After Searching I found ---
Your last error is "ERR unknown command 'cluster'" – The command is unknown,
and this error only happens on older Redis versions.
But My question is how to achieve this in Redis server version 2.2.12 or above
using GOLANG,
IN python it is working fine
def getRedisConnection(self):
import redis # @UnresolvedImport
if not self.conn:
//self.params ---- {'host': '127.0.0.1', 'port': 6379}
self.conn = redis.Redis(**self.params)
return self.conn
conn = self.getRedisConnection()
info = conn.info()
