1.直接下载编译好的
https://github.com/tair-opensource/RedisShake/releases
2.编辑配置文件

[scan_reader]
cluster = false            # set to true if source is a redis cluster
address = "源服务器:端口"
username = ""              # keep empty if not using ACL
password = "密码"              # keep empty if no authentication is required
tls = false
dbs = []                   # set you want to scan dbs such as [1,5,7], if you don't want to scan all
scan = true                # set to false if you don't want to scan keys
ksn = false                # set to true to enabled Redis keyspace notifications (KSN) subscription
count = 1000                  # number of keys to scan per iteration

[advanced]
rdb_restore_command_behavior = "rewrite"

[redis_writer]
cluster = false            # set to true if target is a redis cluster
address = "目标服务器:端口"
username = ""              # keep empty if not using ACL
password = "密码"              # keep empty if no authentication is required
tls = false
off_reply = false          # turn off the server reply

3.运行
./redis-shake sync.toml(刚才编辑的配置文件)
