recently I could config & install PhpRedis on my dedicated server and im using the Redis cache plugin with my wordpress setup
Nice work bro Thanks a lot ❤️
I also recommend using the Pro version (Object Cache Pro) with more options and better performance
objectcache[DOT]pro
Easy setup

When I was getting to know about object cache and other things, I was worried about spending lots of time setting it up. But I rarely face any error and it was quick. :)
Great plugin

Redis Object Cache works great and really helps speed up my site. But what impressed me the most was the support: super responsive and helpful. Till fixed a compatibility issue almost immediately. Highly recommended!
Good but not good enough

Not recommended, when your REDIS instance on server blows out. This plugin will make your site crash when it's unable to connect. Litespeed build in Object cache storage on the other hand simply disables the Object caching but continues to run the website.

"Error establishing a Redis connection" with dockerized WordPress 6.7.1
By 
cuktrshmls on December 8, 2024
Hello Till,
I’m reaching out regarding an issue we’ve encountered when using the Redis Object Cache plugin with a fresh installation of WordPress 6.7.1. Despite following the official setup guidelines, our WordPress site fails with the following error:
Error establishing a Redis connection
Connection refusedWordPress is unable to establish a connection to Redis. This means that the connection information in your
wp-config.phpfile are incorrect, or that the Redis server is not reachable.
- Is the correct Redis host and port set?
- Is the Redis server running?
If you need help, please read the installation instructions.
To disable Redis, delete the
object-cache.phpfile in the/wp-content/directory.
Here are the details of our setup:
- WordPress Version: 6.7.1 (fresh installation)
- Redis Plugin Version: Redis Object Cache 2.5.4
- Server Environment:
- Dockerized Setup: Using
docker-compose- Relevant Containers:
- WordPress (
wordpress:php8.0-fpm)- Redis (
redis:alpine)- WP-CLI (
custom-wordpress-clibuilt on the official WP-CLI image)- Nginx (
nginx:alpine) for frontend- MariaDB (
mariadb:latest) for the database- Varnish (
varnish:stable) for caching- Redis Configuration:
- Redis is running in the
my-rediscontainer and is reachable from other containers within the Docker bridge network (my_network).- Redis configuration: Default Alpine Redis settings (
bind *,protected-mode no).wp-config.phpConstants for Redis
define("WP_REDIS_HOST", "my-redis");define("WP_REDIS_PORT", 6379);define("WP_REDIS_DATABASE", 0);define("WP_REDIS_DEBUG", true);define("WP_DEBUG", true);define("WP_DEBUG_LOG", true);define("WP_DEBUG_DISPLAY", false);@ini_set("display_errors", 0);define("WP_REDIS_TIMEOUT", 5);define("WP_REDIS_READ_TIMEOUT", 5);- Plugin Behavior:
- Activating the plugin creates the
object-cache.phpdrop-in at/wp-content/.- The Redis server is accessible (
PONGresponse from Redis CLI within the WordPress container).- Enabling Object Cache via the plugin causes the "Error establishing a Redis connection" issue.
Steps we’ve tried:
- Verified network connectivity:
- Pinged
my-redisfrom the WordPress container (ping my-redisworks).- Successfully executed
redis-cli -h my-redis pingfrom the WordPress container (PONGresponse).- Reviewed Redis logs:
- No errors in Redis logs, and
CONFIG GETshows the expected settings (bind,protected-mode, etc.).- Tested Redis connectivity from WP-CLI:
- WP-CLI reports Redis as reachable, but enabling Object Cache causes the same error.
- Tried replacing the
object-cache.phpfile:
- Replaced it with the latest version from the plugin's GitHub repository (branch:
develop).- Reinstalled the plugin:
- Deactivated, uninstalled, and reinstalled the Redis Object Cache plugin. The error persisted.
- Checked for known compatibility issues:
- Verified that Redis Object Cache 2.5.4 supports Redis 7.4.1 and PHP 8.0.
Summary of issue
- Redis is reachable and functional, yet WordPress fails to connect when Object Cache is enabled.
- The error specifically points to
RedisException: Connection refusedin/wp-content/object-cache.php.- We suspect a compatibility issue between Redis Object Cache and WordPress 6.7.1 but have not found evidence of this in community forums or issue trackers.
Questions:
- Are there known issues with the Redis Object Cache plugin and WordPress 6.7.1 or Redis 7.4.1?
- Could this be related to the
object-cache.phpdrop-in, or should we consider alternative configurations for Redis?- Are there any additional debug steps or alternative plugin versions (e.g., pre-releases) we should test?

Very disappointed with paid version
By 
jussipv on October 26, 2024
I used the free version on my site at first, managed to install it and seemed to work based on what Query Monitor plugin showed. Still wasn't happy with site performance though so I bought the paid version which is said to be "optimized for WooCommerce" and "Rewritten for raw performance".
Well, after paying a monthly fee of $95 (which is normally a yearly license fee for a plugin btw) and installing the pro version following step-by-step guide and the basic settings found from the Docs, Query Monitor showed again that the object cache is working.
The only issue now was that page load times which were 3-4 seconds before in my store became 8-14 seconds long and I started getting complaints from my customers about very slow store. I disabled the plugin and everything went back to normal (3-4 second load times). I was hoping to cut 1-2 seconds off from the 3-4 seconds but it actually tripled the load times...
My server resources never hit a peak above 70% (6 cpus, 16 GB RAM) so it's not having enough resources. It has to be something with the plugin setup.
I contacted "support" of the paid plugin which was a chatbot on their website. Tried asking for help in setting up the plugin because most likely there is something I could do to make it work better, or that's what I thought at least. But paying $95/month I expected to get some help from the developer like has always been the case with any paid WooCommerce plugin from WooCommerce.com. The chatbot said that they will be back "later today" to answer my message. This was October 18th which is 8 days ago. Still to this day I haven't gotten a response.
Well they say "All purchases come with a 14-day, no hassle, 100% money back guarantee." on their website and as I was very disappointed with the plugin and the support, I contacted them again. Through the chatbot because that seems to be the only easily available channel to contact them. I said "Refund" to the chatbot and it said "The team will get back to you on this. Object Cache Pro will be back later today." This is now 2 days ago.
I did find an email to their support from the initial order confirmation email so I sent an email on Thursday (2 days ago) with a high priority to them. No response to that either.
This is what reads on their website as a selling point: "Expert, hands-on help setting up your object cache, and receive a response in as little as 30 minutes from your dedicated engineer via email or Slack."
Here I am 8 days later waiting for that help. You're not waiting for that 14 days money-back guarantee to run out are you?
Anyway I'm taking this up with Stripe now and if they don't help I'll make a report to my bank and they'll make a chargeback which I believe will cost more to the company than just giving me the "hassle-free refund".
And no I am not interested in setting up the plugin anymore. By paying $95/month I expect a response within a week to my support request. I've said within the first 14 days of my purchase that I want a refund so I still expect to get it.
I didn't want to make this public but you kind of left me no choice.
