Redis-shake 快速体验

1、下载安装redis-shake

wget https://github.com/alibaba/RedisShake/releases/download/v3.0.0/redis-shake-v3.0.0.tar.gz
mv redis-shake-linux-amd64 /usr/local/bin/redis-shake

2、使用容器部署两个Redis测试实例

docker run -d --name redis-4.0.14 -p 6379:6379 redis:4.0.14
docker run -d --name redis-6.0.16 -p 6380:6379 redis:6.0.16

3、源端创建测试数据

[root@redis ~]# docker exec -it redis-4.0.14 redis-cli -h localhost SET key1 value1
OK

4、创建迁移配置文件

完整示例配置文件参考：https://github.com/alibaba/RedisShake/blob/v3/redis-shake.toml

cat >redis-shake.toml<<EOF
[source]
type = "sync"
address = "localhos:6379"

[target]
type = "standalone"
address = "localhos:6380"
EOF

带有用户名密码认证信息的示例配置文件：

[source]
type = "sync"
address = "r-aaaaa.redis.zhangbei.rds.aliyuncs.com:6379"
password = "r-aaaaa:xxxxx"

[target]
type = "standalone"
address = "r-bbbbb.redis.zhangbei.rds.aliyuncs.com:6379"
password = "r-bbbbb:xxxxx"

目标端是redis-cluster的示例配置文件

[source]
type = "sync"
address = "r-aaaaa.redis.zhangbei.rds.aliyuncs.com:6379"
password = "r-aaaaa:xxxxx"

[target]
type = "cluster"
address = "192.168.0.1:6379" # 这里写集群中的任意一个节点的地址即可
password = "r-ccccc:xxxxx"

5、执行redis数据库迁移

6、验证迁移结果

[root@redis ~]# docker exec -it redis-6.0.16 redis-cli -h localhost GET key1
"value1"
