Install Memcached and set up distributed caching with consistent hashing across multiple nodes.

Memcached Distributed Setup on AlmaLinux 9

Memcached itself has no cluster mode — distribution is handled by the client using consistent hashing.

Run multiple instances

memcached -d -l 192.168.1.10 -p 11211 -m 512 -t 4 -u memcache
memcached -d -l 192.168.1.11 -p 11211 -m 512 -t 4 -u memcache
