问题
On src directory, i am running below command
/redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
but getting below error.
Creating cluster [ERR] Sorry, can't connect to node 127.0.0.1:7000
However if i am starting the node at 7000 using command "redis-server redis.conf" where redis.conf is below
port 7000 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 10 cluster-slave-validity-factor 0 appendonly yes
and simillarly i started redis in all ports succesfully.
Now when i am running
/redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
i am getting another erorr.
Creating cluster [ERR] Node 127.0.0.1:7000 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.
please help.
回答1:
The first error is because redis-trib create attempts to connect to the redis instances while creating the cluster- however you do not have any redis instances running at 127.0.0.1:7000.
The second error looks like you started your redis instance, but now your cluster cannot be created because you already tried to create a cluster on node 7000 (Probably allocated slots to your node) before you got the first error message. To wipe the node clean, run
$redis-cli -p 7000
127.0.0.1:7000> flushall
127.0.0.1:7000> cluster reset
127.0.0.1:7000> exit
then your redis-trib create will work.
