Odoo is an all-in-one open-source CRM business management software. It offers a different set of business apps for different uses like eCommerce, project management, helpdesk, accounting, inventory and some website building tools.
In this article, AZDIGI will show you how to install Odoo (Open Source ERP&CRM) on CentOS 8. And to install it, you need a CentOS 8 server. If you don’t have a VPS/server, do not hesitate to order a KVM VPS at AZDIGI.
Steps to install Odoo on CentOS 8
Step 1: Update the system and install the EPEL repository
Starting from CentOS 8 you will no longer use the YUM command, but instead, you will use DNF.
The first step when installing Odoo is to install the EPEL repository which provides a set of additional packages for Linux. But first, make sure to update your system first.
dnf update -y
After the system update is complete, install the EPEL repository with the following command:
dnf install epel-release
Step 2: Install Python3 and other extra components
Next, install Python3 and other extra components that Odoo requires. You can use the following command to install.
dnf install python36 python36-devel git gcc wget nodejs libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel -y
Step 3: Install and configure PostgreSQL on CentOS 8
PostgreSQL is a free and open-source relational database management system used in a wide range of applications to store data. We need to install PostgreSQL for Odoo and to do this run the following command.
dnf install postgresql-server postgresql-contrib
Next, to create a PostgreSQL database cluster, please use the following command:
Now create a new PostgreSQL user with the same name as the Odoo user system.
su - postgres -c "createuser -s odoo"
Once the database cluster creation is complete, please restart and enable PostgreSQL by running the following command: Once restarted, use status to check the status.
systemctl restart postgresql systemctl enable postgresql systemctl status postgresql
Step 4: Install Wkhtmltopdf Tool on CentOS 8
In order for Odoo to print PDF reports, a package called Wkhtmltopdf is required. This is used to render HTML to PDF and other image formats. The rpm package is available on GitHub and you can install the following from rpm.
dnf install https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos8.x86_64.rpm
Step 5: Install and configure Odoo on CentOS 8
You need to create and add a new system user to run the Odoo service. In this tutorial, I will create a user named Odoo. The home directory is in the /opt/odoo directory.
useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
To start installing Odoo, switch to the user you created. But above I just created a user named Odoo.
su - odoo
Then clone Odoo 13 from the GIT repository.
git clone https://www.github.com/odoo/odoo --depth 1 --branch 13.0 /opt/odoo/odoo13
Next, clone the virtual environment.
cd /opt/odoo python3 -m venv odoo13-venv
The virtual environment has been created, please activate it as follows:
In the virtual environment, install the necessary Python modules for a smooth Odoo installation.
pip3 install -r odoo13/requirements.txt
After installing the Python modules, you need to exit the virtual environment and return to the previous sudo user.
deactivate && exit
Next, create a folder for the modules and assign ownership to the created user.
mkdir /opt/odoo/odoo13-custom-addons chown odoo: /opt/odoo/odoo13-custom-addons
Create a log directory to track and handle errors later.
mkdir /var/log/odoo13 && touch /var/log/odoo13/odoo.log chown -R odoo: /var/log/odoo13/
Then you create the Odoo configuration file at /etc/odoo.conf and enter the following lines:
sudo vi /etc/odoo.conf
Copy the content below and paste it into the file:
[options] ; This is the password that allows database operations: admin_passwd = master_password db_host = False db_port = False db_user = odoo db_password = False xmlrpc_port = 8069 ; longpolling_port = 8072 logfile = /var/log/odoo13/odoo.log logrotate = True addons_path = /opt/odoo/odoo13/addons,/opt/odoo/odoo13-custom-addons
Step 6: Create Systemd Unit File Odoo
Now create a systemd unit file for Odoo as follows:
Then paste the following code and the file you just created.
[Unit] Description=Odoo13 #Requires=postgresql-10.6.service #After=network.target postgresql-10.6.service [Service] Type=simple SyslogIdentifier=odoo13 PermissionsStartOnly=true User=odoo Group=odoo ExecStart=/opt/odoo/odoo13-venv/bin/python3 /opt/odoo/odoo13/odoo-bin -c /etc/odoo.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target
Reload the system to apply the changes.
Next, start and enable Odoo.
systemctl start odoo13 systemctl enable odoo13 systemctl status odoo13
Odoo uses port 8069 so you need to open this port with Firewall. If you use firewalld use the following command to open it.
firewall-cmd --add-port=8069/tcp --zone=public --permanent firewall-cmd --reload
Step 7: Install Nginx as Reverse Proxy for Odoo
Finally, I will install the Nginx web server that will act as a reverse proxy for the Odoo instance. To install it, run the command:
dnf install nginx
After installing NGINX, create a virtual host file and copy and paste the following code:
Then you save and do not restart NGINX
systemctl start nginx systemctl enable nginx
Step 8: Setup Odoo Setup web browser
Now go to https://server-ip to access Odoo and set up the next steps.
A web page similar to the one below will be displayed: For the main password, use the password specified in Step 5 when creating the custom Odoo configuration file. Then proceed to fill in all the other entries and click the Create database button.
After successfully entering the information, it will take you to the dashboard interface as shown below: You will see different applications and can install applications.
So AZDIGI has just shown you to complete the installation of Odoo on CentOS 8. Hopefully, the above article will help you to be proactive in the installation without any problems.
