How to install and configure PHP environment in Lunix

Lunix operating system is known for its stability and reliability. As a developer, you may be faced with a situation where you need to install a PHP environment on Lunix. This article explains how to install and configure a PHP environment on Linux.

Step 1: Install Apache

First, you need to install Apache, because PHP runs as an extension of Apache. You can install Apache through the following command:

sudo apt-get update

sudo apt-get install apache2

Step 2: Install PHP

Before installing PHP, you need to install the PHP extension compiler and other necessary libraries:

sudo apt-get install libapache2-mod-php php-cli php-mbstring php-json php-mysql

Step 3: Set up PHP

After installing PHP, you need to configure it. Use the following command in the terminal to configure:

sudo nano /etc/php/7.x/apache2/php.ini

Please note that 7.x is the PHP version number in your system. You can run the php -v command in the terminal to check your PHP version number.

In the php.ini file, you can configure various configurations for the PHP server, such as upload file size limits and error reporting. To make PHP more secure, we recommend turning on the following two settings:

display_errors = Off
display_startup_errors = Off

Step 4: Restart Apache

Once you have finished configuring PHP, you need to restart the Apache server to make the changes Effective:

sudo service apache2 restart

Step 5: Test PHP

You can test whether PHP is installed correctly by creating an info.php file. Enter the following command in the terminal:

sudo nano /var/www/html/info.php

This will create a new file named info.php. Add the following code to this file:

<?php phpinfo();
?>

Save changes and close the file. Then, open a web browser and navigate to http://your-server-ip/info.php. You should be able to see the PHP information page, which includes information such as PHP version and configuration settings.

Conclusion
