的服务端 

 [root@VM_175_142_centos ngrok-master]# export GOOS=linux
[root@VM_175_142_centos ngrok-master]# export GOARCH=amd64
[root@VM_175_142_centos ngrok-master]# make release-server
bin/go-bindata -nomemcopy -pkg=assets -tags=release \

        -debug=false \
        -o=src/ngrok/server/assets/assets_release.go \

go install -tags 'release' ngrok/main/ngrokd

第一次执行命令时会下载包，所以会比较花时间，可以通过在环境变量中加入GOPROXY值为的方式来添加代理。我继续编译一个windows 64的客户端 

 [root@VM_175_142_centos ngrok-master]# export GOOS=windows
[root@VM_175_142_centos ngrok-master]# export GOARCH=amd64
[root@VM_175_142_centos ngrok-master]# make release-client
bin/go-bindata -nomemcopy -pkg=assets -tags=release \
        -debug=false \
        -o=src/ngrok/client/assets/assets_release.go \
        assets/client/...
bin/go-bindata -nomemcopy -pkg=assets -tags=release \
        -debug=false \
        -o=src/ngrok/server/assets/assets_release.go \
        assets/server/...
go get -tags 'release' -d -v ngrok/...
go install -tags 'release' ngrok/main/ngrok

现在，我们可以在bin目录下看到这些文件 

 [root@VM_175_142_centos bin]# tree
.
|-- go-bindata
|-- ngrokd
`-- windows_amd64
    `-- ngrok.exe

先把服务端运行起来，默认情况下ngrok是占用的80和443端口，我们可以自行配置 

 [root@VM_175_142_centos bin]# ./ngrokd -domain="ngrok.52fx.biz" -httpAddr=":8888" -httpsAddr=":8433"
[14:08:59 CST 2020/04/23] [INFO] (ngrok/log.(*PrefixLogger).Info:83) [registry] [tun] No affinity cache specified
[14:08:59 CST 2020/04/23] [INFO] (ngrok/log.Info:112) Listening for public http connections on [::]:8888
[14:08:59 CST 2020/04/23] [INFO] (ngrok/log.Info:112) Listening for public https connections on [::]:8433
[14:08:59 CST 2020/04/23] [INFO] (ngrok/log.Info:112) Listening for control and proxy connections on [::]:4443
[14:08:59 CST 2020/04/23] [INFO] (ngrok/log.(*PrefixLogger).Info:83) [metrics] Reporting every 30 seconds

现在，我们新建一个客户端配置文件ngrok.cfg 

 <!--配置服务端连接地址，也就是基础域名。端口则与服务端-tunnelAddr配置相同-->
server_addr: "ngrok.52fx.biz:4443"  
trust_host_root_certs: false

现在就可以在客户端运行代理了，ngrok -config=ngrok.cfg -subdomain 域名 端口 ，如ngrok -config=ngrok.cfg -subdomain weixin 8080 执行完成之后会看到这样的界面

这里我们还需要配置域名,切记，需要配置两条

  • ngrok.52fx.biz-> xxx.xx.xxx.xxx(外网IP)
  • *.ngrok.52fx.biz-> xxx.xx.xxx.xxx(外网IP) 该记录为泛解析，就是这样的域名都会解析到指定的ip然后再转发 现在我们来访问一下看是否正常 ok,就是这么回事。但是呢，我们这里的端口是8888，每次访问还得在域名后面加端口，真的是太不优雅了，所以得想办法处理。因为我之前的80端口被nginx给占用了，所以，我们这里再来转发一次吧。 
 server {
        listen       80;
        server_name  *.ngrok.52fx.biz;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
             proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                        proxy_set_header X-Nginx-Proxy true;
                        proxy_set_header Connection "";
                        proxy_pass       #这里的weixin可以改为任意名称，因为是泛解析
        }
        
          location ~ .*\.(js|css)$ {            
             proxy_pass       #这里的weixin可以改为任意名称，因为是泛解析

         }

      
    }

这样看起来是不是更友好一些了呢?如果你的ngrok是监听的80端口，大可不必这样麻烦。
