Rocket.Chat on Debian

This installation guide was tested in the following environment:

  • Rocket.Chat 3.0.0
  • OS: Debian 9.7
  • Mongodb 4.0.9
  • NodeJS 12.14.0

Install necessary dependency packages

Update package list and configure apt to install the official MongoDB packages with the following repository file:

sudo apt-get -y update
sudo apt-get install -y dirmngr gnupg && sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
echo "deb http://repo.mongodb.org/apt/debian stretch/mongodb-org/4.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list

Configure Node.js to be installed via package manager:

sudo apt-get -y update && sudo apt-get install -y curl && curl -sL https://deb.nodesource.com/setup_12.x | sudo bash -

Install build tools, MongoDB, nodejs and graphicsmagick:

sudo apt-get install -y build-essential mongodb-org nodejs graphicsmagick

Using npm install inherits and n, and the node version required by Rocket.Chat:

sudo npm install -g inherits n && sudo n 12.14.0

Install Rocket.Chat

Download the latest Rocket.Chat version:

curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz
tar -xzf /tmp/rocket.chat.tgz -C /tmp

Install (this guide uses /opt but feel free to choose a different directory):

cd /tmp/bundle/programs/server && npm install
sudo mv /tmp/bundle /opt/Rocket.Chat

Configure the Rocket.Chat service

Add the rocketchat user, set the right permissions on the Rocket.Chat folder and create the Rocket.Chat service file:

sudo useradd -M rocketchat && sudo usermod -L rocketchat
sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat
cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service
[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target nginx.target mongod.target
[Service]
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat

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 (optionally change MONGO_URL, MONGO_OPLOG_URL and PORT):

MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01
MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01
ROOT_URL=http://your-host-name.com-as-accessed-from-internet:3000
PORT=3000

Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat:

sudo sed -i "s/^#  engine:/  engine: wiredTiger/"  /etc/mongod.conf
sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
sudo systemctl enable mongod && sudo systemctl start mongod
mongo --eval "printjson(rs.initiate())"
sudo systemctl enable rocketchat && sudo systemctl start rocketchat

Optional configurations

Configure firewall rule Configure a HTTP reverse proxy to access Rocket.Chat server [Configure mongo access control] [Configure production values for mongodb]

Configure your Rocket.Chat server

Open a web browser and access the configured ROOT_URL (http://your-host-name.com-as-accessed-from-internet:3000), follow the configuration steps to set an admin account and your organization and server info.
