FYI.

只使用bash和redis-cli 不使用键(这使用扫描) 在集群模式下工作良好 不是原子

也许您只需要修改大写字符。

scan-match.sh

#!/bin/bash
rcli="/YOUR_PATH/redis-cli" 
default_server="YOUR_SERVER"
default_port="YOUR_PORT"
servers=`$rcli -h $default_server -p $default_port cluster nodes | grep master | awk '{print $2}' | sed 's/:.*//'`
if [ x"$1" == "x" ]; then 
    startswith="DEFAULT_PATTERN"
else
    startswith="$1"
fi
MAX_BUFFER_SIZE=1000
for server in $servers; do 
    cursor=0
    while 
        r=`$rcli -h $server -p $default_port scan $cursor match "$startswith*" count $MAX_BUFFER_SIZE `
        cursor=`echo $r | cut -f 1 -d' '`
        nf=`echo $r | awk '{print NF}'`
        if [ $nf -gt 1 ]; then
            for x in `echo $r | cut -f 1 -d' ' --complement`; do 
                echo $x
            done
        fi
        (( cursor != 0 ))
    do
        :
    done
done

clear-redis-key.sh

#!/bin/bash
STARTSWITH="$1"

RCLI=YOUR_PATH/redis-cli
HOST=YOUR_HOST
PORT=6379
RCMD="$RCLI -h $HOST -p $PORT -c "

./scan-match.sh $STARTSWITH | while read -r KEY ; do
    $RCMD del $KEY 
done

在bash提示符下运行

$ ./clear-redis-key.sh key_head_pattern

对于那些无法解析其他答案的人:

eval "for _,k in ipairs(redis.call('keys','key:*:pattern')) do redis.call('del',k) end" 0

将key:*:pattern替换为您自己的模式，并将其输入到redis-cli中，就可以开始了。

我支持所有与有一些工具或执行Lua表达式相关的答案。

我还有一个选择:

在我们的生产和预生产数据库中，有数千个键。时不时地，我们需要删除一些键(通过一些掩码)，修改一些标准等。当然，没有办法从CLI手动完成，特别是使用分片(每个物理分区中有512个逻辑dbs)。

为此，我编写了一个java客户端工具来完成所有这些工作。在删除键的情况下，实用程序可以非常简单，只有一个类:

public class DataCleaner {

    public static void main(String args[]) {
        String keyPattern = args[0];
        String host = args[1];
        int port = Integer.valueOf(args[2]);
        int dbIndex = Integer.valueOf(args[3]);

        Jedis jedis = new Jedis(host, port);

        int deletedKeysNumber = 0;
        if(dbIndex >= 0){
            deletedKeysNumber += deleteDataFromDB(jedis, keyPattern, dbIndex);
        } else {
            int dbSize = Integer.valueOf(jedis.configGet("databases").get(1));
            for(int i = 0; i < dbSize; i++){
                deletedKeysNumber += deleteDataFromDB(jedis, keyPattern, i);
            }
        }

        if(deletedKeysNumber == 0) {
            System.out.println("There is no keys with key pattern: " + keyPattern + " was found in database with host: " + host);
        }
    }

    private static int deleteDataFromDB(Jedis jedis, String keyPattern, int dbIndex) {
        jedis.select(dbIndex);
        Set<String> keys = jedis.keys(keyPattern);
        for(String key : keys){
            jedis.del(key);
            System.out.println("The key: " + key + " has been deleted from database index: " + dbIndex);
        }

        return keys.size();
    }

}

下面的命令对我很有用。

redis-cli -h redis_host_url KEYS "*abcd*" | xargs redis-cli -h redis_host_url DEL

请使用此命令并尝试:

redis-cli --raw keys "$PATTERN" | xargs redis-cli del

如果你使用windows环境，请遵循以下步骤，它一定会工作:

Download GOW from here - https://github.com/bmatzelle/gow/wiki (because xargs command doesn't works in windows) Download redis-cli for Windows (detailed explanation is here - https://medium.com/@binary10111010/redis-cli-installation-on-windows-684fb6b6ac6b) Run cmd and open directory where redis-cli stores (example: D:\Redis\Redis-x64-3.2.100) if you want to delete all keys which start with "Global:ProviderInfo" execute this query (it's require to change bold parameters (host, port, password, key) and write yours, because of this is only example): redis-cli -h redis.test.com -p 6379 -a redispassword --raw keys "Global:ProviderInfo*" | xargs redis-cli -h redis.test.com -p 6379 -a redispassword del
