Mattermost installation and settings

Until there is a Fedora package for Mattermost, we choose to install the build folder in /opt.

1- download the last version

2- Create a system user and group that will run the service

# useradd -r -s /bin/bash mattermost -U

3- give acces rights

# chown -R mattermost:mattermost /opt/mattermost/data

4- edit

# vim /opt/mattermost/config/config.json

5- check the connection

$ cd /opt/mattermost/bin
# ./Platforms

If everything is OK, you will see after some initialization lines:

Server is listening on :8065
