Need to add instructions to run setup_redis before using redis-cli

[ramkumarvs]

Right now when we run yb-ctl create we print the different connect strings, but redis would not work unless we run yb-ctl setup_redis or we need to bundle that into the yb-ctl create call.

If I tried to run redis without running setup redis we would see this error.

➜  yugabyte-1.2.10.0 ./bin/redis-cli -h 127.0.0.1
127.0.0.1:6379> set foo bar
(error) ERR set: Could not open YBTable

I face with this error when i run yb-ctl setup_redis
ValueError: Cannot form yb-admin command without knowing master addresses

@zeinali0 This is likely because you don't already have a cluster set up. You'll need to first run
./bin/yb-ctl create : This will create the yugabyteDB cluster and then run
./bin/yb-ctl setup_redis : This will setup redis in the cluster, enabling you to use the redis cli.

i start masters and tservers manually according to this.
Should i run ./bin/yb-ctl create too?

Update
While every thing is working on YCQL i found --master_addresses= not set in my gflags of tservers.

Manual deployment is an alternative to yb-ctl so you should not use yb-ctl here. You should follow this step in order setup the YEDIS API:

I couldn't find how create 3 cluster on 3 different node wit ./bin/yb-ctl create? I didn't see any where mentioned --master_addresses for this command.
Is it possible? or it's just for local cluster.

@zeinali0 yb-ctl is just for local clusters and uses 127.0.0.1 master address. You cannot setup a true multi-node cluster using yb-ctl.
If you want to use local cluster to try out yugabyteDB and redis, you'll need to do:

./bin/yb-ctl create
./bin/yb-ctl setup_redis

However, if you want a true multi-node cluster, then you can follow the steps in manual deployment:
https://docs.yugabyte.com/latest/deploy/manual-deployment/
Once your cluster is created, you can setup redis API using:
./bin/yb-admin --master_addresses 172.151.17.130:7100,172.151.17.220:7100,172.151.17.140:7100 setup_redis_table
Note: replace the master addresses above with your IPs.

Let me know if you have any further questions.
