How to install and configure Apache web server in Linux To install and configure Apache web server in Linux, you can follow these steps:
1. Install Apache
Run the following command to install Apache:
sudo apt install apache2
2. Start the Apache service
Once Apache is installed, you need to start the service. You can do this by running the following command:
sudo systemctl start apache2
3. Check the status of the Apache service
To verify that the Apache service is running, you can run the following command:
sudo systemctl status apache2
4. Configure Apache
The default Apache configuration file is located at /etc/apache2/apache2.conf. You can edit this file to configure Apache to your needs.
Some common configuration options include:
DocumentRoot: This directive specifies the directory where Apache will serve files from. The default value is /var/www/html.
Listen: This directive specifies the port that Apache will listen on. The default value is 80.
ServerName: This directive specifies the hostname or IP address of the server. This is used to generate the Server: header in HTTP responses.

You should see your test web page displayed in the browser.
7. Configure virtual hosts
If you want to host multiple websites on the same server, you can use virtual hosts. Virtual hosts allow you to configure different settings for each website, such as the DocumentRoot and ServerName.
To create a virtual host, create a file in the /etc/apache2/sites-available directory. The file name should end in .conf.
For example, to create a virtual host for the website example.com, you would create a file called example.com.conf.
The contents of the virtual host file will vary depending on your needs. However, here is a basic example:
VirtualHost *:80
ServerName example.com
DocumentRoot /var/www/example.com
/VirtualHost
Once you have created the virtual host file, you need to enable it. To do this, run the following command:
sudo a2ensite example.com.conf
Finally, you need to restart the Apache service for the changes to take effect. You can do this by running the following command:
sudo systemctl restart apache2
You can now visit the website in a web browser by navigating to the following URL:
