cd /usr/ports/www/apache22
make WITH_MPM=worker install clean

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

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

httpd.conf 中新增or把註解拿掉這兩行
LoadModule fastcgi_module libexec/apache22/mod_fastcgi.so
Include etc/apache22/extra/httpd-mpm.conf

新增/usr/local/etc/apache22/Includes/fastcgi.conf

AddType application/x-httpd-php .php

ScriptAlias /php-fcgi "/usr/local/bin/php-cgi"

FastCgiServer "/usr/local/bin/php-cgi" -initial-env PHP_FCGI_CHILDREN=32

<directory /usr/local/bin >
  Options ExecCGI FollowSymLinks
  SetHandler fastcgi-script
  Order allow,deny
  Allow from all
</directory>

Action application/x-httpd-php /php-fcgi

ps
若之前php 是用php5_module來啟的話
記得把相關的php 都重編…
不然會一直出現
kernel: pid 86212 (php-cgi), uid 80: exited on signal 11
若一直出現這個就先把extension 都先拔掉
