Rocket.Chat on Kali Linux

Since Kali is a Debian distribution, the installation process is quite similar.

Requirements

Depending on the version of Rocket.Chat you want to install, check the release notes to see the supported engine versions for MongoDB and NodeJs, and install as recommended.

  • MongoDB

    Please refer to the official MongoDB documentation on installing MongoDB on Debian.

  • NodeJS

    Follow the official guide to install NodeJS on Debian. You can also use third-party tools like nvm or n.

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

Install necessary dependency packages

  • Update the 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 the 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 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

  • 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 NPM.

{% hint style="info" %} This guide uses /opt but feel free to choose a different directory. {% endhint %}

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

Configure the Rocket.Chat service

  • Add the rocketchat user and set the right permissions on the Rocket.Chat folder.
sudo useradd -M rocketchat && sudo usermod -L rocketchat
sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat
  • Create the Rocket.Chat service file.
cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service

  • Open the service file (/lib/systemd/system/rocketchat.service) using sudo and update the ROOT_URL environmental variable to reflect the URL you are using to access the server. Optionally, you can 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
  • Set up storage engine and replication for MongoDB. 
sudo sed -i "s/^#  engine:/  engine: wiredTiger/"  /etc/mongod.conf
sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf

Then, enable and start MongoDB and Rocket.Chat.

sudo systemctl enable mongod && sudo systemctl start mongod
mongo --eval "printjson(rs.initiate())"
sudo systemctl enable rocketchat && sudo systemctl start rocketchat

Optional configurations

You might also want to add the following optional configurations:

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 up an admin account and your organization and server info.
