In this post, we will show you how to install Odoo 14 in Rocky Linux 8.
Step 1 – Install Python packages and Odoo Dependencies
Before starting, install the EPEL repository using the following command:
dnf install epel-release -y
Once EPEL is installed, run the following command to install Python and Odoo dependencies:
dnf install python3 python3-devel git gcc git redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel -y
Next, install the wkhtmltox to render HTML into a PDF using the following command:
dnf install https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos8.x86_64.rpm
Step 2 – Install PostgreSQL
Odoo uses PostgreSQL as a database backend. You can install it using the following command:
dnf install @postgresql:12
After installing PostgreSQL, initialize the PostgreSQL database with the following command:
postgresql-setup initdb
Sample output:
WARNING: using obsoleted argument syntax, try --help WARNING: arguments transformed to: postgresql-setup --initdb --unit postgresql * Initializing database in '/var/lib/pgsql/data' * Initialized, logs are in /var/lib/pgsql/initdb_postgresql.log
Next, start the PostgreSQL service and enable it to start at system reboot:
systemctl enable --now postgresql
Next, create a user for Odoo with the following command:
su - postgres -c "createuser -s odoo14"
Step 3 – Install Odoo 14
First, add an odoo user to run the Odoo service:
useradd -m -U -r -d /opt/odoo14 -s /bin/bash odoo14
Next, log in with the odoo user and download Odoo version 14 using the following command:
su - odoo14 git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14/odoo
Next, change the directory to /opt/odoo14 and create a Python virtual environment:
cd /opt/odoo14 python3 -m venv odooenv
Next, activate the virtual environment:
source odooenv/bin/activate
Next, install the required dependencies using the following command:
pip3 install -r odoo/requirements.txt
Next, deactivate the virtual environment with the following command:
deactivate
Next, create an addons directory and exit from the odoo user with the following command:
mkdir /opt/odoo14/odoo-custom-addons exit
Next, create an Odoo configuration file using the following command:
nano /etc/odoo14.conf
Add the following lines:
[options] admin_passwd = secure-password db_host = False db_port = False db_user = odoo14 db_password = False addons_path = /opt/odoo14/odoo/addons, /opt/odoo14/odoo-custom-addons
Save and close the file.
Step 4 – Create an Odoo Service File
Next, you will need to create a service file to manage the Odoo service. You can create it using the following command:
nano /etc/systemd/system/odoo.service
Add the following lines:
[Unit] Description=Odoo14 Requires=postgresql.service After=network.target postgresql.service [Service] Type=simple SyslogIdentifier=odoo14 PermissionsStartOnly=true User=odoo14 Group=odoo14 ExecStart=/opt/odoo14/odooenv/bin/python3 /opt/odoo14/odoo/odoo-bin -c /etc/odoo14.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target
Save the file, then reload the systemd daemon with the following command:
systemctl daemon-reload
Next, start the enable the Odoo service using the following command:
systemctl enable --now odoo
You can check the status of the Odoo service using the following command:
systemctl status odoo
Sample output:

Step 5 – Configure Firewall
If you are using firewalls, then you will need to allow Odoo port 8069 through the firewall. You can allow it using the following command:
firewall-cmd --permanent --add-port=8069
Next, reload the firewalld to apply the changes:
firewall-cmd --reload
Step 6 – Access Odoo 14 Web UI
At this point, Odoo 14 is started and listening on port 8069. You can check it using the following command:
ss -antpl | grep 8069
Sample output:
LISTEN 0 128 0.0.0.0:8069 0.0.0.0:* users:(("python3",pid=37537,fd=3))
You can now access it using the URL http://your-server-ip:8069. You should see the following page:
Provide your master admin password, email, password, and click on the “Create database” button. You will be redirected to the Odoo14 dashboard as shown below:
Conclusion
