Workaround:

1) Delete the local backup files such as aof and rdb under the newly added nodes;

2) Delete the cluster configuration file of the new Node at the same time, that is, delete the file where the cluster-config-file is located in your redis.conf;

3), add a new node again If you still report an error, log in to the new Node, ./redis-cli–h x –p to clear the database:

172.168.63.201:7001> flushdb #Clear the current database


After executing the script by 1), 2) or 3) in the above solution, the script is successfully executed;
