系统环境
- ubuntu 8.04
- php-cgi 5.2.4
- nginx 0.6.34
- lighttpd 1.4.19 (需要其中的 spawn-fcgi 程序)
相关概念和链接
- fastcgi
相对于cgi为每个动态内容请求创建一个独立的进程,fastcgi能使用一个单独进行为多个动态内容请求进行相应
安装过程
apt-get install xxxx 
配置备注
nginx配置
- 备份nginx默认站点配置文件(/etc/nginx/sites-available/default) 或 以default为模板创建新文件并在 /etc/nginx/sites-enabled/ 中建立链接
- 修改站点配置文件中" location /" 起始段落为以下内容
location / {
#root /var/www/nginx-default;
root /home/lvs/code/php/virtual_host/chino/wwwroot ; #指向php工程DocumentRoot目录
index index.php index.html index.htm ; #添加index.php为站点默认访问索引文件
} - 修改站点配置文件中"location ~ \.php " 起始段落为以下内容
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000; #这个地址需要和fastcgi监听地址匹配
fastcgi_index index.php;
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME /home/lvs/code/php/virtual_host/chino/wwwroot$fastcgi_script_name;
#fastcgi_param 中,fastcgi_script_name前的值应设置为php工程 DocumentRoot
#TODO 需要找到以变量存储php 工程 DocumentRoot的方法
}
fastcgi环境建立
1. 创建 php fastcgi监听进程生产 脚本
-
- $sudo touch /usr/bin/php-fastcgi && 插入以下内容
#!/bin/sh
spawn-fcgi -a 127.0.0.1 -C 7 -p 9000 -u www-data -f /usr/bin/php5-cgi
#如果不安装lighttpd，可以下载lighttpd源码编译后提取spawn-fcgi程序
#指定产生7个 fastcgi 监听进程
- $sudo touch /usr/bin/php-fastcgi && 插入以下内容
2. 创建fastcgi 启动管理脚本
-
- $sudo touch /etc/init.d/php-fastcgi-spawner && 插入以下内容
#!/bin/bash
PHP_SCRIPT=/usr/bin/php-fastcgi #需要和上一步骤中php fastcgi监听进程生产脚本位置匹配
RETVAL=0
case "$1" in
start)
$PHP_SCRIPT
RETVAL=$?
;;
stop)
killall -9 php5-cgi
RETVAL=$?
;;
restart)
killall -9 php5-cgi
$PHP_SCRIPT
RETVAL=$?
;;
*)
echo "Usage: php-fastcgi {start|stop|restart}"
exit 1
;;
esac
exit $RETVAL
3. 如果需要系统启动自动运行:
-
- debian系在/etc/rc2.d/ 中创建S字头链接
- redhat系在/etc/rc3.d/ (文本环境 ) 或 /etc/rc5.d/ (图形环境) 创建链接
性能测试
以 $ab -c 50 -n 2000 对分别使用nginx&fastcgi和apache&mod-php 运行的同一php页面进行测试
