PHP-FPM & Nginx on Ubuntu 18.04
Introduction to PHP-FPM
PHP-FPM (FastCGI Process Manager) is an implementation of FastCGI, which is a standard protocol for interfacing external applications with web servers. It is a system used for running scripts written in the PHP programming language in response to web requests. Instead of using the standard web server to process PHP files, the FPM system takes over this job and handles it directly. This frees up the web servers to handle other requests and allows PHP to be executed more efficiently. With FPM, the PHP syntax can also be updated without having to restart the web server.
With PHP-FPM, the PHP files can run in a separate process, which can have more control over the system’s resources. For example, the FPM system can allocate more memory or CPU time for the PHP scripts, or it can limit the amount of resources provided to each script. It also limits the number of requests that can be processed at the same time, which helps to prevent a build-up of simultaneous requests.
Advantages of using PHP-FPM
There are several advantages to using PHP-FPM instead of the standard web server. First, it allows great scalability since the system can process thousands of requests at the same time. Secondly, it can be used to limit the resources that processes can use up, preventing them from monopolizing the system resources. Finally, it allows developers to use a variety of different PHP syntax when creating their application.
In addition to the above advantages, using FPM greatly reduces server workload. This is because the system will take requests directly to the PHP scripts instead of going through the web server. This simplifies the process and reduces the need for the web server to process files, resulting in a much faster experience for the end-user. In addition to this, FPM allows for more flexibility as developers can use different versions of the PHP language.
Installing Nginx and PHP-FPM on Ubuntu
The first step is to install Nginx web server and PHP-FPM on your Ubuntu system. To do this, open a terminal window and run the following commands:
sudo apt update
sudo apt install nginx
sudo apt install php7.0-fpm
The above commands will install all the necessary packages for running Nginx and PHP-FPM. Once the installation is complete, you will need to configure the Nginx web server to work with PHP-FPM. To do this, open the Nginx configuration file with a text editor and locate the ‘fastcgi_pass’ directive.
Once you have located this directive, add the following line to it:
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
This will tell Nginx that all requests should be forwarded to PHP-FPM. Save the configuration file and restart Nginx with the following command:
sudo systemctl restart nginx
Now that Nginx and PHP-FPM are configured, you can begin using PHP in your projects. To test it out, create a file called ‘test.php’ in the root directory of your web server and add the following code to it:
Save the file and then open it in a web browser. If everything is configured correctly, you should see the message “Hello World!”.
