简介:这是[ZT] 使用PHP-FPM (PHP FastCGI Process Manager)来对php-cgi进程进行管理的详细页面,介绍了和php,有关的知识、技巧、经验,和一些php源码等。

如果使用PHP-FPM (PHP FastCGI Process Manager)来对进程进行管理,则需要提前做如下工作:
先到官网下载与php版本对应的php-fpm补丁:PHP-FPM
假设:php源代码目录在:/usr/local/php/source/php-5.2.9,php-fpm下载到了/usr/local/php/source
cd /usr/local/php/sourcegzip -cd php-5.2.8-fpm-0.5.10.diff.gz | patch -d php-5.2.9 -p1
补丁打好以后,编译php的时候增加了下面几个参数:
?enable-fpm 激活fastcgi模式的fpm支持
?with-fpm-conf php-fpm的配置文件(默认是PREFIX/etc/php-fpm.conf)
?with-fpm-log php-fpm的日志文件(默认是PREFIX/logs/php-fpm.log)
?with-fpm-pid php-fpm的pid文件(默认是PREFIX/logs/php-fpm.pid)
编译的时候?enable-fpm当然是必须的,其它几项可以根据你自己的情况自行调整。
编译参数:
cd /usr/local/src/php-5.2.9./configure --enable-fastcgi --enable-fpm --prefix=/usr/local/php --with-config-file-path=/etcmakemake install
其它的一些php编译参数,这里就略去了。
稍等片刻,等php编译并安装好,下面开始配置php-fpm。
vi /etc/php-fpm.conf
php-fpm.conf是一个xml格式的纯文本文件,具体细节可以自己打开看看,基本上一看就明白了。在这里特别注意一下这几个配置字段::
#这个表示php的fastcgi进程监听的ip地址以及端口<value name="listen_address">127.0.0.1:9000</value> #表示php的fastcgi进程以什么用户以及用户组来运行<value name="user">nobody</value><value name="group">nobody</value> #是否显示php错误信息<value name="display_errors">0</value> #最大的子进程数目<value name="max_children">5</value>
下面运行php-fpm:
/usr/local/php/bin/php-cgi --fpm
现在php的fastcgi进程就已经在后台运行,并监听127.0.0.1的9000端口。
可以用ps和netstat来看看结果:
ps aux | grep php-cginetstat -tpl | grep php-cgi
安装好了php-fpm,那么它是怎么来达到我们最初的目的的呢?
很幸运,php-fpm自己就给我们准备了一个程序来控制fastcgi进程,这个文件在$PREFIX/sbin/php-fpm
运行一下:
/usr/local/php/sbin/php-fpm
该程序有如下参数:
start 启动php的fastcgi进程
stop 强制终止php的fastcgi进程
quit 平滑终止php的fastcgi进程
restart 重启php的fastcgi进程
reload 重新加载php的php.ini
logrotate 重新启用log文件
也就是说,在修改了php.ini之后,我们可以使用
/usr/local/php/sbin/php-fpm reload
这样,保持php的fastcgi进程持续运行的状态下,又重新加载了php.ini。

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.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
