备注：
此服务端 nodejs 代码和安卓客户端代码是在 ddssingsong 大神 github 上 fork 过来,在此贴上
他的github地址, https://github.com/ddssingsong/ ,再次感谢。

一、安装环境依赖

1.1). 下载nodejs：

https://nodejs.org/en/download/
测试使用的版本:v16.13.2

//> 解压
tar -xvf node-v16.13.2-linux-x64.tar.xz
//> 改名
mv node-v16.13.2-linux-x64 nodejs
//> 进入目录
cd nodejs/
//> 确认一下nodejs下bin目录是否有node和npm文件，如果有就可以执行软连接
sudo ln -s /root/webRTC/nodejs/bin/npm /usr/local/bin/
sudo ln -s /root/webRTC/nodejs/bin/node /usr/local/bin/
//> 版本信息
[root@iZ8vbdsaostzzry9mmk5lrZ webRTC]# ls /usr/local/bin/npm -la
lrwxrwxrwx 1 root root 27 Jan 13 10:11 /usr/local/bin/npm -> /root/webRTC/nodejs/bin/npm
[root@iZ8vbdsaostzzry9mmk5lrZ webRTC]# npm -v
8.3.0
[root@iZ8vbdsaostzzry9mmk5lrZ webRTC]# ls /usr/local/bin/node -la
lrwxrwxrwx 1 root root 28 Jan 13 10:11 /usr/local/bin/node -> /root/webRTC/nodejs/bin/node
[root@iZ8vbdsaostzzry9mmk5lrZ webRTC]# node -v
v16.13.2

1.2) 安装相关依赖包

    $ sudo yum install openssl-devel
    $ sudo yum install sqlite3
    $ sudo yum install sqlite-devel
    $ sudo yum install libevent
    $ sudo yum install libevent-devel
    $ sudo yum install coturn

二、 房间与信令服务

本次实验只测试 安卓客户端与客户端直连功能，不测试pc端web服务，所以不用修改服务端代码，
直接运行server.js 服务即可。

2.1 下载服务端源码、安装 SkyRTC 依赖包

$ git clone https://github.com/dtltljb/webrtc_server_node.git
$ cd webrtc_server_node
$ npm install  //> 安装依赖模块

2.1 运行服务及日志

[root@iZ8vbdsaostzzry9mmk5lrZ webrtc_server_node]# node server.js

三、 ICE（STUN、TURN）服务

3.1 安装

安装 coturn 服务有两种方法，直接安装和下载源码安装。

//> centos 7 直接安装
$ sudo yum install coturn

下载源码安装:

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

此两种安装方式缺省配置文件路径有些差异，需注意一下。
验证验证。

router@ubuntu:~/webRTC/webrtc_server_node$ which turnserver
/usr/local/bin/turnserver

3.2 创建数据库

coturn的“瞬时认证”需要依赖数据库，如果我们的用户量较大可以考虑采用其他数据库；
采用源码安装coturn时，源码文件夹下/turndb/schema.sql 是 sqlite3 数据库初始化内容.

//> 配置数据库
router@ubuntu:~/webRTC$ rm -f /usr/local/var/db/turndb
router@ubuntu:~/webRTC$ cat coturn/turndb/schema.sql |sqlite3 /usr/local/var/db/turndb
//> 查看数据表
router@ubuntu:~/webRTC$ sqlite3 /usr/local/var/db/turndb
SQLite version 3.31.1 2020-01-27 19:55:54
Enter ".help" for usage hints.
sqlite> .tables
admin_user            oauth_key             turn_secret         
allowed_peer_ip       turn_origin_to_realm  turnusers_lt        
denied_peer_ip        turn_realm_option

//> 数据库表list
router@ubuntu:~/webRTC$ cat coturn/turndb/schema.sql 
CREATE TABLE turnusers_lt (
    realm varchar(127) default '',
    name varchar(512),
    hmackey char(128),
    PRIMARY KEY (realm,name)
);

CREATE TABLE turn_secret (
  realm varchar(127) default '',
  value varchar(256),
  primary key (realm,value)
);

CREATE TABLE allowed_peer_ip (
  realm varchar(127) default '',
  ip_range varchar(256),
  primary key (realm,ip_range)
);

CREATE TABLE denied_peer_ip (
  realm varchar(127) default '',
  ip_range varchar(256),
  primary key (realm,ip_range)
);

CREATE TABLE turn_origin_to_realm (
  origin varchar(127),
  realm varchar(127),
  primary key (origin)
);

CREATE TABLE turn_realm_option (
  realm varchar(127) default '',
  opt varchar(32),
  value varchar(128),
  primary key (realm,opt)
);

CREATE TABLE oauth_key (
  kid varchar(128),
  ikm_key varchar(256),
  timestamp bigint default 0,
  lifetime integer default 0,
  as_rs_alg varchar(64) default '',
  realm varchar(127),
  primary key (kid)
);

CREATE TABLE admin_user (
  name varchar(32),
  realm varchar(127),
  password varchar(127),
  primary key (name)
);

本次实验测试实验采用静态用户名方式，不安装数据库应该也可以使用的，我没有测试过。

3.3 turnserver.conf配置文件

本次实验配置文件内容和路径。

[root@iZ8vbdsaostzzry9mmk5lrZ webRTC]# cat /etc/coturn/turnserver.conf
# RFC5766-TURN-SERVER configuration file
# RFC5766-TURN-SERVER配置文件

# TURN为UDP和TCP的侦听器端口(默认: 3478)。
# 注:实际上,TLS和DTLS会话可以连接到"清晰的"TCP和UDP端口,——如果允许配置。
#
#listening-port=3478
listening-port=3478

# TURN为TLS的侦听器端口(默认: 5349)。
# 注意:事实上,"清晰的"TCP和UDP会话可以连接到TLS和DTLS端口，如果允许配置。
# TURN服务器"自动"识别传输类型。实际上,两个监听终端点("清晰的"端和"TLS"端)是
# 对等的功能;但我们保持两个端点来满足RFC 5766规范。
# 对于安全的TCP连接,我们目前支持SSL的3个版本，是TLS 1.0版本,1.1版本和1.2版本。
# SSL2还支持"encapculation模式"。对于安全的UDP连接,我们支持DTLS版本1。
#
tls-listening-port=5349

# 侦听器中继服务器的IP地址。可以指定多个侦听器。
# 如果没有在配置文件或者命令选项中指定监听的IP，
# 那么所有的IPv4和IPv6所有的IP将被监听
#
listening-ip=172.26.43.146
#listening-ip=2607:f0d0:1002:51::4

# 中继地址(本地IP地址将用于传递数据包的给每个端)
# 可以使用多个中继地址。
# 相同的IP可以用作监听IP和继电器IP。
# 如果没有指定中继IP，那么turnserver将应用默认策略：它将自行决定使用那个中继
# 地址，并且它总是会使用客户端套接字的IP地址作为中继的IP地址在TURN会话中(如果
# 请求的中继地址族解决同族的客户端套接字)。
#
relay-ip=172.26.43.146
#relay-ip=2607:f0d0:1002:51::5


# By default, this value is empty, and no address mapping is used.
#
external-ip=39.99.xx.xx
#OR:
#external-ip=60.70.80.91/172.17.19.101

# Number of relay threads to handle the established connections
# (in addition to authentication thread and the listener thread).
# If set to 0 then application runs relay process in a single thread,
# in the same thread with the listener process (the authentication thread will
# still be a separate thread).
# In the older systems (Linux kernel before 3.9),
# the number of UDP threads is always one thread per network listening endpoint -
# including the auxiliary endpoints - unless 0 (zero) or 1 (one) value is set.
relay-threads=5

# UDP中继端点的上下边界:
# (默认是49152至65535)
#
min-port=59000
max-port=65500
    
# 取消TURN服务器运行'normal' 'moderate'详细模式。
# 默认情况下,详细模式是关闭的。
#
verbose
    
# 取消在TURN消息中使用指纹。
# 默认情况下,指纹是关闭的。
#
fingerprint


# 取消使用长期证书机制。
# 默认情况下不使用凭证机制(允许任何用户)。
# 这个选项可能使用用户数据文件或PostgreSQL或MySQL或Redis来存储用户密钥。
#
lt-cred-mech

# 'Static'用户长期占凭证机制。
# 这个选项不能用于TURN REST API或短期凭证机制。
# 'Static'用户帐户不是turnserver程序动态检查,所以他们不能改变在turnserver运行时。
# Or, equivalently, with open clear password (less secure):
#或者是这样，明文密码(不安全的):
#
user=ddssingsong:123456

# 'Dynamic'用户帐户数据库文件名。
# 只有用户长期机制可以存储在一个文件,短期机制不会处理选项,短期机制需要PostgreSQL或MySQL或
# Redis数据库。
# 'Dynamic'的长期用户帐户在turnserver程序中动态检查的,这样他们可以改变的在turnserver运行时。
# 默认文件名是turnuserdb.conf.
 userdb=/etc/coturn/turndb  

# TURN REST API的长期凭证机制范围。
#
realm=metis.org

# 如果没有TLS客户端监听器需要取消。
# 默认情况下TLS客户端监听器总是启动。
#
no-tls

# 如果不允许TCP中继端点需要取消。
# 默认情况下启用TCP继电器端点(如在RFC 5766)。
#
no-tcp-relay

# 取消如果需要额外的安全,现时已有有限的生命周期(600秒)。
# 默认情况下,一个会话的唯一临界值,但它一般拥有无限的生命周期。这个选项,临界值
# 仅限于600秒,之后,客户端将得到438错误,将不得不重新认证。
#
stale-nonce

# 证书文件。
# 使用绝对路径或路径相对于配置文件。
#
cert=/etc/turn_server_cert.pem
# 私钥文件。
# 使用绝对路径或路径相对于配置文件。使用PEM文件格式。
#
pkey=/etc/turn_server_pkey.pem

# 设置日志文件
# 默认情况下,turnserver尝试一个日志文件在/var/log,/var/tmp,/tmp和
# 当前目录(那个文件先打开成功,文件将被使用)。
# 采用这一选项可以设置明确的日志文件名。
# 特殊的名字是"stdout"和"-"——他们将强制所有的输出。同时,"syslog"名称将强制所有的系统日志(syslog)。
# 在运行时,日志文件可以重置通过SIGHUP信号在turnserver程序中。
#
log-file=/var/tmp/turn.log

# 标记用于不接受的端在环回地址(127.x.x.x 和 ::1)。
# 这是一个额外的安全措施。
no-loopback-peers

# 标记用于不接受的端在广播地址(224.0.0.0和以上的，和FFXX:*)。
# 这是一个额外的安全措施。
no-multicast-peers

# 存储进程pid的文件名。
# 默认是/var/run/turnserver.pid(超级用户使用)或者是/var/tmp/turnserver.pid
#
#pidfile="/var/run/turnserver.pid"
pidfile="/var/tmp/turnserver.pid"

# Mobility with ICE (MICE) specs support.
#
# 移动的ICE(MICE)的规范支持。
#
mobility

#
# 关掉CLI的支持。
# 默认情况下它总是ON。
# 参阅选项cli-ip和cli-port。
no-cli

四、 安卓客户端

4.1 下载源码切换分支

git clone https://github.com/dtltljb/webrtc_android.git
cd webrtc_android
git branch -a
git checkout branch_nodejs

切换分支后，我的android studio是3.5 版本，打开直接编译通过,感谢 ddssingsong 大神的分享。

4.2 修改源码

//> 第一处修改: 登录界面 ip 地址和http协议,app/src/main/java/com/dds/nodejs/NodejsActivity.java
public class NodejsActivity extends AppCompatActivity {
    private EditText et_signal;
    private EditText et_room;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_nodejs);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        initView();
        initVar();

    }
    //> 修改部分
    private void initVar() {
        et_signal.setText("http://39.99.xx.xx:3000/wss");
        et_room.setText("232343");
    }

}

//> 第二处修改: /app/src/main/java/com/dds/nodejs/WebrtcUtil.java
public class WebrtcUtil {

    //public static final String HOST = "47.93.186.97";
    public static final String HOST = "39.99.xx.xx";

    // turn and stun
    private static MyIceServer[] iceServers = {
            new MyIceServer("stun:stun.l.google.com:19302"),
            // 测试地址1
            new MyIceServer("stun:" + HOST + ":3478?transport=udp"),
            new MyIceServer("turn:" + HOST + ":3478?transport=udp",
                    "ddssingsong",
                    "123456"),
            new MyIceServer("turn:" + HOST + ":3478?transport=tcp",
                    "ddssingsong",
                    "123456"),
    };
    ......
}

本次实验未采用 nginx 代理 ws 服务，所以代码修改为http协议。本次实验以简单粗暴方式，搭建处系统运行基本环境为主旨。
本次在网上也看了很多相关内容，本次实验环境非常简洁方式。

五、网络环境处理

由于本次实验是在阿里云ecs上，需要进入阿里 ECS 控制台开启输入规则并关闭 Centos 7 系统的防火墙。

阿里云网络与安全

进入控制台后、选择 ECS 实例、左侧有"网络与安全"选项，在"入方向"栏中，手动增加"3478、5349、3000" TCP和UDP端口放行规则。

关闭 Centos 防火墙

systemctl stop firewalld.service.
systemctl disable firewalld.service.
此命令是临时性的关闭。

六、实验验证结果记录及图片

至此webRTC系统运行环境就搭建完成，直接启动 turnserver 服务就可以，输出日志内容如下。
