Azure Redis Cache + WordPress On Azure

Question

I've followed the instructions in this post to configure this but redis status is always showing not connected. I tried to turn on diagnostics on redis cache instance but it doesn't even seem like any requests are getting to the service itself. Any ideas?

Answer 1

After some more investigation it looks like there is a thread that covers the majority of the scenarios on the plug in discussions page... I would read through this and ensure you have things in the properly place as well...

Answer 2

HTTPS is not supported by the predis library, you must use the non HTTPS endpoint which is 6379.

Answer 3

you can use https for redis cache and wordpress. You need to set it to set WP_REDIS_SCHEME to use TLS. See: https://cloud.accigo.se/blog/how-to-set-up-azure-redis-cache-for-wordpress/

Answer 4

Sometimes after editing the wp-config.php file, when you click on diagnostics, it will show you Redis: not found, but you may need to wait a little and try to Enable Redis object and disable Redis Object few time to get the updated information from the wp-config file.

I have put together a blog post which list down detailed steps to configure Redis Cache with WordPress on Azure.

I hope this will help.
