如何使用 Redis-port 导入物理备份 rdb 文件？

问题分析

缓存数据库 Redis 版支持下载备份的 rdb 文件，然后通过 Redis-port 导入到新的实例中

模拟步骤

1.准备测试数据

使用 redis-benchmark 写入不同数据类型的数据

redis-benchmark -h redis-cnl*****.redis.volces.com  -p 6379 -n 1000 -c 20 -a $password -t SET,MSET,LPUSH,HSET,SADD,RPUSH,INCR -r 100

====== SET ======
  1000 requests completed in 0.02 seconds
  20 parallel clients
  3 bytes payload
  keep alive: 1

100.00% <= 0 milliseconds
58823.53 requests per second

====== INCR ======
  1000 requests completed in 0.01 seconds
  20 parallel clients
  3 bytes payload
  keep alive: 1

100.00% <= 0 milliseconds
66666.67 requests per second

……
……



95.00% <= 201 milliseconds
99.60% <= 202 milliseconds
100.00% <= 202 milliseconds
1562.50 requests per second

备份下载

进入火山实例的管控界面，选择备份恢复，手动备份生成最新备份文件（业务低峰操作），或者下载已经备份过的文件。

下载redis-port 工具

下载和解压工具，可直接使用，无需编译。在执行导出和导入操作的服务器上都需要安装 Redis-port。

wget https://github.com/CodisLabs/redis-port/releases/download/v2.0-beta/redis-port-v2.0-beta-go1.10.1-linux.tar.gz
# 解压安装后可以使用
tar -xvf redis-port-v2.0-beta-go1.10.1-linux.tar.gz

数据导入
