Apache Server Debian 9 Configuration

Step 1: Install Apache on Debian 9

The first step in configuring Apache on Debian 9 is to install the Apache package. You can do this by running the following command:

Command	Description
sudo apt-get update	Update the package index on your server
sudo apt-get install apache2	Install Apache on Debian 9

Once you have installed Apache, you can start the service by running the following command:

sudo systemctl start apache2

Step 2: Configure Apache

After installing Apache, the next step is to configure it. You can configure Apache by editing the configuration file located at /etc/apache2/apache2.conf. Here are some key settings you may want to modify:

ServerName

You can set the ServerName directive to specify the hostname or IP address that should be used when responding to requests. This is useful if you have multiple domains or IP addresses assigned to your server.

DocumentRoot

The DocumentRoot directive specifies the directory where Apache should look for files to serve. You can set this to the root directory of your website.

ErrorLog and CustomLog

You can use the ErrorLog and CustomLog directives to specify the file where Apache should log errors and requests, respectively.

Step 3: Enable SSL

If you want to secure your website with SSL, you can enable it by running the following command:

sudo a2enmod ssl

This will enable the SSL module in Apache. You can then create a self-signed SSL certificate by running the following command:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt

Step 4: Enable HTTP/2

If you want to enable HTTP/2 on your Apache server, you can do so by enabling the http2 module. You can enable the module by running the following commands:
