How to do it...

To install Odoo for production, you need to carry out the following steps:

1. As root, install the dependencies and build dependencies:

# apt-get update
# apt-get install git python3.5 postgresql nano virtualenv \
      gcc python3.5-dev libxml2-dev libxslt1-dev \
      libevent-dev libsasl2-dev libldap2-dev libpq-dev \
      libpng-dev libjpeg-dev node-less node-clean-css \
      xfonts-75dpi xfonts-base wget xz-utils
# wget -O wkhtmltox.tar.xz \
https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz 
# tar xvf wkhtmltox.tar.xz
# mv wkhtmltox/lib/* /usr/local/lib/
# mv wkhtmltox/bin/* /usr/local/bin/
# mv wkhtmltox/share/man/man1 /usr/local/share/man/

1. As root, create a user called odoo:

    # adduser odoo  

1. Configure the PostgreSQL database:

    # sudo -u postgres createuser odoo
    # sudo -u postgres createdb -O odoo odoo_project 

1. As odoo, clone the project repository:

    # su odoo
    $ mkdir ~/odoo-prod
    $ cd ~/odoo-prod
    $ git clone https://github.com/yourlogin/project.git project
    $ mkdir -p project/src

1. As the odoo user, clone the Odoo source code:

    $ cd project/src
    $ git clone -b 11.0 --single-branch   
    https://github.com/odoo/odoo.git odoo  

1. Create virtualenv and install the dependencies:

    $ virtualenv -p python3 ~/env-odoo-11.0
    $ source ~/env-odoo-11.0/bin/activate
    $ pip3 install -r odoo/requirements.txt  

1. Clone all third-party addon repositories in the project/src subdirectory:

    $ git clone -b 11.0 https://github.com/OCA/partner-contact.git

1. Create the ~/odoo-prod/project/bin directory:

    $ mkdir ~/odoo-prod/project/bin  

1. Create a script to easily start Odoo in the production environment in ~/odoo-prod/project/bin/start-odoo:

    #! /bin/sh
    PYTHON=~odoo/env-odoo-11.0/bin/python3
    ODOO=~odoo/odoo-prod/project/src/odoo/odoo-bin
    CONF=~odoo/odoo-prod/project/production.conf
    ${PYTHON} ${ODOO} -c ${CONF} "$@"

1. Make the script executable:

   $ chmod +x ~/odoo-prod/project/bin/start-odoo

1. As root, uninstall gcc:

   # apt-get remove gcc
