coTurn 运行在Windows平台的方法
coTurn是一个开源的STUN和TURN及ICE服务项目，只是不支持Windows。
为了在window平台上使用coTurn源码，需要在windows平台下安装Cygwin环境，并编译coTurn源码，使其可以运行在windows平台上。
步骤：
1、安装Cygwin，地址：https://cygwin.com/install.html，按照其说明进行安装。参照说明地址：https://cygwin.com/cygwin-ug-net/cygwin-ug-net.html
最好选择64位的，我一开始用的32位的，安装gcc总是报错，换到64位就可以了（也许是我机子问题）。
安装过程中选择的镜像源地址，为了更加快速，使用http://mirrors.163.com/cygwin/
这里有几个坑，要注意，不然编译的时候 会报错：
在这个页面，要在del列表下选择四个工具库：
①gcc
②openssl
③libevent
④make（bin和source都要选择）
2、下载coTurn源码。目前Release最新版本的地址为：https://codeload.github.com/coturn/coturn/zip/4.5.0.4
解压后，把coturn-4.5.0.4文件夹放在cygwin的安装路劲C:\cygwin64\bin下。后面就开始编译了。
3、编译:
编译过程：
①生成Makefile文件
CC=gcc ./configure Dev@Dev-PC /bin/coturn-4.5.0.4
$ CC=gcc ./configure
install 是 /usr/bin/install
pkill 是 /usr/bin/pkill
sqlite3 是 /usr/bin/sqlite3
Use TMP dir /var/tmp
Compiler: gcc
Library option -lsocket cannot be used
CYGWIN ?
Library option -lwldap64 cannot be used
Library option -lnsl cannot be used
Sockets code is fine: no sin_len field present

MONGODB DEVELOPMENT LIBRARIES (libmongoc-1.0 and libbson-1.0) AND/OR HEADER (mongoc.h)

THAT'S OK BUT THE TURN SERVER IS BUILDING WITHOUT MONGODB SUPPORT.

THAT'S OK BUT THE TURN SERVER IS BUILDING WITHOUT REDIS SUPPORT.

==================================================================
1) If you system supports automatic start-up system daemon services,
the, to enable the turnserver as an automatically started system
service, you have to:
a) Create and edit /etc/turnserver.conf or
/usr/local/etc/turnserver.conf .
Use /usr/local/etc/turnserver.conf.default as an example.
b) For user accounts settings: set up SQLite or PostgreSQL or
MySQL or MongoDB or Redis database for user accounts.
Use /usr/local/share/turnserver/schema.sql as SQL database schema,
or use /usr/local/share/turnserver/schema.userdb.redis as Redis
database schema description and/or
/usr/local/share/turnserver/schema.stats.redis
as Redis status & statistics database schema description.
If you are using SQLite, the default database location is in
/var/db/turndb or in /usr/local/var/db/turndb or in /var/lib/turn/turndb.
c) add whatever is necessary to enable start-up daemon for the
/usr/local/bin/turnserver.
2) If you do not want the turnserver to be a system service,
then you can start/stop it "manually", using the "turnserver"
executable with appropriate options (see the documentation).
3) To create database schema, use schema in file
/usr/local/share/turnserver/schema.sql.
4) For additional information, run:
$ man turnserver
$ man turnadmin
$ man turnutils
==================================================================4、配置
在bin目录下生成六个可执行文件
turnadmin turnutils_peer.exe turnutils_stunclient.exe turnserver.exe turnutils_rfc5769check.exe turnutils_uclient.exe
turnserver.exe 就是我们需要的服务器.
turnadmin 用来管理账户.
turnutils_stunclient.exe 用于测试stun服务
turnutils_uclient.exe 用于测试turn服务. 模拟多个UDP,TCP,TLS or DTLS 类型的客户端
example 目录主要是示范如何配置和使用turn. 包含一些测试用例.
example/etc 下是pem证书和conf配置文件
example/var/db 下是sqlite的db库. 用于示范数据库的格式.
coturn 支持三种配置. 命令行, conf文件和数据库.
数据库支持sqlite, mysql, postgresql, MongoDB, redis.目前测试的Cygwin环境下编译的coTurn不支持MongoDB和redis,因为暂时用不到，所以也就没有查找如何才能编译支持到上述数据库
更具体的说明可以看源码目录下的README.turnserver README.turnadmin README.turnutils
examples\scripts 下一些测试用例:
loadbalance 示范如何进行负载均衡. 设置一个master turn server 然后配置若干个slave turn server.
longtermsecure 示范如何使用long-term 验证
longtermsecuredb 与 longtermsecure 类似, 不过是从数据库配置
shorttermsecure 示范如何使用short-term验证.
restapi 示范了web方面的使用.
stun 定义了两种验证方式.
Long-Term CredentialShort-Term Credential
具体可以参考stun标准 http://tools.ietf.org/html/rfc5389#section-15.4
若用于WebRTC，必须使用long-term
简单配置：
turnserver -o -a -f -v --mobility -m 10 --max-bps=100000 --min-port=32355 --max-port=65535 --user=webrtc0:webrtc1234 --user=webrtc1:webrtc1234 -r demo
-m 10 表示启动十个relay线程.
当TURN Server用于WebRTC时，必须使用long-term credential mechanism, 即指定 -a 或者 --lt-cred-mech
--max-bps=100000 限制最大速度为100KB/s.
添加了两个用户webrtc0 和webrtc1.
可以直接使用turnutils_uclient -u ling -w webrtc1234 来测试. turnutils_uclient 有很多参数可以配置的.
| 1 2 3 4 5 |
|
下面的配置文件和上面的配置命令是两种方式，在实际应用中只能用一种。
在这里要注意，在bin路径下，建配置文件turnserver.conf，内容为：
listening-ip=192.168.1.113//这是个公网ip
listening-port=3478
#relay-ip=0.0.0.0
external-ip=0.0.0.0
min-port=59000
max-port=65000
Verbose
fingerprint
no-stdout-log
syslog
cert=pem/turn_server_cert.pem
pkey=pem/turn_server_pkey.pem
user=demo:demo
no-tcp
no-tls
no-tcp-relay
stun-only
#secure-stun
如果用的是阿里云服务器，要开放3478端口，tcp、udp都打开。
这里turnserver就开启成功了，测试可以用https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ 来测试服务器是否成功。
