ngx_cache_purge is nginx module which adds ability to purge content from
FastCGI, proxy, SCGI and uWSGI caches.
Work on the original patch was fully funded by yo.se.
This module is production-ready.
- Clone this repository just outside of the Nginx repo directory
git clone https://github.com/Danrancan/ngx_cache_purge_dynamic.git
- Install build Essentials and Libraries
sudo apt update && sudo apt-get install build-essential libpcre3-dev libssl-dev zlib1g-dev libxml2-dev libxslt1-dev libgd-dev libgeoip-dev
- Get your current configure arguments with
nginx -V - Navigate to your Nginx build directory and execute:
sudo ./configure --add-dynamic-module=../ngx_cache_purge_dynamic --with-compat --the-rest-of-your-configure-arguements
NOTE: Be sure to add the rest of the configure arguments from the output of nginx -V to the ./configure line above.
- Make modules
sudo make modules
Your newly built module will be in objs/ngx_http_cache_purge_module.so
- Move it to /etc/nginx/modules/
sudo mv objs/ngx_http_cache_purge_module.so /etc/nginx/modules/
- Enable Nginx Cache Purge Module
sudo nano /etc/nginx/nginx.conf
- Add the line
load_module modules/ngx_http_cache_purge_module.so;to the top of your nginx.conf file.
user www-data www-data;
worker_processes auto;
pid /run/nginx.pid;
load_module modules/ngx_http_cache_purge_module.so;
http {
- Restart nginx
sudo service nginx restart
ALL DONE!
