ubuntu10.04配置 nginx + php-fpm 模式

ppa安装php-fpm


安装工具包

$ sudo apt-get install python-software-properties 

添加ppa源

$  sudo add-apt-repository ppa:yola/php5

安装php5-fpm

sudo  apt-get  updatesudo  apt-get install  php5-fpm

其它必要的软件安装接

sudo   apt-get   install   nginx

配置php-fpm


php-fpm的解析器是C/S结构,它的配置文件位于:

(1)/etc/php5/fpm/php-fpm.conf 

(2)/etc/php5/fpm/pool.d/

一般没什么严格的配置的要求,或者说这块我还没有具体的研究每个配置参数的意义

我采用了tcp模式与fastcgi进程进行连接,因此我修改了tcp监听的地址和端口,修改了一下监视目录的名称,这里不做具体详细解释了,大家可以参考官方文档根据自己的需求进行配置


重启php5-fpm



配置nginx


前言

nginx本身并不会对php语言进行解析,这个区别于apache(apache有在带的mod_php模块进行php解析).nginx是通过fastcgi将客户端的php请求交给后台的php5-fpm进程管理器,php5-fpm具有解析php的功能,具体可以参考我之前的一篇博客mod_php对比mod_fastcgi


nginx的主配置文件

文件位置:/etc/nginx/nginx.conf,我的配置参数如下:

user  www-data;#主动开启cpu多核功能worker_processes  2;worker_cpu_affinity 01 10;#指定nginx进程可以打开的最大文件描述符数量worker_rlimit_nofile 65535;pid /var/run/nginx.pid;events {	#使用epoll的I/O模型	use epoll;	#工作单进程的并发连接数,总体并发连接数 = worker_connections * worker_processes	worker_connections 2048;	#multi_accept在Nginx接到一个新连接通知后调用accept()来接受尽量多的连接	multi_accept on;}http {	include       /etc/nginx/mime.types;	default_type  application/octet-stream;	charset utf-8;		server_names_hash_bucket_size 128;	client_header_buffer_size 2k;	large_client_header_buffers 4 4k;	#通过nginx上传文件的大小	client_max_body_size 8m;		#$remote_addr:记录ip地址;$remote_user:记录远程客户端用户名称;$request:请求的url和http协议;$status:用于记录请求状态;$body_bytes_sent:用于记录发送给客户端文件主体内容的大小;$http_referer:跳转链接;$http_x_forwarded_for:客户的真实ip地址	log_format  main  '$server_name$remote_addr$remote_user[$time_local]"$request"'                      '$status$body_bytes_sent"$http_referer"'                      '"$http_user_agent""$http_x_forwarded_for"';	access_log	/var/log/nginx/access.log  main;	error_log	/var/log/nginx/error.log;		sendfile        on;	tcp_nopush     on;	#keepalive的超时时间	keepalive_timeout  60;	open_file_cache max=204800 inactive=20s;	open_file_cache_min_uses 1;	open_file_cache_valid 30s;    	tcp_nodelay on;    	gzip  on;    	include /etc/nginx/conf.d/*.conf;}
日志格式之间是用不可打印符号进行分隔的,ctrl+v && ctrl+a


nginx虚拟主机配置文件

upstream haolianxi_php {	server 127.0.0.1:9444;}server {	listen	192.168.1.137:7777;		access_log	/var/log/nginx/haolianxi/haolianxi.access.log main;	error_log	/var/log/nginx/haolianxi/haolianxi.error.log;	#通用匹配		location / {		root	/srv/www/php/;		autoindex on;		autoindex_exact_size off;		autoindex_localtime on;		access_log	/var/log/nginx/haolianxi/location.default.access.log	main;			error_log	/var/log/nginx/haolianxi/location.default.error.log;		allow 192.168.1.0/24;		deny all;	}	#正则表达式匹配		#proxy the php scripts to php-fpm	location ~ \.php$ {		root	/srv/www/php/;		include	/etc/nginx/fastcgi_params;		fastcgi_pass	haolianxi_php;	# The upstream determined above		fastcgi_index	index.php;	}	#php-fpm status monitor	location = /phpfpm_status {		fastcgi_pass 127.0.0.1:9444;		fastcgi_index index.php;		include /etc/nginx/fastcgi_params;		allow	192.168.1.127;		allow	127.0.0.1;		deny all;	}	## Compression	# src: http://www.ruby-forum.com/topic/141251	# src: http://wiki.brightbox.co.uk/docs:nginx    	gzip on;    	gzip_http_version 1.0;    	gzip_comp_level 2;    	gzip_proxied any;    	gzip_min_length  1100;    	gzip_buffers 16 8k;    	gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;        	# Some version of IE 6 don't handle compression well on some mime-types, so just disable for them    	gzip_disable "MSIE [1-6].(?!.*SV1)";        	# Set a vary header so downstream proxies don't send cached gzipped content to IE6    	gzip_vary on;    	## /Compression}

注意:

include /etc/nginx/fastcgi_params中一个参数设置需要修改,修改如下:

fastcgi_param   SCRIPT_NAME             $document_root$fastcgi_script_name;

因为脚本的名称不加上$document_root,php5-fpm是无法找到需要执行的php脚本的绝对路径的


重启nginx

sudo  /etc/init.d/nginx  restart

测试fastcgi_finish_request()函数

<?phpecho "OK";fastcgi_finish_request();	/* 响应完成, 关闭连接 */sleep(5);file_put_contents("/tmp/fastcgi.log", "hello",FILE_APPEND);sleep(5);file_put_contents("/tmp/fastcgi.log", "world",FILE_APPEND);?>

说明:

用最大的白话说,fastcgi_finish_request()可以提前关闭和客户端的连接,把需要返回的数据返回给客户端,但是函数之后的分支业务逻辑还是继续在后台运行!


php5-fpm日志按天分割脚本

#!/bin/bash - #1.php5-fpm日志存放路径php5_fpm_logs_path="/var/log/php5-fpm/"category_array=("access" "error")#2.php5-fpm日志名后缀postfix=`date -d '-1 days' +%Y%m%d`".log"#3.php5-fpm日志切割for category in ${category_array[*]}do	if [ -e $php5_fpm_logs_path/php5-fpm.$category.log ]	then		mv $php5_fpm_logs_path/php5-fpm.$category.log \			$php5_fpm_logs_path/php5-fpm.$category.$postfix	fidone#4.查找php5-fpm进程号,让其产生新的日志文件php5fpm_pid=`ps -aux |grep -E 'php-fpm: master process'|grep -v 'grep'|awk '{print $2}'`#USR1:Reopen log files,刷新nginx日志文件kill -USR1 $php5fpm_pid

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
