运行 redis 集群到集群直接的实时迁移

redis-migrate-tool -c braavos.conf -n -o log -d

集群到集群直接的实时迁移配置文件

$ vim rmt.conf

[source]

type: redis cluster

servers:

- 10.16.76.65:10044

[target]

type: redis cluster

servers:

- 10.16.76.141:6380

[common]

listen: 0.0.0.0:8888

注意：

1，实时迁移会在源库和目标库之间  互相同步数据  ，这就要求我们需要指定参数 使得源库到目标库的同步是单向的 ，需要加参数  -n, --noreply          : don't receive the target redis reply

2，同步完以后，切换连接后，删除该同步进程，同步即结束
