webrtc起步 － apprtc服务器搭建

简介
     apprtc 是什么，webrtc.org官方指定体验app
 
 
原料：
ubuntu14.04，其他linux版本不限，官方并没特殊说明
chrome M51＋
 
 
 
步骤：
 
设置代理
由于国内网络的特殊性，这步非常关键，如果没有靠谱的代理，很可能以失败告终。
设置shell环境的代理
添加如下内容到 ~/.bashrc
export http_proxy=http://10.xx.xx.xx:100
export https_proxy=http://10.xx.xx.xx:100
     
设置git的代理
添加如下内容到  ~/.gitconfig
[http]
         proxy = http://10.xx.xx.xx:100
         sslverify = false
[https]
          proxy = http://10.xx.xx.xx:100
 
 
下载，解压.

安装npm
下面摘录自［1］，如果设置好代理之后，这些步骤可很顺利的完成
 
Install grunt by first installing npm. npm is distributed as part of nodejs.
sudo apt-get install nodejs
sudo npm install -g npm
 
On Ubuntu 14.04 the default packages installs /usr/bin/nodejs but the /usr/bin/node executable is required for grunt. This is installed on some Ubuntu package sets; if it is missing, you can add this by installing the nodejs-legacypackage,
sudo apt-get install nodejs-legacy
 
It is easiest to install a shared version of grunt-cli from npm using the -g flag. This will allow you access the gruntcommand from /usr/local/bin. More information can be found on gruntjs Getting Started.
sudo npm -g install grunt-cli

Omitting the -g flag will install grunt-cli to the current directory under the node_modules directory.

 
Finally, you will want to install grunt and required grunt dependencies. This can be done from any directory under your checkout of the webrtc/apprtc repository.
npm install

On Ubuntu, you will also need to install the webtest package:

sudo apt-get install python-webtest
 
编译apprtc
sudo grunt build --force
每次更新修改代码都应该重新编译，编译生成的文件存放在out目录中
 
 
运行apprtc
sudo ../google_appengine//dev_appserver.py ./out/app_engine --host 0.0.0.0
 
 
安装 rfc5766-turn-server 
sudo app-get install rfc5766-turn-server
配置
编辑 /etc/trunserver.conf
确保打开了以下行的注释，并且赋予正确的值，port，ip的值当然要按照实际情况填写，static-auth-secret=4080218913最好也不要修改成其他值，因为apprtc硬编码了这个值，除非你也去修改apprtc里对应的地方。realm=cn.cn 这个没有要求，填写自己的域名即可。Verbose 不是必须的，打开它只是为了可以看到更多输出而已。
 
18:listening-port=9000
52:listening-ip=10.58.60.236
97:relay-ip=10.58.60.236
154:Verbose
203:use-auth-secret
211:static-auth-secret=4080218913
289:realm=cn.cn
446:
 
 
制作证书
➜  apprtc git:(restapi) ✗ openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 99999 -nodes
Generating a 2048 bit RSA private key
..............+++
....................................................+++
writing new private key to 'key.pem'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:cn
State or Province Name (full name) [Some-State]:cn
Locality Name (eg, city) []:cn
Organization Name (eg, company) [Internet Widgits Pty Ltd]:cn
Organizational Unit Name (eg, section) []:cn
Common Name (e.g. server FQDN or YOUR name) []:cn
Email Address []:cn
 
生成过程中多次提示输入一些信息，可以马马虎虎填写一下。
 
将生成的 cert.pem 和 key.pem 安装到/cert/目录下，为什么要放在这个目录呢，因为collidermain中硬编码读取下面两个文件。不放在这里就意味着要去修改collidermain中的代码，为了省事，暂且顺着它的方式来。
"/cert/cert.pem"
"/cert/key.pem"
 
 
 
安装 stunnle
sudo app-get install stunnle
配置
编辑 /usr/local/etc/stunnel/stunnel.conf
 
添加以下内容
[apprtc_main]
accept  = 443
connect = 8080
cert = /cert/cert.pem
 
[apprtc_auth]
accept  = 4431
connect = 8081
cert = /cert/cert.pem
 
 
安装golang
sudo app-get install golang
 
 
编译信令
在apprtc目录中
export GOPATH=$(shell pwd)
go build -o collidermain src/collider/collidermain/main.go
 
编译rfc5766-turn-server授权服务：apprtc_turn_auth
授权服务笔者没有找到源码，所以需要自己写，这里共享出笔者写golang版的代码。
编译方式如下
export GOPATH=$(shell pwd)
go build -o auth auth.go
 
 
 
 
修改apprtc中的代码
对apprtc/src做如下修改，但是IP地址要根据实际情况填写。修改之后必不可少的步骤是重新编译，千万别忘了。

最后
由于整个过程过于繁琐，笔者在实验过程中写了Makefile，现也共享传来。这个Makefile在调试运行过程中缺失带来了很多便利，不用每次噼里啪啦的敲一堆命令。几乎包含了上述所有编译，运行的操作，有了此文件只需make  xxx 就行
