1.5-php-fpm配置文件
/usr/local/php/etc/php-fpm.conf 是php服务的配置
/usr/local/php/etc/php.ini 是php软件的全局配置.如:时钟
主要配置的是php服务的配置,自带服务样板很乱,首先清空,插入代码
> /usr/local/php/etc/php-fpm.conf 清空文件
vim /usr/local/php/etc/php-fpm.conf 其实删除注释后,也就是下面的代码
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock 监听的方式,一般为sockte 可以自定义,自动生成
user = php-fpm
group = php-fpm
pm = dynamic 动态的,管理下面的代码
pm.max_children = 50 最大50个子进程
pm.start_servers = 20 一开始启动20子子进程,即启动php就启动20个进程
pm.min_spare_servers = 5 最小子进程5个
pm.max_spare_servers = 35 最多35个子进程
pm.max_requests = 500 一个子进程在它的生命周期内,一共处理500个请求。自动销毁
rlimit_files = 1024 每一个进程,它所使用的文件描述符的限制,大点也没关系
slowlog = /tmp/www_slow.log 追踪网站,排查网站慢的日志
request_slowlog_timeout = 1 脚本超时1秒,记录到上条路径的slow.log中
php_admin_value[open_basedir]=/data/www/:/tmp/ 指定php有权限的目录
代码分为两个部分
1.global 全局配置,主要是pid和错误日志
2.www为服务配置,
如果配置中pm = static 那么只有pm.max_children = 50生效,也就是启动就有50个进程,其它不生效。
建议使用dynamic 一开始会启动20个pool,如果空闲,则一个个销毁,直到最小5个为止。
多个pool的配置 不同域名,对应不同pool。有2个好处,1可以为不同的网站赋予不同的权限2一个网站挂掉,不影响其他pool的网站。
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/www.sock
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
slowlog = /tmp/www_slow.log
request_slowlog_timeout = 1
[www1] 改动1
listen = /tmp/www1.sock 改动2
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
slowlog = /tmp/www1_slow.log
request_slowlog_timeout = 1
课后答疑:
1:有两个问题1 这个listen = /tmp/php-fcgi.sock 什么时候写sock 什么时候用127.0.0.1:9000呢?
2 php-fmp里面php_admin_value[open_basedir] =/data/www/ 和nginx里面的虚拟主机配置文件root /data/aaa 如果这两个同时配置了那个目录会生效呢?
答:1. listen你愿意用哪个就哪个,都差不多,但有的人认为socket性能要比ip:port的形式高效,在我看来都差不多。
2. nginx配置的只是一个网站根目录,而php里面的open_basedir 是限定php的,你这样设置后,发现你的网站根本就不能运行了。
2:php-fpm设置了多个池子,如果需要每个pool指定不同的用户,那用户是在php编译安装时在这里--with-fpm-user=php-fpm如何绑定多个用户呢
答:上面那个是默认的,我们还可以在配置文件里定义额外的。
3:理解不了socket是什么
答:就是用来通信的文件,类似tcp/ip的通信机制,这种文件是unix/linux系统里面特有的。像mysql的数据通信,我们就可以使用socket文件通信。

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

In PHPOOP, self:: refers to the current class, parent:: refers to the parent class, static:: is used for late static binding. 1.self:: is used for static method and constant calls, but does not support late static binding. 2.parent:: is used for subclasses to call parent class methods, and private methods cannot be accessed. 3.static:: supports late static binding, suitable for inheritance and polymorphism, but may affect the readability of the code.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.
