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
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""$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
error_log /var/log/nginx/error.log;
sendfile on;
tcp_nopush on;
#keepalive的超时时间
keepalive_timeout 60;
open_file_cache max=204800 inactive=20s;
open_file_cache_min_uses 1;
open_file_cache_valid 30s;
tcp_nodelay on;
gzip on;
include /etc/nginx/conf.d/*.conf;
}
日志格式之间是用不可打印符号进行分隔的,ctrl+v && ctrl+a
nginx虚拟主机配置文件
upstream haolianxi_php {
server 127.0.0.1:9444;
}
server {
listen 192.168.1.137:7777;
access_log /var/log/nginx/haolianxi/haolianxi.access.log main;
error_log /var/log/nginx/haolianxi/haolianxi.error.log;
#通用匹配
location / {
root /srv/www/php/;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
access_log /var/log/nginx/haolianxi/location.default.access.log main;
error_log /var/log/nginx/haolianxi/location.default.error.log;
allow 192.168.1.0/24;
deny all;
}
#正则表达式匹配
#proxy the php scripts to php-fpm
location ~ \.php$ {

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;

}
## 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
