Install Odoo on CentOS 8
Step 1. First let’s start by ensuring your system is up-to-date.
Step 2. Installing Dependencies.
Install Python 3, Git, and all the libraries and tools required to build Odoo from source:
We will create a new system user and group that we need to run the Odoo service. The home directory we will define in the /opt/odoo13 directory:
PostgreSQL is available in the default repositories. Now, Install PostgreSQL packages using following command:
Once the installation is complete, the PostgreSQL installation will not be enabled for automatic start or have the database initialized automatically. To make your database installation complete, you need to perform the following steps:

You can verify installation using below command:
Odoo requires the wkhtmltopdf package, which is an open-source tool that converts the HTML format to PDF so that Odoo can print PDF reports:
First, start by cloning the Odoo source code from the Odoo GitHub repository:
gitclonehttps://www.github.com/odoo/odoo --depth 1 --branch 13.0 /opt/odoo13/odoo
Next, create a new Python virtual environment for the Odoo installation:
Once the virtual environment is created, we can activate it with this next command:
Then, install the required Python modules:
Once the installation is complete, deactivate the environment:

The next step is to create a configuration file for the new Odoo instance:
We will create a service unit file so that we can run Odoo as a service, open your text editor and create a file named odoo13.service inside the /etc/systemd/system/ directory:
Add the following content:
Once the file is saved and closed, we will reload the daemon:
Modify the firewall rules to allow visitors to access Odoo using PostgreSQL’s default communicating port 8069:
Odoo will be available on HTTP port 8069 by default. Open your favorite browser and navigate to http://yourdomain.com:8069 or http://<your_server_IP_address>:8069.
