How to connect to remote Redis server?
I have URL and PORT of remote Redis server. I am able to write into Redis from Scala. However I want to connect to remote Redis via terminal using redis-server or something similar in order to make several call of hget, get, etc. (I can do it with my locally installed Redis without any problem).
redis-cli -h XXX.XXX.XXX.XXX -p YYYY
xxx.xxx.xxx.xxx is the IP address and yyyy is the port
EXAMPLE from my dev environment
redis-cli -h 10.144.62.3 -p 30000
Host, port, password and database By default redis-cli connects to the server at 127.0.0.1 port 6379. As you can guess, you can easily change this using command line options. To specify a different host name or an IP address, use -h. In order to set a different port, use -p. redis-cli -h redis15.localnet.org -p 6390 ping
In Case of password also we need to pass one more parameter
redis-cli -h host -p port -a password
redis-cli -h host -p port And then authenticate. host:6379> AUTH abcdefg
There are two ways to connect remote redis server using redis-cli:
1. Using host & port individually as options in command
redis-cli -h host -p port
If your instance is password protected
redis-cli -h host -p port -a password
e.g. if my-web.cache.amazonaws.com is the host url and 6379 is the port
Then this will be the command:
redis-cli -h my-web.cache.amazonaws.com -p 6379
if 92.101.91.8 is the host IP address and 6379 is the port:
redis-cli -h 92.101.91.8 -p 6379
command if the instance is protected with password pass123:
redis-cli -h my-web.cache.amazonaws.com -p 6379 -a pass123
2. Using single uri option in command
redis-cli -u redis://password@host:port
command in a single uri form with username & password
redis-cli -u redis://username:password@host:port
e.g. for the same above host - port configuration command would be
redis-cli -u redis://pass123@my-web.cache.amazonaws.com:6379
command if username is also provided user123
redis-cli -u redis://user123:pass123@my-web.cache.amazonaws.com:6379
This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage
redis-cli -u rediss://default:passwd@example-redis.aivencloud.com:25945, it throws Invalid URI scheme error.
redis-cli does not support TLS connections, so you’ll need to use a different tool that supports the rediss protocol in order to connect with the URI. I’ll suggest using redli(github.com/IBM-Cloud/redli) and this command to connect: redli --tls -u rediss://default:passwd@example-redis.aivencloud.com:25945. But if you’re bound to use redis-cli then you’ll be needed to do extra config for the same. Check: redis.io/topics/encryption
redis://user:password@host:port/0
One thing that confused me a little bit with this command is that if redis-cli fails to connect using the passed connection string it will still put you in the redis-cli shell, i.e:
redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>
You'll then need to exit to get yourself out of the shell. I wasn't paying much attention here and kept passing in new redis-cli commands wondering why the command wasn't using my passed connection string.

Could not connect to Redis at -c:6379: Temporary failure in name resolutionredis-cli -u redis://user:pass@host:portas well if you don't feel like entering host and port separately..docker run -it --rm bitnami/redis:latest redis-cli -h host.docker.internal -p 6379should work
