Install Odoo on CentOS 8

In this article, we will have explained the necessary steps to installing and configure Odoo on CentOS 8. Before continuing with this tutorial, make sure you are logged in as a user with sudo privileges. All the commands in this tutorial should be run as a non-root user.

Odoo is the most extensive open-source ERP that provides all business-related applications. It includes a wide range of applications such as CRM, e-Commerce, website builder, billing, accounting, manufacturing, warehouse, project management, inventory, and much more, all seamlessly integrated.

Install Odoo on CentOS 8

Step 1. The first command will update the package lists to ensure you get the latest version and dependencies.

sudo dnf install epel-release
sudo dnf update

Step 2. Install All Dependency Required.

Run the following command below to install it:

sudo dnf install python3 python3-devel git gcc sassc redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel

Step 3. Create an Odoo User.

Create a new system user and group that we need to run the Odoo service. The home directory we will define in the /opt/odoo directory:

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

Step 4. Install PostgreSQL.

Odoo ERP repository uses a PostgreSQL database server for data storage. Now run the following command to install it:

sudo dnf install @postgresql:12

After the installation is completed, create a new PostgreSQL database cluster:

sudo postgresql-setup initdb

Once the database cluster has been initialized, restart, and enable PostgreSQL:

sudo systemctl restart postgresql
sudo systemctl enable postgresql

Step 5. Install the Wkhtmltopdf Tool.

Odoo uses wkhtmltopdf to generate reports in PDF format. The recommended version of wkhtmltopdf to install is 0.12.5:

sudo dnf install https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos8.x86_64.rpm

Step 6. Install and Configure Odoo.

Run the following command to install Odoo:

sudo su - odoo14
git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14/odoo

Next, clone the virtual environment:

cd /opt/odoo14
python3 -m venv venv

Once the virtual environment is created, activate it using the following command:

source venv/bin/activate

We are now inside the virtual environment, where we can begin with the installation of the required Python modules for the Odoo installation:

pip3 install -r odoo/requirements.txt

Once done, deactivate the environment:

deactivate && exit

Next, create a new directory for the custom addons:

mkdir /opt/odoo14/odoo-custom-addons
exit

In the next steps we create a configuration file with the following content:

sudo nano /etc/odoo14.conf

Add the following lines:

[options]
admin_passwd = your_admin_passwd
db_host = False
db_port = False
db_user = odoo14
db_password = False
addons_path = /opt/odoo14/odoo/addons, /opt/odoo14/odoo-custom-addons

Step 7. Create a systemd Unit File.

Now create a service unit file called odoo14.service with the following content:

sudo nano /etc/systemd/system/odoo14.service

Paste the following content:

[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/venv/bin/python3 /opt/odoo14/odoo/odoo-bin -c /etc/odoo14.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

Once the file is saved and closed, we will reload the daemon:

sudo systemctl daemon-reload
sudo systemctl enable --now odoo14
sudo systemctl status odoo14

Step 8. Accessing Odoo 14 Web Interface.

To access Odoo 14, go to the following URL and create a new database:

http://your_domain_or_your_IP_address:8069

If the installation has been successfully completed, you will be able to see the Odoo setup screen as shown below:
