   3 ## About Pleroma
   4
   5 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.
   6
   7 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).
   8
   9 Mobile clients that are known to work well:
  10
  11 * Twidere
  12 * Tusky
  13 * Pawoo (Android + iOS)
  14 * Subway Tooter
  15 * Amaroq (iOS)
  16 * Tootdon (Android + iOS)
  17 * Tootle (iOS)

  19 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.

  21 ## Installation
  22
  23 ### Docker
  24
  25 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.
  26
  27 ### Dependencies
  28
  29 * Postgresql version 9.6 or newer
  30 * 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).
  31 * Build-essential tools
  32
  33 ### Configuration
  34
  35   * Run `mix deps.get` to install elixir dependencies.
  36
  37   * 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.
  38
  39   * 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`.
  40
  41   * Run `mix ecto.migrate` to run the database migrations. You will have to do this again after certain updates.
  42
  43   * 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.
  44
  45   * 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/
  46   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.
  47
  48 ## Running
  49
  50 * 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.
  51
  52 ### Frontends
  53 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.
  54
  55 ### As systemd service (with provided .service file)
  56 Example .service file can be found in `installation/pleroma.service` you can put it in `/etc/systemd/system/`.
  57 Running `service pleroma start`
  58 Logs can be watched by using `journalctl -fu pleroma.service`
  59
  60 ### As OpenRC service (with provided RC file)
  61 Copy ``installation/init.d/pleroma`` to ``/etc/init.d/pleroma``.
  62 You can add it to the services ran by default with:
  63 ``rc-update add pleroma``
  64
  65 ### Standalone/run by other means
  66 Run `mix phx.server` in repository's root, it will output log into stdout/stderr
  67
  68 ### Using an upstream proxy for federation
  69
  70 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:
  71
  72     config :pleroma, :http,
  73       proxy_url: "127.0.0.1:8123"
  74
  75 This is useful for running pleroma inside Tor or i2p.
  76
  77 ## Troubleshooting
  78
  79 ### No incoming federation
  80
  81 Check that you correctly forward the "host" header to backend. It is needed to validate signatures.
