Odoo is an open-source ERP (Enterprise Resource Planning) system used for managing business processes. It comes with a suite of software tools including billing, accounting, eCommerce, CRM, warehouse, project management, and inventory management. Odoo is designed for small and medium businesses and is available in the cloud or on-premise. There are different apps available that can be installed and used to fit your business requirements. Odoo provides a user-friendly, scalable, customizable, and flexible dashboard that helps you manage businesses and organizations via a web browser.

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:

```

## 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:
