# Pleroma
## About Pleroma
Pleroma is an OStatus-compatible social networking server written in Elixir, compatible with GNU Social and Mastodon. It is high-performance and can run on small devices like a Raspberry Pi.
No release has been made yet, but several servers have been online for months already. If you want to run your own server, feel free to contact us at @lain@pleroma.soykaf.com or in our dev chat at https://matrix.heldscal.la/#/room/#pleromafe:matrix.heldscal.la.
## Installation
### Dependencies
* Postgresql version 9.6 or newer
* Elixir version 1.4 or newer
* NodeJS LTS
* Build-essential tools
#### Installing dependencies on Debian system

Elixir will also require `make` and probably other related software for building dependencies - in case you don't have them, get them via `apt install build-essential`
NodeJS is available as `nodejs` package on Debian. `apt install nodejs`. Debian stable has 4.8.x version. If that does not work, use nodesource's repo https://github.com/nodesource/distributions#deb - version 5.x confirmed to work.
### Preparation
* You probably want application to run as separte user - so create a new one: `adduser pleroma`, you can login as it via `su pleroma`

### Database setup
* You'll need to allow password-based authorisation for `postgres` superuser
* Changing default password for superuser is probably a good idea:
* Open psql shell as postgres user - while being root run `su postgres -c psql`
* There, enter following:
```sql
ALTER USER postgres with encrypted password '<PASSWORD>';
```
where `<PASSWORD>` is any string, no need to manually encrypt it - postgres will encrypt it automatically for you.
* Replace password in file `config/dev.exs` with password you supplied in previous step (look for line like `password: "postgres"`)
* Edit `/etc/postgresql/9.6/main/pg_hba.conf` (Assuming you have the 9.6 version) and change the line:
```
local all postgres peer
```
to
```
local all postgres md5
```
don't forget to revert it in the later step so you won't have to enter password when accessing psql console.
* Create and update your database with `mix ecto.create && mix ecto.migrate`. If it gives errors, try running again, this is a known issue.
* Undo changes you made in `/etc/postgresql/9.6/main/pg_hba.conf` (replace `md5` with `peer`)
* You most likely don't want having some application accessing database as a superuser, so you should create separate user for Pleroma. Right now it must be done manually (issue #27).
* Create a database user and database for pleroma
* Open psql shell as postgres user: (as root) `su postgres -c psql`
* Create a new PostgreSQL user:

In file `config/dev.exs`, add these lines at the end of the file:
```elixir
config :pleroma, Pleroma.Web.Endpoint,
url: [host: "example.tld", scheme: "https", port: 443]
url: [host: "example.tld", scheme: "https", port: 443]
```
replacing `example.tld` with your (sub)domain
* The common and convenient way for adding HTTPS is by using Nginx as a reverse proxy. You can look at example Nginx configuration in `installation/pleroma.nginx`. If you need TLS/SSL certificates for HTTPS, you can look get some for free with letsencrypt: https://letsencrypt.org/
On Debian you can use `certbot` package and command to manage letsencrypt certificates.

Run `mix phx.server` in repository's root, it will output log into stdout/stderr
