nginx php development environment setup

With the rapid development of the Internet, Web development has become an inevitable part of the IT industry. In web development, Nginx and PHP are two inevitable key technologies. This article will introduce how to set up a development environment for Nginx and PHP to help beginners get started quickly.

1. Install Nginx

Nginx is a high-performance web server software that supports reverse proxy, load balancing, caching and other functions. In this chapter, we will introduce how to install and configure Nginx.

(1) Install Nginx

In the Ubuntu system, use the following command to install the Nginx software:

sudo apt-get install nginx

(2) Start the Nginx service

Installation completed After that, use the following command to start the Nginx service:

sudo systemctl start nginx

(3) Check the Nginx status

Use the following command to check the Nginx status:

sudo systemctl status nginx

If the status is displayed as active (running ), it means that Nginx has been started successfully.

2. Install PHP

PHP is a scripting language for writing web applications. It can work with Nginx to provide services. In this chapter, we will introduce how to install PHP and configure it to work with Nginx.

(1) Install PHP

In Ubuntu system, use the following command to install PHP software:

sudo apt-get install php-fpm

(2) Configure PHP

After installation is completed , some configuration is required so that PHP can work with Nginx. First edit the php.ini file:

sudo nano /etc/php/7.2/fpm/php.ini

In the open file, find the following three lines:

;cgi.fix_pathinfo=1

Change them to:

cgi.fix_pathinfo=0

This is done to prevent PHP from A security issue occurs when the interpreter handles parameters in URLs.

Next, you need to edit the Nginx site configuration file:

sudo nano /etc/nginx/sites-available/default

Add the following content at the end of the file:

location ~* \.php$ {
    fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

This is done to enable the PHP program in Nginx, and Pass the request to the PHP interpreter.

Finally, restart the PHP service to make the above changes take effect:

sudo systemctl restart php7.2-fpm

3. Test environment

After setting up the development environment for Nginx and PHP, you need Test to make sure everything is working properly.

(1) Create a test file

First, create a file named info.php in the Nginx website root directory (default is /var/www/html/):

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

Add the following content to the file:

<?php phpinfo();
?>

This is a basic function of PHP, used to display the current PHP configuration information.

(2) Visit the test page

and enter the following URL in the web browser:

http://服务器IP地址/info.php

where the server IP address refers to the IP of the server you are using address. If everything is fine, you should be able to see a detailed list of PHP configuration information in your browser.

At this point, the development environment for Nginx and PHP has been set up. You can install and configure other web development-related software as needed, such as databases, version control tools, etc., to better manage and develop web applications.
