Unable to load redis module, Redis JSON… here is a solution to the problem.
Unable to load redis module, Redis JSON
After following the specified instructions here Compile the source code of RedisJson, get the rejson.so file in project_root/target/release, and then I enter the command sudo redis-server –loadmodule/home/username/RedisJSON/target/release/rejson.so to load the redis module. But I got this error message.
Server initialized

To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

How can I solve this problem?
Solution
Redis JSON requires Redis 6+, and it looks like you’re running an older version of Redis.
