libevent下载安装
依赖libevent开源库，需要先进行安装：
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 installcoturn下载安装
git clone https://github.com/coturn/coturn
cd coturn
./configure
make
make install查看是否安装成功
which turnserver修改配置信息
vi /usr/local/etc/turnserver.conf修改配置文件信息：
relay-device=eth0 #与前ifconfig查到的网卡名称一致
listening-ip=106.75.26.76 #内网IP
listening-port=3478 #默认端口号
tls-listening-port=5349
relay-ip=10.10.128.111
external-ip=10.10.128.111 #公网IP
relay-threads=50
lt-cred-mech
cert=/etc/turn_server_cert.pem
pkey=/etc/turn_server_pkey.pem
pidfile=”/var/run/turnserver.pid”
min-port=49152 #最小端口号
max-port=65535 #最大端口号
user=ceshi:123456 #用户名密码，创建IceServer时用用户名密码使用如下：
List<String> urls = new ArrayList<>();
urls.add("turn:106.75.26.76:3478?transport=udp");
urls.add("turn:106.75.26.76:3478?transport=tcp");
this.iceServers.add(PeerConnection.IceServer.builder(urls).setUsername("ceshi").setPassword("123456").setTlsCertPolicy(TLS_CERT_POLICY_SECURE).createIceServer());
启动服务
turnserver -o -a -f -user=ceshi:123456 -r Beijing遇见的问题
问题1：
[root@10-10-128-155 coturn]# ./configure
install is /usr/bin/install
pkill is /usr/bin/pkill
sqlite3 is /usr/bin/sqlite3
Use TMP dir /var/tmp
Compiler: cc
Library option -lsocket cannot be used
Library option -lwldap32 cannot be used
Library option -lwldap64 cannot be used
Library option -lintl cannot be used
Sockets code is fine: no sin_len field present
Ignore IP_RECVERR
Library option -lcrypto cannot be used
ERROR: OpenSSL Crypto development libraries are not installed properly in required location.
Abort.解决方案：
需要依赖openssl库
yum install openssl-devel问题2：
CONFIG ERROR: Empty cli-password, and so telnet cli interface is disabled! Please set a non empty cli-password!解决方案：
在配置文件/usr/local/etc/turnserver.conf中，添加cli-password字段，修改后的配置文件如下：
relay-device=eth0 #与前ifconfig查到的网卡名称一致
listening-ip=106.75.26.76 #内网IP
listening-port=3478 #默认端口号
tls-listening-port=5349
relay-ip=10.10.128.111
external-ip=10.10.128.111 #公网IP
relay-threads=50
lt-cred-mech
cert=/etc/turn_server_cert.pem
pkey=/etc/turn_server_pkey.pem
pidfile=”/var/run/turnserver.pid”
min-port=49152 #最小端口号
max-port=65535 #最大端口号
user=ceshi:123456 #用户名密码，创建IceServer时用
cli-password=123456补充
如果以上步骤后发现穿透服务器无法工作，可以在执行时尝试添加- v参数，打印更详细的日志，https://blog.csdn.net/Martin_chen2/article/details/102970731也记录了我部署coturn的问题，可供参考。
