Hosting multiple websites on one server is possible with virtual hosts. This method lets you set up Apache to handle different domain names. Each domain can have its own content and settings. This way, you can manage many websites from one place, saving resources and making server management easier.
This guide shows how to set up virtual hosts on an Ubuntu Linux server with Apache. We’ll create hosts for webserver1.com and webserver2.com. You can add more hosts as needed.
- Create separate directories for each virtual host under
/var/www. For example,/var/www/webserver1.comand/var/www/webserver2.com. - Change the permissions of
/var/wwwand its subdirectories. This lets normal users change the web content. Use these commands:sudo chown -R www-data:www-data /var/wwwsudo chmod -R 755 /var/www
- Make a simple
index.htmlfile in each directory. This will be a test page. - Create configuration files for the virtual hosts in
/etc/apache2/sites-available. For example,webserver1.com.confandwebserver2.com.conf. - In each file, add the necessary settings. This includes
ServerAdmin,ServerName,ServerAlias,DocumentRoot,ErrorLog, andCustomLog. - Enable the virtual host files by creating symbolic links in
/etc/apache2/sites-enabled:sudo a2ensite webserver1.com.confsudo a2ensite webserver2.com.conf
- Restart the Apache web server to apply the changes:
sudo systemctl restart apache2
- Edit the local
/etc/hostsfile. Add lines to map domain names to the server’s IP address for testing:127.0.0.1 webserver1.com127.0.0.1 webserver2.com
- Visit
http://webserver1.comandhttp://webserver2.comin your browser to test the virtual hosts.
By following these steps, you’ve set up virtual hosts on your Ubuntu Linux server with Apache. This lets you host many websites on one server. It saves resources and makes managing the server easier. You can add more hosts by repeating the process for each new website.
Securing Your Web Server

User Management and Permissions
Effective user management is key to a secure Linux web server. It helps control access to important resources and prevents unauthorized access. The principle of least privilege is a good guide.
This principle means users should only have the access they need. They shouldn’t have admin rights unless it’s really necessary. Also, delete any default accounts the OS sets up, as attackers often target them.
- In a single directory, up to 60,000 users can be created on a Linux system.
- The root user is assigned ID 0, while system users are allocated IDs from 1 to 999, and local user IDs start from 1000 onwards.
- The
useraddcommand is used to add a new user, automatically assigning an ID based on the user category. - To change a user’s ID, the
usermod -u new_id usernamecommand is utilized. - The
usermod -g new_group_id usernamecommand is employed to modify the group ID of a user. - The
usermod -l new_login_name old_login_namecommand allows changing the user login name. - The
usermod -d new_home_directory_path usernamecommand changes the home directory of a user. - To delete a user, the
sudo userdel -r usernamecommand is used, cautioning that users part of a group must be removed from the group first.
By following these best practices, you can keep your Linux web server secure. This limits access to only those who need it and reduces the risk of unauthorized access or misuse.
“Properly managing user accounts and permissions is crucial for maintaining a secure Linux web server environment.”
