开源视频会议bigbluebutton开发（5）——开发web端,red5应用，桌面共享
开发 BBB-web
Java代码
bbb-conf –setup-dev web
启动grails app
Java代码
cd /home/firstuser/dev/bigbluebutton/bigbluebutton-web/
下载必要的库
Java代码
gradle resolveDeps
使grails监听8888端口
Java代码
grails -Dserver.port=8888 run-app
如果报这样的错误： “Could not resolve placeholder 'apiVersion'“，重新运行上述命令！
开发Red5应用
确保red5/webapps，是可写入的，否则，在部署到Red5上遭遇到许可错误！
Java代码
bbb-conf –setup-dev apps
停止red5
Java代码
sudo /etc/init.d/red5 stop
编译部署 bbb-aps
Java代码
cd /home/firstuser/dev/bigbluebutton/bigbluebutton-apps
gradle resolveDeps
gradle clean war deploy
启动red5
Java代码
cd /usr/share/red5/
sudo -u red5 ./red5.sh
开发 BBB-Voice
Java代码
Stop red5
sudo /etc/init.d/red5 stop
cd /home/firstuser/dev/bigbluebutton/bbb-voice
gradle resolveDeps
Compile and deploy bbb-voice
gradle war deploy
On another terminal window, start Red5
cd /usr/share/red5/
sudo -u red5 ./red5.sh
开发 桌面共享
Java代码
cd /home/firstuser/dev/bigbluebutton/deskshare
gradle resolveDeps
构建应用
Java代码
cd applet
gradle jar
创建一个密匙来签署应用，根据相应的提示输入密码.
Java代码
ant create-signing-key
签署jar文件
Java代码
ant sign-jar
如果报错：
Java代码
sign-jar:
[signjar] Signing JAR: /home/firstuser/dev/bigbluebutton/deskshare/applet/build/libs/bbb-deskshare-applet-0.71.jar to /home/firstuser/dev/bigbluebutton/deskshare/applet/build/libs/bbb-deskshare-applet-0.71.jar as code.signer
[signjar] jarsigner: unable to sign jar: java.util.zip.ZipException: duplicate entry: com/myjavatools/web/ClientHttpRequest.class
[signjar] Enter Passphrase for keystore:
BUILD FAILED
/home/firstuser/dev/bigbluebutton/deskshare/applet/build.xml:70: jarsigner returned: 1
Total time: 3 seconds
输入下面命令，从新编译
Java代码
cd ../common
gradle clean
gradle jar
然后重新签署应用，签署的jar文件位于/home/firstuser/dev/bigbluebutton/deskshare/applet/build/libs/bbb-deskshare-applet-0.8.jar
我们需要把它复制到nginx加载客户端的地方！
如果你同时在开发bbb客户端
Java代码
cp /home/firstuser/dev/bigbluebutton/deskshare/applet/build/libs/bbb-deskshare-applet-0.8.jar /home/firstuser/dev/bigbluebutton/bigbluebutton-client/client
如果没有开发客户端，nginx会从默认位置加载，因此
Java代码
cp /home/firstuser/dev/bigbluebutton/deskshare/applet/build/libs/bbb-deskshare-applet-0.8.jar /var/www/bigbluebutton/client/
构建服务器端的组件
Java代码
cd /home/firstuser/dev/bigbluebutton/deskshare/app
Compile
gradle war
Copy over to Red5
gradle deploy
Stop red5
sudo /etc/init.d/red5 stop
cd /home/firstuser/dev/bigbluebutton/bigbluebutton-apps
Compile and deploy bbb-apps
gradle war deploy
On another terminal window, start Red5
cd /usr/share/red5/
sudo -u red5 ./red5.sh
错误解决
如果显示 "Welcome to Nginx"页面，检查nginx里bbb是否正常，你可以看到bbb在/etc/nginx/sites-enabled
如果bbb不正常，那就启用它
Java代码
sudo ln -s /etc/nginx/sites-available/bigbluebutton /etc/nginx/sites-enabled/bigbluebutton
sudo /etc/init.d/nginx restart
