This article will explain in detail how to set up a custom 503 error page in web. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

What is the 503 status code?

503 Service Unavailable means that the server is currently unable to process requests due to temporary server maintenance or overload. This situation is temporary and will recover after a period of time. If the delay time can be predicted, a Retry-After header can be included in the response to indicate the delay time. If this Retry-After information is not given, the client should handle it in the same way as the 500 response. However, it is worth pointing out that the existence of the 503 status code does not mean that the server must use it when it is overloaded. Some servers just want to deny the connection to the client.

Second, what is the function of the 503 error page?

503 error pages are generally used in the case of website server overload, website function upgrade, network failure, etc. The creation of 503 error page is mainly to tell the search engine that the website is temporarily closed, that a page cannot be accessed temporarily, and that the spider will crawl it again after a period of time, so as not to return the 404 status code and delete the page.

Third, how to make 503 error pages?

In fact, it is also very easy to make 503 error pages. Here we take Breaking Jun blog as an example to show how to make 503 error pages. The specific steps are as follows:

(1) create a 503.php file under the root of the website.

(2) add the following code to the created file:

| | individual original independent blog to share personal interests and interests |

To all visitors.

The blogger went with her sister, and the website is under maintenance.

It is expected to resume on 2013-07-10.

(3) set Nginx rewrite rules to temporarily jump all pages 302to 503.php

Rewrite ^ (. *) $/ 503.php redirect

IV. matters needing attention

When the server or website maintenance can work properly, be sure to restore the previous 302 jump settings and 503 settings, otherwise jump all the way to this page, so that visitors and spiders can not access normally, then the loss will outweigh the gain.
