==在集群中删除多个指定的key ==

<pre>
删除单个的 如下 
 cat redisloop.sh
#!/bin/bash
#模糊删除 key   在re.sh 那个脚本里面
cat  $1  | while read line
do

redis-cli    -c  -h    172.31.22.218   -p 7000  -a hellopass $line
redis-cli    -c  -h    172.31.22.218   -p 7001  -a hellopass  $line
redis-cli    -c  -h   172.31.16.135   -p 7002  -a hellopassw   $line  
redis-cli    -c  -h   172.31.16.135   -p 7003  -a hellopassw  $line
redis-cli    -c  -h   172.31.23.43   -p 7004  -a hellopassw  $line
redis-cli    -c  -h   172.31.23.43   -p 7005  -a hellopassw   $line
</pre>

删除单个：del key

删除多个：redis-cli -a pass(密码) keys "WX_ACT_USER_KEY_*" | xargs redis-cli -a pass(密码) del

$redis_comm -c -h $redis_ser02  -p 7001 -a xxx  keys $1 | xargs -i $redis_comm -c -h $redis_ser02  -p 7001 -a xxx del {}

运行：

./redis_del_key.sh  匹配的key*

err  

-i  {} 都是一定要的 

redis-cli -n 0 keys "test*" | xargs redis-cli -n 0 del
(error) CROSSSLOT Keys in request don't hash to the same slot

=del相关=

命令和DEL十分相似：删除指定的key(s),若key不存在则该key被跳过。但是，相比DEL会产生阻塞，该命令会在另一个线程中回收内存，因此它是非阻塞的。 这也是该命令名字的由来：仅将keys从keyspace元数据中删除，真正的删除会在后续异步操作。
