Install
!!! info "Docker"
Docker production installation is not yet supported. See [issue #352](https://framagit.org/framasoft/mobilizon/issues/352).
Pre-requisites
- A Linux machine with root access
- A domain name (or subdomain) for the Mobilizon server, e.g.
your-mobilizon-domain.com - An SMTP server to deliver emails
Dependencies
Mobilizon requires Elixir, NodeJS and PostgreSQL among other things.
Installing dependencies depends on the system you're using. Follow the steps of the dependencies guide.
Setup
We're going to use a dedicated mobilizon user with /home/mobilizon home:
sudo adduser --disabled-login mobilizon
!!! tip
On FreeBSD
``` bash
sudo pw useradd -n mobilizon -d /home/mobilizon -s /usr/local/bin/bash -m
sudo passwd mobilizon
```
Then let's connect as this user:
sudo -i -u mobilizon
Let's start by cloning the repository in a directory named live:
git clone https://framagit.org/framasoft/mobilizon live && cd live
Installing dependencies
Install Elixir dependencies
mix deps.get
!!! note
When asked for Shall I install Hex? or Shall I install rebar3?, hit the enter key to confirm.
Then compile these dependencies and Mobilizon (this can take a few minutes, and can output all kinds of warnings, such as depreciation issues)
MIX_ENV=prod mix compile
Go into the js/ directory
cd js
and install the Javascript dependencies
yarn install
Finally, we can build the front-end (this can take a few seconds).
!!! warning
Building front-end can consume up to 512MB of RAM by default. If it's too much or not sufficient for your setup, you can adjust the maximum memory used by prefixing the command with the following option:
NODE_OPTIONS=--max_old_space_size=4096
yarn run build
Let's go back to the main directory
cd ../
Configuration
Mobilizon provides a command line tool to generate configuration
MIX_ENV=prod mix mobilizon.instance gen
This will ask you questions about your setup and your instance to generate a prod.secret.exs file in the config/ folder, and a setup_db.psql file to setup the database.
Database setup
The setup_db.psql file contains SQL instructions to create a PostgreSQL user and database with the chosen credentials and add the required extensions to the Mobilizon database.
Exit running as the mobilizon user (as it shouldn't have root/sudo rights) and execute in the /home/mobilizon/live directory:
sudo -u postgres psql -f setup_db.psql
It should output something like:
CREATE ROLE
CREATE DATABASE
You are now connected to database "mobilizon_prod" as user "postgres".
CREATE EXTENSION
CREATE EXTENSION
CREATE EXTENSION
Let's get back to our mobilizon user:
sudo -i -u mobilizon
cd live
!!! warning
When it's done, don't forget to remove the `setup_db.psql` file.
Database Migration
Run database migrations:
MIX_ENV=prod mix ecto.migrate
!!! note
Note the `MIX_ENV=prod` environment variable prefix in front of the command. You will have to use it for each `mix` command from now on.
You will have to do this again after most updates.
!!! tip If some migrations fail, it probably means you're not using a recent enough version of PostgreSQL, or that you haven't installed the required extensions.
Services
We can quit using the mobilizon user again.
Systemd
Copy the support/systemd/mobilizon.service to /etc/systemd/system.
sudo cp support/systemd/mobilizon.service /etc/systemd/system/
Reload Systemd to detect your new file
sudo systemctl daemon-reload
And enable the service
systemctl enable --now mobilizon.service
It will run Mobilizon and enable startup on boot. You can follow the logs with
sudo journalctl -fu mobilizon.service
You should see something like this:
Running Mobilizon.Web.Endpoint with cowboy 2.8.0 at :::4000 (http)
Access Mobilizon.Web.Endpoint at https://your-mobilizon-domain.com
The Mobilizon server runs on port 4000 on the local interface only, so you need to add a reverse-proxy.
Reverse proxy
Nginx
Copy the file from support/nginx/mobilizon.conf to /etc/nginx/sites-available.
sudo cp support/nginx/mobilizon.conf /etc/nginx/sites-available
Then symlink the file into the /etc/nginx/sites-enabled directory.
sudo ln -s /etc/nginx/sites-available/mobilizon.conf /etc/nginx/sites-enabled/
Edit the file /etc/nginx/sites-available and adapt it to your own configuration.
Test the configuration with sudo nginx -t and reload nginx with sudo systemctl reload nginx.
Let's Encrypt
The nginx configuration template handles the HTTP-01 challenge with the webroot plugin:
sudo mkdir /var/www/certbot
Run certbot with (don't forget to adapt the command)
sudo certbot certonly --rsa-key-size 4096 --webroot -w /var/www/certbot/ --email your@email.com --agree-tos --text --renew-hook "/usr/sbin/nginx -s reload" -d your-mobilizon-domain.com
Then adapt the nginx configuration /etc/nginx/sites-available/mobilizon.conf by uncommenting certificate paths and removing obsolete blocks.
Finish by testing the configuration with sudo nginx -t and reloading nginx with systemctl reload nginx.
You should now be able to load https://your-mobilizon-domain.com inside your browser.
Creating your first user
Login back as the mobilizon system user:
sudo -i -u mobilizon
cd live
Create a new user:
MIX_ENV=prod mix mobilizon.users.new "your@email.com" --admin --password "Y0urP4ssw0rd"
!!! danger Don't forget to prefix the command with an empty space so that the chosen password isn't kept in your shell history.
!!! tip
You can ignore the --password option and Mobilizon will generate one for you.
See the [full documentation](./CLI tasks/manage_users.md#create-a-new-user) for this command.
You may now login with your credentials and discover Mobilizon. Feel free to explore configuration documentation as well.
Optional tasks
Geolocation databases
Mobilizon can use geolocation from MMDB format data from sources like MaxMind GeoIP databases or db-ip.com databases. This allows showing events happening near the user's location.
You will need to download the City database and put it into priv/data/GeoLite2-City.mmdb. Finish by restarting the mobilizon service.
Mobilizon will only show a warning at startup if the database is missing, but it isn't required.
