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

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!
