odeigniter（CI）是一个轻量型的PHP优秀框架，但是它是在apache服务器下开发的，在nginx下需要特别的配置才可以使用。

对nginx的配置如下：

 1 server {
 2     listen 80 default_server;
 3     listen [::]:80 default_server ipv6only=on;
 4
 5     root /home/mqx/openflow/openflow/openflow/web;
 6     index index.html index.htm index.php;
 7
 8     server_name localhost;
 9
10     location ~* \.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$ {
11         expires max;
12         log_not_found off;
13     }
14
15
16     location / {
17         try_files $uri $uri/ /index.php;
18         #try_files $uri $uri/ =404;
19     }
20
21     error_page 500 502 503 504 /50x.html;
22     location = /50x.html {
23         root /usr/share/nginx/html;
24     }
25
26     location ~ \.php$
27     {
28
29    　　　fastcgi_pass 127.0.0.1:9000;
30         fastcgi_index index.php;
31         fastcgi_param   PATH_INFO      $fastcgi_path_info;
32         fastcgi_param    SCRIPT_FILENAME    /home/mqx/openflow/openflow/openflow/web$fastcgi_script_name;
33         fastcgi_param    PATH_TRANSLATED    /home/mqx/openflow/openflow/openflow/web$fastcgi_path_info;
34         include fastcgi_params;
35     }
36
37     location ~ /\.ht {
38         deny all;
39     }
40 }
