The post How to Install ERPNext on Debian 13 is a critical stepping stone for any organization looking to adopt this powerful platform. Debian, renowned for its stability and adherence to open-source principles, provides an excellent foundation for running ERPNext. Debian 13, codenamed “Trixie,” represents the latest iteration, offering updated packages and enhanced security features, making it an ideal choice for a modern ERP deployment.

Prerequisites for a Smooth ERPNext Installation on Debian 13

A successful installation hinges on having the right environment. We strongly recommend preparing your system thoroughly.

System Requirements and Recommendations

While ERPNext can run on modest hardware, for optimal performance, especially with a growing user base and extensive data, we advocate for the following:

Hardware: A dedicated server or a robust virtual machine is advisable.
- CPU: At least a 2-core processor (quad-core recommended for production environments).
- RAM: A minimum of 4GB of RAM is essential. For larger deployments or heavy usage, 8GB or more is highly recommended.
- Storage: A minimum of 50GB of free disk space. SSDs are strongly preferred for significantly faster read/write operations, which directly impacts ERPNext’s responsiveness.
Operating System: Debian 13 (Trixie) is the target. Ensure it is fully updated.
Internet Connection: A stable and reasonably fast internet connection is required for downloading packages and dependencies.

Essential Package Updates and System Preparation

Before commencing the ERPNext installation, it is imperative to ensure your Debian 13 system is up-to-date and configured correctly. This step is fundamental for security and compatibility.

Updating the Package List and Upgrading Installed Packages

We begin by refreshing the local package index and then upgrading all installed packages to their latest available versions. This ensures that you are working with the most recent and secure software components.

sudo apt update
sudo apt upgrade -y

The apt update command downloads the package information from all configured sources. The apt upgrade command then installs the newer versions of the packages you have installed. The -y flag automatically answers “yes” to any prompts, making the process non-interactive.

Installing Essential System Utilities

Several core utilities are often required for system administration and software compilation. We will install these to ensure a smooth environment.

sudo apt install -y git curl wget vim nano

git: Essential for version control and for cloning the ERPNext repository.
curl & wget: Used for downloading files from the internet.
vim & nano: Text editors for modifying configuration files.

Setting the Hostname

A correctly configured hostname is crucial for network services and application identification. We’ll ensure your system’s hostname is set appropriately.

Check Current Hostname:
```
hostname
```
Edit Hostname Configuration: Open the /etc/hostname file with your preferred editor:
```
sudo nano /etc/hostname
```
Ensure it contains your desired hostname (e.g., erpnext.yourdomain.com). Save and exit the file.
Edit Hosts File: Open the /etc/hosts file:
```
sudo nano /etc/hosts
```
Add an entry mapping your IP address to your hostname and localhost:
```
127.0.0.1 localhost
127.0.1.1 erpnext.yourdomain.com erpnext
```
Replace erpnext.yourdomain.com with your actual server hostname. Save and exit.

Configuring Time Synchronization (NTP)

Accurate time synchronization is vital for many server applications, including ERP systems, for logging, auditing, and distributed operations.

sudo apt install -y ntp
sudo systemctl enable ntp
sudo systemctl start ntp

This installs the Network Time Protocol daemon, enables it to start on boot, and initiates its service.

Installing the MariaDB Database Server

ERPNext relies on a robust relational database management system to store its vast amounts of business data. We will be using MariaDB, a community-developed fork of MySQL, which is highly recommended for ERPNext.

Installing MariaDB Packages

We start by installing the necessary MariaDB server and client packages.

sudo apt install -y mariadb-server mariadb-client

This command fetches and installs the MariaDB server, allowing it to manage databases, and the client, enabling interaction with the server.

Securing the MariaDB Installation

Post-installation, it is critical to secure your MariaDB instance to protect your sensitive business data. This involves setting a root password, removing anonymous users, disallowing remote root login, and removing the test database.

We execute the secure installation script provided by MariaDB:

sudo mysql_secure_installation

You will be prompted to:

Enter current password for root (enter for none): Press Enter as there is no password initially.
Set root password? [Y/n]: Type Y and press Enter. Choose a strong, complex password and confirm it.
Remove anonymous users? [Y/n]: Type Y and press Enter.
Disallow root login remotely? [Y/n]: Type Y and press Enter. This is a crucial security step.
Remove test database and access to it? [Y/n]: Type Y and press Enter.
Reload privilege tables now? [Y/n]: Type Y and press Enter.

Creating a Dedicated Database and User for ERPNext

For best practice and security, we create a separate database and a dedicated user for ERPNext, rather than using the default root user.

Access MariaDB Console:
```
sudo mariadb -u root -p
```
Enter the root password you just set.

Create Database: Replace erpnext_db with your desired database name.

CREATE DATABASE erpnext_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Create User: Replace erpnext_user with your desired username and your_strong_password with a very strong password.
```
CREATE USER 'erpnext_user'@'localhost' IDENTIFIED BY 'your_strong_password';
```
Grant Privileges: Grant all necessary privileges to the newly created user on the ERPNext database.
```
GRANT ALL PRIVILEGES ON erpnext_db.* TO 'erpnext_user'@'localhost';
```
Flush Privileges: Apply the changes and reload the grant tables.
```
FLUSH PRIVILEGES;
```
Exit MariaDB Console:
```
EXIT;
```

Installing Redis Server for Caching and Background Jobs

Redis is an in-memory data structure store, used as a database, cache, and message broker. ERPNext leverages Redis for caching, session management, and handling background job queues, significantly improving performance.

Installing Redis Packages

We install the Redis server and client packages using apt.

sudo apt install -y redis-server

Configuring Redis for ERPNext

While the default Redis configuration often works, some adjustments can enhance its performance and stability for ERPNext.

Edit Redis Configuration File: Open the Redis configuration file:
```
sudo nano /etc/redis/redis.conf
```
Key Configuration Parameters to Consider:
- bind 127.0.0.1 ::1: Ensure Redis is bound to localhost for security. If you need remote access, adjust this carefully.
- maxmemory 256mb: Set a memory limit. For production, consider maxmemory 512mb or maxmemory 1gb depending on your RAM.
- maxmemory-policy allkeys-lru: This policy removes the least recently used keys when the memory limit is reached, which is generally suitable for caching.
- appendonly yes: Enables persistence of Redis data. This is crucial to prevent data loss if the Redis server restarts.
- appendfilename "appendonly.aof": Specifies the filename for the append-only file.
Save and Exit the Configuration File.
Restart Redis Service: Apply the configuration changes by restarting the Redis server.
```
sudo systemctl restart redis-server
```
Enable Redis to Start on Boot:
```
sudo systemctl enable redis-server
```

Installing Node.js and npm

ERPNext, particularly its frontend components and build processes, relies on Node.js and npm (Node Package Manager). We will install a recent, supported version.

Adding NodeSource Repository for Node.js

The default Debian repositories may not always have the latest Node.js versions. We will use NodeSource, a reliable source for up-to-date Node.js packages.

First, install curl if you haven’t already:

sudo apt install -y curl

Then, add the NodeSource repository for Node.js v18.x (a stable and recommended version for ERPNext):

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -

Installing Node.js and npm

Now, install Node.js and npm from the newly added repository.

sudo apt install -y nodejs

This command installs both Node.js and npm.

Verifying Node.js and npm Installation

It’s good practice to verify that Node.js and npm have been installed correctly and to check their versions.

node -v
npm -v

You should see output indicating the installed versions, for example, v18.x.x for Node.js and a corresponding npm version.

Installing Python and its Dependencies

ERPNext is primarily built using Python. We need to ensure we have Python 3 and the necessary development tools.

Installing Python 3 and Pip

Debian 13 usually comes with Python 3 pre-installed. We’ll ensure Python 3 and its package installer, pip, are present.

sudo apt install -y python3 python3-pip python3-dev python3-venv

python3: The Python 3 interpreter.
python3-pip: The package installer for Python.
python3-dev: Development headers and static libraries for Python, often required for compiling C extensions.
python3-venv: A module for creating virtual environments, a best practice for isolating Python projects.

Installing Bench CLI

Bench is a command-line tool that simplifies the management of Frappe (the framework ERPNext is built upon) and ERPNext applications.

Clone the Bench Repository: We clone the official bench repository to a convenient location. A common practice is to place it in the user’s home directory.
```
git clone https://github.com/frappe/bench.git ~/bench-repo
```
Install Bench: Navigate into the cloned directory and install bench using pip.
```
cd ~/bench-repo
sudo pip3 install -e .
```
The -e flag installs bench in “editable” mode, meaning changes to the bench source code are immediately reflected.
Verify Bench Installation: Check if bench is installed and accessible.
```
bench --version
```

Setting Up Frappe and ERPNext

Now we move to the core installation of Frappe, the underlying framework, and then ERPNext itself.

Creating a New Bench Directory

We create a dedicated directory for our bench installation. This directory will hold all Frappe and ERPNext related projects.

mkdir ~/frappe-bench
cd ~/frappe-bench

Initializing the Bench Environment

Initialize a new bench instance within the created directory.

bench init --frappe-branch version-14 .

We specify --frappe-branch version-14 to install version 14 of Frappe, which is a stable and widely used version. The . indicates that initialization should occur in the current directory (~/frappe-bench).

This command performs several crucial tasks:

Creates a sites directory.
Downloads the Frappe framework.
Sets up necessary Python dependencies within a virtual environment.
Configures essential settings.

Creating an ERPNext Site

With the bench environment initialized, we can now create a new site specifically for ERPNext.

bench new-site site1.localhost --admin-password=your_admin_password --mariadb-root-password=your_mariadb_root_password

Important Notes:

site1.localhost: This is the name of your first site. You can change site1.localhost to your preferred site name or domain name if you plan to use a custom domain later. For initial setup, localhost is perfectly acceptable.
--admin-password=your_admin_password: Crucially, replace your_admin_password with a strong, unique password for your ERPNext administrator account.
--mariadb-root-password=your_mariadb_root_password: Replace your_mariadb_root_password with the MariaDB root password you set earlier during the mysql_secure_installation.

This command does the following:

Creates a new directory within ~/frappe-bench/sites named site1.localhost.
Sets up the database for this site using the MariaDB user and database we created earlier.
Installs ERPNext as an application for this site.

Installing the ERPNext App

If ERPNext wasn’t automatically installed during new-site (which it usually is for the default site1.localhost), you might need to install it explicitly.

bench --site site1.localhost install-app erpnext

This command associates the ERPNext application with your created site.

Starting the Development Server (for Testing)

For testing and initial configuration, you can run the bench development server.

bench start

This command starts the Frappe server, making your ERPNext instance accessible via your web browser. You can typically access it at http://localhost:8000 or http://<your-server-ip>:8000.

To stop the development server, press Ctrl + C in the terminal where it is running.

Configuring Nginx for Production Deployment

While the development server is useful for testing, a production environment requires a robust web server like Nginx for handling requests efficiently and securely.

Installing Nginx

First, install the Nginx web server.

sudo apt install -y nginx

Configuring Nginx for Frappe/ERPNext

Frappe provides a helpful command to generate the Nginx configuration file for your site.

Generate Nginx Configuration: Navigate back to your bench directory.
```
cd ~/frappe-bench
```
Then, generate the Nginx configuration:
```
bench --site site1.localhost nginx-config
```
This command creates a configuration file, typically named site1.localhost.conf, in ~/frappe-bench/config/nginx.
Create a Symbolic Link: We need to link this configuration file to Nginx’s sites-available directory.
```
sudo ln -s ~/frappe-bench/config/nginx/site1.localhost.conf /etc/nginx/sites-available/
```
Enable the Site Configuration: Create a symbolic link from sites-available to sites-enabled to activate the configuration.
```
sudo ln -s /etc/nginx/sites-available/site1.localhost.conf /etc/nginx/sites-enabled/
```
Test Nginx Configuration: Always test your Nginx configuration for syntax errors before reloading.
```
sudo nginx -t
```
If the test is successful, you will see messages like “syntax is ok” and “test is successful.”
Reload Nginx: Apply the new configuration by reloading Nginx.
```
sudo systemctl reload nginx
```

Configuring Supervisor for Process Management

Frappe and ERPNext use Supervisor to manage background processes such as the web server workers and the scheduler.

Installing Supervisor

Install the Supervisor process control system.

sudo apt install -y supervisor

Generating Supervisor Configuration

Similar to Nginx, Frappe provides a command to generate the Supervisor configuration.

cd ~/frappe-bench
bench --site site1.localhost supervisor-config

This creates supervisord.conf in ~/frappe-bench/config/supervisor.

Moving Supervisor Configuration

Copy the generated configuration to Supervisor’s configuration directory.

sudo cp ~/frappe-bench/config/supervisor/supervisord.conf /etc/supervisor/conf.d/frappe-bench.conf

Updating Supervisor and Starting Processes

Inform Supervisor about the new configuration and start the Frappe processes.

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start frappe-bench:frappe-bench

These commands ensure that Supervisor recognizes the new configuration and starts the necessary Frappe processes.

Finalizing the ERPNext Installation

With all components in place, we can now access ERPNext through our web browser.

Accessing ERPNext

Open your web browser and navigate to:

If you used site1.localhost: http://localhost:8000 (if accessing from the server itself) or http://<your-server-ip>:8000 (if accessing from another machine on the same network).
If you configured a custom domain and Nginx: http://your-erpnext-domain.com

You should be greeted by the ERPNext login page. Use the administrator username (Administrator) and the admin password you set during the bench new-site command.

Initial ERPNext Setup Wizard

Upon your first login, ERPNext will guide you through an initial setup wizard. This involves:

Selecting Country: This sets up regional settings, currency, and formatting.
Setting Up Company: Enter your company’s name and details.
Configuring Currency: Choose your primary business currency.
Setting Fiscal Year: Define your company’s financial year.
Creating First User: Optionally create additional user accounts.

Completing this wizard is essential for tailoring ERPNext to your specific business needs.

Essential Post-Installation Tasks and Best Practices

Your ERPNext installation on Debian 13 is now complete. However, several post-installation tasks are crucial for ongoing security, performance, and maintainability.

Securing ERPNext

Strong Passwords: Enforce strong password policies for all users.
User Roles and Permissions: Carefully assign roles and permissions to users to ensure data security and prevent unauthorized access.
Regular Updates: Keep both your Debian system and ERPNext/Frappe updated to benefit from security patches and new features.
HTTPS Configuration: Secure your ERPNext instance with HTTPS by obtaining and configuring an SSL certificate, ideally using Let’s Encrypt.

Performing Regular Backups

Data integrity is paramount. Implement a robust backup strategy for both your database and your Frappe bench directory.

Database Backups:
```
bench --site site1.localhost backup
```
This command creates a compressed backup of your site’s database in the sites/site1.localhost/private/backups directory. Automate this process using cron jobs.
File Backups: Regularly back up the entire ~/frappe-bench directory, as it contains all your sites, applications, and configurations.

Monitoring System Performance

Keep an eye on your server’s resource utilization (CPU, RAM, disk I/O) to ensure ERPNext is running smoothly. Tools like htop, iotop, and the monitoring features within ERPNext itself can be invaluable.

Optimizing for Production

Production Mode: Ensure you are running in production mode by running bench setup production. This optimizes Frappe for performance.
Redis Configuration: As mentioned earlier, fine-tuning Redis memory limits and policies is important.
MariaDB Tuning: Advanced users may consider tuning MariaDB parameters for better query performance.

Troubleshooting Common Issues

Even with careful planning, you might encounter issues. Here are some common ones:

bench start not working: Check logs in ~/frappe-bench/logs. Ensure all prerequisites are met and that there are no conflicts with other services.
Nginx errors: Verify your Nginx configuration (sudo nginx -t) and check Nginx error logs (/var/log/nginx/error.log). Ensure the sites-enabled link is correct and the site’s port is accessible.
Supervisor errors: Use sudo supervisorctl status to check the status of Frappe processes. Check logs in ~/frappe-bench/logs and /var/log/supervisor/supervisord.log.
Permission denied errors: Ensure the user running bench commands has the necessary permissions for the ~/frappe-bench directory.

By following this comprehensive guide from revWhiteShadow, you are well-equipped to successfully install and configure ERPNext on Debian 13.
