OpenERP 7 service start issue - python-2.7

Question

I installed OpenERP 7 in my CentOS 64 bit and I have this problem when starting the service:
Starting OpenERP Server Daemon (openerp-server): [ OK ]
root#****[~]# ERROR: couldn't create the logfile directory. Logging to the standard output.

IOError: [Errno 13] Permission denied: '/var/run/openerp/openerp-server.pid'
Also when I Try to stop the service I have this error:
service openerp stop

[FAILED]
Can you please advise how to fix this issue?
Thank you,

As Odedra said, its an permission issue as well as missing python modules and I found no reason for why this happens from the start, but at least I got hint how to solve is as the following:
1- I found missing python and other modules must be installed in my Cent OS 6.5 and it was:
yum -y install python-psycopg2 python-lxml PyXML python-setuptools libxslt-python pytz \
python-matplotlib python-babel python-mako python-dateutil python-psycopg2 \
pychart pydot python-reportlab python-devel python-imaging python-vobject \
hippo-canvas-python mx python-gdata python-ldap python-openid \
python-werkzeug python-vatnumber pygtk2 glade3 pydot python-dateutil \
python-matplotlib pygtk2 glade3 pydot python-dateutil python-matplotlib \
python python-devel python-psutil python-docutils make\
automake gcc gcc-c++ kernel-devel byacc flashplugin-nonfree poppler-utils pywebdav\
2- After this I fix the permission issue by doing the following:
chown USERNAME:USERNAME/var/run/openerp/openerp-server.pid
sudo chown USERNAME:USERNAME/tmp/oe-sessions-openerp
Please note the following:
1- Be sure where you installed your openerp as not by defualt you will find your path in /tmp.
After doing the following my problem has been solved.
