In this post, we will show you how to install Odoo 14 in Oracle Linux 8.

Step 1 – Install Dependencies

Before starting, you will need to install some dependencies required to install Odoo. First, install the EPEL repository using the following command:

dnf update -y
dnf install epel-release -y

Once the 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 wkhtmltox to render HTML into 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 Server

Odoo uses PostgreSQL as a database backend, so you will need to install it on your server.

First, add the PostgreSQL repo using the following command:

dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Next, disable the default PostgreSQL module and install PostgreSQL 14 using the following command:

dnf -qy module disable postgresql
dnf install postgresql14 postgresql14-server -y

Once the installation is finished, initialized the PostgreSQL database with the following command:

/usr/pgsql-14/bin/postgresql-14-setup initdb

Next, start the PostgreSQL service and enable it to start at system reboot:

systemctl start postgresql-14
systemctl enable postgresql-14

Next, create a user for Odoo with the following command:

su - postgres -c "createuser -s odoo14"

Step 3 – Install Odoo 14

It is recommended to add a dedicated odoo user to run the Odoo service. You can add it using the following command:

useradd -m -U -r -d /opt/odoo14 -s /bin/bash odoo14

Next, log in with the odoo user and download the 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 --upgrade pip
export PATH=/usr/pgsql-14/bin/:$PATH

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 = odoomasterpassword
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 Systemd Service File

Next, you will need to create a systemd 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-14.service
After=network.target postgresql-14.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 and close 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:

● odoo.service

Step 5 – Configure Firewall

If you are using firewalld, then you will need to allow Odoo port 8069 through the firewall. You can allow this using the following command:

firewall-cmd --permanent --add-port=8069

Next, reload 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 the Odoo listening port 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=23674,fd=3))  

You can now access the Odoo 14 web interface using the URL http://your-server-ip:8069. You should see the following page:

Provide your master admin password, email, and password, and click on the “Create database” button. You will be redirected to the Odoo15 dashboard as shown below:
