redis 数据迁移（RDB文件-》集群）

1. 迁移工具

github.com/tanruixing8…

另外自己做了一个包含此工具的镜像,可以下载使用

docker pull lyman1567/redis-migrate-tool复制代码

2 迁移数据配置

#rmt.conf[source]type: rdb fileservers: - /usr/local/etc/redis/dump.rdb[target]type: redis clusterservers: - 10.0.0.10:6379[common]listen: 0.0.0.0:8888复制代码

3 准备好后，开始部署

$ docker psCONTAINER ID  IMAGE                                COMMAND                CREATED          STATUS                          PORTS                    NAMESbea2824575f6  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6379->6379/tcp  docker-redis-cluster-605_redis-1_1a3d701b0ec4f  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6382->6379/tcp  docker-redis-cluster-605_redis-4_1075c167803af  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6383->6379/tcp  docker-redis-cluster-605_redis-5_124e69de07e17  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6380->6379/tcp  docker-redis-cluster-605_redis-2_17105bf04fcb7  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6381->6379/tcp  docker-redis-cluster-605_redis-3_1ca51ec501820  redis-cluster-node"/bin/bash /start.sh"39 minutes ago  Up 39 minutes                  0.0.0.0:6384->6379/tcp  docker-redis-cluster-605_redis-6_1$ docker imageslyman1567/redis-migrate-tool  latest    72c4a8146559  11 hours ago    473MB$ docker run -it --network=container:bea2824575f6 --pid=container:bea2824575f6 -v C:/redis-migrate-tool/data:/usr/local/etc lyman1567/redis-migrate-tool bash复制代码

4 进入集群容器执行

[root@bea2824575f6 /]# cd /usr/local/etc[root@bea2824575f6 etc]# lsconf  redis[root@bea2824575f6 etc]# cd conf[root@bea2824575f6 etc]# vi rmt.conf[source]type: rdb fileservers: - /usr/local/etc/redis/dump.rdb[target]type: redis clusterservers: - 10.0.0.10:6379[common]listen: 0.0.0.0:8888复制代码

5 确认好后，执行

[root@bea2824575f6 conf]# redis-migrate-tool -c rmt.conf -o output.log -d复制代码

6 查看log

可以看出来：rdb总用时97秒

7 查看集群数据

redis--port:6379

如果想用两个不同的容器加入同一网络，进行数据迁移可以参考下面博文：
