This article is about how proxy_cache bulk clears caches in nginx. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Previously, using the official nginx proxy_cache as the CDN static cache, it was found that it was a big problem for this module to clean up the cache, which could only be cleared one by one url. For this reason, a script was written to batch clear the cache.

The main features include:

1. Clean up by file typ

two。 Clean up by specific file name

3. Clean up by site directory

Here is the bash shell script code. There have been a lot of similar scripts on the Internet before, but they don't feel good and are easy to mislead people to make mistakes.
