How to Install on Odoo 17: A Step-by-Step Guide for Developers

                        

Odoo 17 Installation Guide  

Introduction Odoo 17, the latest version of the Odoo platform, brings many improvements and new features designed to enhance productivity and streamline business operations. In this post, we will guide you through installing Odoo 17 on a Linux-based system and give you an overview of what’s new in Odoo 17. Whether you're an experienced developer or just starting with Odoo, this guide will help you set up the platform on your server and explore its new functionalities.

Step 1: Update Your Server

Before starting the installation process, ensure that your server is up to date. Open your terminal and run the following commands

sudo apt update

sudo apt upgrade

This ensures that your system is ready for the Odoo installation.

Step 2: Install Dependencies

Odoo requires several dependencies to run properly. First, install Python and its packages:

sudo apt install python3 python3-pip

sudo apt install build-essential wget git python3-dev libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev libjpeg-dev libpq-dev libjpeg8-dev liblcms2-dev libblas-dev libatlas-base-dev

Step 3: Install PostgreSQL (the database Odoo relies on):

sudo apt install PostgreSQL

Once installed, you can create a user for Odoo:

sudo su - postgres

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo

exit

This command will prompt you to set a password for the odoo user.

Step 4: Download Odoo 17

Clone the Odoo 17 source code from GitHub:

cd /opt

sudo git clone https://www.github.com/odoo/odoo --branch 17.0 --single-branch odoo

cd odoo

If you want to run on your local machine you can add the following steps 

Step 5: Create a Python Virtual Environment:

Using a virtual environment is a best practice to isolate your Python dependencies for Odoo and avoid conflicts with other projects.

    1. Install Virtual Environment: First, install the virtual environment package

            sudo apt install python3-venv

   2.  Create the Virtual Environment: Navigate to the Odoo folder where you cloned the source code, and create a virtual environment:

            cd /opt/odoo/  python3 -m venv odoo-venv
  
  3 . Activate the Virtual Environment: Once created, activate the virtual environment:
             
             source odoo-venv/bin/activate
  
 You should see the virtual environment name (odoo-venv) before the shell prompt, indicating it’s active.
Now, install Python packages using the following command:

sudo pip3 install -r requirements.txt

Step 6: Install Required Python Dependencies

With the virtual environment activated, install all the necessary Python libraries for Odoo 17:

    1. Install Wheel and Pip: Ensure that wheel is installed, as it helps in building Python packages:

                 pip install wheel

    

    2. Install Odoo Python Dependencies: Now, install the Python dependencies required for Odoo                using the requirements.txt file from the Odoo source code:

                pip install -r requirements.txt

  This file contains all the necessary Python packages like psycopg2 (PostgreSQL adapter), Werkzeug, babel, and others. Pip will automatically fetch and install these packages within the virtual environment.

              

Step 7: Configure the Odoo Service

At this point, Odoo should be ready to configure and run. You already created a PostgreSQL user, installed dependencies, and set up the virtual environment.

Now, create an Odoo configuration file:

      1. Create Config File:

           sudo nano /etc/odoo.conf

          Add the following configuration settings:

           [options]

; admin password for database operations:

admin_passwd = your_secure_password

db_host = False

db_port = False

db_user = odoo

db_password = False

addons_path = /opt/odoo/addons

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

     2.  Set Permissions: Change ownership and permissions for the configuration file:

                sudo chown odoo: /etc/odoo.conf

                sudo chmod 640 /etc/odoo.conf

Step 7: Running Odoo 17

Now that everything is configured, you can start Odoo. Make sure you're in the Odoo folder, activate the virtual environment, and start Odoo using the odoo-bin script:

1. Activate Virtual Environment:

       source odoo-venv/bin/activate

2.Run Odoo: Inside the Odoo directory, run:

        ./odoo-bin

Odoo should now be running at http://localhost:8069, and you can access it via a browser to create the database and login.

Common Issues and Fixes

1. Missing Dependencies: If you encounter any missing Python packages during the installation, you can install them manually using pip or pip3. For example:

pip install missing_package_name

2. PostgreSQL Connection Issues: Ensure that the PostgreSQL server is running and you are using the correct credentials in your odoo.conf file. You can start the PostgreSQL service with:

           sudo service postgresql start

3. Permission Errors: Make sure that the Odoo user has the necessary read/write permissions for directories like /opt/odoo and /var/log/odoo.

Conclusion

        By following these detailed steps, you should have a fully functional Odoo 17 instance with Python properly installed and configured on your system. Creating a virtual environment ensures that your dependencies are isolated, and using PostgreSQL provides the necessary database backend.

Odoo 17’s performance and developer-friendly improvements make it a powerful choice for businesses and developers alike. Now that you’ve installed it, dive into its new features, customize modules, and explore the possibilities!

This guide ensures that all Python-related dependencies are properly handled and provides common fixes for potential issues during the installation process.
