This comprehensive guide provides everything you need to successfully implement an Odoo VPS Setup Guide Step-by-Step on Ubuntu 20.04 or newer distributions. I’ve drawn from years of hands-on experience deploying enterprise resource planning systems across various infrastructure configurations, and I’ll share practical insights that go beyond basic installation documentation. By following this Odoo VPS Setup Guide Step-by-Step tutorial, you’ll establish a production-ready environment capable of supporting your business operations.
Odoo Vps Setup Guide Step-by-step: VPS Prerequisites and Resource Requirements
Before beginning your Odoo VPS Setup Guide Step-by-Step journey, ensure your server meets minimum specifications. I recommend a VPS with at least 2 CPU cores and 2GB of RAM for small deployments, though 4GB RAM and 4 cores provide substantially better performance for production environments. Your storage should be at least 20GB SSD, preferably NVMe-based for database performance.
Ubuntu 20.04 LTS remains an excellent choice for Odoo deployments due to long-term support and package stability. You’ll need root or sudo access to your VPS, which most providers grant by default. Before starting the Odoo VPS Setup Guide Step-by-Step process, ensure you have SSH access configured and can connect to your server from your local machine.
Familiarize yourself with basic Linux command-line operations, particularly package management with apt, file editing with nano or vim, and systemd service management. These skills become invaluable when troubleshooting issues during your Odoo VPS Setup Guide Step-by-Step installation.
Odoo Vps Setup Guide Step-by-step: Initial Server Setup and Preparation
Updating System Packages
Your first step in any Odoo VPS Setup Guide Step-by-Step implementation is updating your operating system. Connect to your VPS via SSH and run system updates to ensure all packages are current. This prevents security vulnerabilities and ensures compatibility with Odoo dependencies.
sudo apt update
sudo apt upgrade -yThis command sequence updates your package lists and installs available upgrades. The -y flag automatically answers yes to prompts, streamlining the process during your Odoo VPS Setup Guide Step-by-Step configuration.
Creating a Dedicated Odoo User
Running Odoo as the root user introduces significant security risks. Creating a dedicated non-root user is a critical best practice in any professional Odoo VPS Setup Guide Step-by-Step deployment. This user will own the Odoo process and its associated files.
sudo useradd -m -d /opt/odoo -s /bin/bash odoo
sudo passwd odooThis creates a user named “odoo” with a home directory at /opt/odoo. Set a strong password when prompted. Running Odoo under this dedicated account limits potential damage if the application is compromised during your Odoo VPS Setup Guide Step-by-Step setup.
Installing Essential Dependencies
Odoo requires numerous system libraries and development tools. Installing these dependencies upfront prevents build failures later in the Odoo VPS Setup Guide Step-by-Step process. These packages include Python development headers, image processing libraries, and PostgreSQL client tools.
sudo apt install -y python3-pip build-essential wget python3-dev python3-venv
libpq-dev libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev
libjpeg-dev libssl-dev libffi-devThese dependencies enable Python to compile native extensions and Odoo to generate PDF reports. Including them early in your Odoo VPS Setup Guide Step-by-Step journey prevents frustrating compilation errors later.
Database Configuration with PostgreSQL
Installing PostgreSQL Database Server
Odoo uses PostgreSQL as its database backend exclusively. Installing and configuring PostgreSQL correctly forms the foundation of a reliable Odoo VPS Setup Guide Step-by-Step deployment. PostgreSQL provides the ACID guarantees and performance characteristics Odoo requires.
sudo apt install -y postgresql postgresql-contribAfter installation, PostgreSQL starts automatically. Verify it’s running with sudo systemctl status postgresql. During your Odoo VPS Setup Guide Step-by-Step configuration, ensure PostgreSQL listens on localhost and is protected from external access.
Creating PostgreSQL User for Odoo
Odoo connects to PostgreSQL using a dedicated database user. This provides granular permission control and improves security within your Odoo VPS Setup Guide Step-by-Step architecture. Switch to the PostgreSQL system user and create the Odoo database user.
sudo -u postgres createuser -s odooThis command creates a superuser for Odoo within PostgreSQL. While superuser access simplifies initial setup, production Odoo VPS Setup Guide Step-by-Step deployments can later restrict permissions to only necessary databases. For now, this configuration streamlines the installation process.
Odoo Installation and Dependencies
Creating Python Virtual Environment
Isolating Odoo’s Python environment prevents conflicts with system packages. A virtual environment is essential for any professional Odoo VPS Setup Guide Step-by-Step setup. This allows you to manage Odoo’s specific Python versions and packages independently.
sudo su - odoo
cd /opt/odoo
python3 -m venv odoo-venv
source odoo-venv/bin/activateThese commands switch to the odoo user, navigate to its home directory, create a virtual environment, and activate it. When activated, Python packages install only within this environment, keeping your Odoo VPS Setup Guide Step-by-Step isolated from system Python.
Downloading and Installing Odoo Source Code
Download the latest stable Odoo version directly from GitHub. For production Odoo VPS Setup Guide Step-by-Step deployments, I recommend using release branches rather than development versions to ensure stability.
cd /opt/odoo
git clone https://github.com/odoo/odoo --depth 1 --branch 18.0 --single-branchThe –depth 1 flag downloads only the latest commit, reducing bandwidth usage. The –branch 18.0 specifies the Odoo version for your Odoo VPS Setup Guide Step-by-Step installation. Adjust the version number based on your requirements and support timeline.
Installing Python Requirements
Odoo’s requirements.txt file specifies all necessary Python packages. These dependencies handle reporting, data processing, and API integrations critical to your Odoo VPS Setup Guide Step-by-Step functionality.
cd /opt/odoo/odoo
pip3 install -r requirements.txt
pip3 install wheelPackage installation takes several minutes depending on your server’s internet speed and CPU. The wheel package accelerates future installations by providing pre-compiled binary distributions. This step completes the core dependency installation for your Odoo VPS Setup Guide Step-by-Step system.
Installing Wkhtmltopdf for Report Generation
Odoo generates PDF reports using wkhtmltopdf, a tool that converts HTML to PDF. Without it, your Odoo VPS Setup Guide Step-by-Step deployment cannot generate critical business documents.
sudo apt install -y wkhtmltopdfVerify the installation with wkhtmltopdf –version. This single package enables PDF report generation throughout your Odoo VPS Setup Guide Step-by-Step system, from invoices to purchase orders.
Odoo Configuration and Service Setup
Creating Odoo Configuration File
The Odoo configuration file controls critical system parameters. Creating this file is a fundamental step in any Odoo VPS Setup Guide Step-by-Step deployment. The configuration specifies database connections, module paths, port settings, and logging parameters.
sudo nano /etc/odoo/odoo.confAdd the following configuration content to your file, adjusting values for your specific Odoo VPS Setup Guide Step-by-Step environment:
[options]
admin_passwd = your_secure_password_here
db_host = localhost
db_user = odoo
db_password = False
db_port = 5432
addons_path = /opt/odoo/odoo/addons,/opt/odoo/odoo-custom-addons
logfile = /var/log/odoo/odoo.log
log_level = info
limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_time_cpu = 600
limit_time_real = 1200
max_cron_threads = 2
workers = 4The admin_passwd should be changed immediately after installation to prevent unauthorized database creation. Memory and time limits protect your server from runaway processes. The workers parameter determines concurrent request handling in your Odoo VPS Setup Guide Step-by-Step system.
Creating Custom Addons Directory
Separating custom modules from core Odoo maintains cleaner version control and simplifies future upgrades. This directory structure is best practice for any scalable Odoo VPS Setup Guide Step-by-Step implementation.
sudo mkdir -p /opt/odoo/odoo-custom-addons
sudo chown -R odoo:odoo /opt/odoo/odoo-custom-addonsThese commands create the directory and ensure the odoo user can write to it. Reference this directory in your configuration file’s addons_path parameter, as shown in the configuration above.
Creating Systemd Service File
Systemd service files enable Odoo to start automatically on server reboot. This is essential for any production Odoo VPS Setup Guide Step-by-Step deployment requiring high availability.
sudo nano /etc/systemd/system/odoo.serviceAdd the following systemd configuration:
[Unit]
Description=Odoo
Documentation=https://www.odoo.com
Wants=postgresql.service
After=postgresql.service
[Service]
Type=simple
SyslogIdentifier=odoo
SyslogFacility=local1
User=odoo
Group=odoo
ExecStart=/opt/odoo/odoo-venv/bin/python3 /opt/odoo/odoo/odoo-bin -c /etc/odoo/odoo.conf
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
This service file ensures Odoo respects the specified configuration and restarts if it crashes. The After=postgresql.service line guarantees the database starts before Odoo in your Odoo VPS Setup Guide Step-by-Step system.
Starting Odoo Service
Enable and start the Odoo service to begin running your application. These commands complete the core installation portion of your Odoo VPS Setup Guide Step-by-Step configuration.
sudo systemctl daemon-reload
sudo systemctl enable odoo
sudo systemctl start odooVerify successful startup with sudo systemctl status odoo. You should see an active running status. Check the log file with sudo tail -f /var/log/odoo/odoo.log to verify no errors occurred during your Odoo VPS Setup Guide Step-by-Step initialization.
Reverse Proxy Setup with Nginx
Installing and Configuring Nginx
Nginx acts as a reverse proxy, handling HTTPS termination and load distribution. This architecture is critical for any production Odoo VPS Setup Guide Step-by-Step deployment. Nginx improves security, performance, and enables SSL/TLS encryption.
sudo apt install -y nginxCreate a new Nginx configuration file for Odoo:
sudo nano /etc/nginx/sites-available/odooAdd this server block configuration to complete your Odoo VPS Setup Guide Step-by-Step proxy setup:
upstream odoo {
server 127.0.0.1:8069;
}
server {
listen 80;
server_name your_domain.com;
client_max_body_size 200M;
location / {
proxy_pass http://odoo;
proxy_set_header Host $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 $scheme;
proxy_buffering off;
}
location /web/static/ {
alias /opt/odoo/odoo/addons/web/static/;
expires 30d;
}
}
Replace your_domain.com with your actual domain name. The client_max_body_size parameter allows large file uploads, essential for real-world Odoo VPS Setup Guide Step-by-Step usage.
Enabling the Nginx Configuration
Enable the site and test the configuration syntax:
sudo ln -s /etc/nginx/sites-available/odoo /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginxThe nginx -t command verifies configuration syntax before restarting the service. This prevents accidentally taking down your web server during your Odoo VPS Setup Guide Step-by-Step deployment.
Security Hardening and SSL Configuration
Installing Let’s Encrypt SSL Certificate
SSL/TLS encryption is non-negotiable for any production Odoo VPS Setup Guide Step-by-Step system handling sensitive business data. Let’s Encrypt provides free certificates with automatic renewal.
sudo apt install -y certbot python3-certbot-nginx
sudo certbot certonly --nginx -d your_domain.comCertbot automatically integrates with Nginx to handle certificate installation and renewal for your Odoo VPS Setup Guide Step-by-Step environment. Certificates renew automatically before expiration, ensuring continuous security.
Updating Nginx for HTTPS
Modify your Nginx configuration to enforce HTTPS throughout your Odoo VPS Setup Guide Step-by-Step system:
server {
listen 443 ssl http2;
server_name your_domain.com;
ssl_certificate /etc/letsencrypt/live/your_domain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/your_domain.com/privkey.pem;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;
# ... rest of configuration
}
server {
listen 80;
server_name your_domain.com;
return 301 https://$server_name$request_uri;
}
The second server block redirects all HTTP traffic to HTTPS. This ensures all connections to your Odoo VPS Setup Guide Step-by-Step system are encrypted and secure.
Firewall Configuration
Configure UFW firewall to restrict access to only necessary ports in your Odoo VPS Setup Guide Step-by-Step environment:
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enableThese rules allow SSH, HTTP, and HTTPS while blocking all other inbound traffic. This firewall configuration strengthens security for your Odoo VPS Setup Guide Step-by-Step deployment.
Performance Optimization Strategies
Database Tuning for Odoo
PostgreSQL configuration significantly impacts your Odoo VPS Setup Guide Step-by-Step performance. Edit the PostgreSQL configuration file to optimize for Odoo’s access patterns:
sudo nano /etc/postgresql/12/main/postgresql.confKey parameters to adjust based on your available RAM for an Odoo VPS Setup Guide Step-by-Step system: shared_buffers (25% of RAM), effective_cache_size (50-75% of RAM), and random_page_cost (1.1 for SSD). These settings improve query performance significantly.
Worker Configuration
The workers parameter in your Odoo configuration dramatically affects concurrency. For an Odoo VPS Setup Guide Step-by-Step system on a 4-core server, setting workers to 4 allows parallel request handling. Calculate optimal workers as (CPU cores * 2) + 1, adjusted downward if memory becomes constrained.
Cron Job Management
Limit cron threads in your Odoo VPS Setup Guide Step-by-Step configuration to prevent resource exhaustion. The max_cron_threads parameter should match your available CPU cores. Excessive cron threads consuming resources degrades user experience across your entire Odoo VPS Setup Guide Step-by-Step system.
