1. Welcome

This page is created for MediaCMS administrators that are responsible for setting up the software, maintaining it and making modifications.

2. Server Installation

The core dependencies are Python3, Django3, Celery, PostgreSQL, Redis, ffmpeg. Any system that can have these dependencies installed, can run MediaCMS. But we strongly suggest installing on Linux Ubuntu (tested on versions 20, 22).

Installation on an Ubuntu system with git utility installed should be completed in a few minutes with the following steps. Make sure you run it as user root, on a clear system, since the automatic script will install and configure the following services: Celery/PostgreSQL/Redis/Nginx and will override any existing settings.

Automated script - tested on Ubuntu 20, Ubuntu 22 and Debian Buster

mkdir /home/mediacms.io && cd /home/mediacms.io/
git clone https://github.com/mediacms-io/mediacms
cd /home/mediacms.io/mediacms/ && bash ./install.sh

The script will ask if you have a URL where you want to deploy MediaCMS, otherwise it will use localhost. If you provide a URL, it will use Let's Encrypt service to install a valid ssl certificate.

Update

If you've used the above way to install MediaCMS, update with the following:

cd /home/mediacms.io/mediacms # enter mediacms directory
source  /home/mediacms.io/bin/activate # use virtualenv
git pull # update code
pip install -r requirements.txt -U # run pip install to update
python manage.py migrate # run Django migrations
sudo systemctl restart mediacms celery_long celery_short # restart services

Update from version 2 to version 3

Version 3 is using Django 4 and Celery 5, and needs a recent Python 3.x version. If you are updating from an older version, make sure Python is updated first. Version 2 could run on Python 3.6, but version 3 needs Python3.8 and higher. The syntax for starting Celery has also changed, so you have to copy the celery related systemctl files and restart

# cp deploy/local_install/celery_long.service /etc/systemd/system/celery_long.service
# cp deploy/local_install/celery_short.service /etc/systemd/system/celery_short.service
# cp deploy/local_install/celery_beat.service /etc/systemd/system/celery_beat.service
# systemctl daemon-reload
# systemctl start celery_long celery_short celery_beat

Configuration

Checkout the configuration section here.

Maintenance

Database can be backed up with pg_dump and media_files on /home/mediacms.io/mediacms/media_files include original files and encoded/transcoded versions

3. Docker Installation

Installation

Install a recent version of Docker, and Docker Compose.

For Ubuntu 20/22 systems this is:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Then run as root

git clone https://github.com/mediacms-io/mediacms
cd mediacms

The default option is to serve MediaCMS on all ips available of the server (including localhost). If you want to explore more options (including setup of https with letsencrypt certificate) checkout Docker deployment section for different docker-compose setups to use.

Run

docker-compose up

This will download all MediaCMS related Docker images and start all containers. Once it finishes, MediaCMS will be installed and available on http://localhost or http://ip

A user admin has been created with random password, you should be able to see it at the end of migrations container, eg

migrations_1     | Created admin user with password: gwg1clfkwf

or if you have set the ADMIN_PASSWORD variable on docker-compose file you have used (example docker-compose.yaml), that variable will be set as the admin user's password

Update

Get latest MediaCMS image and stop/start containers

cd /path/to/mediacms/installation
docker pull mediacms/mediacms
docker-compose down
docker-compose up

Update from version 2 to version 3

Version 3 is using Python 3.11 and PostgreSQL 15. If you are updating from an older version, that was using PostgreSQL 13, the automatic update will not work, as you will receive the following message when the PostgreSQL container starts:

db_1              | 2023-06-27 11:07:42.959 UTC [1] FATAL:  database files are incompatible with server
db_1              | 2023-06-27 11:07:42.959 UTC [1] DETAIL:  The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.2.

At this point there are two options: either edit the Docker Compose file and make use of the existing postgres:13 image, or otherwise you have to perform the migration from postgresql 13 to version 15. More notes on https://github.com/mediacms-io/mediacms/pull/749

Configuration

Checkout the configuration docs here.

Maintenance

Database is stored on ../postgres_data/ and media_files on media_files/

4. Docker Deployment options

The mediacms image is built to use supervisord as the main process, which manages one or more services required to run mediacms. We can toggle which services are run in a given container by setting the environment variables below to yes or no:

ENABLE_UWSGI
ENABLE_NGINX
ENABLE_CELERY_BEAT
ENABLE_CELERY_SHORT
ENABLE_CELERY_LONG
ENABLE_MIGRATIONS

By default, all these services are enabled, but in order to create a scaleable deployment, some of them can be disabled, splitting the service up into smaller services.

Also see the Dockerfile for other environment variables which you may wish to override. Application settings, eg. FRONTEND_HOST can also be overridden by updating the deploy/docker/local_settings.py file.

See example deployments in the sections below. These example deployments have been tested on docker-compose version 1.27.4 running on Docker version 19.03.13

To run, update the configs above if necessary, build the image by running docker-compose build, then run docker-compose run

Simple Deployment, accessed as http://localhost

The main container runs migrations, mediacms_web, celery_beat, celery_workers (celery_short and celery_long services), exposed on port 80 supported by redis and postgres database.

The FRONTEND_HOST in deploy/docker/local_settings.py is configured as http://localhost, on the docker host machine.

Server with ssl certificate through letsencrypt service, accessed as https://my_domain.com

Before trying this out make sure the ip points to my_domain.com.

With this method this deployment is used.

Edit this file and set VIRTUAL_HOST as my_domain.com, LETSENCRYPT_HOST as my_domain.com, and your email on LETSENCRYPT_EMAIL

Edit deploy/docker/local_settings.py and set https://my_domain.com as FRONTEND_HOST

Now run docker-compose -f docker-compose-letsencrypt.yaml up, when installation finishes you will be able to access https://my_domain.com using a valid Letsencrypt certificate!

Advanced Deployment, accessed as http://localhost:8000

Here we can run 1 mediacms_web instance, with the FRONTEND_HOST in deploy/docker/local_settings.py configured as http://localhost:8000. This is bootstrapped by a single migrations instance and supported by a single celery_beat instance and 1 or more celery_worker instances. Redis and postgres containers are also used for persistence. Clients can access the service on http://localhost:8000, on the docker host machine. This is similar to this deployment, with a port defined in FRONTEND_HOST.

Advanced Deployment, with reverse proxy, accessed as http://mediacms.io

Here we can use jwilder/nginx-proxy to reverse proxy to 1 or more instances of mediacms_web supported by other services as mentioned in the previous deployment. The FRONTEND_HOST in deploy/docker/local_settings.py is configured as http://mediacms.io, nginx-proxy has port 80 exposed. Clients can access the service on http://mediacms.io (Assuming DNS or the hosts file is setup correctly to point to the IP of the nginx-proxy instance). This is similar to this deployment.

Advanced Deployment, with reverse proxy, accessed as https://localhost

The reverse proxy (jwilder/nginx-proxy) can be configured to provide SSL termination using self-signed certificates, letsencrypt or CA signed certificates (see: https://hub.docker.com/r/jwilder/nginx-proxy or LetsEncrypt Example ). In this case the FRONTEND_HOST should be set to https://mediacms.io. This is similar to this deployment.

A Scaleable Deployment Architecture (Docker, Swarm, Kubernetes)

The architecture below generalises all the deployment scenarios above, and provides a conceptual design for other deployments based on kubernetes and docker swarm. It allows for horizontal scaleability through the use of multiple mediacms_web instances and celery_workers. For large deployments, managed postgres, redis and storage may be adopted.

5. Configuration

Several options are available on cms/settings.py, most of the things that are allowed or should be disallowed are described there.

It is advisable to override any of them by adding it to local_settings.py .

In case of a the single server installation, add to cms/local_settings.py .

In case of a docker compose installation, add to deploy/docker/local_settings.py . This will automatically overwrite cms/local_settings.py .

Any change needs restart of MediaCMS in order to take effect.

Single server installation: edit cms/local_settings.py, make a change and restart MediaCMS

#systemctl restart mediacms

Docker Compose installation: edit deploy/docker/local_settings.py, make a change and restart MediaCMS containers

#docker-compose restart web celery_worker celery_beat

5.1 Change portal logo

Set a new svg file for the white theme (static/images/logo_dark.svg) or the dark theme (static/images/logo_light.svg)

5.2 Set global portal title

set PORTAL_NAME, eg

PORTAL_NAME = 'my awesome portal'

5.3 Control who can add media

By default CAN_ADD_MEDIA = "all" means that all registered users can add media. Other valid options are:

email_verified, a user not only has to register an account but also verify the email (by clicking the link sent upon registration). Apparently email configuration need to work, otherise users won't receive emails.
advancedUser, only users that are marked as advanced users can add media. Admins or MediaCMS managers can make users advanced users by editing their profile and selecting advancedUser.

5.4 What is the portal workflow

The PORTAL_WORKFLOW variable specifies what happens to newly uploaded media, whether they appear on listings (as the index page, or search)

public is the default option and means that a media can appear on listings. If media type is video, it will appear once at least a task that produces an encoded version of the file has finished succesfully. For other type of files, as image/audio they appear instantly
private means that newly uploaded content is private - only users can see it or MediaCMS editors, managers and admins. Those can also set the status to public or unlisted
unlisted means that items are unlisted. However if a user visits the url of an unlisted media, it will be shown (as opposed to private)

to show button:

LOGIN_ALLOWED = True

to hide button:

LOGIN_ALLOWED = False

5.6 Show or hide the Register button

to show button:

REGISTER_ALLOWED = True

to hide button:

REGISTER_ALLOWED = False

5.7 Show or hide the upload media button

To show:

UPLOAD_MEDIA_ALLOWED = True

To hide:

UPLOAD_MEDIA_ALLOWED = False

5.8 Show or hide the actions buttons (like/dislike/report)

Make changes (True/False) to any of the following:

- CAN_LIKE_MEDIA = True  # whether the like media appears
- CAN_DISLIKE_MEDIA = True  # whether the dislike media appears
- CAN_REPORT_MEDIA = True  # whether the report media appears
- CAN_SHARE_MEDIA = True  # whether the share media appears

5.9 Show or hide the download option on a media

Edit templates/config/installation/features.html and set

download: false

5.10 Automatically hide media upon being reported

set a low number for variable REPORTED_TIMES_THRESHOLD eg

REPORTED_TIMES_THRESHOLD = 2

once the limit is reached, media goes to private state and an email is sent to admins

5.11 Set a custom message on the media upload page

this message will appear below the media drag and drop form

PRE_UPLOAD_MEDIA_MESSAGE = 'custom message'

5.12 Set email settings

Set correct settings per provider

DEFAULT_FROM_EMAIL = 'info@mediacms.io'
EMAIL_HOST_PASSWORD = 'xyz'
EMAIL_HOST_USER = 'info@mediacms.io'
EMAIL_USE_TLS = True
SERVER_EMAIL = DEFAULT_FROM_EMAIL
EMAIL_HOST = 'mediacms.io'
EMAIL_PORT = 587
ADMIN_EMAIL_LIST = ['info@mediacms.io']

5.13 Disallow user registrations from specific domains

set domains that are not valid for registration via this variable:

RESTRICTED_DOMAINS_FOR_USER_REGISTRATION = [
    'xxx.com', 'emaildomainwhatever.com']

5.14 Require a review by MediaCMS editors/managers/admins

set value

MEDIA_IS_REVIEWED = False

any uploaded media now needs to be reviewed before it can appear to the listings. MediaCMS editors/managers/admins can visit the media page and edit it, where they can see the option to mark media as reviewed. By default this is set to True, so all media don't require to be reviewed

5.15 Specify maximum number of media for a playlist

set a different threshold on variable MAX_MEDIA_PER_PLAYLIST

MAX_MEDIA_PER_PLAYLIST = 14

5.16 Specify maximum size of a media that can be uploaded

change UPLOAD_MAX_SIZE.

default is 4GB

UPLOAD_MAX_SIZE = 800 * 1024 * 1000 * 5

5.17 Specify maximum size of comments

change MAX_CHARS_FOR_COMMENT

default:

MAX_CHARS_FOR_COMMENT = 10000

5.18 How many files to upload in parallel

set a different threshold for UPLOAD_MAX_FILES_NUMBER default:

UPLOAD_MAX_FILES_NUMBER = 100

5.18 force users confirm their email upon registrations

default option for email confirmation is optional. Set this to mandatory in order to force users confirm their email before they can login

ACCOUNT_EMAIL_VERIFICATION = 'optional'

after this number is reached

ACCOUNT_LOGIN_ATTEMPTS_LIMIT = 20

sets a timeout (in seconds)

ACCOUNT_LOGIN_ATTEMPTS_TIMEOUT = 5

5.21 Disallow user registration

set the following variable to False

USERS_CAN_SELF_REGISTER = True

5.22 Configure notifications

Global notifications that are implemented are controlled by the following options:

USERS_NOTIFICATIONS = {
    'MEDIA_ADDED': True,
}

If you want to disable notification for new media, set to False

Admins also receive notifications on different events, set any of the following to False to disable

ADMINS_NOTIFICATIONS = {
    'NEW_USER': True,
    'MEDIA_ADDED': True,
    'MEDIA_REPORTED': True,
}

NEW_USER: a new user is added
MEDIA_ADDED: a media is added
MEDIA_REPORTED: the report for a media was hit

5.23 Configure only member access to media

Make the portal workflow public, but at the same time set GLOBAL_LOGIN_REQUIRED = True so that only logged in users can see content.
You can either set REGISTER_ALLOWED = False if you want to add members yourself or checkout options on "django-allauth settings" that affects registration in cms/settings.py. Eg set the portal invite only, or set email confirmation as mandatory, so that you control who registers.

12. Video transcoding

Add / remove resolutions and profiles by modifying the database table of Encode profiles through https://your_installation/admin/files/encodeprofile/

For example, the Active state of any profile can be toggled to enable or disable it.

13. How To Add A Static Page To The Sidebar

1. Create your html page in templates/cms/

e.g. duplicate and rename about.html

sudo cp templates/cms/about.html templates/cms/volunteer.html

2. Create your css file in static/css/

touch static/css/volunteer.css

3. In your html file, update block headermeta to reflect your new page

{% block headermeta %}
<meta property="og:title" content="Volunteer - {{PORTAL_NAME}}">
<meta property="og:type" content="website">
<meta property="og:description" content="">
<meta name="twitter:card" content="summary">
<script type="application/ld+json">
{
	"@context": "https://schema.org",
	"@type": "BreadcrumbList",
	"itemListElement": [{
		"@type": "ListItem",
		"position": 1,
        "name": "{{PORTAL_NAME}}",
        "item": {
			"@type": "WebPage",
	        "@id": "{{FRONTEND_HOST}}"
	    }
    },
    {
		"@type": "ListItem",
		"position": 2,
        "name": "Volunteer",
        "item": {
			"@type": "VolunteerPage",
	        "@id": "{{FRONTEND_HOST}}/volunteer"
	    }
    }]
}
</script>
<link href="{% static "css/volunteer.css" %}" rel="stylesheet"/>
{% endblock headermeta %}

4. In your html file, update block innercontent to reflect your actual content

Write whatever you like.

5. In your css file, write matching styles for you html file.

Write whatever you like.

6. Add your view to files/views.py

def volunteer(request):
    """Volunteer view"""
    context = {}
    return render(request, "cms/volunteer.html", context)

7. Add your url pattern to files/urls.py

urlpatterns = [
    url(r"^$", views.index),
    url(r"^about", views.about, name="about"),
    url(r"^volunteer", views.volunteer, name="volunteer"),

8. Add your page to the left sidebar

To add a link to your page as a menu item in the left sidebar, add the following code after the last line in _commons.js

/* Checks that a given selector has loaded. */
const checkElement = async selector => {
    while ( document.querySelector(selector) === null) {
      await new Promise( resolve =>  requestAnimationFrame(resolve) )
    }
    return document.querySelector(selector);
  };

/* Checks that sidebar nav menu has loaded, then adds menu item. */
checkElement('.nav-menu')
.then((element) => {
     (function(){
        var a = document.createElement('a');
        a.href = "/volunteer";
        a.title = "Volunteer";

        var s = document.createElement('span');
        s.className = "menu-item-icon";

        var icon = document.createElement('i');
        icon.className = "material-icons";
        icon.setAttribute("data-icon", "people");

        s.appendChild(icon);
        a.appendChild(s);

        var linkText = document.createTextNode("Volunteer");
        var t = document.createElement('span');

        t.appendChild(linkText);
        a.appendChild(t);

        var listItem = document.createElement('li');
        listItem.className = "link-item";
        listItem.appendChild(a);

        //if signed out use 3rd nav-menu
        var elem = document.querySelector(".nav-menu:nth-child(3) nav ul");
        var loc = elem.innerText;
        if (loc.includes("About")){
          elem.insertBefore(listItem, elem.children[2]);
        } else { //if signed in use 4th nav-menu
          elem = document.querySelector(".nav-menu:nth-child(4) nav ul");
          elem.insertBefore(listItem, elem.children[2]);
        }
    })();
});

9. Restart the mediacms web server

On docker:

sudo docker stop mediacms_web_1 && sudo docker start mediacms_web_1

Otherwise

sudo systemctl restart mediacms

14. Add Google Analytics

Instructions contributed by @alberto98fx

Create a file:

touch $DIR/mediacms/templates/tracking.html

Add the Gtag/Analytics script
Inside $DIR/mediacms/templates/root.html you'll see a file like this one:

<head>
    {% block head %}

        <title>{% block headtitle %}{{PORTAL_NAME}}{% endblock headtitle %}</title>

        {% include "common/head-meta.html" %}

        {% block headermeta %}

        <meta property="og:title" content="{{PORTAL_NAME}}">
        <meta property="og:type" content="website">

        {%endblock headermeta %}

        {% block externallinks %}{% endblock externallinks %}

        {% include "common/head-links.html" %}

        {% block topimports %}{%endblock topimports %}

        {% include "config/index.html" %}

    {% endblock head %}

</head>

Add {% include "tracking.html" %} at the end inside the section <head>
If you are using Docker and didn't mount the entire dir you need to bind a new volume:


    web:
    image: mediacms/mediacms:latest
    restart: unless-stopped
    ports:
      - "80:80"
    deploy:
      replicas: 1
    volumes:
      - ./templates/root.html:/home/mediacms.io/mediacms/templates/root.html
      - ./templates/tracking.html://home/mediacms.io/mediacms/templates/tracking.html

15. Debugging email issues

On the Configuration section of this guide we've see how to edit the email settings. In case we are yet unable to receive email from MediaCMS, the following may help us debug the issue - in most cases it is an issue of setting the correct username, password or TLS option

Enter the Django shell, example if you're using the Single Server installation:

source  /home/mediacms.io/bin/activate
python manage.py shell

and inside the shell

from django.core.mail import EmailMessage
from django.conf import settings

settings.EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

email = EmailMessage(
    'title',
    'msg',
    settings.DEFAULT_FROM_EMAIL,
    ['recipient@email.com'],
)
email.send(fail_silently=False)

You have the chance to either receive the email (in this case it will be sent to recipient@email.com) otherwise you will see the error. For example, while specifying wrong password for my Gmail account I get

SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8  https://support.google.com/mail/?p=BadCredentials d4sm12687785wrc.34 - gsmtp')

16. Frequently Asked Questions

Video is playing but preview thumbnails are not showing for large video files

Chances are that the sprites file was not created correctly. The output of files.tasks.produce_sprite_from_video() function in this case is something like this

convert-im6.q16: width or height exceeds limit `/tmp/img001.jpg' @ error/cache.c/OpenPixelCache/3912.

Solution: edit file /etc/ImageMagick-6/policy.xml and set bigger values for the lines that contain width and height. For example

  <policy domain="resource" name="height" value="16000KP"/>
  <policy domain="resource" name="width" value="16000KP"/>

Newly added video files now will be able to produce the sprites file needed for thumbnail previews. To re-run that task on existing videos, enter the Django shell

root@8433f923ccf5:/home/mediacms.io/mediacms# source  /home/mediacms.io/bin/activate
root@8433f923ccf5:/home/mediacms.io/mediacms# python manage.py shell
Python 3.8.14 (default, Sep 13 2022, 02:23:58)

and run

In [1]: from files.models import Media
In [2]: from files.tasks import produce_sprite_from_video

In [3]: for media in Media.objects.filter(media_type='video', sprites=''):
   ...:     produce_sprite_from_video(media.friendly_token)

this will re-create the sprites for videos that the task failed.

On file templates/components/header.html you can find a simple cookie consent code. It is commented, so you have to remove the {% comment %} and {% endcomment %} lines in order to enable it. Or you can replace that part with your own code that handles cookie consent banners.

18. Disable encoding and show only original file

When videos are uploaded, they are getting encoded to multiple resolutions, a procedure called transcoding. Sometimes this is not needed and you only need to show the original file, eg when MediaCMS is running on a low capabilities server. To achieve this, edit settings.py and set

DO_NOT_TRANSCODE_VIDEO = True

This will disable the transcoding process and only the original file will be shown. Note that this will also disable the sprites file creation, so you will not have the preview thumbnails on the video player.
