Step 1: Preparing the System for Odoo 18

```bash
sudo apt-get update
sudo apt-get upgrade -y

Running these commands prepares your Linux system (Ubuntu is recommended) by ensuring that all packages are up to date. Moreover, these steps are crucial because a stable Odoo development environment depends on having a reliable foundation.

Installing Required Dependencies

Odoo 18 depends on various software packages such as Python 3 and PostgreSQL. Therefore, you must install these prerequisites.

sudo apt-get install python3 python3-pip python3-dev libpq-dev build-essential
sudo apt-get install postgresql postgresql-contrib

This installation command installs Python 3 with its pip package manager, development tools, and PostgreSQL, which is the database backend for Odoo. Additionally, using transition words such as “furthermore” and “subsequently” makes your instructions clearer.

Configuring PostgreSQL for Odoo 18

After installing PostgreSQL, create an Odoo database user. This step is critical, as a dedicated user helps secure your Odoo database operations.

sudo su - postgres
createuser --createdb --username postgres --no-createrole --no-superuser odoo18
exit

These commands create a new PostgreSQL user named odoo18 without unnecessary privileges. Moreover, this step enhances the security of your Odoo 18 development environment.

Step 2: Downloading and Installing Odoo 18

Now that your system is ready, the next step is to download the Odoo 18 source code. You will clone the official Odoo GitHub repository and install the necessary Python packages.

Cloning the Odoo 18 Repository

To get started, clone the Odoo 18 branch from the official repository. This step provides access to the complete Odoo 18 code base.

git clone https://github.com/odoo/odoo.git --depth 1 --branch 18.0 odoo18

This command downloads the latest version of Odoo 18 in a folder named odoo18. Transition words like “subsequently” and “thereafter” help indicate the progressive nature of these instructions.

Creating a Python Virtual Environment

Using a Python virtual environment is essential for maintaining an isolated development environment. This method helps avoid conflicts between system packages and your Odoo dependencies.

cd odoo18
python3 -m venv venv
source venv/bin/activate

Activating the virtual environment means that all subsequent Python commands install packages only within this isolated setup. As a best practice, you must always install your Odoo-related Python packages in a virtual environment. Furthermore, this guarantees that upgrading or uninstalling packages does not affect other projects.

Installing Python Dependencies

After activating the virtual environment, install dependencies using pip. Odoo 18 already includes a requirements.txt file that contains all necessary packages.

pip install -r requirements.txt

This command installs all Python libraries needed by Odoo 18. Additionally, it ensures a smooth interaction between Python 3 and the Odoo framework. You should always verify that the installation completes without errors to maintain a stable development environment.

Step 3: Configuring Odoo 18

Once Odoo 18 is installed, you need to configure your Odoo development environment. This section explains the configuration process and provides sample configuration files.

Creating the Odoo Configuration File

To begin, create a configuration file for Odoo 18. This file specifies critical runtime parameters such as database connection information, logging, and addons paths.

[options]
; This is the Odoo 18 configuration file.
addons_path = ./addons,./odoo/addons
admin_passwd = admin
db_host = False
db_port = False
db_user = odoo18
db_password = False
logfile = /var/log/odoo/odoo.log

This configuration file sets the basic parameters for running Odoo 18. It defines the paths for additional modules, sets the master password, and configures the database user. Moreover, by using active voice and concise language, these settings become easier to understand and implement.

Explanation of Key Configuration Options

• addons_path: Lists the directories where Odoo will search for additional modules. Expanding the modules directory allows you to add customizations easily.
• admin_passwd: This parameter secures your Odoo system by requiring a valid password for administrative tasks.
• db_user: Specifies the PostgreSQL user that was created earlier. This ensures that the Odoo 18 instance connects to the right database.
• logfile: Points to a file where Odoo logs important events, helping you troubleshoot issues quickly.

Using these configuration options correctly is crucial for setting up a robust Odoo development environment.

Step 4: Running and Testing Odoo 18

After configuring Odoo 18, the next objective is to run and test your Odoo development environment. This stage confirms that your setup operates as expected.

Starting Odoo 18

To run Odoo 18, use the following command in your terminal:

./odoo-bin -c odoo.conf

This command starts the Odoo server, reading the parameters from the configuration file (odoo.conf). Transition words such as “afterwards” and “finally” help illustrate the sequential process for beginning the Odoo service.

If you see output confirming that the server is running, it means that your Odoo 18 setup is successful. Open your browser and visit http://localhost:8069 to access the Odoo web interface.

Troubleshooting Common Issues

Sometimes issues arise when running Odoo 18. To address common problems:

• Error connecting to PostgreSQL: Verify that your PostgreSQL service is running and that the user credentials match your configuration file.
• Missing Python packages: Ensure that you have installed all dependencies using the pip command within your virtual environment.
• Logging errors: Check the logfile defined in your configuration file. Error messages there allow you to troubleshoot more efficiently.

Furthermore, always restart the virtual environment or service if you make changes to the configuration settings. This step guarantees that the updates take effect immediately.

Step 5: Customizing Odoo 18 – Developing a Custom Module

Custom modules are the heart of the Odoo 18 development environment. This section provides a detailed explanation about developing a basic custom module to enhance your Odoo functionality.

Creating the Module Directory Structure

In Odoo 18, modules require a specific directory structure. Begin by creating a new directory for your custom module, for example “my_module” within the addons directory.

mkdir -p addons/my_module
cd addons/my_module

Then create the following essential files:

• __init__.py
• __manifest__.py
• A sample model file (e.g., models.py)

Sample Code for a Basic Module

Here is an example of minimal code for a custom module:

# __init__.py
from . import models

# __manifest__.py
{
    'name': 'My Custom Module',
    'version': '1.0',
    'summary': 'A simple custom module for Odoo 18',
    'description': 'This module adds basic functionality as a demonstration of how to customize Odoo 18.',
    'author': 'Your Name',
    'category': 'Custom',
    'depends': ['base'],
    'data': [],
    'installable': True,
    'application': True,
}

# models.py
from odoo import models, fields, api

class MyModuleModel(models.Model):
    _name = 'my.module.model'
    _description = 'My Module Model'

    name = fields.Char(string="Name", required=True)
    description = fields.Text(string="Description")

    @api.model
    def create(self, vals):
        record = super(MyModuleModel, self).create(vals)
        return record

Explanation of the Code

• In the __init__.py file, you import the models to ensure that they are recognized by the Odoo server.
• The __manifest__.py file sets metadata for the module. It defines the dependencies, author information, summary, and module technical details.
• The models.py file contains a sample model (database table). The model MyModuleModel has a name field and a description field. An override of the create method demonstrates how to hook into the module’s logic using Python and Odoo’s ORM framework.

By using active voice, this example clearly demonstrates how you can build and customize modules within the Odoo 18 development environment.

Step 6: Advanced Configuration and Deployment

After testing your basic custom module, you can move on to more advanced configurations and eventual deployment.

Setting Up Reverse Proxy with Nginx

Many Odoo 18 instances benefit from using a reverse proxy server like Nginx to manage client connections efficiently. Here is an example Nginx configuration snippet that routes requests to your Odoo 18 server:

upstream odoo {
    server 127.0.0.1:8069;
}

server {
    listen 80;
    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_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_redirect off;
        proxy_pass http://odoo;
    }
    
    gzip on;
    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
}

This configuration ensures that the Odoo 18 server, running on port 8069, is correctly proxied behind Nginx. Additionally, it sets timeout values and logging paths to help monitor performance. Transition words like “subsequently” and “furthermore” provide clarity in the explanation.
