[FreeBSD]apache2 (worker) + PHP5.2.6 + mod_fastcgi

基本上利用 FreeBSD 的 ports 安裝就可以了：
1. 先安裝 apache with MPM = worker

cd /usr/ports/www/apache22
make WITH_MPM=worker install clean
pkg_info | grep apache
#
# 會出現
#
apache-worker-2.2.9_5 Version 2.2.x of Apache web server with worker MPM.

2. 安裝 PHP5 跟 PHP5-extensions

cd /usr/ports/lang/php5; make install clean
cd /usr/ports/lang/php5-extensions; make install clean

3. 安裝 mod_fastcgi

cd /usr/ports/www/mod_fastcgi
make install clean

全部安裝完成，先修改 httpd.conf

#
# 把下面這行 umark 掉
#
# Server-pool management (MPM specific)
Include etc/apache22/extra/httpd-mpm.conf

修改 Include etc/apache22/extra/httpd-mpm.conf
mpm_worker_module 那段：

ThreadLimit 512
    StartServers 1
    MaxClients 512
    MinSpareThreads 1
    MaxSpareThreads 512
    ThreadsPerChild 512
    MaxRequestsPerChild 0

這樣 MPM worker 就設定完成了，接下來設定 mod_fastcgi

到 /usr/local/etc/apache22/httpd.conf 把底下這一段的註解拿掉

LoadModule fastcgi_module     libexec/apache22/mod_fastcgi.so

新增設定檔：/usr/local/etc/apache22/Includes/fastcgi.conf，內容如下：

#
FastCgiConfig -maxClassProcesses 1
ScriptAlias /fcgi-bin/ "/usr/local/www/fcgi-bin/"
<Directory /usr/local/www/fcgi-bin/>
    SetHandler fastcgi-script
    AllowOverride All
    Order allow,deny
    Allow from all
Directory>
#
AddHandler php-fastcgi .php
Action php-fastcgi /fcgi-bin/php

這裡設定只能跑一隻 配合前面的 MPM worker，這樣確保所有的 apache 只會透過這個 fastcgi socket 跑 php。
然後再建立： /usr/local/www/fcgi-bin 這個資料夾，裡面擺入執行檔 php 內容是：

#!/bin/sh
PHPRC="/usr/local/etc"
export PHPRC
PHP_FCGI_CHILDREN=128
export PHP_FCGI_CHILDREN
exec /usr/local/bin/php-cgi
