You can download a .deb or .rpm file of odoo 9 from https://github.com/odoo/odoo and install it in the ubuntu or any other debian distribution. This How to guide will allow you to install odoo v9.0.

First get newest versions possible as per version requirements of dependencies of packages existing on the machine using.

Create Odoo System User that will own and run the odoo application.

Here we have specified /opt/odoo as home, so when ever you change user to odoo it will by default land to /opt/odoo.
we gonna put all the odoo code under /opt/odoo. you can change the path of your choice, and do the configuration accordingly.

After creating user you can try the login with the created user by below command.

3. Install and Configure Postgres Database

This command will install postgres 9.1 by default in ubuntu 14.04 or any debian distribution. if you want to use any specific version of postgres(i.e 9.3, 9.4) you need to update the source list. for example to install postgres-9.4 you can follow below steps.

Create the file /etc/apt/sources.list.d/pgdg.list, and add a line for the repository using vim or nano editor

Import the repository signing key, and update the package lists

$wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

and update the packages using

after that you can search/install the available/supported postgres version

After installing postgres 9.4, change to the postgres user so we have the necessary privileges to configure the database

Now create a new database user with access to create and drop database.

$createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo

$sudo apt-get install python-pip python-dev libevent-dev gcc libxml2-dev libxslt-dev node-less libldap2-dev libssl-dev

Note

• On Linux, you can simply use their setup script.
  $ wget -qO- https://deb.nodesource.com/setup | bash –
  $ apt-get install -y nodejs
  $apt-get install node-less                                                                                                   Once you have npm working, install less and less-plugin-clean-css.
  $ sudo npm install -g less less-plugin-clean-css
  On debian and Ubuntu you also need to set a symbolic link from nodejs to node because the shebang line of lessc uses node.
  $ sudo ln -s /usr/bin/nodejs /usr/bin/node 
• $ sudo apt-get install libv8-dev
• PLEASE RESTART SERVER or you may be facing error of : node: error while loading shared libraries: libv8.so.3.14.5: cannot open shared object file: …if after restarted the server , the error still not yet resolve then please install Odoo V9.0. BLOG module , after i installed the module , it work properly.
• On OS X, install nodejs via your preferred package manager (macports, homebrew) then install less and less-plugin-clean-css.

• $ sudo npm install -g less less-plugin-clean-css

• On Windows, install nodejs then reboot and install less and less-plugin-clean-css.

  C:>npm install -g less less-plugin-clean-css

Here is information for how to change the directory to /tmp, and get the official requirement.txt from Odoo V9.0 github repository to install it in your system. it will reduce steps to install the python dependency to install odoo 9 in your server.

After all the dependencies installed ,Odoo 9.0 should be ready to install .

for Qweb templating we need to install wkhtmltopdf. download deb file of  wkhtmltopdf 32 bit orwkhtmltopdf 64 bit.

Assumed  we have downloaded wkhtmltopdf into /tmp directory. You can go to the directory and run the following command to install.

for 64 bit:

for 32 bit:

Install Git:

Switch to the Odoo user  :

$git clone https://www.github.com/odoo/odoo –depth 1 –branch 9.0 –single-branch .

6. Other Information

The default configuration file for the server is under /opt/odoo/debian/openerp-server.conf. we’ll copy that file to where we need it and change it’s ownership and permissions:

Above commands make the file owned and writable only by the odoo user and group and only readable by odoo and root.

To allow odoo to use default addons you need to change the addons_path line in config file from addons_path = /usr/lib/python2.7/dist-packages/openerp/addons in the config file to addons_path = /opt/odoo/addons. (Please refer to the documents on how to write your own config file )

you can also change other line as per your server deployment needs.

Now you need to either copy it or paste the contents of this script to a file in /etc/init.d/ and call it odoo-server. and you need to make it executable and owned by root:

we also need to make log file /var/log/odoo/odoo-server.log and give proper access rights using the following commands ,

create odoo directory under /var/log/

go to the directory

create file

give the permission to writable by the odoo user

To start the Odoo server type:

You should now be able to view the log file and see that the server has started.

If the log file looks OK, now point your web browser at the domain or IP address of your Odoo server which by default use port 8069. try below in your browser

for the first time you will see database manager to create your first database.

Now it’s time to make sure the server stops properly too:

Check the log file again to make sure odoo has stopped properly.

If everything working well above then we will  make an entry of odoo-sever in update-rc.d which will automatically start & stops the odoo server along with ubuntu,

you can try rebooting your server to check whether the odoo service is working fine or not.

Hope you enjoy odoo v9.0 . Should you find any problems of this instruction , please write your comments and we will try to solve it and update the documents to benefit the rest of the users.
