Pleroma

Installation

Dependencies

• Postgresql version 9.5 or newer
• Elixir version 1.4 or newer
• NodeJS LTS

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.

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

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
• 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.

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: (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:

  \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")

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:

  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 HTTPS certificates, you can look into letsencrypt.

• (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;

• 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.
