其實也是很簡單的方法，修改nginx.conf文件，加入以下內容：

代碼如下:
location / {
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}

重啟nginx就可以了。

以下是我的配置文件實例：

www# cat nginx.conf

user  www www;
worker_processes  10;

#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;

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   /usr/local/www/nginx;
index  index.php index.html index.htm;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}

}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   /usr/local/www/nginx-dist;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#location ~ /.php$ {
#    proxy_pass   http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ /.php$ {

fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  /usr/local/www/nginx$fastcgi_script_name;
include        fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
