安装完成后会自动设置为开机启动和系统服务，系统服务命令如下：

systemctl start coturn
systemctl stop coturn
systemctl status coturn
systemctl status coturn
# 这是“systemctl status coturn”输出的状态，我们可以看到已经启动了，用的配置文件是：/etc/turnserver.conf

对了，创建一下证书文件

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


# key
/etc/turn_server_pkey.pem 
# cert
/etc/turn_server_cert.pem

这时候，我们需要编辑一下配置文件，把下面的信息修改为你的信息，放到文件尾即可。

# 监听器接口设备(可选，仅适用于Linux)。
listening-device=eth0
# 指定侦听的端口。
listening-port=3478
tls-listening-port=5349
# 用于中继接口设备(可选，仅适用于Linux)。
relay-device=eth0

#中继地址(将用于中继的本地IP地址向对等方发送的数据包数量)。
#可以使用多个中继地址。
#相同的IP可用作监听IP和中继IP。
#如果没有指定中继IP，则turnserver将应用默认值
#策略:它将自己决定使用哪些中继地址，并且它将始终使用客户端套接字IP地址作为中继IP地址TURN会话的#如果请求的中继地址族相同作为客户端套接字的系列)。
relay-ip=172.22.112.86

#  云主机内网 IP 地址。
listening-ip=xxx.xxx.xxx.xxx

#  云主机的公网 IP 地址。
external-ip=xxx.xxx.xxx.xxx
# 这个很重要，如果没有配置这个就服务使用中转服务。

云主机端口配置

        如果是阿里云、腾讯云的云主机，需要到控制中的安全策略组或者防火墙中允许 3478、49152-65535 端口 UDP/TCP通行。

• 测试 STUN/TURN 服务，使用火狐浏览器（其他浏览器有问题）打开以下连接
• Trickle ICE 出现 relay 说明配置成功。
  
• 
  
  完成。。。
