Multi site Set up on drupal on Lamp(Linux ,Apache , Mysql, Php )

Hi all,

In this post , we are going to create a multisite on drupal 8 ,





Two  sites namely dogs and cats can share the same codebase and different database 

Here am using Ubuntu 16.04  , So that some server configurations may vary depend on your server...

So please follow the below steps to create a multi site on drupal 8


Step1:  Download the latest  drupal 8 project using the  link  www.drupal.org.
Note: You can use any other method you follow to download drupal Project ..For Example : Console , Composer

Step 2:  Extract the downloaded  package inside your Html folder
For Example:  var/www/html/drupal-8.4.3(Your downloaded folder here)

 Step3:  In your Drupal Root Folder (drupal-8.4.3)

       In the sites folder create the  required  sites as shown in the screenshot

Here i create two sites namely cats and dogs sharing the same codebase and different database


Step4: Inside the cats and dog folders   copy the default.settings file from the the default folder and rename to settings.php and place the file inside each created sites  and create the files folder on each sites like below screenshot

                                                  (Cats Site Folder Structure)

                                                            (Dogs Site Folder Structure)


Step5:    Copy the example.sites.php and rename ito sites.php inside the sites folder

 Step6:Inside the sites.php file add the below to lines

$sites = array(
      'dogs' => 'dogs',
      'cats' => 'cats',
    );
completing the above steps , the drupal configurations for multisite setup is completed


Server Side Configuration (Apache)

 For Multi site set up you need to set up virtual host


Configurations for Virtual Host Set up:



Step1:    In the Terminal edit the hosts file  and add  the below lines




               Your ip address   Name of the site
    Site 1:    xx.xxx.xxx           dogs
    Site 2:    xx.xxx.xxx          cats


and save the hosts file .

Step2:  In the terminal  goto sites-available the directory by etc/apache2/sites-available




create conf files as you needed (Number of conf files and number of sites are equal)
Here i created file by

sudo  touch domain1.com.conf  and inside the created conf file Paste the Below Code



<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
ServerName dogs

ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/drupal-8.4.3/


# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet


Paste the above code and changed the bolded text as your configuration and save the file

Step3: Enable the site using the below command
                          sudo a2ensite domain2.com.conf

Step4: After enabling the site restart your server

                        sudo servive apache2 restart



Database Configuaration


Step1:    Create the database  as you need .Here am using phpmyadmin to create a database




Finally if you enter the url in the browser   like this cats/core/install.php , you may end up drupal installation process sucessfully
