MySQL向redis同步数据

标签：redis mysql

##创建表及数据

CREATE TABLE events_all_time (

id int(11) unsigned NOT NULL AUTO_INCREMENT,

action varchar(255) NOT NULL,

count int(11) NOT NULL DEFAULT 0,

PRIMARY KEY (id),

UNIQUE KEY uniq_action (action)

);

insert into events_all_time(action,count) values(‘yangdan‘,1000);

insert into events_all_time(action,count) values(‘liufeng‘,200);

##保存同步数据脚本

SELECT CONCAT(

"*4\r\n",

‘$‘, LENGTH(redis_cmd), ‘\r\n‘,

redis_cmd, ‘\r\n‘,

‘$‘, LENGTH(redis_key), ‘\r\n‘,

redis_key, ‘\r\n‘,

‘$‘, LENGTH(hkey), ‘\r\n‘,

hkey, ‘\r\n‘,

‘$‘, LENGTH(hval), ‘\r\n‘,

hval, ‘\r‘

)

FROM (

SELECT

‘HSET‘ as redis_cmd,

‘events_all_time‘ AS redis_key,

action AS hkey,

count AS hval

FROM events_all_time

) AS t;

##执行同步命令（shell）

mysql [-h 127.0.0.1] -uroot -plinuxcast -DtestRedis --skip-column-names --raw </usr/local/events_to_redis.sql |redis-cli --pipe

##登录redis

hgetall events_all_time
