Cleaning/deletion of items from NGINX Cache

Introduction

As name suggests, nginx-cache-cleaner removes an item or set of items from Nginx cache directory.

It accepts a [grep pattern] as argument to search for cached items in the given cache directory.

The script requires read-write access to the cache directory.

Usage

Method 1

1. Delete index.html from the /data/nginx/cache0 cache.

   nginx-cache-cleaner "index.html" /data/nginx/cache0
   

2. Delete all json files from the /data/nginx/jsoncache cache.

   nginx-cache-cleaner "\.json" /data/nginx/jsoncache 
   

Method 2

If you want to make a scheduled script/worker and make a purging engine. Then you push all the items to purged in a queue(DB/amqp etc) and purge it via purge-nginx-cache.php script.

Here, I have taken a MySQL Queue(table). Just insert the items to be purged in nginx_cache_cleaner_log table and schedule purge-nginx-cache.php script. Also, make changes in entity-cache directory confi before using it.

Installation

1. Clone the repo.

2. Place the script in a convenient place.

3. Execute the scipt as specified above.

4. Done.
