Nginx configuration 404 error page redirection

What is the 404 page?

If a website error occurs or the user attempts to access a page that does not exist, the server returnsCodeThe error message is 404, and the corresponding page is 404. The default content of the 404 page is related to the specific server. If the nginx server is used in the background, the 404 page content is:404 not found

Why do we need to customize the 404 page?

When I encounter the above 404 error page, I think 99% (uninvestigated, estimated data) users will close the page, and users will be quietly lost. If there is a beautiful page at this time to guide the user to where he wants to go, the user will inevitably be retained. Therefore, each website should customize its 404 page.

How to customize the 404 page in nginx

Experience in customizing the 404 page under IIS and ApacheArticleThere have been a lot of nginx, and nginx is still relatively small, so we have made in-depth research to solve our own problems. The research results show that it is feasible to configure a custom 404 page in nginx, and it is very simple, just a few steps:

1.Create a secret 404.html page

2.Change nginx. conf to add in the HTTP definition area:Fastcgi_intercept_errors on;

3.Change nginx. conf (or a separate website configuration file, for example, in nginx->Sites-Enabled site configuration file)

Add in the server area:Error_page 404/404 .htmlOrError_page 404 =Http://www.xxx.com/404.html

4.Restart nginx after modification to test the correctness of nginx. conf:/opt/nginx/sbin/nginx-T

#502 and other errors can be configured in the same way.

Error_page 500 502 503 x.html;

Note:

1. You must add: fastcgi_intercept_errors on. If this token is not set, creating 404.html and configuring error_page does not work. Fastcgi_intercept_errors Syntax: fastcgi_intercept_errors on | off default: fastcgi_intercept_errors off add location: HTTP, server, location by default, nginx does not support custom 404 error page, only this command is set to on, nginx supports 404 error redirection. Note that if fastcgi_intercept_errors on is set, nginx will redirect the 404 error. In nginx, the precondition for 404 error redirection to take effect is that fastcgi_intercept_errors on is set, and the error_page option is set correctly (including syntax and corresponding 404 page)

2. Do not set the homepage as the 404 error page for the purpose of saving time or increasing the homepage weight, or use other methods to jump to the homepage.

3. The custom 404 page must be larger than 512 bytes. Otherwise, the default 404 page of IE may appear. For example, the parameter is set to 404.html and the size is only 11 bytes (the content is 404 error ).
