安装 stun/turn服务

1，关于stun和turn

STUN（Simple Traversal of UDP over NATs，NAT 的UDP简单穿越）是一种网络协议，它允许位于NAT（或多重NAT）后的客户端找出自己的公网地址，查出自己位于哪种类型的NAT之后以及NAT为某一 个本地端口所绑定的Internet端端口。这些信息被用来在两个同时处于NAT 路由器之后的主机之间建立UDP通信。该协议由RFC 3489定义。目前RFC 3489协议已被RFC 5389协议所取代，新的协议中，将STUN定义为一个协助穿越NAT的工具，并不独立提供穿越的解决方案。它还有升级版本RFC 7350，目前正在完善中。

TURN的全称为Traversal Using Relay NAT，即通过Relay方式穿越NAT，TURN应用模型通过分配TURNServer的地址和端口作为客户端对外的接受地址和端口，即私网用户发出的报文都要经过TURNServer进行Relay转发。

在根目录创建一个user.db文件 
使用turnserver启动：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">turnserver --userdb /root/turnuser<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.db</span> 
里面是webrtc用户名密码：
<span class="hljs-label" style="box-sizing: border-box;">webrtc:</span>secret</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

安装node参考之前文章：

修改main.js

将stun服务器和turn服务器替换。

stun和trun是webrtc打通的关键服务器，但是资源有限没有在公网测试。
