Deploy on Debian

Preparation Steps

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.

  • Install MongoDB

    Please refer to the official MongoDB documentation on how to install MongoDB on Debian. For the list of supported versions, see our documentation here.

  • Install NodeJS

    Follow the official guide to install NodeJS on a Debian system. Check out our page on supported node versions for your specific version. You can also use third-party tools like nvm or n.

Install Rocket.Chat on Debian

  • Update your system by running this command:
sudo apt -y update
sudo apt -y upgrade
  • Install required packages/dependencies:
sudo apt install -y curl build-essential graphicsmagick
  • To download the latest Rocket.Chat version run the following command:
curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz

You can also use wgetto download Rocket.Chat with this command:

wget https://releases.rocket.chat/latest/download -O /tmp/rocket.chat.tgz

To download a specific version, replace latest the version number.

wget https://releases.rocket.chat/4.1.2/download -O /tmp/rocket.chat.tgz
  • Extract the archive with tar:
tar xzf /tmp/rocket.chat.tgz -C /tmp

You should now see a new directory under /tmp named bundle.

  • Next, install all the node dependencies:

{% hint style="warning" %} 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. {% endhint %}

(cd /tmp/bundle/programs/server; npm i)

/tmp has been a temporary non-root user-writable location to prepare the bundle. For this guide, we're going to use /opt to be the final location but you can choose any other. Whatever may it be, if not /opt, make sure you change the location in all the other places it is specified.

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
  • Create the Rocket.Chat service file:
sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat
  • Depending on how you install NodeJS, the binary path may be different. Save the path to a variable.
NODE_PATH=$(which node)
  • Now, save the systemd service file.
cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service
[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target nginx.service mongod.service
[Service]
ExecStart=$NODE_PATH /opt/Rocket.Chat/main.js
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
User=rocketchat
[Install]
WantedBy=multi-user.target
EOF

The command above will create a barebone service file, this service file is what systemd will use to start your Rocket.Chat daemon/process.

Passing environment variables

  • Pass some environment variables to the running process. See Rocket.Chat environmental variables for more details. To update the Rocket.Chat file, run the following command :
sudo systemctl edit rocketchat
  • Update the text editor with the information below and save.
[Service]
Environment=ROOT_URL=http://localhost:3000
Environment=PORT=3000
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01
Environment=MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01

MongoDB Configuration

  • Open the MongoDB config file (/etc/mongod.conf) in your preferred text editor. 
nano /etc/mongod.conf
  • Set the storage engine to wiredTiger.
storage:
  engine: wiredTiger
  • Enable replication, and name the replicaset rs01.
replication:
  replSetName: rs01

{% hint style="warning" %} The MongoDB replica set is mandatory for Rocket.Chat > 1.0.0. {% endhint %}

Your MongoDB config file should look something like the following:

storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
  engine: wiredTiger

systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

net:
  port: 27017
  bindIp: 127.0.0.1

processManagement:
  fork: true
  timeZoneInfo: /usr/share/zoneinfo

replication:
  replSetName: rs01

{% hint style="info" %} Read the official documentation for a complete list of available MongoDB config options. {% endhint %}

  • Start MongoDB with the following command:
sudo systemctl enable --now mongod
  • Then, initiate replica set with this command:
mongo --eval "printjson(rs.initiate())"
  • You can start your Rocket.Chat workspace now using this command:
sudo systemctl enable --now 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.
