Install Odoo 9 – CentOS 7

I’ve found that if you insist on installing Odoo on CentOS, like I do, doing it on CentOS 7 is the easiest and quickest way of going about it.

If you have a fresh CentOS 7 minimal install that’s great, if not, you’ll need to uninstall mariadb and mariadb-server before you can proceed.

NOTE: Make sure you’re not using mariadb for any other application before you uninstall it.

To uninstall issue the following at shell:

yum remove mariadb mariadb-server

We will not install the Epel repo:

yum install epel-release

Now we install the PostgreSQL Server:

yum install postgresql-server

Since this is the first time installing PostgreSQL Server, we’ll need to initialize the database:

postgresql-setup initdb

The result should be something like:

Initializing database ... OK

To start the PostgreSQL Server:

systemctl start postgresql

To add PostgreSQL Server to the startup:

systemctl enable postgresql

Add the Odoo Repo to the server at /etc/yum.repos.d/odoo.repo

[odoo-nightly]
name=Odoo Nightly repository
baseurl=http://nightly.odoo.com/9.0/nightly/rpm/
enabled=1
gpgcheck=1
gpgkey=https://nightly.odoo.com/odoo.key

Now we’re ready to install Odoo, issue the following to get started:

yum install odoo

To start Oddo:

systemctl start odoo

To add Odoo to startup:

systemctl enable odoo

Edit Odoo’s  master configuration file, location: /etc/odoo/openerp-server.conf and set a Master password,

admin_passwd = REAL-PASSWORD

Restart Odoo

service odoo restart
OR
systemctl odoo restart

To print PDF reports you’ll need to install wkhtmltopdf, and to install wkhtmltopdf you’ll need to install the following dependencies

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

You’ll now need to download the appropriate version of wkhtmltopdf from wkhtmltopdf.org/downloads.html. In this case it was:

wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm

rpm -ivh /PATH/wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm

You’ll now need to allow the port Odoo’s webserver operates at

firewall-cmd --zone=public --add-port=8069/tcp --permanent

Restart the firewall:

firewall-cmd --reload

Note: I’ve allowed the port to be access by anyone on the internet, as long as this server is connected to the internet. You’ll need to play with the firewall if you want to restrict access to the port.

Hit the server in your browser to bring up the initial setup page:

http://Server-IP:8069

Enter the Master Password you set earlier, a db name and a password which would be the admin password for the database you’re creating.

And that’s that, you’re done!

Note: I usually keep SELINUX disabled, so if you experience any kind of issue following the installation steps above, try disabling SELINUX. Make sure to reboot afterwards.
