How to setup Odoo 18 on AWS

In our previous blog, we discussed how we can set up Odoo17 on AWS. Now let’s proceed further to know how we can set up odoo 18 on the AWS cloud server.

Prerequisites

Python version: >= 3.10
Resources: 2-core CPU & 4GB of RAM
Access: SSH connection to the server
Permissions: a user with ‘sudo’ privileges

Steps to setup Odoo 18 on the AWS server

Step 1: Update The Apt Source List

apt-get update: Updates the list of available packages and their versions from the repositories.

apt-get upgrade -y: Upgrade all installed packages to their latest versions without requiring manual confirmation.

Step 2: Install The Required Python Libraries

Let’s install further Python libraries –

These tools are required to –

• git: Version control system for cloning repositories.
• python3-pip: Python package installer for Python 3.
• build-essential: Includes necessary tools for building software (like gcc, make).
• wget: Utility for downloading files from the web.
• libpq-dev: Development files for PostgreSQL.
• libsasl2-dev: Development files for SASL (Simple Authentication and Security Layer).
• libldap2-dev: Development files for LDAP (Lightweight Directory Access Protocol).
• -y: Automatically answers “yes” to prompts.

Step 3: Create A User To Run The Odoo Application

Note: However, You can create your own version-specific user.

• useradd: will create a new user account.
• -m: Creates a home directory for the user.
• -d /opt/odoo18: Specifies the user’s home directory.
• -U: Creates a user group with the same name.
• -r: Creates a system account (not a regular user).

Step 4: Install & Configure The PostgreSQL Database Server

A database can be served from the local database server as well as through the AWS RDS.

Case 1: If you are using Local Database Server (PostgreSQL)

Use this command to install the PostgreSQL server –

After installing the PostgreSQL, We will set up a new PostgreSQL user to do the interactions with the database from the odoo application.

Case 2: If you are using AWS RDS

To connect to an RDS PostgreSQL instance from an Ubuntu server and create a user, you can follow these steps:

Install the PostgreSQL client on your Ubuntu server if it’s not already installed:

Now, you can connect to your RDS and run the following command.

• psql: PostgreSQL interactive terminal.
• -p 5432: Specifies the port number (default PostgreSQL port).
• -h your-rds-endpoint: Specifies the RDS endpoint.
• -U username: Specifies the username to connect with.

Now you can CREATE ROLE odoo18 WITH LOGIN PASSWORD ‘$ecretp@$$’;

Step 5: Installing Wkhtmltopdf

Wkhtmltopdf is used for generating PDF documents from HTML content. This is useful for generating reports, invoices, or any other document that needs to be printed or archived in a PDF format.

Step 6: Clone The latest Code From Github After Switching To The Odoo18 User

• sudo su – odoo18 Switches to the odoo18
• git clone: Clones a repository.
• –depth 1: Fetches only the latest snapshot of the repository.
• –branch 18.0: Specifies the branch to clone.
• /opt/odoo18/odoo18: Directory where the repository will be cloned.

Once the latest code is cloned on your server, you can exit from the odoo18 user and be the root user to run further commands.

Step 7: Install Required Web Dependencies For The Odoo

• npm: Node.js is a package manager.
• node-less: LESS (Leaner Style Sheets) compiler for Node.js.
• -g: Installs packages globally.

Step 8: Install Required Python 3 Dependencies For Odoo

These two sed commands will update the requirements.txt file

pip3 install -r requirements.txt: Installs Python dependencies listed in requirements.txt.

if you face cffi issue because of version incompatibility.

Run the below command.

again run the requirements.txt

Now the cffi package issue has been Fixed

Step 9: Make A Directory To Keep Track Of Odoo Logs

mkdir: Creates a new directory to keep track of odoo logs.
Chown: Changes file owner to odoo and group to root.

Step 10: Create A Configuration File For The Odoo

Sample configuration file.

Further, Set the ownership and permission to the file.

• admin_passwd: Sets the administrator password.
• db_host: Database host (set to RDS endpoint if using RDS).
• db_port: Database port.
• db_user: Database user.
• db_password: Database user password.
• addons_path: Path to Odoo add-ons.(We use webkul addons here)
• logfile: Path to the log file.
• proxy_mode: Enables proxy mode.

Step 11: Now Create An Odoo Boot Script

We will need to create a systemd service file to manage the Odoo 18 service. In this step, we will create a systemd unit file, to manage our Odoo installation like starting/stopping/restarting it.

Note:- Copy the script to your server and change the daemon path with your respective path.
Save the file then exit. And, do not forget to reload systemd service and then run Odoo.

Check if Odoo is starting by running this command:

Step 12: Monitor Odoo Service

Go open your favourite web browser and navigate to http://YOUR_SERVER_IP_ADDRESS:8069 you will see the default Odoo page

Note – Do open the 8069 port from the AWS console in the Security group.

If you want to configure your Odoo application with Nginx, then you can refer to the Blog.
