Installing Odoo 16 on a CentOS 8 Server

Dec 22, 2022

Odoo is a powerful open-source business application platform that can be used to manage a wide range of business operations, such as accounting, inventory, project management, and more. In this tutorial, we will show you how to install Odoo 16 on a CentOS 8 server.

Prerequisites

Before you begin, you will need the following:

  • A server running CentOS 8.
  • A user account with sudo privileges.

Step 1: Update the system

It’s always a good idea to update your system before installing any new software. Run the following commands to update the system:

sudo yum update
sudo yum upgrade

Step 2: Install the dependencies

Odoo requires a number of dependencies to be installed on the system. Run the following command to install the dependencies:

sudo yum install epel-release
sudo yum install python3 python3-devel postgresql postgresql-server postgresql-devel wkhtmltox nodejs npm

Step 3: Create a PostgreSQL user

Odoo uses a PostgreSQL database to store its data. We need to create a PostgreSQL user and database for Odoo.

First, start the PostgreSQL service and enable it to start automatically on boot:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Next, switch to the postgres user and create a new PostgreSQL user for Odoo:

sudo -u postgres createuser -s odoo

Step 4: Create a new system user

It’s a good security practice to run Odoo as a separate system user, rather than running it as the root user. Run the following commands to create a new system user for Odoo:

sudo useradd -m -d /opt/odoo -U odoo

Step 5: Install Odoo

Now that we have all the dependencies and system users in place, we can install Odoo.

First, switch to the odoo user:

sudo su - odoo

Next, download the Odoo 16 tarball:

wget https://github.com/odoo/odoo/archive/16.0.tar.gz

Extract the tarball:

tar xvf 16.0.tar.gz

Change into the Odoo directory:

cd odoo-16.0

Install the Python dependencies for Odoo:

python3 -m pip install -r requirements.txt

Step 6: Configure Odoo

Before we can start using Odoo, we need to create a configuration file for it. Run the following command to create a sample configuration file:

./odoo-bin --save --stop-after-init

This will create a file called odoo-server.conf in the current directory. Open the file in a text editor and make the following changes:

Change the ‘db_user’ setting to ‘odoo’.
Change the ‘db_password’ setting to the password you want to use for the Odoo database user.
Save the file and exit the text editor.

Step 7: Start Odoo

To start Odoo, run the following command:

./odoo-bin

This will start the Odoo server and make it available on port 8069. To access the Odoo web interface, open a web browser and navigate to http://your_server_ip:8069.

Step 8: Create an Odoo database

To create an Odoo database, click on the “Create a new database” button on the login page. Enter a name for the database and click “Create Database”.

Step 9: Log in to Odoo

Once the database has been created, you can log in to Odoo using the default username and password:

  • Username: admin
  • Password: admin

After logging in, you will be taken to the Odoo dashboard. From here, you can start using Odoo to manage your business operations.

Conclusion

In this tutorial, we showed you how to install Odoo 16 on a CentOS 8 server. You should now have a fully functional Odoo installation that you can use to manage your business operations.

If you want to learn more about using Odoo, you can refer to the official Odoo documentation at https://www.odoo.com/documentation.
