1. Setup BBB 1.1 - http://docs.bigbluebutton.org/install/install.html#installing-bigbluebutton-11

2. Setup BBB 1.1 development environment - http://docs.bigbluebutton.org/dev/setup.html

Verify that the BBB app launches fine with the client loading from development directory.

4. Changes to the config files -

sudo vi /var/lib/tomcat6/webapps/bigbluebutton/WEB-INF/classes/bigbluebutton.properties

maxNumPages=5000
defaultWelcomeMessage=  //(just leave it empty)
defaultWelcomeMessageFooter= //(just leave it empty)
defaultClientUrl=${bigbluebutton.web.serverURL}/client/LiveEvent.html
beans.presentationService.defaultUploadedPresentation=${bigbluebutton.web.serverURL}/DefaultMockPresentationXYZ.pdf

cd /var/www/bigbluebutton-default/ 
sudo touch DefaultMockPresentationXYZ.pdf

sudo vi /etc/bigbluebutton/nginx/client.nginx

//change location /client/BigBlueButton.html {  -> location /client/LiveEvent.html {

sudo vi /etc/nginx/sites-enabled/bigbluebutton
client_max_body_size 200m

sudo vi /etc/bigbluebutton/nginx/web.nginx
client_max_body_size 200m;

sudo vi /etc/bigbluebutton/nginx/client.nginx
root /var/www/bigbluebutton => root /home/expbbbp/dev/bigbluebutton/bigbluebutton-client;

Make sure the proper ngnix configuration and add the ssl certificate path

5. Checkout client code from svn co https://repos.exphosted.com/svnrepos/collaboration/bbb/trunk/ and place it at <home of bbb user>/dev/bigbluebutton/bigbluebutton-client

6. Client config changes - Change config.xml file ( <home of bbb user>/dev/bigbluebutton/bigbluebutton-client src/conf/config.xml)
(It better to symlink this file has this is full of IP configuration)

     // Make this IP/URL changes based on the environment
     //Replace the ip (For instance - 192.168.2.240) 192.168.2.240 with this machine’s hostname(devcollab02.learnexa.com)
     sed -i s/http://192.168.2.184/devcollab02.learnexa.com/g bigbluebutton-client/src/conf/config.xml
     
     //Replace the ip http://192.168.2.154:3000 with learnexa url machine’s hostname
     sed -i s/http://192.168.2.154:3000/https://dev01.learnexa.com/g bigbluebutton-client/src/conf/config.xml

7. Compile client and restart bbb

cd <home of bbb user>/dev/bigbluebutton/bigbluebutton-client
ant 
ant locales
sudo bbb-conf --restart

Note - Steps 5-7 will be taken care by deploy script once the initial setup is done.

8. Setup freeswitch

9. Edit Learnexa rails app bigbluebutton.yml settings to place the details of bigbluebutton URL and salt. Restart learnexa rails app.

10. Whenever we change the collaburl in learnexa(config/bigbluebutton.yml) then the corresponded extension needs to be updated in learnexa

  1. Incase voice extension is changed in BBB setup then old extension needs to be deleted and the new extension needs to be added in the database via running the following backfill tasks(voice_extensions.rake) 
  
  a. First change the extention which is needs to be inactivated in(db/voice_extensions_inactive.csv) and run 
     bundle exec rake voice_extensions:inactivate 
  b. Delete the extension which are all inactive by running
     bundle exec rake voice_extensions:delete_inactive 
  c. Add the new extension which is needs to be added in (db/voice_extensions.csv) and run 
     bundle exec rake voice_extensions:populate
 

11. Edit public/crossdomain.xml settings to allow cross domain ajax requests from BBB machine URL.

12. Install the code signing certificate

1. https://wiki.exphosted.com/doku.php?id=install_code_signing_certificate_to_learnexa_live_event_screen_share

13. Get the deployment script from svn based on the environment and make the required url changes based on the environments like(COLLAB_URL. etc..)

1. Change /usr/share/red5/conf/red5-common.xml to replace queueThreshold and deplayWrite values.

<bean id="fileConsumer" scope="prototype" lazy-init="true" class="org.red5.server.stream.consumer.FileConsumer"> 
   <property name="delayWrite" value="false"/> 
   <property name="queueThreshold" value="14400"/> 
</bean>

Just running the deploy script after below mentioned changes is fine.

1) Edit / Verify Hosts. Check whether /etc/hosts has an entry mapping this machine's FQDN to 127.0.0.1 2) Mount “streams” brick.

touch /usr/share/red5/websapps/video/streams/error-if_you_see_this
mount.glusterfs <FQDN>:/streams /usr/share/red5/websapps/video/streams

3) Verify that it is correctly mounted and add to fstab.

1) Replace all the URLs in sed commands to update the /src/conf/config.xml

2) Make a directory as bbb user.

 mkdir -p ~/dev/srctrunk 

3) Change the value of BBBDIR to “/home/<bbb user>/dev/bigbluebutton”

1) Update the bbb user home directory and path to bbb directory correctly.

Bigbluebutton1.1 installation steps URL is given below

http://docs.bigbluebutton.org/install/install.html
https://wiki.exphosted.com/doku.php/setup_and_deploy_bbb_11

Need to follow the below steps in the “http://docs.bigbluebutton.org/install/install.html”

1. install
2. Setup Development Environment

swap space creation ( if the collab server contain 4GB, we need to create swap space )

https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04

sudo apt-get install haveged
sudo apt-get update
sudo apt-get dist-upgrade
reboot 
sudo apt-get update

Add the user odeploy as sudo users

visudo
odeploy ALL=(ALL) NOPASSWD: ALL

Bigbluebutton clone from git

adduser expbbbp
su - expbbbp
sudo apt-get install git
sudo git clone https://github.com/bigbluebutton/bigbluebutton.git
chmod -R 775 dev
cd ~/dev
(/home/expbbbp/dev)
sudo chown -R expbbbp:expbbbp tools
sudo chown -R expbbbp:expbbbp bigbluebutton
sudo chmod 775 bigbluebutton

https://wiki.exphosted.com/doku.php/recorder_setup_bbb_v_1.0?s[]=glusterfs&s[]=3&s[]=7&s[]=6

IMPORTANT ( Development tools needs to be installed as “expbbbp” user )

 add-apt-repository ppa:gluster/glusterfs-3.8
 apt-get install glusterfs-client glusterfs-server
 mkdir -p /data/brick1/

 add the below entry
 vi /etc/hosts
 10.138.84.57 odevcollab01_https
 cd /mnt
 mkdir crossbow
 /usr/sbin/gluster volume create crossbow transport tcp 10.138.84.57:/data/brick1 force
 gluster volume start crossbow force
 /sbin/mount.glusterfs odevcollab01_https:/crossbow /mnt/crossbow
 mkdir -p /usr/share/red5/webapps/recorder/streams
 cd /usr/share/red5/webapps/
 chown -R red5:red5 recorder 


 cp /soft/collab_bin.zip /home/expbbbp
 chown -R expbbbp:expbbbp bin
 apt-get install subversion
 cd /home/expbbbp/dev/bigbluebutton
 

svn co https://repos.exphosted.com/svnrepos/collaboration/bbb/trunk 
mv trunk bigbluebutton-client_20180320102919
chown -R expbbbp:expbbbp bigbluebutton-client_20180320102919

cd /home/expbbbp/bin
vi deploybbbclient.sh

do perform find and replace

:%s/qacollab01.learnexa.com/odevcollab01.learnexa.com/g 

and changes the APPURL as 

   APPURL="dev.learnexa.com"

once done the changes, run the script

  ./deploybbbclient.sh

if demo is not working ( http://hostname/demo/demo1.jsp ) after ran “deploybbbclient.sh” http 500 error ( java.lang.NullPointerException )

 sudo service redis-server restart

 Try the following

 sudo service redis-server restart

 sudo bbb-conf --check

If you still see issues with the redis server, try the following

sudo service redis-server stop
sudo mv /var/lib/redis/redis.rdb /var/lib/redis/redis.rdb_old
sudo service redis-server start
