##
## NOTE CONFIGURE SHARED DRIVE BEFORE MAKING THE BELOW CHANGE
make sure that you symlink streams folder as mentioned below
ln -sf <shared_disl>/streams /usr/share/red5/webapps/video
mount <shared_disl>/streams /usr/share/red5/webapps/recording (make sure its not sym link but mounted)
Streams should have following permission;
expdev01/expprodl:red5 streams/uploaded (for this folder alone)
For all other files inside streams its red5:red5
Also note that you may have to modify deploybbbclient.sh script MEETING_URL and sed search string for Learnexa APP IP according to ~/dev/bigbluebutton/bigbluebutton-client/src/conf/config.xml, as in "siteBaseUrl".

./deploybbbclient.sh
