webrtc服务器环境搭建

(基于公网环境)

Last Modified Date: 2017/8/2

1. 搭建平台

操作系统： Ubuntu 16.04 server(64bits)
Google webrtc的服务器Demo：详见https://github.com/webrtc/apprtc
域名： webrtc.olcms.com
IP地址： 需要是公网地址

2. 软件安装

安装JDK：

add-apt-repository ppa:openjdk-r/ppa apt-get update apt-get install openjdk-8-jdk

安装nodejs相关包：

apt-get install nodejsapt-get install npm  apt-get install nodejs-legacy npm -g install grunt-cli

安装Python和Python-webtest：

apt-get install python apt-get install python-webtest

注：若已安装过上述软件，可忽略；如上述未提及的软件需要安装，请自行安装。

3. 搭建房间服务器(Room Server)

下载apprtc源码（操作所在目录/root/）

git clone  https://github.com/webrtc/apprtc.git   cd apprtcnpm install

若npm install报错，请自行解决。

修改文件
1.修改/root/apprtc/src/app_engine/constants.py

TURN_BASE_URL = 'https://webrtc.olcms.com'; #本机域名webrtc.olcms.com TURN_URL_TEMPLATE = '%s/turn.php?username=%s&key=%s'; #如果turn.php未实现，可使用默认配置CEOD_KEY = 'inesadt'   #此处后面turn配置的用户名保持一致ICE_SERVER_BASE_URL = 'https://webrtc.olcms.com';ICE_SERVER_URL_TEMPLATE = '%s/iceconfig.php?key=%s'; #如果iceconfig.php未实现，可用默认配置，但是Android Apk会有问题WSS_INSTANCE_HOST_KEY = 'webrtc.olcms.com:8089'  #信令服务器端口号8089  WSS_INSTANCE_NAME_KEY = 'vm_name'WSS_INSTANCE_ZONE_KEY = 'zone'WSS_INSTANCES = [{        WSS_INSTANCE_HOST_KEY: 'webrtc.olcms.com:8089',        WSS_INSTANCE_NAME_KEY: 'wsserver-std',        WSS_INSTANCE_ZONE_KEY: 'us-central1-a'          }, {          WSS_INSTANCE_HOST_KEY: 'webrtc.olcms.com:8089',        WSS_INSTANCE_NAME_KEY: 'wsserver-std-2',         WSS_INSTANCE_ZONE_KEY: 'us-central1-f'        }]

grunt build

编译完成之后，会生成out目录，房间服务器编译完成。

注（编译成功可忽略）：此处编译需要翻墙，若编译时无法翻墙，可下载手动下载https://api.callstats.io/static/callstats.min.js，并把文件callstats.min.js放到目录/root/apprtc/out/app_engine/third_party/callstats/下。然后修改/root/apprtc/build/build_app_engine_package.py文件：

    # Download callstats.    ......    ......    response = requests.get(urls[fileName])    #if response.status_code == 200:    #把此处注释掉    print 'Downloading %s to %s...' % (urls[fileName], path)    with open(path + fileName, 'w') as to_file:       to_file.write(response.text)    #else:  #把此处注释掉    #  raise NameError('Could not download: ' + filename + ' Error:' + \ #把此处注释掉    #str(response.status_code))  #把此处注释掉

然后继续进行编译即可。

安装和配置google app engine
1.下载google app engine
需翻墙，下载地址https://storage.googleapis.com/appengine-sdks/featured/google_appengine_1.9.50.zip)，或者通过其他地方下载。
2.配置google app engine 路径
解压google_appengine_1.9.50.zip

unzip google_appengine_1.9.50.zip

编辑/etc/profile文件，在文件最后添加语句：

export PATH="$PATH:/root/google_appengine/"

（当前安装目录是/root/google_appengine,请根据自己的安装目录进行配置）
保存profile文件，进行以下操作生效

source /etc/profile

运行房间服务器（room server)
在目录/root/google_appengine目录下找到dev_appserver.py脚本,执行以下语句

./dev_appserver.py --host=webrtc.olcms.com /root/apprtc/out/app_engine

若想后台运行，则执行

nohup ./dev_appserver.py --host=webrtc.olcms.com /root/apprtc/out/app_engine &

在浏览器中访问房间服务器
https://webrtc.olcms.com

4. 搭建信令服务器(Collider Server)

安装go语言编译器

apt-get install golang-go

复制collider源代码
（此源码在房间服务器源码目录下/root/apprtc/src/collider/)
在/root目录下新建文件夹

mkdir -p goWorkspace/src

配置编译环境，此配置是暂时有效的

export GOPATH=/root/goWorkspace/

把/root/apprtc/src/collider/目录下的三个目录（collider、collidermain、collidertest）复制到/root/goWorkspace/src/目录下

cp -rf /root/apprtc/src/collider/* /root/goWorkspace/src

修改代码
1.编辑文件/root/goWorkspace/src/collidermain/main.go，修改房间服务器的地址

var roomSrv = flag.String("room-server", "https://webrtc.olcms.com", "The origin of the room server")

2.编辑文件/root/goWorkspace/src/collider/collider.go，修改下面这句：

e = server.ListenAndServeTLS("/cert/cert.pem", "/cert/key.pem")

修改为

e = server.ListenAndServeTLS("/etc/letsencrypt/live/webrtc.olcms.com/fullchain.pem", "/etc/letsencrypt/live/webrtc.olcms.com/privkey.pem")

其中fullchain.pem和privkey.pem为SSL证书，具体证书路径根据实际路径进行配置，SSL证书生成见后续Nginx配置。

编译信令服务器
进入目录/root/goWorkspace/src/,此处编译需要翻墙。

go get collidermaingo install collidermain

编译成功后，在/root/goWorkspace/下会生成bin和pkg目录。
若此处编译时无法翻墙，可手动下载需要的文件。在/root/goWorkspace/src/目录下，

mkdir -p golang.org/x cd golang.org/x/git clone https://github.com/golang/net

然后再进行编译即可。

运行信令服务器
进入/root/goWorkspace/bin/目录，运行信令服务器

./collidermain -port=8089 -tls=true

若想后台运行，则执行

nohup ./collidermain -port=8089 -tls=true &

5. 搭建STUN\TURN服务器

安装coturn

apt-get install coturn

进行相关配置
1. 编辑文件/etc/default/coturn,把TURNSERVER_ENABLED=1的注释去掉。
2. 编辑文件/etc/turnserver.conf,把以下内容加入到文件最后（或者在文件中找到相应的选项，进行配置）

    listening-device=eth0  #此处eth0是电脑网卡名称    listening-port=3478     #turn服务器的端口号    relay-device=eth0   #此处eth0是电脑网卡名称    min-port=49152    max-port=65535    Verbose    fingerprint    lt-cred-mech    use-auth-secret    static-auth-secret=inesadt  #此处要和房间服务器配置时constants.py文件中的CODE_KEY保持一致。    user=inesadt:0x7e3a2ed35d3cf7f19e2f8b015a186f54    user=inesadt:inesadt    stale-nonce    cert=/usr/local/etc/turn_server_cert.pem    pkey=/usr/local/etc/turn_server_pkey.pem    no-loopback-peers    no-multicast-peers    mobility    no-cli

上述文件中 0x7e3a2ed35d3cf7f19e2f8b015a186f54的生成方法：
turnadmin -k -u inesadt -r north.gov -p inesadt
-k 表示生成一个long-term credential key
-u 表示用户名
-p 表示密码
-r 表示Realm域，（这个值的设置可能会有影响）。

coturn的证书生成（即配置文件中cert和pkey)

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

启动coturn服务器

service coturn start

6. 配置Nginx服务器

安装Nginx

apt-get install nginx

配置Nginx
编辑配置文件/etc/nginx/sites-available/default

    server {            listen 80 default_server;            listen [::]:80 default_server;            # SSL configuration            #            # listen 443 ssl default_server;            # listen [::]:443 ssl default_server;            #            # Note: You should disable gzip for SSL traffic.            # See: https://bugs.debian.org/773332            #            # Read up on ssl_ciphers to ensure a secure configuration.            # See: https://bugs.debian.org/765782            #            # Self signed certs generated by the ssl-cert package            # Don't use them in a production server!            #            # include snippets/snakeoil.conf;            root /var/www/html;            # Add index.php to the list if you are using PHP            index index.html index.htm index.nginx-debian.html;            server_name webrtc.olcms.com; #添加域名，如不添加，生成SSL证书时可能会有问题            location / {                    # First attempt to serve request as file, then                    # as directory, then fall back to displaying a 404.                 try_files $uri $uri/ =404;            }            .....            ....        }

生成SSL证书
1.使用let’s encrypt颁发的免费SSL证书，安装软件

sudo apt-get update  apt-get install software-properties-common  add-apt-repository ppa:certbot/certbot  apt-get update apt-get install python-certbot-nginx

2.生成SSL证书

    certbot --nginx certonly

SSL证书生成的目录/etc/letsencrypt/live/webrtc.olcms.com/,下面会有四个证书（cert.pem,chain.pem,fullchain.pem,privkey.pem）

PS：详见https://certbot.eff.org/#ubuntuxenial-nginx

安装php和php-fpm

apt-get install php  apt-get install php7.0-fpm

编辑配置文件/etc/nginx/sites-available/default

upstream roomserver {                server 114.215.131.216:8080;        }        server {                listen 80 ;                server_name webrtc.olcms.com;                return  301 https://$server_name$request_uri;        }        server {                # listen 80 default_server;                # listen [::]:80 default_server;                # SSL configuration                #                # listen 443 ssl default_server;                # listen [::]:443 ssl default_server;                listen 443;                #                # Note: You should disable gzip for SSL traffic.                # See: https://bugs.debian.org/773332                #                # Read up on ssl_ciphers to ensure a secure configuration.                # See: https://bugs.debian.org/765782                #                # Self signed certs generated by the ssl-cert package                # Don't use them in a production server!                #                # include snippets/snakeoil.conf;                root /var/www/html;                # Add index.php to the list if you are using PHP                index index.html index.htm index.nginx-debian.html index.php; #此处添加index.php                server_name webrtc.olcms.com;                # location / {                        # First attempt to serve request as file, then                        # as directory, then fall back to displaying a 404.                        # try_files $uri $uri/ =404;                # }               # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000                #                location ~ \.php$ {                        include snippets/fastcgi-php.conf;                        # With php7.0-cgi alone:                        #fastcgi_pass 127.0.0.1:9000;                        # With php7.0-fpm:                        fastcgi_pass unix:/run/php/php7.0-fpm.sock;                }                location / {                       proxy_pass http://roomserver$request_uri;                       proxy_set_header Host $host;                }                # deny access to .htaccess files, if Apache's document root                # concurs with nginx's one                #                #location ~ /\.ht {                #       deny all;                #}                ssl on;                ssl_certificate /etc/letsencrypt/live/webrtc.olcms.com/fullchain.pem;                ssl_certificate_key /etc/letsencrypt/live/webrtc.olcms.com/privkey.pem;        }

编写turn.php文件和iceconfig.php文件，并把文件放到目录/var/www/html/目录下

turn.php文件内容

 <?php              $request_username = $_GET["username"];              if(empty($request_username)) {                  echo "username == null";                  exit;              }              $request_key = $_GET["key"];              $time_to_live = 600;              $timestamp = time() + $time_to_live;//失效时间              $response_username = $timestamp.":".$_GET["username"];              $response_key = $request_key;              if(empty($response_key))              $response_key = "code_key"; //constants.py中CEOD_KEY              $response_password = getSignature($response_username, $response_key);              $jsonObj = new Response();              $jsonObj->username = $response_username;              $jsonObj->password = $response_password;              $jsonObj->ttl = 86400;            //此处需配置自己的服务器            $jsonObj->uris= array("stun:webrtc.olcms.com:3478","turn:webrtc.olcms.com:3478?transport=udp","turn:webrtc.olcms.com?transport=tcp");            echo json_encode($jsonObj);          /**            * 使用HMAC-SHA1算法生成签名值            *            * @param $str 源串            * @param $key 密钥            *            * @return 签名值            */        function getSignature($str, $key) {        $signature = "";        if (function_exists('hash_hmac')) {        $signature = base64_encode(hash_hmac("sha1", $str, $key, true));        } else {        $blocksize = 64;        $hashfunc = 'sha1';        if (strlen($key) > $blocksize) {        $key = pack('H*', $hashfunc($key));        }        $key = str_pad($key, $blocksize, chr(0x00));        $ipad = str_repeat(chr(0x36), $blocksize);        $opad = str_repeat(chr(0x5c), $blocksize);        $hmac = pack(        'H*', $hashfunc(        ($key ^ $opad) . pack(        'H*', $hashfunc(        ($key ^ $ipad) . $str        )        )        )        );        $signature = base64_encode($hmac);        }            return $signature;            }            class Response {                  public $username = "";                  public $password = "";                  public $ttl = "";                  public $uris = array("");              }          ?>

运行过程中的问题
1. Failed to start signaling: Failed to execute ‘pushState’ on ‘History’: A history state object with URL ‘http://192.168.6.54/r/198676628’ cannot be created in a document with origin ‘https://192.168.6.54’ and URL ‘https://192.168.6.54/

解决方法1：
房间服务器编译完成后，在/root/apprtc/out/app_engine/js/apprtc.debug.js文件中找到window.history.pushState({‘roomId’: roomId, ‘roomLink’: roomLink}, roomId, roomLink)，把这句话注释掉，重新运行即可。（如果重新编译，需要重新修改）

解决方法2：
在/root/apprtc/src/web_app/js/appcontroller.js文件中找到window.history.pushState({‘roomId’: roomId, ‘roomLink’: roomLink}, roomId, roomLink)，把这句话注释掉，然后重新编译，重新运行房间服务器即可。

回到目录
