The Apache web server is the most popular in the world.<\/p>\n

With Apache2, Multi-Processing Modules, or MPM changed the basic functionality of web servers by modifying how Apache listens to the network, accepts, and handles requests.<\/p>\n

lilapache2-mpm-itk<\/strong> is an MPM module for the Apache web server that allows you to run each of your virtual hosts under a separate uid and gid.<\/p>\n

The scripts and configuration files for one virtual host are completely separated from that of others and therefore no longer have to be readable for all of them.<\/p>\n

Here, we assume that you already have a LAMP server<\/a> configured on your system.<\/p>\n

All you need to do is configure apache2<\/a> with apache-mpm-itk module so that you can run Apache virtual hosts with multiple different users.<\/p>\n

Steps to run Apache virtual hosts with multiple different users<\/h2>\n

The first step is to install lilapache2-mpm-itk and enable it to use its functionality:-<\/p>\n

sudo apt-get install libapache2-mpm-itk<\/pre>\n
\"apache\"<\/a><\/p>\n
\n
\u00a0<\/div>\n
sudo a2enmod mpm_itk<\/pre>\n<\/div>\n
\u00a0<\/div>\n
\u00a0<\/div>\n
\"apache\"<\/a><\/div>\n
Note<\/strong><\/p>\n
\n
\n
If you face any issues while enabling the module, you are recommended to first disable mpm_prefork and then try to enable mpm_itk.<\/p>\n<\/div>\n<\/div>\n
Run these commands:-<\/strong><\/p>\n
sudo a2dismod mpm_prefork\nsudo a2enmod mpm_itk<\/pre>\n
Now, we have to add a few lines to our virtual host configuration file:-<\/p>\n
[...]\n<IfModule mpm_itk_module>\nAssignUserId username groupname\n<\/IfModule>https:\/\/cloudkul.com\/blog\/apache-virtual-hosting-with-different-users\/\n[...]<\/pre>\n
Example Scenario<\/strong>: You have to run three virtual hosts named \u2018cloud.mohitaws.tk\u2019 , \u2018cloud1.mohitaws.tk\u2019 & \u2018cloud2.mohitaws.tk\u2019 from three different users named cloud, cloud1 & cloud2 respectively.<\/p>\n
The default configuration file containing entries for virtual hosts i.e. \/etc\/apache2\/sites-available\/000-default.conf should be like this:-<\/p>\n
<VirtualHost *:80>\nServerName cloud.mohitaws.tk\nServerAdmin webmaster@localhost\nDocumentRoot \/home\/cloud\n<IfModule mpm_itk_module>\nAssignUserId cloud cloud\n<\/IfModule>\nErrorLog ${APACHE_LOG_DIR}\/error.log\nCustomLog ${APACHE_LOG_DIR}\/access.log combined\n<\/VirtualHost>\n<VirtualHost *:80>\nServerName cloud1.mohitaws.tk\nServerAdmin webmaster@localhost\nDocumentRoot \/home\/cloud1\n\u00a0<IfModule mpm_itk_module>\nAssignUserId cloud1 cloud1\n\u00a0<\/IfModule>\nErrorLog ${APACHE_LOG_DIR}\/error.log\nCustomLog ${APACHE_LOG_DIR}\/access.log combined\n<\/VirtualHost>\n<VirtualHost *:80>\nServerName cloud2.mohitaws.tk\nServerAdmin webmaster@localhost\nDocumentRoot \/home\/cloud2\n<IfModule mpm_itk_module>\n\u00a0 AssignUserId cloud2 cloud2\n\u00a0 \u00a0<\/IfModule>\nErrorLog ${APACHE_LOG_DIR}\/error.log\nCustomLog ${APACHE_LOG_DIR}\/access.log combined\n<\/VirtualHost><\/pre>\n
\"apache\"<\/a><\/p>\n
\u00a0<\/div>\n
Note<\/strong><\/div>\n
We know that at the time of user creation, a primary group with the same username gets created and then the user is automatically assigned to that group.<\/p>\n
Therefore, we have mentioned user1 & user2 in place of groupname inside the IfModule tag which significantly corresponds to the primary group name of both users.<\/p>\n
So, don’t get it confused with the usernames rather than group names.<\/p>\n
Restart apache2 service :-<\/p>\n
service apache2 restart\u00a0\n<\/pre>\n
Hence, you have successfully enabled apache2-mpm-itk module and now each of your virtually hosted sites has its dedicated user.<\/p>\n
Now, when you browse your URL. It will show like this
https:\/\/cloud.mohitaws.tk\/\u00a0<\/a><\/p>\n
\"apache\"<\/a><\/p>\n
https:\/\/cloud1.mohitaws.tk\/\u00a0<\/a><\/p>\n
\"apache\"<\/a><\/p>\n
https:\/\/cloud2.mohitaws.tk\/<\/a><\/p>\n
\"apache\"<\/a><\/p>\n
Hence, you have successfully enabled apache2-mpm-itk module and now each of your virtually hosted sites has its dedicated user.<\/p>\n\n\n
