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

REDIS CLI COMMANDS

> 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

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://pass[email protected]:6379

command if username is also provided user123

redis-cli -u redis://user123:[email protected]:6379

This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage

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.
