Step 2: Configure Apache Web Server
After installing Apache web server, you need to configure it to suit your requirements. The configuration files for Apache web server are usually stored in the /etc/apache2/ directory. The two main configuration files are httpd.conf and apache2.conf. You can open these files using a text editor and make the necessary changes. Here are some common configurations:
- Document Root: This is the directory where your web documents are stored. You can configure the document root by changing the DocumentRoot parameter in httpd.conf or apache2.conf.
- Virtual Hosts: You can configure Apache web server to host multiple websites on a single server by creating virtual hosts. Virtual hosts are defined in the /etc/apache2/sites-available/ directory and enabled using the a2ensite command.
- Directory Access: You can restrict access to certain directories on your web server by configuring the .htaccess file in the directory. The .htaccess file allows you to set access controls, password protection, and other security measures.
Step 3: Test Apache Web Server
