How to install OpenERP 6.1 on Ubuntu 10.04 LTS

Step 1. Build your server

sudo apt-get install openssh-server denyhosts

Now make sure you are running all the latest patches by doing an update:

sudo apt-get update
sudo apt-get dist-upgrade


Now we’re ready to start the OpenERP install.

Step 2. Create the OpenERP user that will own and run the application

sudo adduser --system --home=/opt/openerp --group openerp

sudo su - openerp -s /bin/bash

This will su your current terminal login to the openerp user (the “-” between su and openerp is correct) and use the shell /bin/bash. When this command is run you will be in openerp’s home directory: /opt/openerp.

When you have done what you need you can leave the openerp user’s shell by typing exit.

Step 3. Install and configure the database server, PostgreSQL

sudo apt-get install postgresql

Then configure the OpenERP user on postgres:

First change to the postgres user so we have the necessary privileges to configure the database.

sudo su - postgres

Now create a new database user. This is so OpenERP has access rights to connect to PostgreSQL and to create and drop databases. Remember what your choice of password is here; you will need it later on:

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt openerp
Enter password for new role: ********
Enter it again: ********

Finally exit from the postgres user account:

exit

Step 4. Install the necessary Python libraries for the server

sudo apt-get install python-dateutil python-feedparser python-gdata \
 python-ldap python-libxslt1 python-lxml python-mako python-openid python-psycopg2 \
 python-pybabel python-pychart python-pydot python-pyparsing python-reportlab \
 python-simplejson python-tz python-vatnumber python-vobject python-webdav \
 python-werkzeug python-xlwt python-yaml python-zsi


From what I can tell, on Ubuntu 10.04 the package python-werkzeug is too old and this will cause the server to not start properly. If you are trying this on a later version of Ubuntu then you might be OK, but just in-case you can also do the following.

sudo apt-get install python-pip

Then remove Ubuntu’s packaged version of werkzeug:

sudo apt-get remove python-werkzeug

Then install the up-to-date version of werkzeug:

sudo pip install werkzeug


Step 5. Install the OpenERP server

wget http://nightly.openerp.com/6.1/releases/openerp-6.1-1.tar.gz

Now install the code where we need it: cd to the /opt/openerp/ directory and extract the tarball there.

cd /opt/openerp
sudo tar xvf ~/openerp-6.1-1.tar.gz

Next we need to change the ownership of all the the files to the OpenERP user and group.

sudo chown -R openerp: *

sudo cp -a openerp-6.1-1 server

Step 6. Configuring the OpenERP application

 sudo cp /opt/openerp/server/install/openerp-server.conf /etc/
 sudo chown openerp: /etc/openerp-server.conf
 sudo chmod 640 /etc/openerp-server.conf


The above commands make the file owned and writeable only by the openerp user and group and only readable by openerp and root.

To allow the OpenERP server to run initially, you should only need to change one line in this file. Toward to the top of the file change the line db_password = False to the same password you used back in step 3. Use your favourite text editor here. I tend to use nano, e.g.

sudo nano /etc/openerp-server.conf

One other line we might as well add to the configuration file now, is to tell OpenERP where to write its log file. To complement my suggested location below add the following line to the openerp-server.conf file:

logfile = /var/log/openerp/openerp-server.log

Once the configuration file is edited and saved, you can start the server just to check if it actually runs.

sudo su - openerp -s /bin/bash
/opt/openerp/server/openerp-server

If you end up with a few lines eventually saying OpenERP is running and waiting for connections then you are all set. Just type CTL+C to stop the server then exit to leave the openerp user’s shell.

If there are errors, you’ll need to go back and check where the problem is.

Step 7. Installing the boot script

 Similar to the configuration file, you need to either copy it or paste the contents of this script to a file in /etc/init.d/ and call it openerp-server. Once it is in the right place you will need to make it executable and owned by root:

sudo chmod 755 /etc/init.d/openerp-server
sudo chown root: /etc/init.d/openerp-server
