打开 nginx 的配置文件 nginx.conf 文件，修改如下：
01 #
我使用的是虚拟主机配置
02 server {
03
listen 80;
04
server_name
dev.example.com;
05
06
rewrite_log
on;
07
08
root
/www/web/htdocs/dev.example.com;
09
index index.php
index.html index.htm;
10
11
location / {
12
index index.php index.html index.htm;
13
}
14
15 location ~
\.php($|/) {
16
fastcgi_pass 127.0.0.1:9000;
17
fastcgi_index index.php;
18
fastcgi_split_path_info ^(.+\.php)(.*)$; //注1
19
fastcgi_param PATH_INFO $fastcgi_path_info;
20
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
21
include
fastcgi_params;
22
}
23
24 if (!-e
$request_filename) {
25
rewrite
^/(.*)$ /index.php/$1 last;
26
break;
27
}
28
29
location ~ /\.ht
{
30
deny all;
31
}
32 }
注1
****PATH_INFO:
该指令的参数是一个正则表达式分组一标识 $fastcgi_script_name、分组二标识 $fastcgi_path_info（等同于PHP $_SERVER 中的 PATH_INFO）,前提条件是nginx版本大于0.7.31。
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO
$path_info;
官方示例：
location ~ ^.+\.php {
...
fastcgi_split_path_info
^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME
/path/to/php$fastcgi_script_name;
fastcgi_param PATH_INFO
$fastcgi_path_info;
fastcgi_param PATH_TRANSLATED
$document_root$fastcgi_path_info;
...
}
