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).
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.
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.
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.
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](https://docs.docker.com/get-docker/), and [Docker Compose](https://docs.docker.com/compose/install/).
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](/docs/admins_docs.md#4-docker-deployment-options) section for different docker-compose setups to use.
Run
```bash
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
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
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
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](../docker-compose.yaml), 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](../docker-compose-http-proxy.yaml).
### 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](https://www.singularaspect.com/use-nginx-proxy-and-letsencrypt-companion-to-host-multiple-websites/) ). In this case the FRONTEND_HOST should be set to https://mediacms.io. This is similar to [this deployment](../docker-compose-http-proxy.yaml).
### 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.
- **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)
### 5.5 Show or hide the Sign in button
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
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`
eg
```
MAX_MEDIA_PER_PLAYLIST = 14
```
### 5.16 Specify maximum size of a media that can be uploaded
- 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.
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.
On the [Configuration](https://github.com/mediacms-io/mediacms/blob/main/docs/admins_docs.md#5-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:
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')
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
this will re-create the sprites for videos that the task failed.
## 17. Cookie consent code
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.
