手动编译php + nginx ,fastcgi模式.nginx配置好后,访问php一片空白

nginx 配置:

------------------------------
#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
worker_connections 1024;
}


http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;
br /> sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;

server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root /www/default;
index index.html index.htm index.php;
}

location ~.*\.php$ {
root /www/default;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
}
}

------

$ netstat -anl | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN


------

每访问刷新一次

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:9000 127.0.0.1:34246 TIME_WAIT
tcp 0 0 127.0.0.1:9000 127.0.0.1:34245 TIME_WAIT
tcp 0 0 127.0.0.1:9000 127.0.0.1:34243 TIME_WAIT
tcp 0 0 127.0.0.1:9000 127.0.0.1:34247 TIME_WAIT


------

/www/default/
├── 1.txt
└── index.php

------

访问1.txt 正常... index.php内容:
<?php
phpinfo();
?>

访问index.php 一片空白,访问任何*.php 也是全空白。不提示404
