1. ngrok安装配置

1.1. 安装环境

检测 gcc 和 git 是否已安装（用于下载ngrok源码）

[root@server-test-211 home]# gcc -v

[root@server-test-211 home]# git -v

如果没有安装，则进行安装

[root@server-test-211 home]# yum install gcc -y

[root@server-test-211 home]# yum install git -y

1.2. 安装 go 语言环境

安装golang

1.3. 在服务器搭建ngrok服务

1. 下载ngrok源码

    [root@server-test-211 server]# git clone https://github.com/inconshreveable/ngrok.git
   

2. 生成证书

    [root@server-test-211 server]# cd ngrok
   

   配置域名：

    [root@server-test-211 ngrok]# export NGROK_DOMAIN="tunnel.ob.me"
   
    [root@server-test-211 ngrok]# openssl genrsa -out base.key 2048
   
    [root@server-test-211 ngrok]# openssl req -x509 -new -nodes -key base.key -subj "/CN=$NGROK_DOMAIN" -days 5000 -out base.pem
   
    [root@server-test-211 ngrok]# openssl genrsa -out server.key 2048
   
    [root@server-test-211 ngrok]# openssl req -new -key server.key -subj "/CN=$NGROK_DOMAIN" -out server.csr
   
    [root@server-test-211 ngrok]# openssl x509 -req -in server.csr -CA base.pem -CAkey base.key -CAcreateserial -out server.crt -days 5000
   

3. 将新生成的证书替换，每条指令执行完后执行 y并回车 ```bash [root@server-test-211 ngrok]# cp base.pem assets/client/tls/ngrokroot.crt

   [root@server-test-211 ngrok]# cp server.crt assets/server/tls/snakeoil.crt

   [root@server-test-211 ngrok]# cp server.key assets/server/tls/snakeoil.key

4. 编译生成 `ngrokd` （服务端）
   ```bash
    [root@server-test-211 ngrok]# GOOS=linux GOARCH=amd64 make release-server
    GOOS="" GOARCH="" go get github.com/jteeuwen/go-bindata/go-bindata
    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/ngrokd
    go install -tags 'release' ngrok/main/ngrok

或者服务端、客户端一起生成

    [root@server-test-211 ngrok]# make release-server release-client

生成在 ~/ngrok/bin/目录中

如果 GOOS=linux GOARCH=amd64 无法设置 go 配置信息，可执行以下指令

    [root@server-test-211 ngrok]# export GOOS=linux
    [root@server-test-211 ngrok]# export GOARCH=amd64

然后通过go env查看配置信息

    [root@server-test-211 ngrok]# go env
    GOARCH="amd64"
    GOBIN=""
    GOCACHE="/root/.cache/go-build"
    GOEXE=""
    GOFLAGS=""
    GOHOSTARCH="amd64"
    GOHOSTOS="linux"
    GOOS="linux"
    GOPATH="/home/kz/ngrok"
    GOPROXY=""
    GORACE=""
    GOROOT="/usr/local/go"
    GOTMPDIR=""
    GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
    GCCGO="gccgo"
    CC="gcc"
    CXX="g++"
    CGO_ENABLED="1"
    GOMOD=""
    CGO_CFLAGS="-g -O2"
    CGO_CPPFLAGS=""
    CGO_CXXFLAGS="-g -O2"
    CGO_FFLAGS="-g -O2"
    CGO_LDFLAGS="-g -O2"
    PKG_CONFIG="pkg-config"
    GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build668421739=/tmp/go-build"

1. 编译生成 ngrok （客户端）

    [root@server-test-211 ngrok]# GOOS=windows GOARCH=amd64 make release-client
   

   生成在~/ngrok/bin/windows_amd64/目录中

    -rwxr-xr-x. 1 root root  2893387 May  6 10:11 go-bindata
    -rwxr-xr-x. 1 root root 12953899 May  6 10:11 ngrok
    -rwxr-xr-x. 1 root root 10271251 May  6 10:11 ngrokd
   

2. 设置域名解析

3. 运行 Ngrok

    [root@server-test-211 ngrok]# ./bin/ngrokd -tlsKey=server.key -tlsCrt=server.crt -domain="tunnel.ob.me" -httpAddr=":9000" -httpsAddr=":9001"
    [10:27:01 CST 2019/05/06] [INFO] (ngrok/log.(*PrefixLogger).Info:83) [metrics] Reporting every 30 seconds
    [10:27:01 CST 2019/05/06] [INFO] (ngrok/log.(*PrefixLogger).Info:83) [registry] [tun] No affinity cache specified
    [10:27:01 CST 2019/05/06] [INFO] (ngrok/log.Info:112) Listening for public http connections on [::]:9000
    [10:27:01 CST 2019/05/06] [INFO] (ngrok/log.Info:112) Listening for public https connections on [::]:9001
    [10:27:01 CST 2019/05/06] [INFO] (ngrok/log.Info:112) Listening for control and proxy connections on [::]:4443
   

   服务端启动(后台运行)：

    [root@server-test-211 ngrok]# nohup ngrokd -domain="tunnel.ob.me" -httpAddr=":9000" &
   

4. 开机自动启动ngrok服务

    [root@server-test-211 ~]# vi /etc/init.d/ngrok_start
    # 加入下面内容
    cd /home/kezai/ngrok/
    ./bin/ngrokd -tlsKey=server.key -tlsCrt=server.crt -domain="tunnel.ob.me" -httpAddr=":9000" -httpsAddr=":9001"
    chmod 755 /etc/init.d/ngrok_start
