# Dependencies
|
|
|
|
## Debian / Ubuntu and derivatives
|
|
|
|
This documentation is appropriate for Debian 10 (Buster) and Ubuntu 18.04 LTS.
|
|
|
|
### Security
|
|
|
|
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:
|
|
|
|
```bash
|
|
sudo apt update
|
|
sudo apt dist-upgrade
|
|
```
|
|
|
|
### Basic tools
|
|
We begin by making sure some basic tools are installed:
|
|
|
|
```bash
|
|
sudo apt install build-essential curl unzip vim openssl git
|
|
```
|
|
|
|
### Web server
|
|
We only officially support nginx.
|
|
|
|
```bash
|
|
sudo apt install nginx
|
|
```
|
|
|
|
### HTTPS Certificates
|
|
Then we need to install [certbot](https://certbot.eff.org/), a tool to ask for free Let's Encrypt HTTPS certificates.
|
|
|
|
```bash
|
|
sudo apt install certbot
|
|
```
|
|
|
|
You can use certbot with web server plugins or manually. See [Certbot's documentation](https://certbot.eff.org/instructions).
|
|
|
|
|
|
### NodeJS
|
|
We install the latest NodeJS version by adding NodeSource repos and installing NodeJS:
|
|
|
|
Head over to [this page](https://github.com/nodesource/distributions/blob/master/README.md#table-of-contents) and follow the instructions for `Node.js v12.x`.
|
|
|
|
!!! info
|
|
Unless stated otherwise, Mobilizon always supports only the latest LTS version of NodeJS.
|
|
|
|
!!! tip
|
|
NodeSource repos only gives updates for a specific version of NodeJS (it doesn't upgrade itself to a new major version). When a new major version of NodeJS is released, you need to remove the old repo and add the new one.
|
|
|
|
### Yarn
|
|
Mobilizon uses [Yarn](https://yarnpkg.com/) to manage NodeJS packages, so we need to install it as well.
|
|
|
|
Follow the instructions on [this page](https://yarnpkg.com/en/docs/install#debian-stable) to add Yarn's repository and install it.
|
|
|
|
!!! info
|
|
It is also possible to install `yarn` directly with `npm`:
|
|
```bash
|
|
npm install -g yarn
|
|
```.
|
|
You need to make sure npm's binary packages folder in your `$PATH` afterwards to use `yarn`.
|
|
|
|
### Erlang and Elixir
|
|
|
|
The packages from Debian or Ubuntu are badly packaged and often out of date, so we need to add one final source repository.
|
|
|
|
Follow the instructions for Ubuntu/Debian on [this page](https://elixir-lang.org/install.html#unix-and-unix-like) to add Erlang Solutions repo and install Erlang and Elixir.
|
|
|
|
!!! tip
|
|
The Erlang package also wants to install an add-on for Emacs for some reason (but it doesn't install Emacs). If you see a warning, nothing to worry about.
|
|
|
|
### PostgreSQL and PostGIS
|
|
|
|
Mobilizon uses the [PostgreSQL](https://www.postgresql.org) database, and the PostgreSQL [Postgis](https://postgis.net) extension to store geographical data into PostgreSQL.
|
|
|
|
```bash
|
|
sudo apt install postgresql postgresql-contrib postgis
|
|
```
|
|
|
|
After that we can enable and start the PostgreSQL service.
|
|
```
|
|
sudo systemctl --now enable postgresql
|
|
```
|
|
|
|
### Misc
|
|
|
|
We need the following tools to handle and optimize pictures that are uploaded on Mobilizon.
|
|
|
|
```bash
|
|
sudo apt install imagemagick
|
|
```
|
|
|
|
The following packages are optional, Mobilizon can run without them.
|
|
|
|
```bash
|
|
sudo apt install webp gifsicle jpegoptim optipng pngquant
|
|
```
|
|
|
|
Once finished, let's [head back to the install guide](index.md).
|
|
|
|
## Arch Linux
|
|
|
|
Run the following command to install all at once:
|
|
```bash
|
|
sudo pacman -S nodejs postgresql openssl git wget unzip base-devel yarn nginx elixir postgis imagemagick
|
|
```
|
|
|
|
Now that dependencies are installed, before running Mobilizon you should start PostgreSQL:
|
|
```
|
|
sudo systemctl --now enable postgresql
|
|
```
|
|
|
|
Once finished, let's [head back to the install guide](index.md).
