编译安装LAMP之配置httpd以FastCGI方式与php整合
./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr--enable-xml--enable-sockets--enable-fpm--with-mcrypt--with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2make
make install
# cp sapi/fpm/init.d.php-fpm/etc/init.d/php-fpm 复制启动脚本
# chmod +x /etc/init.d/php-fpm
# chkconfig --add php-fpm
# chkconfig php-fpm on
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf 复制一个配置文件给php-fpm
# vim /usr/local/php/etc/php-fpm.conf
pm.max_children = 50 最多有多少个子进程
pm.start_servers = 5 刚启动时有几个空闲进程
pm.min_spare_servers = 2 最少有几个空闲进程
pm.max_spare_servers = 8 最多有几个空闲进程
pid =/usr/local/php/var/run/php-fpm.pid 定义pid文件
service php-fpm start

fpm默认鉴定在9000端口
配置httpd
[*]启用httpd的相关模块
在Apache httpd 2.4以后已经专门有一个模块针对FastCGI的实现，此模块为mod_proxy_fcgi.so,它其实是作为mod_proxy.so模块的扩充，因此，这两个模块都要加载
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
[*]配置虚拟主机支持使用fcgi
在相应的虚拟主机中添加类似如下两行。
ProxyRequests Off 关闭apache的正向代理功能
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/PATH/TO/DOCUMENT_ROOT/$1 把以.php结尾的文件请求发送到php-fpm进程，php-fpm至少需要知道运行的目录和URI,所以这里直接在fcgi://127.0.0.1:9000 后指明了这两个参数，其他的参数的传输已经被mod_proxy_fcgi.so进行了封装，不需要手动指定。
Apache httpd 2.4 以前的版本中，要么把PHP作为Apache的模块运行，要么添加一个第三方模块支持PHP-FPM实现。
列如：
<VirtualHost *:80>
DocumentRoot "/www/a.org"
ServerName a.org
ServerAlias www.a.org
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/www/a.org/$1
<Directory "/www/a.org">
Options none
AllowOverride none
Require all granted
</Directory>
</VirtualHost>
--------------------------------------------------------
# cp php.ini-production/etc/php.ini
# vi /etc/httpd/httpd.conf
#DocumentRoot "/usr/local/apache/htdocs" 注释掉中心主机
#Virtual hosts 启用虚拟主机
Include /etc/httpd/extra/httpd-vhosts.conf
# vim /etc/httpd/extra/httpd-vhosts.conf
<VirtualHost *:80>
DocumentRoot "/www/a.org"
ServerName www.a.org
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/www/a.org/$1
<Directory "/www/a.org">
Options none
AllowOverride none
Require all granted
</Directory>
ErrorLog "/var/log/httpd/a.org-erro_log"
CustomLog "/var/log/httpd/a.org-access_log" combined
</VirtualHost>
# vim /etc/httpd/httpd.conf
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so 启用
LoadModule proxy_module modules/mod_proxy.so 启用
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-httpd-php .php 添加此行
AddType application/x-httpd-php-source .phps 添加此行
<IfModule dir_module>
DirectoryIndexindex.php index.html 让主也变支持index.php
</IfModule>
# apache/bin/apachectl start
# mv index.html index.php
然后还需要安装xcache
# cp config.m4../php/bin/
# ./phpize
