# Pleroma
+## About Pleroma
+
+Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support the same federation standards (OStatus and ActivityPub). What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement either OStatus or ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.
+
+Pleroma is written in Elixir, high-performance and can run on small devices like a Raspberry Pi.
+
+For clients it supports both the [GNU Social API with Qvitter extensions](https://twitter-api.readthedocs.io/en/latest/index.html) and the [Mastodon client API](https://github.com/tootsuite/documentation/blob/master/Using-the-API/API.md).
+
+Client applications that are known to work well:
+
+* Twidere
+* Tusky
+* Pawoo (Android + iOS)
+* Subway Tooter
+* Amaroq (iOS)
+* Tootdon (Android + iOS)
+* Tootle (iOS)
+* Whalebird (Windows + Mac + Linux)
+
+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 #pleroma on freenode or via matrix at https://matrix.heldscal.la/#/room/#freenode_#pleroma:matrix.org.

## Installation
+### Docker
+
+While we don't provide docker files, other people have written very good ones. Take a look at https://github.com/Angristan/dockerfiles/tree/master/pleroma or https://github.com/sn0w/pleroma-docker.
+
### Dependencies
-* Postgresql version 9.5 or newer
-* Elixir version 1.4 or newer
-* NodeJS LTS
+* Postgresql version 9.6 or newer
+* Elixir version 1.5 or newer. If your distribution only has an old version available, check [Elixir's install page](https://elixir-lang.org/install.html) or use a tool like [asdf](https://github.com/asdf-vm/asdf).
+* Build-essential tools
+
+### Configuration
+
+ * Run `mix deps.get` to install elixir dependencies.
-#### 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 `postgresql-9.5` or older is not installed, for some strange reason debian allows multiple versions to coexist, what effect it has - i don't know.
+ * Run `mix generate_config`. This will ask you a few questions about your instance and generate a configuration file in `config/generated_config.exs`. Check that and copy it to either `config/dev.secret.exs` or `config/prod.secret.exs`. It will also create a `config/setup_db.psql`; you may want to double-check this file in case you wanted a different username, or database name than the default. Then you need to run the script as PostgreSQL superuser (i.e. `sudo su postgres -c "psql -f config/setup_db.psql"`). It will create a pleroma db user, database and will setup needed extensions that need to be set up. Postgresql super-user privileges are only needed for this step.
-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`
+ * For these next steps, the default will be to run pleroma using the dev configuration file, `config/dev.secret.exs`. To run them using the prod config file, prefix each command at the shell with `MIX_ENV=prod`. For example: `MIX_ENV=prod mix phx.server`. Documentation for the config can be found at [``config/config.md``](config/config.md)
-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.
+ * Run `mix ecto.migrate` to run the database migrations. You will have to do this again after certain updates.
-### Preparation
+ * You can check if your instance is configured correctly by running it with `mix phx.server` and checking the instance info endpoint at `/api/v1/instance`. If it shows your uri, name and email correctly, you are configured correctly. If it shows something like `localhost:4000`, your configuration is probably wrong, unless you are running a local development setup.
- * You probably want application to run as separte user - so create a new one: `adduser pleroma`
- * Clone the git repository into new user's dir (clone as the 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.
+ * 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/
+ The simplest way to obtain and install a certificate is to use [Certbot.](https://certbot.eff.org) Depending on your specific setup, certbot may be able to get a certificate and configure your web server automatically.
-### Database preparation
+## Running
- * 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: (as root) `su postgres -c psql`
- * There, enter following: `ALTER USER postgres with encrypted password '<YOUR SECURE PASSWORD>';`
- * 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
- ```
- * Create and migrate your database with `mix ecto.create && mix ecto.migrate`. If it gives errors, try running again, it should be ok.
- * You most likely don't want having some application accessing database as superuser, so we need to create separate user for that. For now it's done manually (issue #27).
- * Revert `/etc/postgresql/9.6/main/pg_hba.conf` to previous state (replace `md5` with `peer`)
- * 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 too to `"pleroma"` (like like `username: "postgres"`)
+* By default, it listens on port 4000 (TCP), so you can access it on http://localhost:4000/ (if you are on the same machine). In case of an error it will restart automatically.
-### Some additional configuration
+### Frontends
+Pleroma comes with two frontends. The first one, Pleroma FE, can be reached by normally visiting the site. The other one, based on the Mastodon project, can be found by visiting the /web path of your site.
- * You will need to let pleroma instance to know what hostname/url it's running on.
+### As systemd service (with provided .service file)
+Example .service file can be found in `installation/pleroma.service` you can put it in `/etc/systemd/system/`.
+Running `service pleroma start`
+Logs can be watched by using `journalctl -fu pleroma.service`
- In file `config/dev.exs`, add these lines at the end of the file:
+### As OpenRC service (with provided RC file)
+Copy ``installation/init.d/pleroma`` to ``/etc/init.d/pleroma``.
+You can add it to the services ran by default with:
+``rc-update add pleroma``
- ```elixir
- config :pleroma, Pleroma.Web.Endpoint,
- url: [host: "example.tld", scheme: "https", port: 443]
- ```
+### Standalone/run by other means
+Run `mix phx.server` in repository's root, it will output log into stdout/stderr
- 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 HTTPS certificates, you can look into letsencrypt.
+### Using an upstream proxy for federation
- * (not tested with reboots!) 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/` and run it by `service pleroma start`; You can watch logs by using `journalctl -u pleroma.service`;
+Add the following to your `dev.secret.exs` or `prod.secret.exs` if you want to proxify all http requests that pleroma makes to an upstream proxy server:
- * Without systemd you can start Pleroma by starting Phoenix endpoint with `mix phx.server`
- it should be available on 4000 port on localhost and proxied to 443 port by nginx.
+ config :pleroma, :http,
+ proxy_url: "127.0.0.1:8123"
+This is useful for running pleroma inside Tor or i2p.
