1.安装迁移工具

#1.安装依赖
[root@db02 ~]# yum install -y automake libtool autoconf bzip2

#2.拉取工具
[root@db02 ~]# git clone https://github.com/vipshop/redis-migrate-tool

[root@db02 redis-migrate-tool]# autoreconf -fvi
[root@db02 redis-migrate-tool]# ./configure

2.编写数据迁移脚本

[root@db02 redis-migrate-tool]# vim tocluster.sh

[source]

[target]
type: redis cluster
servers:
 - 172.16.1.51:6379

[root@db03 ~]# vim data.sh 
#!/bin/bash
for i in {1001..2000};do
    redis-cli -c -p 6381 -h 172.16.1.52 set k${i} v${i}
done

[root@db03 ~]# sh data.sh
