Rocket.Chat on Kali Linux
This installation guide was tested in the following environment:
  • Rocket.Chat 3.9.0
  • OS: Kali Rolling 2020.2
  • Mongodb 4.0.19
  • NodeJS 12.18.4
As from Rocket.Chat 4.4.0, NodeJS version 14.x.x is used.
As Kali is a distribution based on Debian the installation process is pretty the same, only adding some MongoDB dependencies installation.

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:// --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
echo "deb 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 | sudo bash -
Install build tools, MongoDB and dependencies (libcurl3 and mongoDB server), nodejs and graphicsmagick:
sudo apt-get install -y build-essential libcurl3 mongodb-org-server 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 12.18.4

Install Rocket.Chat

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
Description=The Rocket.Chat server nginx.service mongod.service
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01 MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01 ROOT_URL=http://localhost:3000/ PORT=3000
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):
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
