some times i got start-up unsuccessful problem when i install BigBlueButton in Digital ocean, when i got that error i can drop that BigBlueButton installed droplet and create a new instance(Droplet), install the  BigBlueButton in it, its start-up is successful and working fine, i don't know why i have got that error some times.

Gopiraju ,

What does unsuccessful mean?   If you are starting from a predefined image the IP may be changing on restart which requires config changes.

If you do sudo bbb-conf --check on non working instance and post results we can quickly tell what the issue is.

Also if your trying to run on less than <2gb Ram you will have intermittent issues...  BBB needed 4gb

Stephen

when i execute this command "cat /etc/lsb-release" i get following  result

DISTRIB_ID=Ubuntu

DISTRIB_RELEASE=14.04

DISTRIB_CODENAME=trusty

DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS"

and size of the droplet as follows

4GB RAM

60GB SSD Disk

Ubuntu 14.04 64bit

With some providers, Digital Ocean being one of them, the combination of Ubuntu Distro and virtualization causes Tomcat to error out the first time it starts, and take a few minutes to start tomcat/red5 on subsequent restarts.

You see it in the tomcat catalina logs the time to get randon number is often 300secounds.

The fix for this is:

vi /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/java.security

change

securerandom.source=file:/dev/urandom

to

securerandom.source=file:/dev/./urandom

Now run sudo bbb-conf --clean and you will see bigbluebutton connect in 3-4 ....  instead of .......................................................................................................................

Your good to go after this.

We added entry in troubleshooting installation for more help with this issue.

  http://docs.bigbluebutton.org/install/install.html#tomcat7-takes-a-long-time-to-startup

 

As an alternative to java.security, you can install havaged to provide additional entropy to the server.

  sudo apt-get install haveged
