Solve the problem that Yii sometimes gets no redis data

Reason: Related to the database configuration parameters of the Yii Redis

Array (

    "Framework.vendors.yiiredis.ARedisConnection",
    "127.0.0.1",
    = 6379,
    = 0,
    "",
    "", "
)

Under Redis, a database is identified by an integer index, not by a database name. By default, one client connects to database 0.

The following parameters in the Redis configuration file control the total number of databases:
databases 16

Conclusion: If the database configuration is different, you will not get the data of other database
