What is the situation if linux does not have php-fpm?

Linux does not have php-fpm?

This may seem a bit strange. After all, php-fpm is a widely used PHP FastCGI process manager, which can greatly improve the performance and stability of PHP.

However, not all Linux distributions actually come with php-fpm pre-installed. Especially some lightweight distributions, such as Alpine Linux, may not have php-fpm or need to be installed manually.

Although not having php-fpm may cause some problems, we can deal with this problem in the following ways:

1. Manually install php-fpm

First, we can try to install php-fpm manually. In most cases, php-fpm is installed as a component of PHP. We only need to search for "php-fpm" in the package manager and install it. For example, on Ubuntu, we can use the following command to install php-fpm:

sudo apt-get install php-fpm

If you are using other distributions, please follow their corresponding package manager and installation method.

2. Use another PHP process manager

If your Linux distribution really does not have php-fpm, then you can consider using another PHP process manager. For example, you can use the cli-server that comes with PHP, or install other third-party process managers, such as Swoole or RoadRunner.

3. Integrate PHP directly into the Web server

Finally, we can also consider integrating PHP directly into the Web server. For example, in Nginx, we can use "php-cgi" or "php-fcgi" to handle PHP scripts. Similarly, Apache can also use mod_php to implement PHP processing. Although these methods may not be as efficient as php-fpm, they are sufficient for some small websites and applications.

In short, not having php-fpm pre-installed in Linux is not a big problem. We can install it manually, use another process manager, or integrate PHP directly into the web server. As long as we know how to deal with it, we can naturally solve this problem.
