codeigniter nginx rewrite规则配置

nginx如何配置才能支持codeigniter ？

1. codeigniter的url美化去掉index.php

        location / {
            root   html/gxtp;
            index  index.php;
            try_files $uri $uri/ /index.php?$uri&$args;
        }
2.与thinkphp一样codeigniter的url rewrite也是使用pathinfo来实现的，需要借助fastcgi_split_path_info来设置$ _SERVER['PATHINFO']。
location ~ ^.+\.php {
include        fastcgi_params;
root           html/gxtp;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
}
codeigniter完整版nginx.conf规则
worker_processes  1;
events {
worker_connections  1024;
}
http {
include       mime.types;
default_type  application/octet-stream;
sendfile        on;
keepalive_timeout  65;
server {
listen       80;
server_name  www.264.cn;
location / {
root   html/kdw;
index  index.php;
try_files $uri $uri/ /index.php?$uri&$args;
}
location ~ ^.+\.php {
include        fastcgi_params;
root           html/kdw;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
}
}
}
