Install LAMP Stack on Ubuntu 20.04
As per the acronym, Linux system is the first component of LAMP stack. And since you are here, Ubuntu 20.04 is our first component of LAMP stack.
Run System Update
To begin with, update and upgrade your system packages;
Install Apache Web Server on Ubuntu 20.04
Apache web server can be installed by running the command below;
apt install apache2
Once the installation is done, start and enable Apache to run on system boot.
systemctl enable --now apache2
If you going to be accessing Apache from your external system, then you need to allow it on firewall, that is, in case UFW is running;
ufw allow Apache
or simply run
ufw allow 80/tcp to allow HTTP traffic.
Verify external access to Apache by navigating to your browser and entering the server IP address or hostname as
http://Server.IP_or_hostname. You should land on Apache HTTP server test page.
