One-click installation tutorial for php on linux

In server environments using Linux systems, applications written in PHP are widely used. Before installing PHP, you must install a web server, such as Apache, because the web server is the running environment of PHP. Below is a tutorial on installing PHP in a Linux environment with one click.

Step 1: Install the Linux system

If the Linux system is not installed on the server, you need to install the Linux system first. In Linux systems, there are multiple distributions, such as Ubuntu, CentOS, and Debian. Users can choose the appropriate version according to their needs.

Step 2: Install APache

Before installing APache for the Linux server, you need to log in to the server with administrator rights. In Ubuntu system, you can use the following command to install Apache:

sudo apt-get update
sudo apt-get install apache2

In CentOS system, you can use the following command to install Apache:

sudo yum install httpd

In Debian system, you can use the following command to install Apache:

sudo apt-get update
sudo apt-get install apache2

Step 3: Install PHP

You can download the PHP source code from the PHP official website. After downloading, extract the source code to the "/usr/local/src" directory, for example in Ubuntu system:

sudo mkdir /usr/local/src
cd /usr/local/src
sudo wget http://cn2.php.net/get/php-7.3.17.tar.gz/from/this/mirror -O php-7.3.17.tar.gz
tar -xvf php- 7.3.17.tar.gz

Then, use the following command to call the PHP installation program and install according to the prompts:

cd php-7.3.17
sudo ./configure
--with-apxs2=/usr/local/apache2/bin/apxs
--with-mysqli=mysqlnd
--with-pdo-mysql=mysqlnd
--with-libdir=/ lib/x86_64-linux-gnu
--with-zlib
--enable-mbstring
--with-curl
--with-openssl
--enable-zip
--enable-fpm
sudo make
sudo make install

In each option of the above command, "/usr/local/apache2/bin/apxs" is the executable file when Apache is installed , if you install it in a different directory, adjust the value of this option accordingly.

Use the PHP-fpm module to achieve more efficient PHP processing in Apache. You can use the following command to install the PHP-fpm module in the Ubuntu system:

sudo apt-get install php7.3-fpm

In the CentOS system, you can use the following command to install the PHP-fpm module ：

sudo yum install php-fpm

In Debian system, you can use the following command to install the PHP-fpm module:

sudo apt-get install php7.3-fpm

Step 4: Test PHP installation

After installing PHP, you need to test whether PHP can work normally. You can create a test PHP file in the "/var/www/html" directory using the following command:

sudo nano /var/www/html/info.php

In the open file , enter the following:

phpinfo();
?>

Then save the file and close it. In the web browser, enter the server address (such as http://localhost/info.php). If you can see the PHP configuration information, it means that PHP has been installed correctly and can work normally.

Summary

Through the above steps, users can quickly install PHP in a Linux environment so that the server can support PHP applications. This tutorial uses PHP 7.3 version. In actual applications, users should choose the appropriate PHP version according to their actual needs.
