1.1.1  Turnserver

1.1.1.1 官网：http://turnserver.sourceforge.net/

（最新地址http://sourceforge.net/projects/turnserver/）

1.1.1.2 支持协议：

TURN and STUN Request For Comments (respectively RFC 5766 and RFC5389)。RFC6156 namely TURN-IPV6 (relay between IPv4-IPv6, IPv6-IPv4 andIPv6-IPv6 addresses) and RFC6062 namely TURN-TCP (relay data with TCP)。

1.1.1.3 下载源码：

[root@rlnf-76home]# svn co svn://svn.code.sf.net/p/turnserver/code/trunk turnserver

（我是从http://sourceforge.net/projects/turnserver/下载的源代码上传服务器

然后

tar jxvf XX.tar.bz2

如果tar不支持j选项，就用下面方式解压

bzip2 -d  XX.tar.bz2

tar -xvf  XX.tar.bz2

）

1.1.1.4 安装依赖

1.1.1.4.1 libConfuse

1.       官网: http://www.nongnu.org/confuse/

2.       下载并安装libconfuse依赖:

[root@rlnf-76 home]# git clone https://github.com/martinh/libconfuse.git

[root@rlnf-76home]# cd turnserver/

[root@rlnf-76libconfuse]# ./autogen.sh

[root@rlnf-76libconfuse]# ./configure --prefix=/usr

[root@rlnf-76libconfuse]# make install

3.       安装依赖：

l  Ubuntu:

sudoapt-get install flex

l  CentOS:

yuminstall flex

1.1.1.5 产生配置脚本：

[root@rlnf-76turnserver]# cd turnserver

[root@rlnf-76turnserver]# autoreconf --install

1.1.1.6 编译

[root@rlnf-76turnserver]# ./configure --enable-debug-build

--enable-debug-build：允许编译调试信息，用于调试。发行版本不需要这个参数。

[root@rlnf-76turnserver]# make

[root@rlnf-76turnserver]# make install

1.1.1.7  编译时可能会出现的问题

l  在CentOS下可能会出现下面错误：

编译json-c arm版本 可以顺利通过， 但是链接json-c动态库的时候会有提示: undefined reference to rpl_malloc

按照网上的搜索结果在configure的时候加上--with-gnu-ld和config.h里加上#undefine rpl_malloc都不能解决问题。

后来发现config.h.in里定义了

#undef malloc

#undef realloc

把这两个去掉，编译顺利通过。

l  Ubuntu下可能会出现的下面错误：

util_sys.c:259:14: error: ignoring returnvalue of ‘setegid’, declared with attribute warn_unused_result[-Werror=unused-result]

setegid(gid_real);

^

util_sys.c:270:14: error: ignoring returnvalue of ‘setegid’, declared with attribute warn_unused_result[-Werror=unused-result]

setegid(user.pw_gid);

^

util_sys.c: In function‘sys_gain_privileges’:

util_sys.c:291:10: error: ignoring returnvalue of ‘setegid’, declared with attribute warn_unused_result[-Werror=unused-result]

setegid(gid_eff);

^

cc1: all warnings being treated as errors

解决方法：

把src/Makefile.am文件中的下面警告标志去掉：

-Wall -Wextra -Werror

1.1.1.8   配置

在源码根目录下的extra目录下有配置模板可以参考。

[root@rlnf-76extra]# ls

turnserver.fedora.initd #fedora平台的启动脚本

turnserver.spec         #fedora平台的启动脚本

turnserver.debian.initd #debian平台的启动脚本

turnserver.conf.template#配置文件

turnusers.txt.template  #用户名、密码配置文件

1.1.1.9  建立配置文件：

[root@rlnf-76turnserver]# cd extra/

[root@rlnf-76extra]# cp turnserver.conf.template /usr/local/etc/turnserver.conf

[root@rlnf-76extra]# cp turnusers.txt.template /usr/local/etc/turnusers.txt

[root@rlnf-76extra]# cd /usr/local/etc

1.1.1.10      修改配置文件：

[root@rlnf-76etc]# vi turnserver.conf

listen_address = {"183.62.225.76" }           #把公网IP地址写入，一般只要改这个配置，其它的用默认值就可以了。

## Account method.

account_method = "file"                        #配置账户数据为文件

## Account file (if account_method = file).

account_file ="/usr/local/etc/turnusers.txt" #指定账户文件位置

[root@rlnf-76etc]# vi turnusers.txt

foo:bar:domain.org:authorized

用户名：密码：领域：需要验证的

1.1.1.11      启动turnserver：

[root@rlnf-76etc]# cd ../sbin

[root@rlnf-76sbin]# ./turnserver -c /usr/local/etc/turnserver.conf

1.1.1.12      启动回显服务：

[root@rlnf-76bin]# ./test_echo_server

UDP Echo server started on port 4588

1.1.1.13      测试服务器是否正常

在其它机器上启动测试程序：

rdc@rdc-Virtual-Machine:/home/turnserver/src$./test_turn_client -t udp -s 183.62.225.76 -p 183.62.225.76 -w 4588 -u foo -g 1234-d domain.org   

Protocol: udp (17) use TLS: 0.

sock: 3 speer: (nil) connected!

Send Allocate request.

Send Allocate request.

Probably wrong credentials or requestedfamily not supported.

这个是说权限错误，一般是用户或密码不对。修改用户和密码，再次运行：

rdc@rdc-Virtual-Machine:/home/turnserver/src$./test_turn_client -t udp -s 183.62.225.76 -p 183.62.225.76 -w 4588 -u foo -gbar -d domain.org
