Using replication is very simple for LedisDB, only using `slaveof` command.

+ Use `slaveof no one` to stop replication and change the slave to master.
If a slave first syncs from a master A, then uses slaveof to sync from master B, it will sync with the LogID = LastLogID + 1. If you want to start over from B, you must first use `slaveof host port restart`.
If a slave first syncs from a master A, then uses `slaveof` to sync from master B, it will sync with the LogID = LastLogID + 1. If you want to start over from B, you must use `slaveof host port restart` which will start a full sync first.
## Limitation
+ Replication can not store log less than current LastLogID.
+ Cycle replication not support.
+ Cycle replication is not supported.
+ Master and slave must set `use_replication` to true to support replication.
