# Pleroma
## Installation
### Dependencies
* Postgresql version 9.5 or newer
* Elixir version 1.4 or newer
* NodeJS LTS
* Build-essential tools
#### Installing dependencies on Debian system
PostgreSQL 9.6 should be available on debian stable (Jessie) from "main" area. Install it using apt: `apt install postgresql-9.6`. Make sure that older versions are not installed, debian allows multiple versions to coexist but still runs only one version.
You must install elixir 1.4+ from elixir-lang.org, because Debian repos only have 1.3.x version. You will need to add apt repo to sources.list(.d) and import GPG key. Follow instructions here: https://elixir-lang.org/install.html#unix-and-unix-like (See "Ubuntu or Debian 7"). This should be valid until Debian updates elixir in their repositories. Package you want is named `elixir`, so install it using `apt install elixir`
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`
* Clone the git repository into new user's dir (clone as the pleroma user to avoid permissions errors)
* Again, as new user, install dependencies with `mix deps.get` if it asks you to install "hex" - agree to that.
### Database preparation
* 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: `ALTER USER postgres with encrypted password '<PASSWORD>';` - where <PASSWORD> is just 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 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 superuser, so you need to create separate user for that. Right now it must be done manually (issue #27).
* Open psql shell as postgres user: (as root) `su postgres -c psql`
* Create a new PostgreSQL user:
```sql
\c pleroma_dev
CREATE user pleroma;
ALTER user pleroma with encrypted password '<your password>';
GRANT ALL ON ALL tables IN SCHEMA public TO pleroma;
GRANT ALL ON ALL sequences IN SCHEMA public TO pleroma;
```
* Again, change password in `config/dev.exs`, and change user to `"pleroma"` (line like `username: "postgres"`)
### Some additional configuration
* You will need to let pleroma instance to know what hostname/url it's running on.
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]
```
replacing `example.tld` with your (sub)domain
* The common and convenient way for adding HTTPS is by using nginx as 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.
* (not tested with reboots yet!) You'll also want to set up Pleroma to be run as a systemd service. Example .service can be found in `installation/pleroma.service` you can put it in `/etc/systemd/system/`.
Start pleroma by running `service pleroma start`
Logs can be watched by using `journalctl -fu pleroma.service`
* Without systemd you can start Pleroma by starting Phoenix endpoint with `mix phx.server`
In any case, it should be available on 4000 port on localhost and proxied to 443 port by nginx.
