php 5.4中php-fpm 的重启、终止操作命令:
查看php运行目录命令:
which php
/usr/bin/php
查看php-fpm进程数:
ps aux | grep -c php-fpm
查看运行内存
/usr/bin/php -i|grep mem
重启php-fpm
/etc/init.d/php-fpm restart
在phpinfo()输出内容可以看到php相关配置。
Loaded Configuration File /etc/php.ini
==============================
首先要找到php-fpm.conf配置文件,查看pid的配置路径(不是安装路径),然后把下面对应的地方改掉才能正常执行。
[root@DO-SG-H1 ~]# ps aux | grep php-fpm
root 11799 0.0 0.0 103248 880 pts/0 S+ 13:51 0:00 grep --color php-fpm
root 11973 0.0 0.0 417748 964 ? Ss Jun01 0:20 php-fpm: master process (/etc/php-fpm.conf)
cat /etc/php-fpm.conf
看到
pid = /var/run/php-fpm/php-fpm.pid
php-fpm 启动:
/usr/local/php/sbin/php-fpm
php-fpm 关闭:
kill -INT `cat /var/run/php-fpm/php-fpm.pid`
php-fpm 重启:
kill -USR2 `cat /var/run/php-fpm/php-fpm.pid`
查看php-fpm进程数:
ps aux | grep -c php-fpm
=============================
[root@DO-SG-H1 ~]# find / -name 'php-fpm' -type d
/var/log/php-fpm
/var/run/php-fpm
用这个find命令查找出来的路径是不对的
which php
/usr/bin/php

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.
