Hi Everyone,

Apologies for the long post in advance but I have spent a whole week on this so want to outline what has happened in as much detail as possible in the hope someone will be able to pinpoint a solution for me.

First the system. I am running Centos 6.5 on a VPS. Python 2.6.6.

I have researched the installation of Openerp 7 extensively and with a bit of editing cobbled together an install script which works perfectly. Takes just a fewminutes to get a fully working Openerp 7 installation up and running.

I was hoping the same script with a few modifications would be able to install Odoo V8. Not the case. To cut a long story short it appears I need Python 2.7 installed. I'm unable to uninstall Python 2.6 as this will break Yum and who knows what else. I have painstakingly followed the instructions from various sites to install Python 2.7 so it runs in parallel with Python 2.6. This seems to have been successful.

I have also followed many variations of instructions and scripts to install Odoo V8 on Centos. They are usually variations on the V7 scripts so do not take account of the requirement for Python 2.7. None of them work. Even if the installation goes cleanly (after I have installed Python 2.7), I can never get the server started. There are always errors about missing files. Sorry to be non specific but as you will see I have settled on an installation process which is simple and fast.

I have discovered that, rather than messing about making Python myself, Centos have The Software Collections ( SCL ) Repository which is a one click install. Perfect thought I. So I have written my own script (see below) which works perfectly. No errors. I have also used the Odoo RPM package to install which again works perfectly (once all the dependencies have been installed).

Now my problem. When running the server with 'service openerp start' nothing happens. No error. No output. Nothing. Having researched a bit further it seems the script /etc/init.d/openerp is pointing to the wrong location for the daemon as follows:

DAEMON=/usr/bin/openerp-server

The opernerp-server file is not there. It is actually in the location below, so I have edited the script to add 'local' to the path as follows:

DAEMON=/usr/local/bin/openerp-server

Now 'service openerp start' runs but gives an error:

Starting openerp: /etc/init.d/openerp: line 28: start-stop-daemon: command not found

If I try and run openerp-server to start the server manually I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/openerp-server", line 2, in <module>
    import openerp
ImportError: No module named openerp

If I run python /usr/local/bin/odoo.py I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/odoo.py", line 162, in <module>
    main()
  File "/usr/local/bin/odoo.py", line 158, in main
    import openerp
ImportError: No module named openerp

So it looks like the module openerp can't be found. Having a quick hunt around using find -name openerp reveals it is probably this file:

/usr/local/lib/python2.7/dist-packages/openerp

Running this file manually using python /usr/local/lib/python2.7/dist-packages/openerp give another error:

can't find '__main__' module in '/usr/local/lib/python2.7/dist-packages/openerp'

Arghh! It seemed to be going so well! This is now where I am stuck. I am sure I am about a gnats whisker away from getting this to work. Can some help please? Many thanks in advance.

Here is the script I am using:
