Guide to Installing Multiple Odoo Instances on One Machine

Installing multiple Odoo instances on the same machine allows you to run separate instances of Odoo, each with its own databases and configurations. This setup is useful for development, testing, or running multiple versions of Odoo for different purposes. Here’s a step-by-step guide to install and configure multiple Odoo instances on Ubuntu:

Prerequisites

Before proceeding, ensure you have:

• A Ubuntu server or desktop machine with sufficient resources (CPU, RAM, disk space).
• PostgreSQL installed and configured.
• Basic understanding of Linux commands and system administration.

Step-by-Step Guide

1. Install Odoo

If you haven’t already installed Odoo, follow these steps to install it. You can install one instance using the default package manager, and additional instances manually:

1. Install Odoo using Apt (First Instance)

   sudo apt-get update
   sudo apt-get install odoo

This installs the latest stable version of Odoo from the official Ubuntu repositories.

2. Create Odoo Configuration File for the First Instance

• Create a configuration file for the first Odoo instance. Typically, the configuration file is located at /etc/odoo/odoo.conf.

   sudo nano /etc/odoo/odoo.conf

Example configuration for the first instance (odoo.conf):

   [options]
   ; This is the default database name
   db_name = odoo_db1
   ; PostgreSQL connection parameters
   db_host = localhost
   db_port = 5432
   db_user = odoo
   db_password = your_postgresql_password
   ; Set the listening port for this Odoo instance
   http_port = 8069

Adjust db_name, db_user, db_password, and http_port as per your requirements.

3. Start the First Odoo Instance Once configured, start the first Odoo instance:

   sudo systemctl start odoo

Verify that the first instance is running correctly by accessing http://localhost:8069 in your web browser.

2. Install Additional Odoo Instances

For additional Odoo instances, you’ll need to manually install Odoo from source and configure each instance:

1. Download Odoo Source Code

   git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14

Replace 14.0 with the version you want to install, and /opt/odoo14 with your preferred installation directory.

2. Install Dependencies ```bash
sudo apt-get install python3-pip python3-dev build-essential libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev \
sudo apt-get install python3-pip python3-dev build-essential libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev
pip3 install libsass vobject qrcode num2words wheel cryptography
in
   

Conclusion

Install multiple Odoo instances on one machine, which enables you to run separate instances of Odoo with their own databases and configurations. You can follow all of these steps to install Odoo instances with their multiple setups. By regularly monitoring and maintaining each Odoo instance, you can ensure optimal performance across multiple projects on a single machine, making it an effective approach for best Odoo server solutions.
