# Configuration
|
||||
|
||||
Basic Mobilizon configuration can be handled through the Admin panel in the UI.
|
||||
|
||||
Core mobilizon configuration must be managed into the `config/prod.secret.exs` file.
|
||||
After performing changes to this file, you have to recompile the mobilizon app with:
|
||||
```bash
|
||||
MIX_ENV=prod mix compile
|
||||
```
|
||||
and then restart the Mobilizon service:
|
||||
```
|
||||
systemctl restart mobilizon
|
||||
```

We advise to make sure your webserver is secure enough.
|
||||
For instance you can require authentication through SSH keys and not passwords, install Fail2Ban to block repeated login attempts and block unused ports by installing and configuring a firewall.

### Upgrade system

Just to be sure your system is up-to-date before doing anything else:

Then adapt the nginx configuration `/etc/nginx/sites-available/mobilizon.conf` by uncommenting certificate paths and removing obsolete blocks.

sudo -i -u mobilizon

!!! 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](./configure) as well.

## Optional tasks

||||
### Geolocation databases
|
||||
|
||||
Mobilizon can use geolocation from MMDB format data from sources like [MaxMind GeoIP](https://dev.maxmind.com/geoip/geoip2/geolite2/) databases or [db-ip.com](https://db-ip.com/db/download/ip-to-city-lite) 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`.

You will need to download the City database and put it into `priv/data/GeoLite2-City.mmdb`. Finish by restarting the `mobilizon` service.
