Matrix - ArchWiki

# Matrix

Matrix is an ambitious new ecosystem for open federated Instant Messaging and VoIP. It consists of servers, clients and bridge software to connect to existing messaging solutions like IRC.

## Installation

The reference server implementation Synapse is available in the community repository as matrix-synapse. Synapse does not run on Python 3 and requires version 2.7. The community package creates a synapse user.

## Configuration

After installation, a configuration file needs to be generated. It should be readable by the synapse user:

    $ cd /var/lib/synapse
    $ sudo -u synapse python2 -m synapse.app.homeserver \
      --server-name my.domain.name \
      --config-path /etc/synapse/homeserver.yaml \
      --generate-config \
      --report-stats=yes

Note that this will generate corresponding SSL keys and self-signed certificates for the specified server name. You have to regenerate those if you change the server name.

### Webclient

The default synapse configuration enables the webclient feature. Unless you have python2-matrix-angular-sdk installed this will make synapse fail to start. Either disable it, or install python2-matrix-angular-sdk.

Note: From the developers website: Matrix.org’s original reference AngularJS webclient has major performance issues and is not being actively maintained. Please see Riot and matrix-react-sdk for better alternatives.

## Service

A systemd service named synapse.service will be installed by the matrix-synapse package. It will start the synapse server as user synapse and use the configuration file `/etc/synapse/homeserver.yaml`.

## User management

You need at least one user on your fresh synapse server. You may create one as your normal non-root user with the command

    $ register_new_matrix_user -c /etc/synapse/homeserver.yaml https://localhost:8448

or using one of the matrix clients
