apache+php用fastcgi模式代替mod_php模式
apache下php配置fastcgi代替mod_php
（大红色字体表示关键部分）
环境rhed5.4
所需包
httpd-2.2.17.tar.gz php-5.2.13.tar.gz mod_fastcgi-2.4.6.tar.gz php-5.2.13-fpm-0.5.13.diff.gz
apache 的安装
#cd /usr/local/src/tarbag
# wget http://mirror.bjtu.edu.cn/apache//httpd/httpd-2.2.17.tar.gz
# tar -zxvf http-2.2.17.tar.gz -C ../software
# cd ../software/http-2.2.17
#./configure --prefix=/usr/local/apache2.2.17 --with-mpm=worker --enable-so --enable-rewrite --enable-headers --enable-expires --enable-mods-shared=all
# make
# make install
给apache安装 mod_fastcgi 模块
#cd /usr/local/src/tarbag
#wget http://www.fastcgi.com/dist/mod_fastcgi-2.4.6.tar.gz
#tar -zxvf mod_fastcgi-2.4.6.tar.gz -C ../softwar
#cd ../software/mod_fastcgi-2.4.6
#cp Makefile.AP2 Makefile
编辑Makefile文件
#vim Makefile
修改 apache的安装路径
top_dir=/usr/local/apache2.2.17
#make
#make install
查看在apache的modules的目录下是否有mod_fastcgi.so模块
有，则说明成功
Php的安装
#cd /usr/local/src/tarbag
#wget http://museum.php.net/php5/php-5.2.13.tar.gz
#tar -zxvf php-5.2.13.tar.gz -C ../software
#cd ../software/php-5.2.13.tar.gz
#wget http://php-fpm.org/downloads/php-5.2.13-fpm-0.5.14.diff.gz
在下一步要给PHP 打个补丁
#gzip -cd php-5.2.13-fpm-0.5.13.diff.gz | patch -d /usr/local/src/software/php-5.2.13 -p1
（这条的命令的作用解压php-5.2.13-fpm-0.5.13.diff.gz 给/usr/local/src/software/php-5.2.13 的顶层目录打上个补丁）
#./configure --prefix=/usr/local/php5.2.13 --with-config-file-path=/usr/local/php5.2.13/etc --enable-fastcgi --enable-force-cgi-redirect --enable-fpm --with-bz2 --with-curl --with-curlwrappers --enable-ftp --enable-sockets --disable-ipv6 --with-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-freetype-dir=/usr/local --enable-gd-native-ttf --with-iconv-dir=/usr/local --enable-mbstring --enable-calendar --with-gettext --with-libxml-dir=/usr/local --with-zlib --enable-zend-multibyte --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql
#make
#make install
#cp -a php.ini-dist /usr/local/php2.2.13/etc/php.ini
编辑php-fpm的配置文件 /usr/local/php5.2.13/etc/php-rmp.conf
将这两行的注释去掉
<!-- <value name="user">nobody</value> -->
<!-- <value name="group">nobody</value> -->
否则会出现如下错误
[ERROR] fpm_unix_conf_wp(), line 124: please specify user and group other than root, pool 'default'
这里试下是否安装rmp成功
#/usr/local/php5.2.13/sbin/php-fpm start
netstat -ntlp 查看9000端口是否开启，开启则代表插件安装成功
先关闭php
#/usr/local/php5.2.13/sbin/php-fpm stop
下面有两种方法来启用php
1.利用apache来管理php进程
#mkdir /usr/local/apache2.2.17/fcgi-bin
#ln -s /usr/local/php/bin/php-cgi /usr/local/apache2.2.17/fcgi-bin/php-cgi
如果用apache的内部的fpm(fastcgi process manager)
LoadModule fastcgi_module modules/mod_fastcgi.so 添加模块
#<IfModule fastcgi_module>
ScriptAlias /fcgi-bin/ "/usr/local/apache2.2.17/fcgi-bin/" 程序目录的别名
FastCgiServer /usr/local/apache2.2.17/fcgi-bin/php-cgi -processes 10
开启10个php进程
AddType application/x-httpd-php .php 添加php的格式
AddHandler php-fastcgi .php .php的文件都由php-fastcgi来处理
Action php-fastcgi /fcgi-bin/php-cgi php-fastcgi的程序的定义
<Directory "/usr/local/apache2.2.17/fcgi-bin/"> 设置放这个的程序目录的权限
SetHandler fastcgi-script 所有的文件由fastcgi-script来处理
Options FollowSymLinks
Order allow,deny
Allow from all
</Directory>
</IfModule>
2.如果用php-fpm来管理php进程
必须打开开启php-fpm进程
LoadModule fastcgi_module modules/mod_fastcgi.so 添加模块
<IfModule fastcgi_module>
ScriptAlias /fcgi-bin/ "/usr/local/apache2.2.17/fcgi-bin/"
# 将php进程管理交给127.0.0.1：9000，这正是php_fpm的监听端口
FastCgiExternalServer /usr/local/apache2.2.17/fcgi-bin/php-cgi -host 127.0.0.1:9000
AddType application/x-httpd-php .php
AddHandler php-fastcgi .php
Action php-fastcgi /fcgi-bin/php-cgi
<Directory "/usr/local/apache2.2.17/fcgi-bin/">
SetHandler fastcgi-script
Options FollowSymLinks
Order allow,deny
Allow from all
</Directory>
</IfModule>
重启apache
下面我们来做下性能的测试.
1. 使用fastCGI
[root@localhost http]# /usr/local/apache2.217/bin/ab -c 50 -n 800 http://lin.com/test.php
（总共请求800次，每次的并发数是50）
