Linux Source Package Installation And Uninstallation (Take Apache As An Example)

In this tutorial, we'll learn how to install and uninstall a Linux source package, using Apache HTTP Server as an example. Installing from source code allows you to have the latest features and custom configuration options that may not be available in the pre-built packages.

Prerequisites

Update your system:

For Debian/Ubuntu-based systems:

sudo apt update && sudo apt upgrade

For CentOS/RHEL-based systems:

sudo yum update

Install necessary development tools:

For Debian/Ubuntu-based systems:

sudo apt install build-essential

For CentOS/RHEL-based systems:

sudo yum groupinstall "Development Tools"

Installing Apache HTTP Server from Source

Download the latest Apache source code from the official website (https://httpd.apache.org/download.cgi) or use wget to download it:

wget https://downloads.apache.org/httpd/httpd-2.4.51.tar.gz

Extract the source code:

tar xvf httpd-2.4.51.tar.gz

Change to the extracted directory:

cd httpd-2.4.51

Install the required dependencies:

For Debian/Ubuntu-based systems:

sudo apt-get install libapr1-dev libaprutil1-dev libpcre3-dev libssl-dev

For CentOS/RHEL-based systems:

sudo yum install apr-devel apr-util-devel pcre-devel openssl-devel

Configure the source code with the desired options. In this example, we'll use the default options and install Apache under /usr/local/apache2:

./configure --prefix=/usr/local/apache2

Compile the source code:

make

Install the compiled package:

sudo make install

Start Apache:

sudo /usr/local/apache2/bin/apachectl start

Apache HTTP Server is now installed and running. You can access the default page by visiting http://localhost in your browser.

Uninstalling Apache HTTP Server

To uninstall the Apache HTTP Server installed from the source, follow these steps:

Stop Apache:

sudo /usr/local/apache2/bin/apachectl stop

Remove the installation directory:

sudo rm -rf /usr/local/apache2

Optional: Remove the source code directory:

rm -rf httpd-2.4.51

By following this tutorial, you have learned how to install and uninstall a Linux source package using Apache HTTP Server as an example. This method can be applied to other software packages when you need the latest features or custom configuration options not available in the pre-built packages. Keep in mind that installing from source requires more time and effort compared to using package managers, and you'll need to manually manage updates and dependencies.
