前言
好吧,我承认这个跟树莓派没有半毛关系,但是为了以后众多内网应用可以被访问,还是想强行发生一波关系。
软硬清单
- 云服务器一枚
- 备案域名一枚
- 开源 Nginx、Dcoker、Ngrok
服务配置
├── build.sh
├── docker-compose.yml
├── Dockerfile
└── server.sh
Dockerfile配置,源码中 git 地址有些问题,导致部分客户端没有生成,这里替换掉了:
FROM golang:1.7.1-alpine

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

ENV HTTP_ADDR :80
ENV HTTPS_ADDR :443
EXPOSE 4443
EXPOSE 80
EXPOSE 443
CMD /bin/sh
build.sh 配置:
#!/bin/sh
set -e
if [ "${DOMAIN}" == "**None**" ]; then
echo "Please set DOMAIN"
exit 1
fi
cd ${MY_FILES}
if [ ! -f "${MY_FILES}/base.pem" ]; then
openssl genrsa -out base.key 2048
openssl req -new -x509 -nodes -key base.key -days 10000 -subj "/CN=${DOMAIN}" -out base.pem

cp -r base.pem /ngrok/assets/client/tls/ngrokroot.crt

cp -r /ngrok/bin ${MY_FILES}/bin
echo "build ok !"
server.sh 配置:
#!/bin/sh
set -e
if [ "${DOMAIN}" == "**None**" ]; then
echo "Please set DOMAIN"
exit 1
fi
if [ ! -f "${MY_FILES}/bin/ngrokd" ]; then
echo "ngrokd is not build,will be build it now..."
/bin/sh /build.sh
fi
${MY_FILES}/bin/ngrokd -tlsKey=${MY_FILES}/device.key -tlsCrt=${MY_FILES}/device.crt -domain="${DOMAIN}" -httpAddr=${HTTP_ADDR} -httpsAddr=${HTTPS_ADDR} -tunnelAddr=${TUNNEL_ADDR}
docker-compose.yml 配置:
server:
image: hteen/ngrok
ports:
- "8082:80"
- "4432:443"
- "4443:4443"
volumes:
- /data/ngrok:/myfiles
environment:
- DOMAIN="tunnel.hteen.cn"
command: /bin/sh /server.sh
然后,构建镜像:
docker build -t hteen/ngrok .
启动
- 我们需要挂载宿机目录(E.g /data/ngrok)到容器的/myfiles目录
- 第一次运行,它将会在/data/ngrok目录下生成二进制文件和CA证书
sudo docker run --rm -it -e DOMAIN="ngrok.52itstyle.vip" -v /data/ngrok:/myfiles hteen/ngrok /bin/sh /build.sh
安装成功会出现以下提示(省略中间过程):
Generating RSA private key, 2048 bit long modulus
.............................+++
.............................+++
e is 65537 (0x10001)
Generating RSA private key, 2048 bit long modulus
...............................+++
...............................+++
go get -tags 'release' -d -v ngrok/...
go install -tags 'release' ngrok/main/ngrok
build ok !
客户端和服务端生成在/data/ngrok/bin目录下:
├── darwin_386
│ └── ngrok
├── darwin_amd64
│ └── ngrok
├── go-bindata
├── linux_386
│ └── ngrok
├── linux_arm
│ └── ngrok
├── ngrok
├── ngrokd
├── windows_386
│ └── ngrok.exe
└── windows_amd64
└── ngrok.exe
启动Ngrok server
由于ngrok默认使用80和443端口,这里我们使用Nginx服务做转发,通过端口映射的方式访问Docker容器(参考docker-compose.yml配置)。
docker run -idt --name ngrok-server \
-v /data/ngrok:/myfiles \
-p 8082:80 \
-p 4432:443 \
-p 4443:4443 \
-e DOMAIN='ngrok.52itstyle.com' hteen/ngrok /bin/sh /server.sh
启动之后需要在nginx.conf 添加两条反向代理配置(HTTPS请求自行配置):
server {
listen 80;
server_name ngrok.52itstyle.vip *.ngrok.52itstyle.vip;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8082;
}
}
配置DNS解析
服务启动后,要想正常运行,我们还需要添加两条A记录到云服务器(替换成自己的IP地址):
启动Ngrok client
首先从data/ngrok/bin目录下载各个环境下的客户端。
windows 测试
首先创建一个 ngrok.yml 配置文件:
server_addr: "ngrok.52itstyle.vip:4443"
trust_host_root_certs: false
tunnels:
doc:
proto:
http: "8080"
auth: "admin:admin" # 访问账号密码
owncloud:
proto:
http: "8081"
使用cmd命令切换到对应的目录下,然后执行以下命令:
ngrok.exe -config=ngrok.yml start doc # 启动单个服务
ngrok.exe -config=ngrok.yml start-all #启动所有服务
如果出现以下界面,说明安装成功:
Tunnel Status online
Version 1.7/1.7
Forwarding http://doc.ngrok.52itstyle.vip -> 127.0.0.1:8080
Web Interface 127.0.0.1:4040
# Conn 0
Avg Conn Time 0.00ms
注意事项
- 防火墙需要开放4443端口,否则是无法连接成功的
