1. 迁移工具
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

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：
