# Pleroma
-## Installation
+**Note**: This readme as well as complete documentation is also available at <https://docs-develop.pleroma.social>
-### Dependencies
+## About Pleroma
-* Postgresql version 9.6 or newer
-* Elixir version 1.4 or newer
-* NodeJS LTS
-* Build-essential tools
+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.
-#### 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 since Debian allows multiple versions to coexist but still runs only one version.
+Pleroma is written in Elixir, high-performance and can run on small devices like a Raspberry Pi.
-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 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://docs.joinmastodon.org/api/guidelines/).
-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`
+- [Client Applications for Pleroma](https://docs-develop.pleroma.social/clients.html)
-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.
+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>.
-### Preparation
+## Installation
+**Note:** The guide below may be outdated and in most cases shouldn't be used. Instead check out our [wiki](https://docs.pleroma.social) for platform-specific installation instructions, most likely [Installing on Linux using OTP releases](https://docs.pleroma.social/otp_en.html) is the guide you need.
- * 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.
+### OS/Distro packages
+Currently Pleroma is not packaged by any OS/Distros, but feel free to reach out to us at [#pleroma-dev on freenode](https://webchat.freenode.net/?channels=%23pleroma-dev) or via matrix at <https://matrix.heldscal.la/#/room/#freenode_#pleroma-dev:matrix.org> for assistance. If you want to change default options in your Pleroma package, please **discuss it with us first**.
-### Database setup
+### Docker
+While we don’t provide docker files, other people have written very good ones. Take a look at <https://github.com/angristan/docker-pleroma> or <https://github.com/sn0w/pleroma-docker>.
- * 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:
+### Dependencies
- ```sql
- ALTER USER postgres with encrypted password '<PASSWORD>';
- ```
+* Postgresql version 9.6 or newer
+* Elixir version 1.7 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
- 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:
+### Configuration
- ```
- local all postgres peer
- ```
+* Run `mix deps.get` to install elixir dependencies.
+* Run `mix pleroma.instance gen`. This will ask you 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`, which you should run as the PostgreSQL superuser (i.e., `sudo -u postgres psql -f config/setup_db.psql`). It will create the database, user, and password you gave `mix pleroma.gen.instance` earlier, as well as set up the necessary extensions in the database. PostgreSQL superuser privileges are only needed for this step.
+* 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 [`docs/config.md`](docs/config.md) in the repository, or at the "Configuration" page on <https://docs-develop.pleroma.social/config.html>
+* Run `mix ecto.migrate` to run the database migrations. You will have to do this again after certain updates.
+* 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.
+* 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.
- to
+## Running
- ```
- local all postgres md5
- ```
+* 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.
- 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).
- * Open psql shell as postgres user: (as root) `su postgres -c psql`
- * Create a new PostgreSQL user:
+### Frontends
- ```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;
- ```
+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.
- * Again, change password in `config/dev.exs`, and change user to `"pleroma"` (line like `username: "postgres"`)
+### As systemd service (with provided .service file)
-### Some additional configuration
+Example .service file can be found in `installation/pleroma.service`. Copy this to `/etc/systemd/system/`. Running `systemctl enable --now pleroma.service` will run Pleroma and enable startup on boot. Logs can be watched by using `journalctl -fu pleroma.service`.
- * You will need to let pleroma instance to know what hostname/url it's running on.
+### As OpenRC service (with provided RC file)
- In file `config/dev.exs`, add these lines at the end of the 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
- 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.
- * [Not tested with system reboot yet!] You'll also want to set up Pleroma to be run as a systemd service. Example .service file can be found in `installation/pleroma.service` you can put it in `/etc/systemd/system/`.
+### Using an upstream proxy for federation
-## Running
+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:
-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.
+```elixir
+config :pleroma, :http,
+ proxy_url: "127.0.0.1:8123"
+```
-### As systemd service (with provided .service file)
-Running `service pleroma start`
-Logs can be watched by using `journalctl -fu pleroma.service`
+This is useful for running Pleroma inside Tor or I2P.
-### Standalone/run by other means
-Run `mix phx.server` in repository's root, it will output log into stdout/stderr
+## Customization and contribution
