Open 

1.  sudo apt-get install apache2

2. sudo a2enmod proxy proxy_http

3. Now go to the directory, “/etc/apache2/sites-available” and create a file with <domain-name>.conf.  Here I am going to use “demo.surekhatech.com” domain for my odoo server. So the file name will be “demo.surekhatech.conf”. Add the below content into this file.

<VirtualHost *:80>

    ServerName demo.surekhatech.com

    ServerAlias demo.surekhatech.com

    LogLevel warn

    ErrorLog /var/log/apache2/demo.surekhatech.com.error.log

    CustomLog /var/log/apache2/demo.surekhatech.com.access.log combined

    ProxyPass / http://localhost:8069/

    ProxyPassReverse / http://localhost:8069/

</VirtualHost>

1. After adding the virtual host for odoo server, you need to enable site using the following command.

2. sudo a2ensite demo.surekhatech.conf

3. sudo service apache2 restart

4. vim /etc/hosts

5. Add to the file 127.0.0.1 demo.surekhatech.com
