Deploy on Kali

Preparation Steps

Install necessary dependencies

  • 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.

Install the Node and MongoDB versions required for the Rocket.Chat release you intend to install.

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 on Kali

  • Download and extract the latest Rocket.Chat version with these commands:

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

  • Install NPM.

When executing npm install, it is recommended to operate using a non-root account. Alternatively, you can utilize the npm install --unsafe-perm command. This approach eliminates the necessity for building libc or upgrading the host system.

cd /tmp/bundle/programs/server && npm install

This guide uses /opt but feel free to choose a different directory.

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
[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target nginx.service mongod.service
[Service]
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
User=rocketchat
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
[Install]
WantedBy=multi-user.target
EOF

  • 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

  • Enable and start MongoDB with the following command

sudo systemctl enable mongod && sudo systemctl start mongod

  • Then, initiate replica set with this command:

mongo --eval "printjson(rs.initiate())"

  • Enable and start your Rocket.Chat workspace now using this command:

sudo systemctl enable rocketchat && sudo systemctl start rocketchat

Configure your Rocket.Chat server

To access your Rocket.Chat workspace, open a web browser and navigate to the specified ROOT URL (http://your-host-name.com-as-accessed-from-internet:3000). Follow the configuration prompts to configure your workspace.
