Hello @sns1sns
Thank you for your inquiry and I am happy to assist you with this.
Yes in order to be able to use Redis/memcached as a caching method in W3 Total Cache you need to install PHPredis extension and PHP memcached.
Everything is explained in the provided links so please follow the instructions.
Make sure to restart the server once the installation is completed.
Thank you!
Hello,
I have installed redis, memcached and varnish. W3 Total cache has detected Redis and memcached. there were some errors in installing memcached still it has been detected.
I want to know how can i check and verify that memcached, redis and varnish are working right and correctly for the website actively. how to check or test their functionality. and there is no detection system for varnish!!
Hello @sns1sns
Glad to know you managed to install those modules.
As for Redis and Memcached, there is a test button in the option you enabled to use it with. For example, Performance>Object Cache, if selected Redis there is a button to test after you enter the configuration.
Later you can use The debug in Performance>General settings>Debug and enable E.G. Object Cache and you will see the HTML output when inspecting the source.
In Performance>General settings>Reverse Proxy, you only need to check the Enable reverse proxy caching via varnish box and Specify the IP addresses of your varnish instances in Varnish servers: filed. The Varnish configuration language and Access control list must allow this request.
Thank you!
