Template:Installation/Requirements

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

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.
