搭建turn服务器
编译环境搭建
Vagrant
Windows用户要想在Windows下编译rfc5766-turn-server的话，需安装虚拟机，我推荐程序员专用的虚拟机——Vagrant，Linux用户请忽略。其配置文件如下：
Vagrantfile
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | # -*- mode: ruby -*- # vi: set ft=ruby : VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "hashicorp/precise64" config.vm.box_url = "virtualbox.box" config.vm.provider "virtualbox" do |vb| vb.memory = 2048 vb.cpus = 2 end end |
使用命令行启动它：
| 1 2 | vagrant up vagrant ssh |
安装编译工具链
| 1 | sudo apt-get install build-essential |
确认安装成功：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | vagrant@precise64:~$ gcc -v Using built-in specs.

安装依赖项
| 1 2 3 4 5 6 | sudo apt-get install libssl-dev sudo apt-get install libevent-dev sudo apt-get install libpq-dev sudo apt-get install mysql-client sudo apt-get install libmysqlclient-dev sudo apt-get install libhiredis-dev |
其中SQL相关的依赖项可能会失败，不过这也没什么大不了的，SQL库是为了支持更多用户而准备的，如果你不是生产环境的话，忽略也行。
检出代码
在Vagrantfile的同一目录检出https://code.google.com/p/rfc5766-turn-server/source/checkout 到任意目录，我检出到了stun，下文脚本请注意自行对号入座。
cd进去
| 1 2 3 4 5 6 7 8 9 10 11 | vagrant@precise64:~$ cd /vagrant vagrant@precise64:/vagrant$ ls down.cmd stun up.cmd Vagrantfile vagrant@precise64:/vagrant$ cd stun vagrant@precise64:/vagrant/stun$ ls AUTHORS examples LICENSE.OpenSSL NOTE rpm bin include Makefile postinstall.txt src build INSTALL Makefile.in README.turnadmin STATUS ChangeLog lib make-man.sh README.turnserver TODO configure LICENSE man README.turnutils turndb vagrant@precise64:/vagrant/stun$ |
开始编译
生成makefile文件，编译，安装
| 1 2 3 | ./configure make sudo make install |
测试
试试看是否编译成功，先看看turnserver支持哪些功能
| 1 | turnserver -h > help.txt |
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | 0: log file opened: /var/tmp/turn_1313_2014-11-04.log 0: RFC 3489/5389/5766/5780/6062/6156 STUN/TURN Server Version Citrix-3.2.4.6 'Marshal West' 0: Max number of open files/sockets allowed for this process: 4096 0: Due to the open files/sockets limitation, max supported number of TURN Sessions possible is: 2000 (approximately) 0: ==== Show him the instruments, Practical Frost: ==== 0: TLS supported 0: DTLS supported 0: Redis supported 0: PostgreSQL is not supported 0: MySQL is not supported 0: OpenSSL compile-time version 0x1000100f: fresh enough 0: Default Net Engine version: 2 (UDP thread per network endpoint) ===================================================== Usage: turnserver [options] Options: -d, --listening-device <device-name> Listener interface device (NOT RECOMMENDED.

支持协议
测试各基础协议是否支持
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | $ cd examples vagrant@precise64:/vagrant/stun/examples$ ./scripts/rfc5769.sh RFC 5769 message fingerprint test(0) result: success RFC 5769 simple request short-term credentials and integrity test result: succes s RFC 5769 NEGATIVE fingerprint test(0) result: success RFC 5769 message structure, long-term credentials and integrity test result: suc cess RFC 5769 message encoding test result: success RFC 5769 NEGATIVE long-term credentials test result: success RFC 5769 message fingerprint test(1) result: success RFC 5769 IPv4 response short-term credentials and integrity test result: success RFC 5769 NEGATIVE fingerprint test(1) result: success RFC 5769 IPv4 encoding result: success RFC 5769 message fingerprint test(2) result: success RFC 5769 IPv6 response short-term credentials and integrity test result: success RFC 5769 NEGATIVE fingerprint test(2) result: success RFC 5769 IPv6 encoding result: success vagrant@precise64:/vagrant/stun/examples$ |
TURN测试
先安装screen
| 1 | sudo apt-get install screen |
这样我们就能在一个终端里运行多个窗口了，使用快捷键Ctrl+a+c新建一个窗口，通过执行命令
| 1 | ./scripts/basic/relay.sh |
把TURN服务器运行起来：
然后执行命令：
| 1 | ./scripts/basic/udp_c2c_client.sh |
把客户端跑起来，可以看到它在通过中转服务器自己给自己发数据：
通过Ctrl+a+n来切回服务器的窗口，观察到它的确在收发数据：
至此，说明一切完全正常。
