编写SQL语句，把mysql数据组合成Redis协议数据流
SELECT CONCAT( "*16\r\n", \'$\', LENGTH(redis_cmd), \'\r\n\',redis_cmd, \'\r\n\',\'$\', LENGTH(redis_key), \'\r\n\',redis_key, \'\r\n\', \'$\', LENGTH(hkey1), \'\r\n\',hkey1, \'\r\n\',\'$\', LENGTH(hval1), \'\r\n\', hval1, \'\r\n\' \'$\', LENGTH(hkey2), \'\r\n\',hkey2, \'\r\n\',\'$\', LENGTH(hval2), \'\r\n\', hval2, \'\r\n\' \'$\', LENGTH(hkey3), \'\r\n\',hkey3, \'\r\n\',\'$\', LENGTH(hval3), \'\r\n\', hval3, \'\r\n\' \'$\', LENGTH(hkey4), \'\r\n\',hkey4, \'\r\n\',\'$\', LENGTH(hval4), \'\r\n\', hval4, \'\r\n\' \'$\', LENGTH(hkey5), \'\r\n\',hkey5, \'\r\n\',\'$\', LENGTH(hval5), \'\r\n\', hval5, \'\r\n\' \'$\', LENGTH(hkey6), \'\r\n\',hkey6, \'\r\n\',\'$\', LENGTH(hval6), \'\r\n\', hval6, \'\r\n\' \'$\', LENGTH(hkey7), \'\r\n\',hkey7, \'\r\n\',\'$\', LENGTH(hval7), \'\r\n\', hval7, \'\r\' ) FROM ( SELECT \'HMSET\' AS redis_cmd, CONCAT(resource_id,\'_hash\') AS redis_key, \'name\' AS hkey1,resource_title AS hval1, \'type\' AS hkey2,resource_type_name AS hval2, \'exe\' AS hkey3,resource_format AS hval3, \'page\' AS hkey4,resource_page AS hval4, \'size\' AS hkey5,resource_size AS hval5, \'time\' AS hkey6,create_time AS hval6, \'num\' AS hkey7,resource_downcount AS hval7 FROM t_resource_info ) AS t
拼出来的串
*16\r\n$5\r\nHMSET\r\n$9\r\nNBA231058\r\n$4\r\nname\r\n$51\r\n绿色食品的定义及绿色食品标志的使用\r\n$4\r\ntype\r\n$6\r\n文本\r\n$3\r\nexe\r\n$3\r\ndoc\r\n$4\r\npage\r\n$1\r\n1\r\n$4\r\nsize\r\n$6\r\n79.5KB\r\n$4\r\ntime\r\n$19\r\n2013-05-31 08:56:59\r\n$3\r\nnum\r\n$2\r\n18\r\n
执行下面的语句
mysql -h 10.10.3.218 -uroot -p123456 -Dtest_db --skip-column-names --raw </usr/local/redis.sql |redis-cli --pipe
–raw: 使mysql不转换字段值中的换行符。
–skip-column-names: 使mysql输出的每行中不包含列名。
单独执行
echo -en \'*3\r\n$3\r\nSET\r\n$3\r\nkey\r\n$5\r\nvalue\r\n\' | redis-cli --pipe
经测试200W条数据，2分钟以内就可以完成。
