Setting up a RocketChat Server on Ubuntu

1. Overview

RocketChat is an open-source team chat client, similar to other team chat solutions such as Slack and Mattermost. It can be self-hosted, supports voice & video chat, and has apps for all popular platforms (web, Windows, macOS, Linux, Android and iOS).

What you’ll learn

This tutorial will teach you how to setup and configure a RocketChat server on Ubuntu.

What you’ll need

  • Ubuntu Server 16.04 or greater
  • Basic command-line knowledge

How will you use this tutorial?

What is your current level of experience with RocketChat?

2. Installation

First, we need to install RocketChat. Luckily, there’s a RocketChat snap that can easily be installed using Snapcraft. Snaps are easy to install, isolated from the rest of your system, and auto-updated.

Installing the Snap

Thanks to Snapcraft, the installation is extremely simple. Install the Snap with the following command:

snap install rocketchat-server

Accessing your server

By default, your server will be available on port 3000. You can access this by going to serverIP:3000 (replacing ‘serverIP’ with your server’s IP address) in your web browser, or localhost:3000 if you’re running the server locally. You should be greeted by the following screen:

Now that your server is setup, you can actually start using it! In the next sections, we’ll cover basic usage and configuration of your server.

3. Basic usage

Creating an account

First, you’ll have to create an account. The first account created on the server will automatically become an admin, which will allow you to configure the server.

Click on Register a new account. You’ll be shown a screen where you must enter your name, email and password.

The Name field on this page is not your username!
Your username will be chosen on the next page. The Name field on this page should be your actual name, so your team members can identify you.

RocketChat account registration page

After registering, you will be logged in automatically. By default there will be one channel (#general), and there should be a message showing that you joined. There should be badge beside your name, indicating that you’re an admin, as shown below:


In the left sidebar, there is a list of channels. You can switch to a channel by clicking on it. A channel is essentially a seperate chat room made for a specific topic with different sets of people.

Creating a channel

A channel may be created by clicking on the plus sign beside the search bar. Channels may be private and require an invite, or public for anyone in your team to join. Channel names may only include lowercase letters, numbers and dashes.

Sending direct messages

You may send direct messages to team members by opening the member list (located on the right sidebar), clicking on someone’s name and clicking on the Conversation button. Past direct messages will appear on the left sidebar, under the list of channels.


Messages can be sent (quite intuitively) by typing in the chatbar and pressing enter. You may add attachments (files, video and audio), emoji, and apply basic formatting.

All messages have a menu that can be accessed by hovering over them and clicking on the series of dots that appear over it at the top-right corner. If you sent the message (or you have the proper permissions), you can edit or delete it. You can also star a message to save it for later, or, with the proper permissions, pin it to the channel to save it for everyone. Stars and pins can be accessed from the right sidebar.

Other features

From the right sidebar, you can also change notification preferences and see the file list for a channel. If you click on your name at the top-left, you will open a menu where you can change your status (online, away, etc), change your account settings, or (if you’re an admin), change server administration settings.

That’s a quick RocketChat primer. Now, let’s move on to server configuration!

4. Managing the RocketChat service

Your RocketChat server is managed through systemd services. By default, they start on boot and automatically restart on failure.

You can check the status of the RocketChat server service with the following command:

systemctl status snap.rocketchat-server.rocketchat-server.service

The output will look something like:

snap.rocketchat-server.rocketchat-server.service - Service for snap application rocketchat-server.rocketchat-server
   Loaded: loaded (/etc/systemd/system/snap.rocketchat-server.rocketchat-server.service; enabled; vendor preset: enabled)
   Active: active (running) since Sat 2017-12-09 23:36:30 EST; 1h 13min ago

The Active line tells us that the service is running. Say we want to stop the service:

systemctl stop snap.rocketchat-server.rocketchat-server.service

Now our server will be inaccesible, and if we check it’s status:

snap.rocketchat-server.rocketchat-server.service - Service for snap application rocketcha
   Loaded: loaded (/etc/systemd/system/snap.rocketchat-server.rocketchat-server.service; en
   Active: inactive (dead) since Sun 2017-12-10 00:54:25 EST; 1min 15s ago

As you can see, the Active line now says inactive.

To start the server again, we can run the above command, replacing stop with start:

systemctl start snap.rocketchat-server.rocketchat-server.service

We can also restart the server directly, instead of stopping and starting it:

systemctl restart snap.rocketchat-server.rocketchat-server.service

The MongoDB database that powers your RocketChat server is ran by the snap.rocketchat-server.rocketchat-mongo.service service. You can use the same systemctl commands above to manage it.

5. Changing port and enabling SSL

RocketChat uses Caddy as it’s HTTP server. Before we can change it’s settings, we need to generate a config file. We can generate the default config with:


The output will be similar to the following:

Replace /var/snap/rocketchat-server/1195/Caddyfile with your own to customize reverse proxy

Edit the file with your favourite editor (such as Vim or Nano). It should look like the following:

proxy / localhost:3000 {

If you want to change the port or enable SSL, change the first line to your domain name. For example, if our domain is, we would change the file to:
proxy / localhost:3000 {

You can also change the port. For example, to use the port 3001, we change the first line of our config file to

If you’re running the server locally, you can replace the domain with localhost.
In the example above, we would change the first line to localhost:3001.

By leaving the http or https out of the domain, HTTP requests will automatically be redirected to HTTPS.

When you change the domain or port, you must also change the Site URL setting in RocketChat.
The next time an admin logs in after the domain or port changes, RocketChat will prompt them to automatically change the Site URL. You can also change this manually in the server administration settings.

6. Conclusion

Congratulations, you now have a RocketChat server ready to go for your team! RocketChat has a lot of features, and this was just a brief introduction. If you want to learn more about general usage, server administration or contributing to RocketChat, check out the RocketChat documentation.
