Installation/Backport

Note:

This page merely exists to fill some open holes while all older guides are rewritten for the new installation guides form

Introduction

Note:

You don't need to have your own pod to use diaspora*.
Running your own diaspora* server allows more control over your data, but it requires technical skills and time. Instead, you can register on one of the installations open to everyone that allow you to use diaspora* in a few clicks without any requirements

This guide will outline the procedure to get you set up with a production-ready installation of diaspora*.

Things to know

The install is a bit complex, but we're here to help.
It's extremely helpful to have some experience in Linux/Unix server administration or Rails app deployment already. But don't worry, if you run into problems and need help, just visit us in our IRC channels on Freenode.
Running a common setup will get you the most help, if you need it.
Most people in the community will have some experience running diaspora* with Unicorn as the app server using Nginx as outward-facing web server. Of course, you're free to run any other app server (Thin, Passenger...) or web server (Apache), but you might find it harder to get help if you run into unexpected troubles.
diaspora* is developed utilizing latest web standards
Therefore UX is best with recent browsers, so please update your Firefox, Opera, Chrome or Safari to the newest version. We do not currently support any version of Internet Explorer, though we won't reject any contributions attempting to change that circumstance.
diaspora* strongly recommends HTTPS
as we encrypt communication amongst servers and to the client browsers. You can get a free TLS certificate from Let's Encrypt.
Unfortunately, self-signed certificates or certificates issued by CACert won't work.
We need your feedback
to constantly improve and update this guide. Have a look at How we communicate
Do not run any of the commands you find in this guide as root (except if requested).
Just use your normal user - or even better - create a separate user for diaspora* (rationale).

Versions of this guide

Warning:

Make sure to use the correct version of the guide, see below.

» Help me decide!

In Production mode, your pod is configured to deal with high load for everyday usage. This is recommended for a pod you want to actually use.

In Development mode, your pod is configured for development. This is recommended ony for development contributors of diaspora* which use the pod only locally for testing purposes.

For Database, choose PostgreSQL unless you already have an existing database server that you want to re-use. We recommend an isolated PostgreSQL installation exclusively for your pod.

The current guide is for a production setup with PostgreSQL as database.

You can change them below:

Running mode: Production | Development

Database: PostgreSQL | MySQL (deprecated) | MariaDB (deprecated)

Requirements

Hardware

Minimum recommended:

Memory: 1.5 GB
Swap: 1 GB
CPU: decent multicore
Storage: The amount of hard disk space required largely depends on how many images you expect your users to upload.

It is possible to run a pod on a Raspberry Pi >= 2. However, this will be very slow and is not recommended for multi-user pods.

Software

Over the course of this manual, you will install the following software if not already installed.

Build tools - for compiling source packages
Ruby - the Ruby programming language
RubyGems - package manager for Ruby code libraries (like CPAN for Perl or PEAR for PHP)
Bundler - gem management tool for Ruby projects
MySQL or MariaDB or PostgreSQL - backend storage engine
OpenSSL - encryption library.
libcurl - multiprotocol file transfer library WARNING: Due to sidekiq longjmp error, you need at least curl 7.32
ImageMagick - image processing library
Git - version control system
Redis - persistent key-value store
one of the JavaScript runtimes on execjs' supported list.

Please note that running diaspora* together with other applications that use Redis on the same machine can be dangerous. Only do that if you absolutely know what you are doing, and if you know how to change the Redis database for all of the applications.

Prepare the system

Old guide placeholder

This is the part were you should follow the old OS specific guide.

Get the source

It's time to download diaspora*! As your diaspora user run:

cd ~
git clone -b main https://github.com/diaspora/diaspora.git
cd diaspora

Don't miss the cd diaspora, all coming commands expect to be run from that directory!

Configuration

Copy files

cp config/database.yml.example config/database.yml
cp config/diaspora.toml.example config/diaspora.toml

Now open config/database.yml and config/diaspora.toml in your favorite text editor and carefully review them, they are extensively commented.

Important values in config/database.toml

username Make sure to use the right username you created for diaspora.
password Make sure to use the right password for the user your created for diaspora.

Important values in config/diaspora.toml

configuration.environment.url: Set the public facing URL to your pod here, for example for https://pod.geraspora.de this would be https://pod.geraspora.de
configuration.environment.certificate_authorities: You have to set this, one of the examples should fit. If the file in the example doesn't exist you're missing a package, in most cases it's named ca-certificates.
configuration.server.rails_environment: You must set this to production. The server section is read by ./script/server and most alternative startup methods to setup the correct environment.
environment.require_ssl: If for some reason you can't run your pod on HTTPS (we highly encourage you to do it!), set this to false to prevent a redirect from http:// to https://

Bundle

It's time to install the Ruby libraries required by diaspora*:

script/configure_bundler
bin/bundle install --full-index

This takes quite a while. When it's finished, you should see a message similar to: Bundle complete! 137 Gemfile dependencies, 259 gems now installed. If that's not the case, you should seek for help on the mailing list or the IRC channel.

Running the manual gem install command shown in the error message can sometimes show a clearer error message if the bundle command fails.

Database setup

Double check your config/database.yml looks right and run:

RAILS_ENV=production bin/rake db:create db:migrate

Precompile assets

RAILS_ENV=production bin/rake assets:precompile

Start diaspora*

It's time to start diaspora*:

./script/server

Your diaspora server is now running, either on a unix socket (current default) or on http port 3000. The listening method can be configured in diaspora.toml, search for '3000' or 'listen' to find the correct line.

The server script is good to ensure your server works as expected. You should set up automatic startup for your pod, so that your pod automatically starts on server reboots, and recovers from eventual crashes.

Reverse proxy

To connect the internet to diaspora*, and to serve static files, you need to set up a reverse proxy. We highly recommend nginx, and you can find an example configuration for nginx here.

Alternatives to nginx (not recommended)

Alternatively, you can check out these community-contributed options. However, please note that we will have a hard time supporting you if you run into issues with them!
