This article explains how to install Apache® on a Debian® 10 server.

What is Apache?

Apache is an open-source, cross-platform web server that the Apache Software Foundation actively maintains.

Prerequisites

User with sudo privileges
Server running Debian 10
Uncomplicated Firewall (UFW) firewall

Step 1: Update and install Apache

Run the following command to open the terminal and update the repository:

`# sudo apt update`

Then, install the apache package:

`# sudo apt install apache2`

Step 2: Verify the installation

Run the following command:

`# sudo systemctl status apache2`

Notice the active (running) message in the following response:

    ● apache2.service - The Apache HTTP Server
       Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
       Active: active (running) since Thu 2021-03-11 09:56:58 CST; 1 weeks 0 days ago
         Docs: https://httpd.apache.org/docs/2.4/
      Process: 2141 ExecReload=/usr/sbin/apachectl graceful (code=exited, status=0/SUCCESS)
     Main PID: 6087 (apache2)
        Tasks: 55 (limit: 1158)
       Memory: 10.4M
       CGroup: /system.slice/apache2.service
               ├─2147 /usr/sbin/apache2 -k start
               ├─2148 /usr/sbin/apache2 -k start
               └─6087 /usr/sbin/apache2 -k start

Step 3: Access Apache

To access the server, you must know the IP address, so run the following command to find the IP address:

`# hostname -I`

If you type the IP address in your browser, an error loading the page appears. This error occurs because you have not yet added the HTTP rule to the firewall.

Step 4. Add firewall rules

Run the following commands to add the rule WWW to the firewall and permit the inbound and outbound traffic:

`sudo ufw allow 'WWW'`
`sudo ufw status  | grep 80/tcp`

The following example shows firewall rules on the server:

    80/tcp                     ALLOW       Anywhere\n
    80/tcp (v6)                ALLOW       Anywhere (v6)

Step 5: Verification

Type the IP address from Step 3 in your browser, and the Apache landing page appears.

Additional actions

The following commands can help you manage Apache:

Command	Action
`sudo systemctl stop apache2`	Stop
`sudo systemctl start apache2`	Start
`sudo systemctl restart apache2`	Restart
`sudo systemctl enable apache2`	Start automatically on server boot
`sudo systemctl disable apache2`	Deactivate the automatically start

Conclusion

After you complete these steps, Apache is running on your server and is ready to deploy an application.
