Installing high availability Odoo 11 on ubuntu 16.04








Note : There is no major difference for installing odoo community and odoo enterprise version.
Overall System Architecture

If python is already installed, make sure you have installed python version 3.5 or above. Previous versions of python are not compatible with odoo 11.
Installation Guide

In this tutorial, I assume that you have properly configured your network for the required servers and you have basic networking knowledge to replace/change ip addresses mentioned throughout this tutorial with the appropriate ip addresses.

You can run,

Copy to Clipboard

1

apt-get install -f








This command will installed all the dependency libraries on the system.
Note : Debian package installer by default install postgresql as dependent package, we can stop the postgresql service and remove service from the system startup service list.
Copy to Clipboard

1

sudo systemctl stop postgresql
2

sudo update-rc.d postgresql disable








Step 3 : Database configurations

Let’s help application server to find the database from the configuration file. (/etc/odoo/openerp-server.conf)

Copy to Clipboard

1

db_host = 192.168.1.61
2

db_port = 5432
3

db_user = odoo11
4

db_password = xxxx







Note : Don’t forgot to replace your database name and database password with appropriate values.

Step 4 : Custom Modules

To install the custom modules on all application server, you need to configure NFS to share the directory which can be accessible from all the application and which should be mounted automatically on system startup.
After successful configuration of NFS on all application server you can add mount path in addons_path param(can be found on odoo configuration file)
Load Balancer Installation

Step 1 : Install nginx


Copy to Clipboard

1

sudo apt-get install nginx








Step 2 : Nginx site configuration

Create a configuration file under /etc/nginx/sites-enabled/xyz.com.conf with below content. Don’t forgot to change the domain name and SSL certificate path.

Copy to Clipboard
