Deploy with AWS

Deploying Rocket.Chat on Amazon Web Services

By leveraging Amazon Web Services (AWS) to deploy. Rocket.Chat on an EC2 instance, organizations can unlock a host of benefits, from scalability and reliability to cost-effectiveness and simplified management

Preparation Steps

The minimum requirement to run Rocket.Chat successfully is 2Gb 2 cores. You need an active AWS account to proceed with the deployment.

It is not recommended to use this method for large production. Instead, see how to deploy on .

In this guide, you'll learn how to:

Host Rocket.Chat on an EC2 instance with a domain name.
Secure your Rocket.Chat server with a free SSL certificate from .

Deploy Rocket.Chat on an EC2 instance

Launch an EC2 Instance

To create a new EC2 instance:

Log into your , and open the EC2 Service.
From the sidebar, click Instances. Then, click Launch Instances to set up a new EC2 instance.
Set the instance name and select at least Ubuntu Server 18.04 LTS" with "64-bit (x86) architecture as the OS image.
Select an instance type of your choice according to the Cores recommendation above.
Choose an existing key pair or create a new one for SSH connections.
Adjust the instance details as needed or keep the defaults.
Adjust the storage size and configuration as required.
Make sure to add a tag called Name and assign a value.
Allow SSH, HTTP, and HTTPS in the security group configuration, and proceed with Review and Launch.
After confirming your instance configuration, Launch Instance.

Allocate an Elastic IP

Next, allocate an IP address to the EC2 instance. To allocate an elastic IP,

Click Allocate Elastic IP address.
Select Amazon's pool of IPv4 addresses, and click Allocate.
Click and open the newly created IP address and select Associate Elastic IP address.
Select your instance and click Associate.
In the details below, copy the Public DNS. You will need it to configure the DNS. The format looks like this: ec2-18-XXX-XXX-XXX.eu-central-1.compute.amazonaws.com

Configure DNS with AWS Route 53

To make your workspace accessible on the internet, you will require a domain name that people can use to access it.

Open the Route 53 service dashboard and navigate to Hosted Zones.
Click Create Hosted Zone.
Enter your domain name and select Public Hosted Zone as the type. Click the Create hosted zone button.
Select your newly created zone and click Create Record Set.
Enter "www" as a subdomain (if desired), select Type CNAME, enter the Public DNS name you copied from the elastic IP to the value field, and click "Create."

Get an SSL Certificate from Let's Encrypt

Use Let's Encrypt to get a free & open-source SSL certificate:

SSH to your instance.

ssh -i <path_to_key_file.pem> ubuntu@<public_ip_address>

If your DNS has resolved, you may replace the Ip address with your domain name.

Install certbot using apt:

sudo apt update
sudo apt install certbot

Obtain a certificate from Let's Encrypt by running this command:

sudo certbot certonly --standalone --email <emailaddress@email.com> -d <domain.com> -d <subdomain.domain.com>

A second (or more) domain is optional.

Restrict access using security groups.

If you want to restrict traffic to your AWS instance, you may adjust the security groups again. Make sure you allow "TCP/22" from your current location for the SSH connection, as well as "TCP/443" from the location you wish to use to access from.

Configure Nginx Web Server with TLS/SSL

Rocket.Chat is set to run on port 3000 by default. However, you can use Nginx as a reverse proxy to link your domain name to the Rocket.Chat server running on that port. This way, your users can access your workspace through your domain name(example.com), instead of directly using the port in the URL(example.com:3000).

Install Nginx web server:

 sudo apt-get install nginx

Backup the default config file for reference:

 cd /etc/nginx/sites-available
 sudo mv default default.reference

Create a new site configuration for Rocket.Chat:

 sudo nano /etc/nginx/sites-available/default

 server {
     listen 443 ssl;

     server_name <ABC.DOMAIN.COM>;

     ssl_certificate /etc/letsencrypt/live/<ABC.DOMAIN.COM>/fullchain.pem;
     ssl_certificate_key /etc/letsencrypt/live/<ABC.DOMAIN.COM>/privkey.pem;
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
     ssl_prefer_server_ciphers on;
     ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';

     root /usr/share/nginx/html;
     index index.html index.htm;

     # Make site accessible from http://localhost/
     server_name localhost;

     location / {
         proxy_pass http://localhost:3000/;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_set_header Host $http_host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto http;
         proxy_set_header X-Nginx-Proxy true;
         proxy_redirect off;
     }
 }

 server {
     listen 80;

     server_name <ABC.DOMAIN.COM>;

     return 301 https://$host$request_uri;
 }

Ensure to update ABC.DOMAIN.COM with your domain name. Update it in the path to your key files as well.

Test the Nginx configuration to make sure there are no syntax errors

sudo nginx -t

If the syntax test went successful, restart Nginx:

sudo systemctl restart nginx

Confirm it is running correctly by opening a web browser and entering your domain name. A "502 Bad Gateway" page is expected since the Rocket.Chat backend is not yet running. Ensure the SSL connection works appropriately by clicking the lock icon next to the address bar. Confirm it's valid and issued by "Let's Encrypt Authority X3".
