Having trouble connecting to LMS discussion forum getting Errors

[Juanito]

Hello,

I have two servers setup, one for the apps (lms,cms,forum, etc..), and one for data (mysql & mongodb). Currently, lms and studio are working and talking to the data store server. When I click on forum discussion on lms, it gives me error 500 (THERE HAS BEEN A 500 ERROR...)

Here is lms log

I saw that /edx/var/forum/forum.sock was not there, so for testing I  manually created /edx/var/forum/forum.sock and set permission www-data but I now get connection refused.

The upstream string looks really weird (http://unix:/edx/var/forum/forum.sock:/) 

Here is my forum nginx conf:

upstream forum_app_server {

  server unix:/edx/var/forum/forum.sock fail_timeout=0;

}

server {

  server_name forum.*;

  listen 80 ;

  client_max_body_size 1M;

        proxy_set_header Host $http_host;

    proxy_redirect off;

    proxy_pass http://forum_app_server;

  }

}

I am not sure what is going on, if any have ideas or clues, please help me.

Thanks

Check to make sure the comment service is running (host/port) or have a look at these variables in your settings :

COMMENTS_SERVICE_URL

COMMENTS_SERVICE_KEY

These are the default:

EDXAPP_COMMENTS_SERVICE_URL:  'http://localhost:18080'

EDXAPP_COMMENTS_SERVICE_KEY:  'password'

[Juanito]

Thanks for that tip, it really gave me some hope. 

I did forget to specify the URL,

I ran the playbook again, and verified they are set in /edx/etc/edxapp/{lms,cms}.env.yaml:

COMMENTS_SERVICE_KEY: password

COMMENTS_SERVICE_URL: http://forum.mydomain.org

I still get

Any more ideas?

[Trinh Nguyen]

Try to restart the comment service:

supervisorctl restart forum

If it does not work, please check your unicorn process to see if it is running and with what configuration (unicorn.rb or unicorn_tcp.rb).

Then check your forum data dir permissions.

[Trinh Nguyen]

Forum data dir permissions should be set as following:

Owner: www-data

Group: www-data

[Juanito]

Hi Trinh

I restarted forum, and it stopped and started again.

I can see that unicorn.rb is running

www-data  4885 13.2  1.9 315652 75484 ?        Sl   02:35   0:02 ruby /edx/app/forum/cs_comments_service/bin/unicorn -c config/unicorn.rb

My form data dir /edx/var

drwxrwxrwx  2 www-data         www-data      4096 Apr  6 02:38 forum/
-rw-r--r--  1 www-data         www-data         5 Apr  6 02:39 forum/forum_unicorn.pid

forum.sock is not created though. I should not have to manually create it right?

I was browsing through roles/forum/defaults/main.yml and I wasn't sure what these were for:

FORUM_LISTEN_HOST: "0.0.0.0"

FORUM_LISTEN_PORT: "4567"

FORUM_USE_TCP: false

Any ideas?

Thanks so much

[Trinh Nguyen]

Could you show me the results of:

netstat -anltp | grep LISTEN

and also the logs of comment service.

Based on Mongo::Error::NoServerAvailable It seems it saying it can't connect to mongodb.

I logged on to my datastore server checked list of mongodb. I am not sure what is supposed to be there but here is the db list, but it looks like cs_comments_service supposed to be there right?

edxapp  0.078GB

I am not sure at what point during the ansible installation it gets created. This is my custom vars related to FORUM, pretty much default except HOSTS

FORUM_MONGO_USER: "cs_comments_service"

FORUM_MONGO_PASSWORD: "password"

FORUM_MONGO_HOSTS:

  - "172.16.2.10"

FORUM_MONGO_TAGS: !!null

FORUM_MONGO_PORT: "27017"

FORUM_MONGO_DATABASE: "cs_comments_service"

FORUM_MONGO_USE_SSL: false

[Trinh Nguyen]

So then check your mongodb server. Did you try to connect to mongodb at 172.16.2.10 from your edx apps server?

mongo 172.16.2.10:27017/cs_comments_service -u cs_comments_service -p password

The mongodb server should allow remote host to connect:

0.0.0.0:27017

I used to experience a case where the mongodb user had been deleted unknowingly (you can read about it here). I then had to create the user again for my edx instance working.

Yes, I can connect to mongo. I set the mongodb to bind to 0.0.0.0 and opened up the port 27017 on my data machine

mongo 172.16.2.10:27017/cs_comments_service -u cs_comments_service -p password

MongoDB shell version: 2.0.4

connecting to: 172.16.2.10:27017/cs_comments_service
> db

cs_comments_service 
>show dbs

admin 0.078125GB

edxapp 0.078125GB

local 0.078125GB

> show users

> show collections

It's odd that cs_comments_service doesn't show up when I execute show dbs.

Anywhere else I should check? :)

Thanks.

Try to restart mongodb:

sudo service mongod restart

If it does not work, try to remove the lock file and start again:

sudo rm /edx/var/mongo/mongodb/mongod.lock

(default location)

Hey Trinh,

Thanks for those suggestion, but unfortunately nothing changed. When I check the supervisor log for forum, it keeps logging this periodically. Here is a snippet:

`select_server': No server is available matching preference: #<Mongo::ServerSelector::Primary:0x0000000485d348 @options={"mode"=>:primary, "database"=>:cs_comments_service_development, "write"=>{"w"=>1}, "read"=>{"mode"=>:primary}, "max_retries"=>1, "retry_interval"=>0, "timeout"=>0.5, "ssl"=>false}, @tag_sets=[], @server_selection_timeout=30> (Mongo::Error::NoServerAvailable)

Not sure _development came from...

[Trinh Nguyen]

Oke so now check out all of your mongodb configuration:

server-vars.yml

lms/cms.env.json

...

[Juanito]

Hey Trinh,

I believe it works now! Thanks so much for helping me troubleshoot.

I was searching for the keyword "cs_comments_service" on /edx/app/forum/cs_comments_service/config/mongoid.yml it appears the database points to cs_comments_service_development when in development, so I went and checked for the forum environment to see what triggers this and I found couple forum variables:

FORUM_SINATRA_ENV: "development"

FORUM_RACK_ENV: "development"

I changed it to production and ran ansible and forum stated working.

I am not sure what those two ENV mean, but for now since it working I'll take a break.

Thanks so much again Trinh

[Trinh Nguyen]

Oh, that's great Juanito!

[Trinh Nguyen]

BTW, that the default configuration for cs_comment_service:

https://github.com/edx/configuration/blob/master/playbooks/roles/forum/defaults/main.yml

[Trinh Nguyen]

They are settings of SINATRA, the web application framework on which the comment service was built on. You can have a look this for a better understanding: http://www.sinatrarb.com/configuration.html.

[Juanito]

Ah, I see. So far forum working great.

Thanks so much again.

I am sorry to bother but it is necessary. Please

Hi Nishant,

Just a thought: have you set FORUM_SINATRA_ENV and FORUM_RACK_ENV variables to "production" in your server-vars.yml?

@Juanito, did you had any success when you were installing ecommerce from the ansible-playbook at /var/tmp/configuration/playbook/edx-east/ecommerce.yml

I installed ecommerce the same way but it is not working. Do you have any way to install ecommerce on native installation

[Nishant Dixit]

I am stuck for more than 2 months now and i still can't get it working. So, if you guys could take a look at these, it would save me a lot of trouble. BTW Trinh, I follow you on Stack overflow and your answers are great
