turnserver服务器搭建

亲测有效，有问题，欢迎留言。

搭建环境：Ubuntu 16.04.6 LTS

下载并安装libevent-2.0

wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz tar zxvf libevent-2.0.21-stable.tar.gz cd libevent-2.0.21-stable && ./configure make && make install

下载编译安装coturn

git clone https://github.com/coturn/coturn cd coturn ./configure make make install

查看是否安装成功

which turnserver

创建用户名和密码：

turnadmin -k -u demo -r hangzhou -p demo

生成：0xc74d8dd2c3dac2f1d40b57b9c33e644d （后面的配置文件需要用到用户名和密码）

配置文件

在/usr/local/etc/目录下有turnserver.conf.default，复制为turnserver.conf

cd /usr/local/etc/ cp turnserver.conf.default turnserver.conf

首先查看网卡,记录网卡名称和内网地址

签名证书

apt-get install openssl

cert和pkey配置的自签名证书用Openssl命令生成:

sudo openssl req -x509 -newkey rsa:2048 -keyout /etc/turn_server_pkey.pem -out /etc/turn_server_cert.pem -days 99999 -nodes

填写相关信息随便写。

生成的两个文件一般在/etc/目录下

修改配置信息

vi /usr/local/etc/turnserver.conf

listening-ip与relay-ip采用内网ip，external-ip是外网的ip

正常使用的配置文件：

//***********************************************************************//

listening-device=enp4s3 #与前ifconfig查到的网卡名称一致

relay-device=enp4s3 #与前ifconfig查到的网卡名称一致

listening-ip=192.168.10.206 #内网IP

listening-port=3478

tls-listening-port=5349

relay-ip=192.168.10.206 #内网IP

external-ip=115.238.103.171 #公网IP

relay-threads=50

//**************************************************************************************//

字段说明：

listening-port: turnserver监听UDP/TCP端口,默认为3478;

tls-listening-port: turnserver监听TLS/DTLS端口,默认为5349,

将TCP/UDP和TLS/DTLS分别定义监听端口是符合RFC5766规范的,但是通过配置两者能使用同一端口,不推荐;

listening-ip: 中继服务器的监听IP地址,可以配置多个;

relay-ip: 中继服务器的IP地址;

external-ip: 外部IP,当中继服务器在NAT网络内部时指定,此处可以不添加;

server-name: 服务器名称,用于OAuth认证,默认和realm相同;

realm: 域名;

userdb: 用于保存用户信息;

cert/pkey: 自签名证书相关;

开启turnserver，执行命令

cd /coturn/bin

turnserver -v -r 外网IP:3478 -a -o

turnserver -v -r 115.238.103.171:3478 -a -o

运行结果：

ICE测试

只有relay地址回来的是你的ip才算穿透成功。
