How to deal with the lack of PHP-FPM in Ubuntu
In the Ubuntu system, PHP-FPM is a commonly used PHP FastCGI process manager, used to handle the running of PHP programs. However, in some cases, PHP-FPM is missing, causing PHP to not run properly. This article will introduce how to deal with the lack of PHP-FPM in Ubuntu and provide specific code examples.
Problem Description
When PHP is installed in the Ubuntu system and PHP-FPM is enabled, sometimes PHP-FPM is missing, resulting in the inability to use PHP normally. This problem may be caused by PHP-FPM being incorrectly installed, misconfigured, or aborting abnormally at runtime.
Countermeasures
In order to solve the problem of PHP-FPM missing, we can follow the following steps:
Step 1: Check PHP-FPM status
First, we need to check the running status of PHP-FPM. You can use the following command to check whether PHP-FPM is running:
systemctl status php-fpm
If PHP-FPM is not running, you can use the following command to start the PHP-FPM service:
sudo systemctl start php-fpm
Step 2: Reinstall PHP-FPM
If you find that PHP-FPM is not installed or there is a problem with the installation, you can try to reinstall PHP-FPM. You can use the following command to install it:
sudo apt-get install php-fpm
Step 3: Check PHP configuration
Sometimes, the problem of missing PHP-FPM may be caused by an incorrect PHP configuration file. You can use the following command to view the path to the PHP configuration file:
php --ini
Then check whether the PHP-FPM configuration in the configuration file is correct. You can use an editor to open the PHP configuration file for inspection, for example:
sudo nano /etc/php/7.4/fpm/php-fpm.conf
Step 4: Restart PHP-FPM
After completing the above steps, we can try to restart the PHP-FPM service to apply Changed configuration:
sudo systemctl restart php-fpm
Conclusion
Through the above steps, we can solve the problem of missing PHP-FPM in Ubuntu and ensure that PHP can run normally. Whether it is checking PHP-FPM running status, reinstalling PHP-FPM, checking PHP configuration or restarting PHP-FPM, it can help fix PHP-FPM missing situation. I hope the above content will be helpful to readers who encounter similar problems.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
