RediSearch module not loaded!

Use the steps from here to install -> https://redislabs.com/blog/getting-started-with-redisearch-2-0/

Only like this worked for me to install and make it work with redis cache.

Make sure you have in your wp-config file the defines for redis cache.

Thanks Alpha,

I’ve installed the module and tested with command line, it worked. But I don’t have connection with the plugin:

I’ve tried this in wp-config:
define(‘WP_REDIS_HOST’, ‘127.0.0.1’); #Is localhost
define(‘WP_REDIS_PORT’, ‘6379’); #Stardart port
define(‘WP_REDIS_PASSWORD’, ”); #I think I don’t have password (I have other redis app without password and working
define(‘WP_REDIS_INDEX_NAME’, ‘Psicosol’); #I Simple put the name of the site, is that correct?
define(‘WP_REDIS_SCHEME’, ‘tcp’);`

And tried to put in the Redis server configurations in plugin page.

I don’t think is configuration problem because when is put wrong configuration the message change for: “Something went wrong while conencting to Redis Server! go to settings”

Hi @osni-passos,
Which version of Redis and RediSearch do you have? The new versions of this plugin only work with RediSearch 2.0 and above.

While you are testing via the command line, it works regardless of the RediSearch module version. But since versions 2.0 and 1.0 are totally different, I have to check only for the presence of 2.0.

Something like this:

127.0.0.1:6379> module list
1) 1) "name"
   2) "search"
   3) "ver"
   4) (integer) 999999

As for configuration, you don’t need to have configurations in both wp-config.php and plugin settings page. Only one is neccesary.

Thanks for response foadyousefi! You Discovered the problem.

Redis: 4.0.9

I used the apt-get to install redis: sudo apt-get install redis-redisearch
Is the version 1.0.8-1

The version 2.0 work with Redis 4.0.9? Where I find the 2.0 in apt-get?

I’m happy the issue was this easy to spot.

I think RediSearch 2.0 is only working with Redis 6.0 and above.

To install Redis server follow: https://redis.io/topics/quickstart
and RediSearch: https://oss.redislabs.com/redisearch/Quick_Start/

I’m not sure if they are available in apt repository.

Perfect! I’ll look forward on this.

Hi! I’ve also the redisearch.so compiled from source, but I don’t know how to load it into redis. If I call it from command line like this:

redis-server –loadmodule /path/to/module/src/redisearch.so

it works fine, but not as a service. How can I put the module to be loaded with the redis service?

@fidoboy it’s the redis 6.0?

Yes, it’s
