先编写sql脚本，查询好需要导入redis的数据，同时在脚本中设定好redis的类型；最外层的查询需要设定好查询的字段数量，key value各算一个。
我用的是hash结构，将表明以key的形式存储，字段+对应的值以json格式存储，脚本在图片下方
脚本上传到服务器后使用此命令导入数据（用户名密码、脚本路径自行更改）：mysql -uroot -p123456 -h 127.0.0.1 database--skip-column-names --raw <data.sql | /usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 -a mima --pipe
SELECT CONCAT(
"*4

'$', LENGTH(redis_cmd), '

redis_cmd, '

'$', LENGTH(redis_key), '

redis_key, '

'$',LENGTH(hkey),'

FROM(
SELECT
'HSET' AS redis_cmd,
'tab_product' AS redis_key,
a.product_id AS hkey,
CONCAT(

',"address":"', ifnull(e.address,''),'"',
',"businessHours":"', ifnull(e.business_hours,''),'"',

',"productImageList":', ifnull(CONCAT('[',GROUP_CONCAT('{"img":"',b.img, '"}'),']'),''),'}'
) AS hval
FROM `tab_product` a
LEFT JOIN tab_product_image b on a.product_id = b.product_id and b.state = 0
LEFT JOIN tab_product_tag c on c.product_id = a.product_id and c.state = 0
LEFT JOIN tab_tag d on d.id = c.tag_id and d.state = 0
LEFT JOIN shop.tab_shop e on e.shop_id = a.shop_id
group by a.id
) AS t
这是HSET结构，用到的改一下上面的就可以了
