## Installation
This guide will assume that you have administrative rights, either as root or a user with [sudo permissions](https://wiki.archlinux.org/index.php/Sudo). If you want to run this guide with root, ignore the `sudo` at the beginning of the lines, unless it calls a user like `sudo -Hu pleroma`; in this case, use `su <username> -s $SHELL -c 'command'` instead.
* `git`
* `base-devel`
* `cmake`
-* `ffmpeg`
-* `ImageMagick`
+* `file`
#### Optional packages used in this guide
* `nginx` (preferred, example configs for other reverse proxies can be found in the repo)
* `certbot` (or any other ACME client for Let’s Encrypt certificates)
+* `ImageMagick`
+* `ffmpeg`
+* `exiftool`
### Prepare the system
* Install some of the above mentioned programs:
```shell
-sudo pacman -S git base-devel elixir cmake ffmpeg imagemagick
+sudo pacman -S git base-devel elixir cmake file
```
### Install PostgreSQL
sudo systemctl enable --now postgresql.service
```
+### Install media / graphics packages (optional, see [`docs/installation/optional/media_graphics_packages.md`](../installation/optional/media_graphics_packages.md))
+
+```shell
+sudo pacman -S ffmpeg imagemagick perl-image-exiftool
+```
+
### Install PleromaBE
* Add a new system user for the Pleroma service:
sudo -Hu pleroma mix deps.get
```
-* Generate the configuration: `sudo -Hu pleroma mix pleroma.instance gen`
+* Generate the configuration: `sudo -Hu pleroma MIX_ENV=prod mix pleroma.instance gen`
* Answer with `yes` if it asks you to install `rebar3`.
* This may take some time, because parts of pleroma get compiled first.
* After that it will ask you a few questions about your instance and generates a configuration file in `config/generated_config.exs`.
* Check the configuration and if all looks right, rename it, so Pleroma will load it (`prod.secret.exs` for productive instance, `dev.secret.exs` for development instances):
```shell
-mv config/{generated_config.exs,prod.secret.exs}
+sudo -Hu pleroma mv config/{generated_config.exs,prod.secret.exs}
```
* The previous command creates also the file `config/setup_db.psql`, with which you can create the database:
