本文实例讲述了php实现redis数据库指定库号迁移的方法,分享给大家供大家参考。具体如下：

redis普通的数据库迁移,只能整个redis save,或者利用主从,当然也可以安装一个redis-dump,不过比较麻烦,这里提供一种php的脚本,实现指定库号的迁移,其实也就是遍历根据存储类型,读出来,插入新库,效果是这样:复制代码 代码如下:[root@localhost ~]# php 1.php 1/407 101/407 201/407 301/407 401/407PHP实例代码如下:复制代码 代码如下:<?php $from = "10.0.2.52:6379/7"; $to   = "127.0.0.1:6379/7"; $from_redis = redis_init($from); $to_redis   = redis_init($to); $keys  = $from_redis->keys("*"); $count = 0; $total = count($keys); foreach($keys as $key){     if(++$count % 100 == 1){         echo "$count/$total";     }     $type = $from_redis->type($key);     switch($type){         case Redis::REDIS_STRING:             $val = $from_redis->get($key);             $to_redis->set($key, $val);             break;         case Redis::REDIS_LIST:             $list = $from_redis->lRange($key, 0, -1);             foreach($list as $val){                 $to_redis->rPush($key, $val);             }             break;         case Redis::REDIS_HASH:             $hash = $from_redis->hGetAll($key);             $to_redis->hMSet($key, $hash);             break;         case Redis::REDIS_ZSET:             $zset = $from_redis->zRange($key, 0, -1, true);             foreach($zset as $val=>$score){                 $to_redis->zAdd($key, $score, $val);             }             break;     } } function redis_init($conf){     $redis = new Redis();     preg_match("/^([^:]+)(:[0-9]+)?\/(.+)?/", $conf, $ms);     $host = $ms[1];     $port = trim($ms[2], ":");     $db = $ms[3];     $redis->connect($host, $port);     $redis->select($db);     return $redis; } ?>

希望本文所述对大家的php程序设计有所帮助。
