The role of index Try_files location These three configuration items in Nginx

has been in Meng Nginx routing configuration, after a few hours today's efforts to finally understand.

If there is a wrong place, I hope that the predecessors pointed out the wrong, let me a higher level, but also let me not to go the wrong way farther.

1.index

My understanding is the default path, which is when a file cannot be found with a default path that can be configured multiple.

The specific usage later says, please remember this thing first when you can not find the other suitable thing, the default assigns to you.

2.location

This thing matches the path you need.

Server {
        Listen
      server_name localhost


        root html/
        index index.html index.htm index.php;
        location/{
            try_files $uri $uri//index.php? $a RGs
            Proxy_pass http://www.baidu.com;
       }
        location ~ \. (html|htm) $ {
            try_files $uri = 404
       }


        Location ~ \.php$ {
            Try_files $uri = 404;< br>             include fastcgi.conf;
            Fastcgi_pass 127.0.0.1:9000;
       }
   }

You can match all the URIs you need.

Want to be specific about it. Http://www.nginx.cn/115.html

3.try_files

This thing is redirected, and I feel like index, but it works better than index.

As an example:

Visit: XF.COM/AA

If we set this up, the understanding of this sentence is.

Try_files $uri $uri//index.php $args;

When Nginx receives your XF.COM/AA, it will match up to

Location/{
Try_files $uri $uri//index.php $args;
Proxy_pass http://www.baidu.com;
}

Here is a mouth, if there is no suitable match, then will find the value of index.

Index.html inde.htm index.php

When the corresponding file is found, your access URL will be changed to.

xf.com/index.html or xf.com/index.htm xf.com/index.php one of them.

You understand the index this time?

Come back, we'll talk try_files.

When this is matched, the try_files is executed.

Nginx go back to find out if there's a AA this file ($uri) if not

Continue to find a AA this directory ($uri/) if not, then directly

Redirect to/index.php? $args

$args is your URL, the argument behind the question mark.

Summarize:

Nginx Get to URL

1. Find server_name

2. Find Locationpipei

If the index default file is not found

If not directly 404

Some words plus the default index.* to find a matching location

If there is entry into the executive Try_files

3. Find out if Try_files has the appropriate file

If the last item is not directly redirected
