How to install Rocket.Chat server on a Raspberry Pi

Rocket.Chat is the leading free and open source team communication platform

Key features include free audio and video conferencing, guest access, screen and file sharing, LiveChat, LDAP Group Sync, two-factor authentication (2FA), E2E encryption, SSO, dozens of OAuth providers and unlimited users, guests, channels, messages, searches and files." - from the Rocket.Chat website

  • Create a startup service file for Rocket.Chat.
cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service
[Unit]
Description=The Rocket.Chat server

  • Open the Rocket.Chat service file just created (/lib/systemd/system/rocketchat.service) using sudo and your favourite text editor, and change the ROOT_URL environmental variable to reflect the URL you want to use for accessing the server (left on localhost works)
  • Edit MongoDB conf settings and start services
sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
sudo sed -i "s/bindIp/#bindIp/"  /etc/mongod.conf
sudo systemctl enable mongod && sudo systemctl start mongod
mongo --eval "printjson(rs.initiate())" 
sudo systemctl enable rocketchat && sudo systemctl start rocketchat
  • Takes a couple of minutes to be fully operational.
  • If you make any changes to the config or service files for Mongo or Rocket run the following to updated changes and then restart the service/s
sudo systemctl daemon-reload 
  • To configure your Rocket.Chat server use a browser and connect to:
http://<YourPiIP>:3000
  • or using zeroconf use hostname.local
http://com1.local:3000
  • Connect Rocket.Chat on Phones
http://<YourPiIP>:3000
