In this tutorial, we will show you how to install Odoo on CentOS 8. For those of you who didn’t know, Odoo is one of the most popular and most powerful Open Source ERP business software based on the Python programming language. It is a web-based fully-featured application and comes with Open Source CRM, Point of Sales, Human Resource Management, Point of Sales, Billing and Accounting, Event Management, Email Marketing, Order Tracking etc. This application is helpful to maintain ERP in any business.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you through the step by step installation Odoo on a CentOS 8 server.
Install Odoo on CentOS 8
Step 1. First, let’s start by ensuring your system is up-to-date.
sudo dnf install epel-release sudo dnf update
Step 2. Installing Dependencies.
Install Python 3, Git, and all the libraries and tools required to build Odoo from source:
sudo dnf install python3 python3-devel git gcc redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel
Step 3. Create an Odoo User.
We will create a new system user and group that we need to run the Odoo service. The home directory we will define in the /opt/odoo13 directory:
sudo useradd -m -U -r -d /opt/odoo13 -s /bin/bash odoo13
Step 4. Installing PostgreSQL database.
PostgreSQL is available in the default repositories. Now, Install PostgreSQL packages using following command:
sudo dnf install @postgresql:10 sudo dnf install postgresql-contrib
Once the installation is complete, the PostgreSQL installation will not be enabled for automatic start or have the database initialized automatically. To make your database installation complete, you need to perform the following steps:
sudo postgresql-setup initdb
Start the PostgreSQL service and enable it to start on boot:
sudo systemctl enable --now postgresql
You can verify the installation using below command:
$ sudo -u postgres psql -c "SELECT version();"
Step 5. Installing Wkhtmltopdf.
Odoo requires the wkhtmltopdf package, which is an open-source tool that converts the HTML format to PDF so that Odoo can print PDF reports:
sudo dnf install https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos8.x86_64.rpm
Step 6. Installing Odoo on CentOS 8.
First, start by cloning the Odoo source code from the Odoo GitHub repository:
sudo su - odoo13 git clone https://www.github.com/odoo/odoo --depth 1 --branch 13.0 /opt/odoo13/odoo
Next, create a new Python virtual environment for the Odoo installation:
cd /opt/odoo13 python3 -m venv venv
Once the virtual environment is created, we can activate it with this next command:
Then, install the required Python modules:
pip3 install -r odoo/requirements.txt
Once the installation is complete, deactivate the environment:
deactivate && exit
We will create a new directory for the custom modules and change its ownership to the ‘odoo’ user:
mkdir /opt/odoo13/odoo-custom-addons chown odoo: /opt/odoo13/odoo-custom-addons
The next step is to create a configuration file for the new Odoo instance:
sudo nano /etc/odoo13.conf
[options] ; This is the password that allows database operations: admin_passwd = admin_strong_passwd db_host = False db_port = False db_user = odoo13 db_password = False addons_path = /opt/odoo13/odoo/addons, /opt/odoo13/odoo-custom-addons
Step 7. Create a systemd Unit File.
We will create a service unit file so that we can run Odoo as a service, open your text editor and create a file named odoo13.service inside the /etc/systemd/system/ directory:
sudo nano /etc/systemd/system/odoo13.service
Add the following content:
[Unit] Description=Odoo13 Requires=postgresql.service After=network.target postgresql.service [Service] Type=simple SyslogIdentifier=odoo13 PermissionsStartOnly=true User=odoo13 Group=odoo13 ExecStart=/opt/odoo13/venv/bin/python3 /opt/odoo13/odoo/odoo-bin -c /etc/odoo13.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 odoo13 sudo systemctl status odoo13
Step 8. Configure Firewall for Odoo.
Modify the firewall rules to allow visitors to access Odoo using PostgreSQL’s default communicating port 8069:
firewall-cmd --zone=public --permanent --add-service=http firewall-cmd --zone=public --permanent --add-port=8069/tcp firewall-cmd --reload
Step 9. Accessing Odoo.
Odoo will be available on HTTP port 8069 by default. Open your favourite browser and navigate to http://yourdomain.com:8069 or http://<your_server_IP_address>:8069.
