下载编译好的客户端/服务端

（2017年07月18日更新）

发现自己编译的客户端跑在mac Sierra系统出现问题,暂时没有解决,这里下载编译好的客户端/服务端文件

http://www.ittun.com/apply.html

服务端启动命令

例子:

./ngrokd -domain="ngrok.xxx.com"  -httpAddr=":8080" -httpsAddr=":8087" -tunnelAddr=":4443"

后台一直执行:

nohup bin/ngrokd -domain="ngrok.xxx.com" -httpAddr=":8080"  -httpsAddr=":8087" -tunnelAddr=":44443" &

客户端配置

客户端配置过程不变

自己编译客户端

安装git、golang

安装git

安装依赖工具:

# 安装依赖
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
yum install  gcc perl-ExtUtils-MakeMaker

# 删除已有 git
yum remove git

# 下载源码
cd /usr/src
wget -c wget -c https://github.com/git/git/archive/v2.13.3.tar.gz git-v2.13.3.tar.gz
tar xzf git-v2.13.3.tar.gz

# 编译安装
cd git-2.13.3
make prefix=/usr/local/git all
make prefix=/usr/local/git install
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc

查看版本

[root@iZ2ze147skj2icrqqx7nhzZ ~]# git --version
git version 2.13.3

安装golang

yum install golang

查看版本:

# go version
go version go1.6.3 linux/amd64

go env 查看环境变量:

[root@iZ2ze147skj2icrqqx7nhzZ ~]# go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH=""
GORACE=""
GOROOT="/usr/lib/golang"
GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64"
GO15VENDOREXPERIMENT="1"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"

配置ngrok

1). clone到本地

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

2). 配置环境变量

export NGROK_DOMAIN="tunnel.mydomain.com"

tunnel.mydomain.com替换成你自己的域名。

4). 生成自签名ssl证书

cd ngrok

openssl genrsa -out rootCA.key 2048

openssl req -x509 -new -nodes -key rootCA.key -subj "/CN=$NGROK_DOMAIN" -days 5000 -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 5000

cp rootCA.pem assets/client/tls/ngrokroot.crt
cp device.crt assets/server/tls/snakeoil.crt
cp device.key assets/server/tls/snakeoil.key

编译服务端

路径以实际安装路径为准

从go env可以看到我的GOROOT GOROOT="/usr/lib/golang"

cd /usr/lib/golang/src
GOOS=linux GOARCH=amd64 ./make.bash #(64位)    

cd ~/ngrok/
GOOS=linux GOARCH=386 make release-server   #(32 )
GOOS=linux GOARCH=amd64 make release-server #（64位）

结果会在ngork/bin下生成ngrokd文件。还有一个go-bindata文件。

编译客户端

要生成对应平台的客户端程序，需要继续进行交叉编译。

路径以实际安装路径为准

Linux

#如果是32位系统把amd64改成386

cd /usr/lib/golang/src
GOOS=linux GOARCH=amd64 ./make.bash #(64位)    

cd ~/ngrok/
GOOS=linux GOARCH=amd64 make release-client #（64位） 生成`linux_386`文件

macOS

# MAC OS 64位操作系统（32位系统把amd64改成386）

cd /usr/lib/golang/src
GOOS=darwin GOARCH=amd64 ./make.bash   

cd ~/ngrok/
GOOS=darwin GOARCH=amd64 make release-client  #（64位） 生成`darwin_amd64`文件

windows

# Windows 64位操作系统（32位系统把amd64改成386）

cd /usr/lib/golang/src
GOOS=windows GOARCH=amd64 ./make.bash
cd ~/ngrok/
GOOS=windows GOARCH=amd64 make release-client

运行

启动服务端

cd ~/ngrok/bin
#以8080端口为例
#请将`tunnel.mydomain.com`替换成自己的域名
./ngrokd -domain="tunnel.mydomain.com" -httpAddr=":8080"

#完整的参数
./ngrokd -domain="tunnel.mydomain.com" -httpAddr=":8080" -httpsAddr=":443" -tunnelAddr=":4443"

./ngrokd -domain="tunnel.tyrad.cc" -httpAddr=":8080" -httpsAddr=":8087"

访问: https://tunnel.mydomain.com:8080,如果发现Tunnel tunnel.mydomain.com not found 说明启动成功

后台一直执行:

nohup bin/ngrokd -domain="tunnel.mydomain.com" -httpAddr=":8080" &

nohup ./ngrokd -domain="tunnel.tyrad.cc" -httpAddr=":8080" -httpsAddr=":8087" &

杀死:

ps -A   #找到ngrokd的PID  
kill xxx

启动客户端

下载客户端,以macOS为例,需要下载~/ngork/bin/darwin_amd64/ngrok文件。

修改ngrok文件的权限:

chmod +x ngrok

创建文件ngrok.cfg,并编辑内容为(tunnel.mydomain.com替换成自己的域名):

server_addr: "tunnel.mydomain.com:4443"
trust_host_root_certs: false

并将ngrok和ngrok.cfg放到同一个文件夹下。

启动(xx是随便输入,相当于三级域名了):

./ngrok -config=ngrok.cfg -subdomain xxx  80

可以看到启动成功:

错误分析

编译报错:

执行GOOS=linux GOARCH=amd64 ./make.bash之类的操作报错:

[root@iZ2ze147skj2icrqqx7nhzZ src]# GOOS=darwin GOARCH=amd64 ./make.bash
##### Building Go bootstrap tool.
cmd/dist
ERROR: Cannot find /root/go1.4/bin/_/go.
ERROR: or /root/go1.4/bin/_/go.
Set $GOROOT_BOOTSTRAP to a working Go tree >= Go 1.4.

原因:

https://github.com/northbright/Notes/blob/master/Golang/china/install-go1.6-from-source-on-centos7-in-china.md Go1.5+的编译过程需要Go1.4的二进来实现 bootstrap（自举）(简单来说: Go需要Go自身来编译)。

解决方法:

#clone到家目录
git clone https://github.com/golang/go.git ~/go1.4
#切换分支
git checkout -b 1.4.3 go1.4.3
cd src
./all.bash

操作完成,再重新尝试。

可能与服务器80、443端口冲突的问题

可以使用其他端口:

./ngrokd -domain="tunnel.tyrad.cc" -httpAddr=":8080" -httpsAddr=":8087"

几处参考

可以采用docker https://fengqi.me/unix/409.html

隔一段时间自动断连接?

问题:

微信的80端口和apache的冲突
apache 443端口冲突,必须要关闭apache?
