Today, I would like to share with you how Nginx customizes the relevant knowledge points of the dedicated 404 page, the content is detailed, the logic is clear, I believe most people still know too much about this knowledge, so share this article for your reference, I hope you can get something after reading this article, let's take a look at it.

The first: Nginx's own error page

Nginx visits a static html page, and when the page is not available, Nginx throws 404, so how do you return it to the client?

Take a look at the configuration below, in which case you don't need to modify any parameters to achieve this function.

Server {listen 80th serverpage name www.test.com;root / var/www/test;index index.html index.htm;location / {} # defines the error page number, and if the corresponding error page number occurs, forward it there. Error_page 404, 403, 500, 502, 503, 504 / 404. Htmlwitt # inherits the above location. Location = / 404.html {# the directory path where the error page is placed. Root / usr/share/nginx/html;}} the second kind: error page of reverse proxy

If the backend Tomcat process throws a 404 error, and you want to call Nginx to feedback this status to the client or redirect to a connection, configure as follows:

Upstream www {server 192.168.1.201 server 7777 weight=20 max_fails=2 fail_timeout=30s;ip_hash;} server {listen 80th serveraccounname www.test.com;root / var/www/test;index index.html index.htm;location / {if ($request_uri ~ *'^ / $') {rewrite. * http://www.test.com/index.html redirect } # key parameters: only when this variable is enabled can we customize the error page. When the backend returns 404 http://www;proxy_set_header Nginx intercept error definition error page proxy_intercept_errors on;proxy_pass http://www;proxy_set_header HOST $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-FOR $proxy_add_x_forwarded_for;} error_page 404 / 404.html Location = / 404.html {root / usr/share/nginx/html;}} third: Nginx parses the error page of the php code

If the backend is parsed by php, you need to add a variable

Just add a variable fastcgi_intercept_errors on to the http section.

Specify an error page:

Error_page 404 / 404. Usr/share/nginx/html; location = / 404.html {root / usr/share/nginx/html;} specify a url address: error_page 404 / 404. Htmlownership page 404 = http://www.test.com/error.html; is all the content of the article "how to customize the dedicated 404 page of Nginx". Thank you for reading!
