webrtc（coturn服务器搭建）

coturn服务器安装

1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

2下载编译安装coturn

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

输入which turnserver，若是打印出路径，说明安装成功

3 配置coturn

使用turnadmin生成安全访问密码
turnadmin -k -u username -r north.gov -p password

/usr/local/etc/turnserver.conf配置
#listening-ip与relay-ip采用内网ip，external-ip是外网的ip

listening-port=444 #监听端口
external-ip=210.21.53.158 #外网IP
verbose
fingerprint
lt-cred-mech
realm=test
user=username:生成的加密密码    #修改为本身的
user=username:password       #修改为本身的
stale-nonce
no-loopback-peers
no-multicast-peers
mobility
no-cli

4启动coturn

turnserver -o -a

5ICE测试

relay地址回来的是你的ip才算穿透成功。
