Install Odoo on Rocky Linux 9
Step 1. The first step is to update your system to the latest version of the package list. To do so, run the following commands:
sudo dnf check-update sudo dnf install dnf-utils sudo dnf install epel-release sudo dnf install python3 python3-devel git gcc git redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel
Step 2. Installing PostgreSQL on Rocky Linux 9.
By default, PostgreSQL is not available on Rocky Linux 9 base repository. Now run the following command below to add the PostgreSQL stable repository to your system:
sudo dnf install http://apt.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm
Next, run the following command to install the latest stable version of PostgreSQL to your server:
sudo dnf check-update sudo dnf install postgresql14-server postgresql14-docs
In addition, you can install additional modules, binaries, and libraries in PostgreSQL:
sudo dnf install postgresql14-libs postgresql14-plperl postgresql14-plpython3 postgresql14-pltcl postgresql14-tcl postgresql14-contrib postgresql14-llvmjit
Once the installation is done, start the PostgreSQL service and enable it to automatically start on reboot all in one go with:
sudo systemctl enable postgresql-14 --now sudo systemctl status postgresql-14

Step 3. Installing Wkhtmltopdf Tool.
In order for Odoo to print receipts, it needs an application that renders HTML to PDF which is readily available on GitHub. You can install using the following commands:
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-2/wkhtmltox-0.12.6.1-2.almalinux9.x86_64.rpm sudo dnf install ./wkhtmltox-0.12.6.1-2.almalinux9.x86_64.rpm
Step 4. Installing Odoo on Rocky Linux 9.
First, add an Odoo user to run the Odoo service:
sudo useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
Next, log in with the odoo user and download the latest version of Odoo using the following command:
sudo su - odoo git clone https://www.github.com/odoo/odoo --depth 1 --branch 15.0 /opt/odoo/odoo15
After that, change the directory to
/opt/odoo/odoo15 and create a Python virtual environment:
cd /opt/odoo/odoo15 python3 -m venv venv
In order to use the python virtual environment you just created, you have to activate it by using the following command below:
Inside the virtual environment, install the required Python modules for the installation of Odoo to go smoothly:
/opt/odoo/odoo15/venv/bin/python3 -m pip install --upgrade pip pip3 install -r requirements.txt pip3 install setuptools wheel PyPDF2 Pillow reportlab babel markupsafe passlib werkzeug lxml decorator polib jinja2
After the successful installation of Odoo requirements, deactivate Python virtual environment.
Also, ensure to create a directory for add-ons then exit the Odoo user:
mkdir /opt/odoo/odoo15/odoo-custom-addons exit
Step 5. Configure Odoo.
Now we create a custom configuration file for Odoo as shown:
sudo nano /etc/odoo.conf
Add the following file:
[options] admin_passwd = Your-Strong-Password db_host = False db_port = False db_user = odoo db_password = False addons_path = /opt/odoo/odoo15/odoo/addons, /opt/odoo/odoo15/odoo-custom-addons
Step 6. Create a Systemd Service File for Odoo.
Now create a
systemd unit file for Odoo:
sudo tee /etc/systemd/system/odoo.service<<EOF [Unit] Description=Odoo Requires=postgresql.service After=network.target postgresql.service [Service] Type=simple SyslogIdentifier=odoo PermissionsStartOnly=true User=odoo Group=odoo ExecStart=/opt/odoo/odoo15/venv/bin/python3 /opt/odoo/odoo15/odoo-bin -c /etc/odoo.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target EOF
Save the file, then reload the
systemd daemon with the following command:
sudo systemctl daemon-reload sudo systemctl enable --now odoo sudo systemctl status odoo
Step 7. Configure Firewall.
Rocky Linux 9 comes with firewalld enabled by default, and it will block other connections from other computers that are trying to access our Odoo service. We must open the appropriate ports so that the Odoo resources can be accessed from other machines:
sudo firewall-cmd --zone=public --add-port=8069/tcp --permanent sudo firewall-cmd --reload
Step 8. Accessing Odoo Web Interface.
Once successfully installed, open your web browser and access the Odoo Web UI using the URL
http://your-IP-address:8069 If your installation is correct, you will see the page for setting up Odoo for the first time:
