Nginx rewrite rewrite rules and anti-theft chain configuration method Tutorial Detailed _nginx

Introduction: Nginx rewrite rewrite rules and anti-theft chain configuration method, rewrite rule format flag tags in several forms, hotlinking return 403 error, allow the domain name directly following the second row of the domain name.

Nginx rewrite rewrite rules and anti-theft chain configuration methods are as follows:

Nginx Rewite Rules, official documents: Http://wiki.nginx.org/NginxHttpRewriteModule

Nginx rewrite rule format: rewrite regex replacement flag

Flag tags are available in four different formats:

last– is equivalent to L in Apache.
break– abort Rewirte, do not continue to match
redirect– returns the temporarily redirected HTTP status 302, equivalent to the R in Apache
permanent– returns HTTP status 301 for permanent redirection, equivalent to r=301 in Apache

Can be placed in the server, location, and if modules.

Match judgment:

~ to match case sensitivity;!~ does not match case sensitivity
~* matches case-insensitive;!~ does not match case insensitive

For example, the setting Nginx is redirected to the/nginx-ie directory using the user's use of IE:

if ($http _user_agent ~ msie) {
rewrite ^ (. *) $/msie/$1 break;
}

Attached, common nginx Rewrite rule configuration code.

1, only use a Web site, such as the main website set to www.xfcodes.com.

if ($host!= ' www.xfcodes.com ') {
rewrite ^/(. *) $ http://www.xfcodes.com/$1 permanent;
}

When you access xfcodes.com, you automatically jump to www.xfcodes.com.

2, anti-theft chain

Location ~*. (gif|jpg|png|swf|flv) $ {
Valid_referers none blocked xfcodes.com dgjs123.com;
if ($invalid _referer) {return
403
}}

The hotlinking returns 403 errors, allowing the domain name to be followed directly by the domain name of the second row.

3, the rewrite of WordPress

Location/{
index index.html index.php;
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;
}
}

Currently, this code is used in the Code collection.
