In this tutorial, you’ll learn how to install ERPNext 15 on Debian 13 from scratch including all dependencies, system configuration, database tuning, production setup and install an SSL certificate.

Step 1: Update Operating System

First check the server’s current time zone with the following command:

# date

Then Set correct time zone as per your region with the following command:

# timedatectl set-timezone "America/Chicago"

This is a important step as it impacts the ERPNext usage.

Then update your Debian 13 operating system to the latest version with the following command:

# apt update && apt upgrade

This ensures all dependencies are up-to-date and prevents conflicts later.

Step 2: Install Required Dependencies

In this step we will install the required system-level packages for the system to work correctly.

# apt install -y git curl wget sudo certbot

Also, ERPNext needs several Python packages to build Python modules and run Frappe.

# apt install -y python3 python3-dev python3-setuptools python3-pip python3-venv libffi-dev libssl-dev libsasl2-dev

These libraries allow Frappe to compile PDF rendering, image processing, database drivers, and more.

Step 3: Add a new user

Now we will create a dedicated user for your ERP application. This user will be assigned admin permissions and will be used as the main Frappe Bench user:

# /sbin/adduser erpnext

To add the user to the sudo group, use the usermod command as follows:

# /sbin/usermod -aG sudo erpnext

Then log in as the new user:

# su - erpnext

Step 4: Install MariaDB

You can install the MariaDB server with the following command:

$ sudo apt install -y mariadb-server mariadb-client

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

$ sudo systemctl start mariadb
$ sudo systemctl enable mariadb

Verify the status of the MariaDB service using systemctl status command:

$ sudo systemctl status mariadb

By default, MariaDB is not hardened. You can secure MariaDB using the mariadb-secure-installation script.

$ sudo mariadb-secure-installation

Configure it like this:

- Set root password? [Y/n] Y
- Remove anonymous users? [Y/n] Y
- Disallow root login remotely? [Y/n] Y
- Remove test database and access to it? [Y/n] Y
- Reload privilege tables now? [Y/n] Y

Step 5: Install Node.js

Run the following command to install Node.js:

$ sudo apt install nodejs npm

You can verify the installation by running the following command:

$ node --version

You should see the version number of Node.js installed on your system:

v20.19.2

Then verify the npm version with the following command:

$ npm --version

You should get the following output:

9.2.0

ERPNext uses Yarn for building frontend assets.

$ sudo npm install -g yarn

Step 6: Install Redis Server

Redis handles caching and web socket communication for real-time features.

$ sudo apt install -y redis-server
$ sudo systemctl enable --now redis-server

Step 7: Install Frappe Bench

Bench is the command-line tool used to manage ERPNext installations. Use the following commands to install the Bench CLI:

$ sudo apt remove python3-requests
$ sudo python3 -m pip config set global.break-system-packages true 
$ sudo pip3 install frappe-bench 

Confirm installation:

 $ bench --version

You should get the following output:

5.27.0

Now initialize a new Bench directory:

$ bench init frappe-bench --frappe-branch version-15
$ cd frappe-bench

This creates a full environment with Python virtualenv and node tools.

Now change user directory permissions. This will allow execution permission to the home directory of the frappe user.

chmod -R o+rx /home/erpnext/

Create a new Frappe site with the following command:

$ bench new-site erp.yourdomain.com

You will be prompted for:

• MySQL root password
• ERPNext administrator password

Step 8: Install ERPNext and other Apps

Finally, we’re at the last stage of the installation process!

Download the payments apps . This app is required during ERPNext installation

 $ bench get-app payments

Download the main ERPNext app with the following command:

$ bench get-app --branch version-15 erpnext

Download the HR & Payroll app (optional)

$ bench get-app hrms

Check if all the apps are correctly downloaded by running:

$ bench version --format table

Now install it on your site:

$ bench --site erp.yourdomain.com install-app erpnext

Install the HR & Payroll app (optional)

$ bench --site erp.yourdomain.com install-app hrms

Step 9: Test ERPNext in Development Mode (Optional)

You can launch a development server with the following command:

$ bench start

You can access ERPNext at:

http://YOUR_SERVER_IP:8000

Step 10: Setting ERPNext in Production Mode

For the production environment, we need to configure Nginx and Supervisor to keep application running in background.

You can install them with the following command:

$ sudo apt install nginx supervisor

Enable scheduler service

$ bench --site erp.yourdomain.com enable-scheduler

Disable maintenance mode

bench --site erp.yourdomain.com set-maintenance-mode off

Setup production config

$ sudo bench setup production erpnext

Restart Supervisor

$ sudo supervisorctl restart all

Step 11: Custom Domain & SSL Setup

For SSL configuration, you can run the following commands:

$ bench config dns_multitenant on
$ sudo bench setup lets-encrypt erp.yourdomain.com

Step 12: Access your ERPNext Application

Open your browser and type your domain e.g https://erp.yourdomain.com
