nginx如何隐藏index.php

我用下面的代码实现隐藏php框架的index.php的目的，但是效果可以了，就是如果把网站首页由index.php换成index.html后，刷新网站首页，由于index.php不存在了，就会出现找不到页面的错误。怎么设置让.html .htm文件不要转向index.php呢，就是说当首页是index.php时自动隐藏转向，如果是index.html .htm之类的页面，就不要转向了呢。

server

{
    listen 80;
    #listen [::]:80;
    server_name www.abcword.com abcword.com;
    index index.html index.htm index.php default.html default.htm default.php;
    root  /home/wwwroot/www.abcword.com;

    *if (-f $request_filename/index.php){
           rewrite (.*) $1/index.php;
    }
    if (!-f $request_filename){
            rewrite (.*) /index.php;
     }*

    include other.conf;
    #error_page   404   /404.html;
    location ~ [^/]\.php(/|$)
    {
        # comment try_files $uri =404; to enable pathinfo
        try_files $uri =404;
        fastcgi_pass  unix:/tmp/php-cgi.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
        #include pathinfo.conf;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
    }

    access_log  /home/wwwlogs/www.abcword.com.log  access;
}

location /
{
        if (!-e $request_filename) {
                rewrite ^(.*)$ /index.php/$1 last;
                break;
        }
}

是这个样么？

请问下面的slim nginx配置示例是什么意思，9000那个端口又是什么意思。http://docs.slimframework.com/routing/rewrite/#nginx

server {

listen       80;
server_name  www.mysite.com mysite.com;
root         /path/www.mysite.com/public_html;

try_files $uri /index.php;

# this will only pass index.php to the fastcgi process which is generally safer but
# assumes the whole site is run via Slim.
location /index.php {
    fastcgi_connect_timeout 3s;     # default of 60s is just too long
    fastcgi_read_timeout 10s;       # default of 60s is just too long
    include fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;    # assumes you are running php-fpm locally on port 9000
}

}
