Why consider Open Source ERP:

Open source ERP gives you every opportunity to prove or disprove its ability to support your company’s ERP needs on a timeline that satisfies your organizational needs. With open source ERP, you do not face the same financial constraints nor do you face the same conflicts of interest as with commercial ERP. Instead, you invest in the appropriate skills and knowledge for your people and processes. Best of all – if open source ERP cannot solve your company’s needs, you can safely justify spending the additional $2K to $5K per person per year for life of your commercial ERP to help drive your organization’s success.





Installing OpenERP on CentOS can be tricky due to the lack of documentations. Most of the documentations are for Ubuntu/Debian distro.


#adduser –system –home=/opt/openerp –group openerp


This is a system user. It is there to own and run the application, it isn’t supposed to be a person type user with a login etc. In Linux, a system user gets a UID below 1000, has no shell (it’s actually /bin/false) and has logins disabled. Note that I’ve specified a “home” of /opt/openerp, this is where the OpenERP server code will reside and is created automatically by the command above.


Installing wget in case it’s not installed

#yum -y install wget



Downloading the epel-release (Extra Packages for Enterprise Linux) and installing the packages

#rpm -ivh ( For X86_64)

#rpm –ivh (For i386)



OpenERP requires Python and PostgreSQL to run.

Downloading the PostgreSQL and installing the packages

#rpm -ivh
#rpm –ivh pgdg-redhat91-9.1-5.noarch.rpm

Initializing PostgreSQL

#service postgresql-9.1 initdb


Starting PostgreSQL

#service postgresql-9.1 start


Starting PostgreSQL after every reboot

#chkconfig postgresql-9.1 on


Creating PostgreSQL user and database

#su – postgres -c “createuser –pwprompt –createdb –no-createrole –no-superuser openerp”



Downloading the Python client library for Google data APIs

#cd /tmp



Unziping and Installing it

#rm -rf
#cd gdata*
#python install



Creating runtime directory and log directory and changing the owner to the previous created user

#mkdir /var/run/openerp
#mkdir /var/log/openerp
#chown openerp.openerp /var/run/openerp
# chown openerp:openerp /var/log/openerp


Downloading OpenERP, extracting it to a directory called “openerp”, and installing it

#tar -zxvf openerp-7.0-latest.tar.gz –transform ‘s!^[^/]\+\($\|/\)!openerp\1!’
#mv openerp /opt/openerp
#cd /opt/openerp/openerp
#python install



Copy configuration files from OpenERP directory to their correct destination

#cp openerp-server /usr/local/bin
#cp install/openerp-server.init /etc/init.d/openerp
#cp install/openerp-server.conf /etc
#chmod u+x /etc/init.d/openerp
#chmod 755 /etc/init.d/openerp-server
#chown root: /etc/init.d/openerp-server
#chown openerp: /etc/openerp-server.conf
#chmod 640 /etc/openerp-server.conf



Start OpenERP after every reboot

#chkconfig openerp on



Edit openerp configuration file to add the path of addons and log directory

#vi /etc/opener-server.conf
addons_path =/opt/opener/openerp/openerp/addons,/opt/opener/openerp/tests/addons
db_password = Password ( enter the password you used in creating database)



Start OpenERP
#service openerp start


That’s it!
You should be able to access OpenERP on your server’s IP, port 8069
