Install Apache on Debian 9 Server - Step by Step Process ?

This article covers how to install an Apache web server on your Debian 9 server. The Apache HTTP server is the most widely-used web server in the world. It provides many powerful features including dynamically loadable modules, robust media support, and extensive integration with other popular software.


How to Install Apache ?

1. Let's begin by updating the local package index to reflect the latest upstream changes:

$ sudo apt update

2. Then, install the apache2 package:

$ sudo apt install apache2

 After confirming the installation, apt will install Apache and all required dependencies.


The Apache profiles begin with WWW:

1. WWW: This profile opens only port 80 (normal, unencrypted web traffic).

2. WWW Cache: This profile opens only port 8080 (sometimes used for caching and web proxies).

3. WWW Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic).

4. WWW Secure: This profile opens only port 443 (TLS/SSL encrypted traffic).


How to Manage Apache Process ?

To stop your web server, type:

$ sudo systemctl stop apache2

To start the web server when it is stopped, type:

$ sudo systemctl start apache2

To stop and then start the service again, type:

$ sudo systemctl restart apache2

If you are simply making configuration changes, Apache can often reload without dropping connections. To do this, use this command:

$ sudo systemctl reload apache2

By default, Apache is configured to start automatically when the server boots. If this is not what you want, disable this behavior by typing:

$ sudo systemctl disable apache2

To re-enable the service to start up at boot, type:

$ sudo systemctl enable apache2

Apache should now start automatically when the server boots again.
