Redis has 16 databases indexed 0 - 15. The default database index is <code>0</code>, so when you run redis commands without specifying the database index, you're only running commands against database index <code>0</code>. However, as of Laravel 5.7, Laravel stores all the cache data in database index <code>1</code>.

In order to see the keys in your cache database, you need to query database <code>1</code>. You can either use the <code>-n</code> switch on the command line to specify the database index, or use the <code>select</code> command at the redis prompt to change the active database.

<pre><code>redis-cli -n 1 keys "*"
</code></pre>

or

<pre><code>#&gt; redis-cli
127.0.0.1:6379&gt; select 1
127.0.0.1:6379[1]&gt; keys *
</code></pre>

<h2>Update</h2>
This may have to do with Laravel cache prefixes in the redis block in the database.php config file. See <a href="https://laravel.com/docs/8.x/redis#configuration" rel="nofollow noreferrer">here</a>
See <a href="https://stackoverflow.com/a/66139722/9530790">this</a> answer for addtional details.
<h2>Previous Ans.</h2>
I had the same issue and I tried the accepted <a href="https://stackoverflow.com/a/56569380/9530790">ans.</a>, however different databases was not the issue.
I was able to find the missing key using <a href="https://redis.io/commands/scan" rel="nofollow noreferrer">scan</a>, like this <code>Redis::scan('*')</code>. Why using <code>Redis::keys('*')</code> is not returning the key, is still a mystery.
(To note only key:values created using Python were not returned with <code>keys</code>, those created with Laravel were.)

I'm using Laravel Cache facade, and the <code>CACHE_DRIVER=redis</code>. All data is saved in Redis successfully, but when I use <code>redis-cli</code> and run <code>keys*</code> there are not keys!

When using the command <code>flushall in redis-cli</code> it loads the data again from the database, so that means the keys are already stored in Redis.

 我使用的是Laravel Cache facade和CACHE_DRIVER=redis。所有数据都成功地保存在Redis中，但是当我使用redis-cli并运行keys*时，却没有密钥！ 当使用flushall in redis-cli命令时，它会再次从数据库加载数据，因此这意味着密钥已经存储在Redis中。
