ubuntu10.04配备 nginx + php-fpm 模式

热度:1147   发布时间:2012-11-23 22:54:33.0
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  update

sudo  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

<?php
echo "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
	fi
done


#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
