终于解决FreeBSD下Nginx做前端 FastCGI的PHP出现问题的情况了，原因很囧

过程如下：

ecjtu# whereis php-cgi

php-cgi: /usr/local/bin/php-cgi

ecjtu# spawn-fcgi -a 127.0.0.1 -p 139 -C 64 -f /usr/local/php/bin/php-cgi     

spawn-fcgi: child exited with: 127

ecjtu# spawn-fcgi -a 127.0.0.1 -p 139 -C 64 -u www -f /usr/local/bin/php-cgi

spawn-fcgi: child exited with: 13

ecjtu# spawn-fcgi -a 127.0.0.1 -p 139 -C 64 -U www -f /usr/local/bin/php-cgi

spawn-fcgi: child spawned successfully: PID: 39766

现在OK了

莫非127错误是php-cgi位置错误  13错误是大写U写成了小写u
