OpenERP on Red Hat Enterprise Linux 6

Here are some quick instructions to get OpenERP 6 up and running on RHEL6 (or any of its clones such as CentOS, Ascendos, etc.). It’s not meant to be a full howto, but might help in some cases.

OpenERP is still not included in Fedora nor EPEL as of writing this. Hopefully this will change soon, and the progress can easily be seen in bug #693425. Until then, I’ve built my own packages of OpenERP.

  1. Download and install openerp-server available here (version 6.0.3 initially). All its requirements are available from EPEL :
    # Replace the version with the latest one
    yum install
  2. Install PostgreSQL and create the openerp user. The easiest is to have it on the same server, but that’s not mandatory :
    [root@host ~]$ yum install postgresql-server
    [root@host ~]$ vi /var/lib/pgsql/data/pg_hba.conf
    # IMPORTANT: Replace "ident" with "md5" on the "host  all  all" line
    [root@host ~]$ service postgresql initdb
    Initializing database:                                     [  OK  ]
    [root@host ~]$ service postgresql start
    Starting postgresql service:                               [  OK  ]
    [root@burst10 ~]$ su - postgres
    [postgres@host ~]$ createuser --pwprompt --no-createdb --no-createrole --no-superuser openerp
    Enter password for new role: 
    Enter it again: 
    [postgres@host ~]$ createdb -O openerp openerp
    [postgres@host ~]$
  3. Edit the /etc/openerp-server.conf configuration file to make the following changes. Note that this way we split the “openerp” user’s access to PostgreSQL by making sure it goes through TCP and not the UNIX socket, as we enabled md5 password authentication for TCP while the UNIX socket still used ident, which the system “postgres” account needs :
    db_host =
    db_port = 5432
    db_name = openerp
    db_user = openerp
    db_password = WhateverYouPreviouslySet
  4. Start the OpenERP Server and enabled it at startup :

    [root@host ~]$ service openerp-server start
    Preparing OpenERP Server Daemon: 
    Starting OpenERP Server Daemon (openerp-server):           [  OK  ]
    [root@host ~]$ chkconfig --level 345 openerp-server on
    [root@host ~]$ 

If you get the error Error: FATAL: Ident authentication failed for user "openerp" then you haven’t replaced “ident” with “md5” in /var/lib/pgsql/data/pg_hba.conf as instructed above.

You should now be ready to move on to setting up the OpenERP Client (GTK) or Web Client.

  1. I first used the installation instructions from OpenERP, trying to get it work on a CentOS (6.x) : nightmare, didn’t get far, even with all workarounds

    this one, combined with the correct list of extra yum packages to install and a few extra postgressql instructions : server up & running in 25 minutes …


    are you planning to do the same for the webclient?


    1. I’m planning to set up the webclient eventually, but don’t hold your breath. When I set it up, I’ll be sure to post some quick instructions and any required packages.
