Chat problem

[Lutice]

Hello Thanks for your great job. I have a mistake with the chat functionnality . BBB is not on the same server as bbb-live-streaming. I redirect the redis port like this

ssh -L 6379:127.0.0.1:6379 -N -f ssh_user@bbb-server

If I don't do this Redis DB can't be join from outside because the default conf is 127.0.0.1 and I don't want to expose redis to everybody (I can use UFW but I prefer to keep it closed)

In the docker-compose.yml file I have this configuration :

      - BBB_ENABLE_CHAT=true
      - BBB_REDIS_HOST=127.0.0.1
      - BBB_REDIS_CHANNEL=chat
      - BBB_CHAT_NAME=chat

I have this error when I start the docker-compose

livestream from bbb-server

But I have the "same" problem if I start livestream from the bbb-server It's not connection refused but : name or service not known

I see this message : Viewers of the live stream can now send messages to this meeting but I disconnected immediately after

If someone can help me please :)

hi Fabrice, could you solve your issue?

[Lutice]

hello @mtsonline no I don't

[mtsonline]

Fabrice I am not sure if you are trying the correct way ... what do you want to do?

the redis db is on the liveStreaming server and has nothing to do with the bbb server. The only external resource that will have to have access to the redis db is the player where the chat form is situated. you can open the port in the firewall for this server - or change the scripts to use authentication with redis. hth

[Lutice]

I thought the chat form could interact with the bbb-chat, it's not true ? I created a webpage with the livestream and the chat form. If the chat need a redis database to work standalone (without bbb) I need a redis container to run (it's not in the doc), but it's not what I wanted. Fabrice

Fabrice, the chat interacts with the bbb chat, but not via redis. The chat form sends the messages to a redis db hosted within a container. liveStreaming reads the messages from this db and sends it into the bbb chat via the website / html5 client it is logged into.

when you have a look at the docker-compose you will see that a redis db is included there and set to the same network so liveStreaming can interact with this db. all you have to do is set up the chat php script correctly and make sure the redis db (on the liveStreaming server can be reached from this form.

cheers

Can anyone here guide how to "set up the chat php script correctly and make sure the redis db on the liveStreaming server can be reached from this form) ?
