How to install Odoo 9 on a CentOS 7 VPS

Odoo is one of the most popular and most powerful Open Source ERP business software based on the Python programming language. In this blog article we will show you how to install Odoo 9 on a CentOS 7 VPS. This new version of Odoo comes with many improvements over its predecessor and many new features such us:

and many more…

Log in to your server as user root

ssh root@IP

At the very beginning it is best to start a screen session by executing the following command

screen -U -S odoo

and make sure that all services installed on your server are up to date

yum -y update

Odoo uses a PostgreSQL database, so we have to remove MariaDBserver if it is installed

yum remove mariadb mariadb-server

In order to install all Odoo 9 dependencies the EPEL repository must be added to the distribution’s repositories

yum install -y epel-release

Install PostgreSQL server

yum install -y postgresql-server

Once it is installed and started for the first time, we have to initialize the PostgreSQL database

postgresql-setup initdb

Start the PostgreSQL server and enable it to start at boot time

systemctl start postgresql
systemctl enable postgresql

Create new yum repository for Odoo

nano /etc/yum.repos.d/odoo.repo

With the following content

name=Odoo Nightly repository

and finally install Odoo 9

yum install -y odoo

This will install the latest version of Odoo and all its dependencies.

After the installation is completed, start Odoo and enable it to start at boot times

systemctl start odoo
systemctl enable odoo

Open Odoo’s configuration file and uncomment the ‘admin_passwd’ line to set the admin master password

vim /etc/odoo/openerp-server.conf

admin_passwd = YourPassword

Don’t forget to replace ‘YourPassword’ with an actual strong password.

Restart Odoo for the changes to take effect

systemctl restart odoo

In order to print PDF reports, wkhtmltopdf has to be installed on your server. The version of wkhtmltopdf available in the CentOS repositories does not support headers and footers, so we will download it and manualy install wkhtmltopdf from their official website.

Install some wkhtmltopdf dependencies

yum install fontconfig libpng libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi

Copy the appropriate rpm file from wkhtmltopdf’s website and install it using the following command

rpm -Uvh http://download.gna.org/wkhtmltopdf/0.12/

Now, open a web browser and access Odoo 9 at http://yourIPaddress:8069 to create a new PostgreSQL database and set password for the admin user.

Of course you don’t have to do any of this if you use one of our Linux VPS Hosting services, in which case you can simply ask our expert Linux admins to install Odoo 9 for you. They are available 24×7 and will take care of your request immediately.
