How do you verify a Redis installation is working correctly?
There are various commands we can use to confirm if redis is working properly.
redis-cli ping # Returns PONG
redis-cli set foo bar # Returns OK
redis-cli get foo # Returns "bar"
redis-cli info server # Shows version, OS, uptime
redis-cli info memory # Shows memory usage
redis-cli debug sleep 0 # Tests event loop responsiveness
For a health check in scripts: redis-cli ping | grep -q PONG && echo "healthy".
