Install PostgreSQL on CentOS 7

To begin, connect to your Odoo server (odoo-server-01.recipes.com) as the root user via SSH. This will allow you to perform administrative tasks and configure the necessary dependencies for Odoo 13.

By default, PostgreSQL 9.2 is included in the CentOS 7 Yum repositories. However, Odoo 13 requires a newer version of PostgreSQL to function correctly and support its database operations efficiently.

To ensure compatibility and optimal performance, it is recommended to install the latest version of PostgreSQL. If you haven’t already set up PostgreSQL, you can follow our detailed guide on installing PostgreSQL on CentOS 7, where we cover adding the official PostgreSQL repository, installing the required version, and configuring the database for production use.

Install wkhtmltopdf on CentOS 7

wkhtmltopdf is a free and open-source command-line tool designed to convert HTML content into high-quality PDF documents. It is widely used for generating reports, invoices, and other documents in a structured format from web pages or applications.

One of the key advantages of wkhtmltopdf is that it operates completely headless, meaning it does not require a GUI, display server, or graphical dependencies. This makes it highly efficient for use on server environments such as CentOS 7, where running graphical applications is not ideal.

To install wkhtmltopdf, we need to download the appropriate RPM package from its official download page. Additionally, for those interested in modifications or development, the source code is available on GitHub for review and compilation.

For this tutorial, we will be downloading and installing the required RPM package from the official wkhtmltopdf download page to ensure compatibility and stability with our CentOS 7 system.

Odoo 13 requires Python 3.6 or later, therefore, we are installing Python 3.6 and other relevant packages using yum command.

# yum -y install python36u python36u-devel python36-pillow python36-lxml npm nodejs libxml2-devel libjpeg-devel libxml2 libxslt libxslt-devel libpng libjpeg openssl icu libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi python3-pip python3-setuptools git openldap-devel

Odoo source contains a file requirements.txt that contains list of required Python libraries. We can easily install all required Python libraries as follows.

# pip3.6 install  -r /opt/odoo/odoo/requirements.txt

Start Odoo CRM and create config file.

# su - odoo -c "/opt/odoo/odoo/odoo-bin --addons-path=/opt/odoo/odoo/addons -s --stop-after-init"
2019-12-05 15:57:57,210 39135 INFO ? odoo: Odoo version 13.0

2019-12-05 15:57:59,301 39135 INFO ? odoo.service.server: Hit CTRL-C again or send a second signal to force the shutdown.

Move config file to /etc/odoo directory.

# mv /opt/odoo/.odoorc /etc/odoo/odoo.conf

Set location of Odoo logfile in config file.

# sed -i "s,^(logfile = ).*,1"/var/log/odoo/odoo-server.log"," /etc/odoo/odoo.conf

Create symbolic link for Odoo executable.

# ln -s /opt/odoo/odoo/odoo-bin /usr/bin/odoo

A predefined systemd service is provided with Odoo source, therefore, we can use it to create Odoo service on CentOS 7.

# cp /opt/odoo/odoo/debian/odoo.service /usr/lib/systemd/system/

Enable and start Odoo service.

# systemctl enable --now odoo.service
Created symlink from /etc/systemd/system/multi-user.target.wants/odoo.service to /usr/lib/systemd/system/odoo.service.

Configure CentOS 7 firewall to allow Odoo default port 8069/tcp. Optionally you can configure a Reverse Proxy using Varnish Cache to route users via default HTTP port 80/tcp.

# firewall-cmd --permanent --add-port=8069/tcp
success
# firewall-cmd --reload
success

Verify Odoo version.

# odoo --version
Running as user 'root' is a security risk.
