Redis Slaveof Command

Redis Server
The Redis Slaveof command can transform the current server into a slave server of the specified server.
If the current server is already a slave server of some master server, executing SLAVEOF host port will cause the current server to stop synchronizing with the old master server, discard the old dataset, and start synchronizing with the new master server.
Additionally, executing the command SLAVEOF NO ONE on a slave server will disable the replication function and transform the slave server back to a master server, without discarding the originally synchronized dataset.
By utilizing the feature that 'SLAVEOF NO ONE does not discard the synchronized dataset', you can use the slave server as a new master server when the master server fails, thereby achieving uninterrupted operation.
Syntax
The basic syntax of the redis Slaveof command is as follows:
redis 127.0.0.1:6379> SLAVEOF host port
Available Version
>= 1.0.0
Return Value
Always returns OK.
Example
