php+nginx配置权限问题(13: Permission denied)

ps查看nginx数据：
_www 508 0.0 0.0 2461508 1320 ?? S 10:46下午 0:00.00 nginx: worker process
_www 507 0.0 0.0 2452292 952 ?? S 10:46下午 0:00.80 nginx: worker process
root 506 0.0 0.0 2442864 348 ?? Ss 10:46下午 0:00.00 nginx: master process nginx

我的文档目录为:/Users/Abner/Documents/work/code/ququ/ms
nginx，php-fpm配置好后，浏览器访问:File not found.
查看日志：
2014/07/01 23:42:45 [crit] 508#0: *9 stat() "/Users/Abner/Documents/work/code/ququ/ms/" failed (13: Permission denied), client: 127.0.0.1, server: a.ququ.com, request: "GET / HTTP/1.1", host: "a.ququ.com"
2014/07/01 23:42:45 [error] 508#0: *9 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: a.ququ.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "a.ququ.com"

查了目录权限:704172 drwxr-xr-x 9 Abner staff 306 6 30 14:54 ms
755，按道理说是可以读数据啊。

但是怎么都是File not found，还请各位大神指导，多谢

/Users/Abner/Documents/work/code/ququ/ms
这些路径得逐层查看，看看是不是每层都有权限，不要只看最后一个目录
