nginx location configuration instructions

The Location directive in Nginx is an important directive in NginxHttpCoreModule. The Location directive is used to configure the matching URI. The URI is the "/uri/" in the syntax, which can be a string or a regular expression. But if you want to use regular expressions, you must specify a prefix.

nginx location syntax

Basic syntax: location [=|~|~*|^~] /uri/ { … }

= strict match. If this query matches, the search is stopped and the request is processed immediately.
~ is case-sensitive matching (regular expressions are available)
~* is case-insensitive matching (regular expressions are available)
!~ and !~* are case-sensitive mismatching and case-insensitive mismatching respectively
^~ If used with a regular string, this tells nginx not to test the regular expression if the path matches.

Location syntax syntax: location [=|~|~*|^~] /uri/ { … }
Note:
1, ~ are case-sensitive matching
2, ~* are case-insensitive matching
3, !~ and !~* are case-sensitive mismatch and case-insensitive mismatch respectively.

Example 1:

location / { }

matches any query because all requests start with /. But regular expression rules will be prioritized for query matching.

Example 2:

The code is as follows	Copy code
location =/ {}

Only matches /

Example 3:

	Copy code
location ~* .(gif|jpg|jpeg)$ ｛ rewrite .(gif|jpg)$ /logo.png; ｝

Note: Matches anything starting with gif, jpg, The file ending in jpeg

nginx location application example

The code is as follows

Copy the code

location = / { # Only matches / query. }location / { # Matches any query since all requests start with /. But regular expression rules and long block rules will be prioritized and matched against the query. }location ^~ /images/ { # Match any query starting with /images/ and stop searching. Any regular expression will not be tested. }location ~* .(gif|jpg|jpeg)$ { # Match any request that ends with gif, jpg or jpeg. }location ~* .(gif|jpg|swf)$ { valid_referers none blocked start.igrow.cn sta.igrow.cn; if ($invalid_referer) { #Anti-hotlinks rewrite ^/ http:// $host/logo.png; } } location ~* .(js|css|jpg|jpeg|gif|png|swf)$ { if (-f $request_filename) { #Set expiration time based on file type expires 1h; break; } } location ~* .(txt|doc)${ #Prohibit access to a directory root /data/www/wwwroot/linuxtone/test; deny all; }
