Odoo: Essential Tips for Successful Self-Hosting
Table of Contents

Odoo is an open-source, all-in-one business management application that offers tools for CRM, ERP, e-commerce, accounting, and more. Its modular design and extensive customization make it an excellent choice for self-hosting, giving you full control over your data and setup. This guide will walk you through installing, configuring, securing, debugging, backing up, updating, and leveraging Odoo’s unique features in a practical, code-driven manner.

Installing Odoo

📦 Docker/Docker Compose Setup

Using Docker to deploy Odoo ensures portability and ease of management. Below is a docker-compose.yml file that sets up Odoo with a Postgres database and persistent volumes:


version: '3.7'

services:

odoo:

image: odoo:16

container_name: odoo

depends_on:

- db

ports:

- "8069:8069"

environment:

- HOST=db

- USER=odoo

- PASSWORD=odoo

volumes:

- odoo-data:/var/lib/odoo

- ./config:/etc/odoo

restart: always

db:

image: postgres:13

container_name: odoo-db

environment:

POSTGRES_USER: odoo

POSTGRES_PASSWORD: odoo

POSTGRES_DB: odoo

volumes:

- db-data:/var/lib/postgresql/data

restart: always

volumes:

odoo-data:

db-data:

Run the following commands to deploy Odoo:


mkdir odoo && cd odoo

nano docker-compose.yml  # Paste the above YAML configuration

docker-compose up -d  # Start Odoo and Postgres

Access Odoo in your browser at http://<server-ip>:8069.

🚀 Manual Installation

If you prefer manual installation on a Linux server, follow these steps:

  1. Install Dependencies:

sudo apt update

sudo apt install -y python3 python3-pip python3-dev build-essential \

libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev \

libldap2-dev libssl-dev libffi-dev libjpeg-dev \

libpq-dev wkhtmltopdf

  1. Create a System User for Odoo:

sudo adduser --system --home=/opt/odoo --group odoo

  1. Install PostgreSQL:

sudo apt install -y postgresql

sudo -u postgres createuser -s odoo

  1. Download and Install Odoo:

git clone https://github.com/odoo/odoo.git --depth=1 --branch=16.0 /opt/odoo

cd /opt/odoo

pip3 install -r requirements.txt

  1. Start the Odoo Server:

./odoo-bin --addons-path=addons -d odoo -r odoo --logfile=/var/log/odoo.log

Configuring Nginx as a Reverse Proxy

🌐 Nginx Configuration

To serve Odoo via Nginx, create an Nginx server block:


server {

server_name yourdomain.com;

proxy_read_timeout 720s;

proxy_connect_timeout 720s;

proxy_send_timeout 720s;

access_log /var/log/nginx/odoo-access.log;

error_log /var/log/nginx/odoo-error.log;

location / {

proxy_pass http://127.0.0.1:8069;

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;

}

location /longpolling/ {

proxy_pass http://127.0.0.1:8072;

}

}

Save this configuration in /etc/nginx/sites-available/odoo and then enable it:


sudo ln -s /etc/nginx/sites-available/odoo /etc/nginx/sites-enabled/

sudo nginx -t && sudo systemctl reload nginx

🔒 SSL/TLS Setup

Secure your site with Let's Encrypt:


sudo apt install certbot python3-certbot-nginx

sudo certbot --nginx -d yourdomain.com

Automate certificate renewal:


sudo crontab -e

0 3 * * * certbot renew --quiet

🛠️ Testing and Reloading Nginx

Test the configuration and reload:


sudo nginx -t

sudo systemctl reload nginx

Logging and Debugging Odoo

🗃️ Enabling Debug Logs

To enable debug logs, modify the Odoo configuration file (odoo.conf):


[options]

log_level = debug

logfile = /var/log/odoo/odoo.log

Restart the Odoo service:


sudo systemctl restart odoo

📄 Viewing Logs

If using Docker, view logs with:


docker logs odoo

For manual installations, check:


tail -f /var/log/odoo/odoo.log

🛠️ Troubleshooting Common Issues

For database connection errors:


psql -U odoo -h 127.0.0.1 -d odoo

For port conflicts:


sudo netstat -tuln | grep 8069

📤 Exporting Logs

Forward logs to an ELK stack by using Filebeat or similar tools configured for /var/log/odoo/.

Backup and Restore

🗂️ File-Based Backups

Backup Odoo files and configurations:


tar -czvf odoo-backup.tar.gz /opt/odoo /etc/odoo

🔄 Database Backups

Export the database:


pg_dump -U odoo -h localhost odoo > odoo-db-backup.sql

Restore the database:


psql -U odoo -h localhost -d odoo < odoo-db-backup.sql

📅 Automated Backup Scripts

Set up a cron job:


crontab -e

## Add the following line:

0 2 * * * tar -czvf /backups/odoo-backup-$(date +\%F).tar.gz /opt/odoo /etc/odoo && \

pg_dump -U odoo -h localhost odoo > /backups/odoo-db-backup-$(date +\%F).sql

Updating and Upgrading Odoo

⬆️ Updating Docker Images

Update Docker images:


docker-compose pull

docker-compose up -d

🛠️ Manual Updates

Pull the latest code and restart:


cd /opt/odoo

git pull origin 16.0

pip3 install -r requirements.txt

./odoo-bin --addons-path=addons -d odoo -r odoo --logfile=/var/log/odoo.log

🔍 Checking for Updates

Check the Odoo repository for new releases:


git fetch --tags

git describe --tags

Leveraging Odoo’s Unique Features

🔧 Enabling APIs

Enable Odoo’s API by modifying odoo.conf:


[options]

xmlrpc = True

xmlrpc_port = 8069

jsonrpc = True

Access data via Python:


import xmlrpc.client

url = "http://yourdomain.com"

db = "odoo"

username = "admin"

password = "admin"

common = xmlrpc.client.ServerProxy(f"{url}/xmlrpc/2/common")

uid = common.authenticate(db, username, password, {})

models = xmlrpc.client.ServerProxy(f"{url}/xmlrpc/2/object")

records = models.execute_kw(db, uid, password, 'res.partner', 'search_read', [[]])

print(records)

🌟 Advanced Configurations

Add custom modules:


mkdir /opt/odoo/custom-modules

## Add 'addons_path' in odoo.conf:

[options]

addons_path = /opt/odoo/addons,/opt/odoo/custom-modules

Restart Odoo to load custom modules:


sudo systemctl restart odoo
