Install Chatwoot on Ubuntu 20.04

In this tutorial, we will show you how to install Chatwoot on Ubuntu 20.04 LTS. For those of you who didn’t know, Chatwoot is an open-source, real-time messaging platform that also provides simple and elegant live chat for your websites, collaborates with other agents and messaging apps, and more. This means that you can integrate your social media chat e.g Facebook, Twitter, email, WhatsApp e.t.c to one central place. This will effectively help you have eyes on all your platforms and respond to customer requests in real-time.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Chatwoot on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Chatwoot on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Chatwoot on Ubuntu 20.04.

Now we download the script that will be used to install Chatwoot:

cd /tmp
wget -O

Next, make it executable and then install using the commands below:

sudo chmod 755
sudo ./ master

Once a successful installation, you should see a message similar to the one below:

Chatwoot server installation is complete
The server will be accessible at http://<server-ip>:3000
To configure a domain and SSL certificate, follow the guide at

Step 3. Install and Configure Nginx Web Server.

Now we need to install Nginx and use it as a reverse proxy for Chatwoot:

sudo apt update
sudo apt install nginx

After installing Nginx, run the command below to unlink the default Nginx configuration file:

sudo unlink /etc/nginx/sites-enabled/default

Next, create a new Nginx virtual host configuration:

cd /etc/nginx/sites-available
sudo nano chatwoot.conf

Add the following configuration in the conf file:

# server {

# Point upstream to Chatwoot App Server
set $upstream;

# Nginx strips out underscore in headers by default
# Chatwoot relies on underscore in headers for API
# Make sure that the config is turned on.
underscores_in_headers on;
location /.well-known {
alias /var/www/ssl-proof/chatwoot/.well-known;

location / {
proxy_pass_header Authorization;
proxy_pass http://$upstream;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Ssl on; # Optional

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_http_version 1.1;
proxy_set_header Connection “”;
proxy_buffering off;

client_max_body_size 0;
proxy_read_timeout 36000s;
proxy_redirect off;
listen 80;

Save the configuration file and link it to /etc/nginx/sites-enabled:

sudo ln -s /etc/nginx/sites-available/chatwoot.conf /etc/nginx/sites-enabled/chatwoot.conf

Verify that your Nginx configuration is okay then restart the Nginx service:

sudo nginx -t
sudo systemctl reload nginx

Step 4. Installing and Configure Let’s Encrypt SSL.

We should enable a secure HTTPS connection on Chatwoot. We can obtain a free TLS certificate from Let’s Encrypt. Install Let’s Encrypt client (certbot) from Ubuntu 20.04 repository:

sudo add-apt-repository ppa:certbot/certbot

Now install Certbot:

sudo apt update
sudo apt install python-certbot-nginx

Run Let’s Encrypt using the following command:

sudo mkdir -p /var/www/ssl-proof/chatwoot/.well-known
sudo certbot --webroot -w /var/www/ssl-proof/chatwoot/ -d -i nginx

Step 5. Accessing Chatwoot Web Interface.

Chatwoot will be available on HTTP port 80 by default. Open your favorite browser and navigate to and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
