Cannot get Greenlight to work - Please help!!!!

[Annaliza Marks]

I am trying to install Greenlight on my BigBlueButton server.  Whenever I type "thunderbird.glenville.edu" it goes to thunderbird.glenville.edu/b but I get the file not found.  When I manually type https://thunderbird.glenville.edu/bigbluebutton/, I get this error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
      <response><returncode>SUCCESS</returncode><version>1.1</version></response>


I am not sure what I am doing wrong.  I had it working with the api demo but now that I'm trying to install Greenlight, I am having issues.  Here's my bbb-conf --check:

gsc@thunderbird:/etc/bigbluebutton/nginx$ sudo bbb-conf --check

gsc@thunderbird:/etc/bigbluebutton/nginx$


Also, when I try this command: 

docker run --rm bigbluebutton/greenlight cat ./scripts/greenlight.nginx > /etc/bigbluebutton/nginx/greenlight.nginx

I get this error:

gsc@thunderbird:/etc/bigbluebutton/nginx$ sudo docker run --rm bigbluebutton/greenlight cat ./scripts/greenlight.nginx > /etc/bigbluebutton/nginx/greenlight.nginx
-bash: /etc/bigbluebutton/nginx/greenlight.nginx: Permission denied
gsc@thunderbird:/etc/bigbluebutton/nginx$

I get permission denied.

I eventually found a base greenlight.nginx file and added it to the /etc/bigbluebutton/nginx folder and the /scripts/ folder and added this text:

+# Routes requests to Greenlight based on the '/b' prefix

+

+location /b {

+ proxy_pass http://127.0.0.1:5000;

+ proxy_set_header Host $host;

+ proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

+ proxy_set_header X-Forwarded-Proto $scheme;

+ proxy_http_version 1.1;

+}

+

+location /b/cable {

+ proxy_pass http://127.0.0.1:5000;

+ proxy_set_header Host $host;

+ proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

+ proxy_http_version 1.1;

+ proxy_read_timeout 6h;

+ proxy_send_timeout 6h;

+ client_body_timeout 6h;

+ send_timeout 6h;

+}

Should I have done something different? What can I do to fix this?  Please help!!  Thank you!!!

The command: 

sudo docker run --rm --env-file env bigbluebutton/greenlight rake conf:check


Produces this:

Checking environment: Passed
Checking Connection: Passed

Hi Annizila,

Looks like you have a public/private IP address.  Try the suggestion here

 http://docs.bigbluebutton.org/install/green-light.html#launching-greenlight-in-the-host-network

and let us know if that gets you going.

Regards,... Fred

Thank you Fred! I have gone through those steps to no avail. If I'm understanding correctly, does that mean I can't have a stand alone (public) and LTI integration (private) with Blackoard?

[Fred Dixon]

Hi,

You can have both.  I'm assuming that the LTI integration is working.  The LTI integration is simply an application that accepts an LTI launch and then turns around and talks to the BigBlueButton server using its API.

GreenLight, in a similar manner, is a rails application that presents a web interface and then turns around and talks with the BigBlueButton API.

> docker run --rm --env-file env bigbluebutton/greenlight rake conf:check

This says that GreenLight, running in a Docker container can communicate with the BigBlueButton server.

However, when a user connects to

  

  https://thunderbird.glenville.edu/b

the nginx proxy isn't forwarding it to the GreenLight server.  GreenLight is running in Docker, so it might not be reachable by 127.0.0.1 (or it might not be running).

If you do 

 docker ps

Do you see GreenLight running?

Regards,... Fred

Can you try connecting to greenlight via telnet.  On the server type

  telnet 127.0.0.1 5000

and, if GreenLight is listening, you should see

# telnet 127.0.0.1 5000
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

If you don't have telnet installed, do 

  sudo apt-get install telnet

This will test if GreenLight is listening to port 5000.

So it is nginx not communicating.  How can I fix this?

Thank you so much, Fred!!

It says that it connected....

"Connected to 127.0.0.1 5000"

(Connection closed by a foreign host - should this be a concern?)

gsc@thunderbird:~$ telnet 127.0.0.1 5000

Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

Connection closed by foreign host.
gsc@thunderbird:~$

Hi,

Can you now try

 telnet thunderbird.glenville.edu 5000

and see if you get a connection.  It's OK if you get a "Connection closed by foreign host" after a few seconds.

I just tested demo1.jsp on your server,  it takes me to join the flash client starts to load it and then quickly i redirect to /b which does a 404.

So the base Nginx config for the flash client is not working either.

I would comment out the greenlight nginx rules, and try to get the demo pages back working.

Then try to reapply

Oh no, it didn't work!

gsc@thunderbird:~$  telnet thunderbird.glenville.edu 5000
Trying 10.102.2.164...
Trying 129.71.82.164...
telnet: Unable to connect to remote host: Connection refused
gsc@thunderbird:~$

[Annaliza Marks]

Thank you Stephen!  Where would I do that? In greenlight.nginx?

[HostBBB.com]

Looks like port 5000 is working, so greenlight is running on 127.0.0.1.   Dont believe it needs to be accessing externally since nginx is the proxy.

If you  

sudo mv greenlight.nginx greenlight.nginx-dontuse

and restart

 sudo service nginx restart

then go to your server /demo/demo1.jsp and see if the meeting loads in the flash client without kicking you out.

If not, then you have made some other change in nginx config that is causing the issue.

Stephen

I think this is the issue:

mv: cannot stat 'greenlight.nginx': No such file or directory

I had to manually create a greenlight.nginx because I got this error (I added to the original question but since we haven't "talked" about it, I assumed it was ok.  This is what I posted earlier:
