NGINX configuration 404 error page redirection

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 Returns Error Code 404. The corresponding page is the 404 page. 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

Nginx

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

There have been a lot of articles about the experience of customizing the 404 page under IIS and APACHE, and NGINX is still relatively small. Coincidentally, some of my servers are NGINX, in order to solve their own problems, we have made in-depth research on this. 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 the secret 404.html page
2. Change nginx. conf and add it to the http definition area:

fastcgi_intercept_errors on;

3. Add nginx. conf in the server region:

error_page 404 = /404.html

4. Verify nginx. conf:

/usr/local/nginx/sbin/nginx –t

If the information is correct, the following information should be displayed:

the configuration file /usr/local/nginx/conf/nginx.conf syntax is okconfiguration file /usr/local/nginx/conf/nginx.conf test is successful

5. Restart nginx

kill -HUP `cat /usr/local/nginx/nginx.pid `

Configuration file instance:
......

Error_page 500 502 503 504 =/50x.html; ocation =/50x.html {root html ;} log_format webarch.org '$ remote_addr-$ remote_user [$ time_local] "$ request" ''$ status $ response" $ http_referer "'' "$ http_user_agent" $ http_x_forwarded_for '; access_log/usr/local/nginx/logs/webarch.org. log webarch.org ;}......

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 pages. Only when 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 error_page is set correctly (including syntax and corresponding 404 page. do not set the homepage as a 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 ). Use the following two addresses that do not exist for access:

The http://www.webarch.org/no will invoke the self-defined 404.html

Http://www.webarch.org/notfound:
