How to restart redis cluster after its all shutdown

[optimi...@163.com]

Dear redis supporter,

I build a redis cluster for example, they are as below:

 127.0.0.1:7000 Master

 127.0.0.1:7001 Master

 127.0.0.1:7002 Master

 127.0.0.1:7003 Slave

 127.0.0.1:7004 Slave

 127.0.0.1:7005 Slave

When I use "./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" command to start them at first time,

they are working but when I close them all and restart again, it shows the following errors.

[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. 

Of course, one solution is to delete three files(appendonly.aof dump.rdb nodes.conf) but all previous data will be lost. I don't think it is viable in the production line.

Would you please give me a good idea or  better solution? Thank you

Best regards,

The nodes.conf file on every node contains all the state required to
bring up the Cluster again.
You should be able to just restart every node and they will connect back
to each known node.

Dear supporter,

As my understanding, I just run redis-server redis.conf to restart the crash node. Right?

Thank you!
