redis中使用redis-dump导出、导入、还原数据实例（redis 导出数据）居然可以这样

[root@localhost tank]# telnet 127.0.0.1 6379 //telnet到redis 

Trying 127.0.0.1… 

Connected to 127.0.0.1. 

Escape character is ‘^]’. 

flushall //请空所有数据 

+OK 

keys * //查看已清空 

*0 

[root@localhost tank]# < test.json redis-load //导入数据 

[root@localhost tank]# telnet 127.0.0.1 6379 

Trying 127.0.0.1… 

Connected to 127.0.0.1. 

Escape character is ‘^]’. 

keys * //已导入成功
