Instructions for an edX production server configuration

[John Jarvis]

Lately we have been getting many requests for help with configuration. 

I just updated the edx/configuration wiki with instructions for how to install edX on a single server which is a good place to start for a production setup.

This uses the same provisioning scripts that edX is using and should run cleanly on any 12.04 virtual machine.

https://github.com/edx/configuration/wiki#installation

I'll be adding more services to the single instance stack over the next week or two (for now it only includes the LMS and Studio). 

If you have any questions about the setup please reply to this thread or ask in #edx-code on freenode.

Hello John,

According to my notes, contributions will be sought for l10n and graders. For l10n, I think this is a good configuration. What about providing a way to confirm the servers are operational? I find sudo netstat -lnptu useful but you might know of an even better way. 

With respect to graders, it is my understanding you'll need edx-ora and associated servers. Is that right?

[John Jarvis]

Hi John,

To confirm that it's working you can connect your web browser to the LMS running on port 80 or studio which defaults to port 18010.

Right now the edx_sandbox.yml has the following in its roles: section

  roles:

    - common

    - nginx

    - edxlocal

    - edxapp

If you change it to 

  roles:

    - common

    - nginx

    - edxlocal

    - edxapp

    - ora

It will check out the ora/ease repo, drop the upstart scripts and start the service.  

I'm not including yet until I confirm that it's working properly but I believe it should be.

-John

[John]

Hello John,

Thanks for extended the example to include edx-ora.  

With respect to confirming the install, I much prefer netstat as it gives feedback on all server (e.g., db, web, queue).

Hello John,

I was trying to install edX on a Virtual Machine which runs Ubuntu 12.04 desktop x64.

Things was good at first. I finished these two step without error:

• On the new server, install ansible:

  sudo pip install ansible
  

• Using ansible, clone the configuration repo to a temporary directory

  sudo ansible all -c local -i "localhost," --limit "localhost:127.0.0.1"  \
  -m git -a "repo=https://github.com/edx/configuration dest=/var/tmp/configuration"

But when I was trying run the edx_sandbox.yml playbook, I met a problem. 

After run this step:

sudo ansible-playbook -c local --limit "localhost:127.0.0.1" \
edx_sandbox.yml -i "localhost,"

The result turns out to:

TASK: [Install role-independent useful system packages] *********************** 

changed: [localhost]

TASK: [Create log directory] **************************************************

TASK: [Create alias from app_base_dir to the log_base_dir] ********************

           to retry, use: --limit @/var/tmp/ansible/edx_sandbox.retry

localhost                  : ok=15   changed=9    unreachable=0    failed=1   

Could you help me to deal with this error?

Hi Duoglas,

Are you running ansible-playbook from the /var/tmp/configuration/playbooks directory?

-John

[Duoglas Du]

yes,   running ansible-playbook from the /var/tmp/configuration/playbooks directory.

For the edx_sandbox.yml use the absolute path. Worked for me.

From a clean installation of Ubuntu Server 12.04 64bits, I also needed to manually add some packages. Before running the playbook I recommend to execute the following commands to avoid errors:

sudo apt-get update
sudo apt-get upgrade 
sudo reboot 

sudo apt-get install python-pip python-dev build-essential 
sudo pip install --upgrade pip 
sudo pip install --upgrade virtualenv 

sudo apt-get install software-properties-common 
sudo apt-get install python-software-properties 

sudo apt-get install git

After that, I only got an error in the task "check if django can update cms templates" but I think it has to do with the recent removal of template modules.

Once installed the production server, is there any easy way to apply new fixes and changes to the edx applications?

[Duoglas Du]

Using the absolute path for edx_sandbox.yml works!   Thank you so much.

Since I am running my test server in China ,   some required packages seems to be unaccessible. 

I fixed it by using a proxy.

What is the default user/password for the django admin site?

This was caught recently and should be fixed on the master branch of the configuration repo.

We don't set one up by default.

[Daoud Salma]

Hello,

when I run:  

it fails :

In fact other errors occur but ignored:

...ignoring

I have another question about having edx work behind a proxy: should I spesify the ip address/ dns ? 

[Puntxo]

> What is the default user/password for the django admin site?

We don't set one up by default.

Hi John, I'm referring to the admin site in http://localhost:18010/admin

Just another question, ¿how could I start up the discussion service in the production server?

Best regards 

[Anurag Ramdasan]

During the syncdb command, you must have created a user. Django assumes that to be the default admin.

[Puntxo]

Thank you, but the whole installation and configuration is made with ansible. I've reviewed the playbooks trying to find that information with no success.

[John Jarvis]

The admin user is optional, we don't set one up by default.

The relevant playbook for the syncdb is https://github.com/edx/configuration/blob/master/playbooks/roles/edxapp/tasks/deploy.yml

- name: syncdb and migrate
  shell: sudo -u www-data SERVICE_VARIANT=lms /opt/edx/bin/django-admin.py syncdb --migrate --noinput --settings=lms.envs.aws --pythonpath=/opt/wwc/edx-platform
  when: migrate_db is defined and migrate_db|lower == "yes"

[Puntxo]

Thank you again John. So I'll try to create a super user with django-admin to access to the admin site. I find it very useful for doing some maintenance tasks.

[John Jarvis]

> msg: Failed to find required executable add-apt-repository

Are you installing the platform on an ubuntu VM?

> In fact other errors occur but ignored:

The ignored error is expected.

[Puntxo]

> msg: Failed to find required executable add-apt-repository

You can install the add-apt-repository command by running:

sudo apt-get install python-software-properties 

[na...@edx.org]

Based on John's instructions, I made a small script to get edX installed on a remote Ubuntu server. You can execute the script with this one command:

wget https://tinyurl.com/edx-install && ssh -i ~/.ssh/<yourkey>.pem ubuntu@ec2-<x.x.x.x>.compute-1.amazonaws.com 'bash -s' < edx-install

This will:

1) download the edx-install script (which is hosted at gist.github.com)

2) execute that script via SSH using your private key to login to the remote server

3) show the results on your local terminal including the Ansible playbook output

This is assuming you are using Amazon EC2 where ~/.ssh/yourkey.pem is the private key you're using with AWS, and ec2-x-x-x-x.compute-1.amazonaws.com is the public hostname for your EC2 server.

If you're using some hosting provider other than AWS, you'd just substitute that with the IP address of your server.

Hi John,

When I ran the following instruction on a newly installed Ubuntu server

ansible-playbook -c local --limit "localhost:127.0.0.1" /var/tmp/configuration/playbooks/edx_sandbox.yml \
-i "localhost," -e 'cms_nginx_port=80  lms_preview_nginx_port=80  c_lms_base=example.com \
c_preview_lms_base=preview.example.com'

the following error occurred

           to retry, use: --limit @/var/tmp/ansible/edx_sandbox.retry

Is there something wrong with the playbooks?

[Wentao Han]

BTW, the following instruction works well.

cd /var/tmp/configuration/playbooks

sudo ansible-playbook -c local --limit "localhost:127.0.0.1" \
./edx_sandbox.yml -i "localhost,"

[John Jarvis]

Hi Wentao,

Are you still seeing this error or did you mean that it is working now?'

The error earlier points to :

jinja2_extensions=jinja2.ext.do

not being set in your ansible config, if you run it out of the playbooks directory it should be set since there is an ansible.cfg there.

-John

[Wentao Han]

Yes, it's due to the incorrect working directory.  It should be run under playbooks/.

[Daoud Salma]

Hi John,

I successfully   finished edx production mode install.

During the script execution I notice that the comment service is being installed.

but when I access edx lms , I got the discussion page NOT FOUND.

should I install it from https://github.com/edx/edx-platform/blob/master/doc/discussion.md

Or is it installed and I can start it some how?

Regards 

salma

Hi John, in reference to this issue on edx configuration, i tried deploying again after merging #199 and #200 and this error came up:

ASK: [stop edxapp services] **************************************************

Any attempt to access lms or studio through the browser results in a 502 as follows:

 Hey Puntxo, Can you please tell me how you created Super user for the Django Administration.

[Ryan Riley]

Thanks for putting this together!

I've got this up and running in a VM and am currently playing around with it.  I'm planning to use edX to run a hybrid course for a lab class I'm teaching.  I have a small amount of Django experience, but no Ruby or Node experience.

I have a few questions about this specific ansible configured machine that I was hoping someone could help me with:

1. How to disable registrations for the CMS?  I don't want random people to be able to register and create courses on the machine.
2. I can't seem to run any of the rake commands.  I'm guessing its something about ruby virtual environments that I don't understand.  Do I need to enter a specific virtual environment first to make sure that the proper version of rake is run, etc?

Thanks

Ryan

[Chris Dodge]

In order to restrict registrations, there's Enrollment Start and End settings on courses (look on the Course Settings page in Studio). All you have to do is set both those in the past - then you can manually enroll students in the LMS Instructor dashboard.

[Ryan Riley]

Thanks, that's helpful to know, too!  Its not quite what I was wondering, though.  How do I disable registrations for studio?  Right now, by default, anyone can make an account in studio and start creating courses.  Is there a way to disable this?

Thanks

Ryan

Hello Douglas,

I'm facing the same issue as you gone through. Could you please tell me what exactly is the absolute path for edx_sandbox.yml ?

Thanks in Advance.
