Redis Session implements a session component using redis as the storage medium.
Redis Session requires redis version 2.6.12 or higher to work properly.
It needs to be configured with a redis yii\redis\Connection that is also configured as an application component. By default it will use the redis application component.
To use redis Session as the session application component, configure the application as follows,
[
'components' => [
'session' => [
'class' => 'yii\redis\Session',
'redis' => [
'hostname' => 'localhost',
'port' => 6379,
'database' => 0,
]
],
],
]
Or if you have configured the redis yii\redis\Connection as an application component, the following is sufficient:
[
'components' => [
'session' => [
'class' => 'yii\redis\Session',
// 'redis' => 'redis' // id of the connection application component
],
],
]

A string prefixed to every cache key so that it is unique. If not set, it will use a prefix generated from \yii\redis\Application::id. You may set this property to be an empty string if you don't want to use key prefix. It is recommended that you explicitly set this property to some static value if the cached data needs to be shared among multiple applications.
public string $keyPrefix = null
The Redis yii\redis\Connection object or the application component ID of the Redis yii\redis\Connection. This can also be an array that is used to create a redis yii\redis\Connection instance in case you do not want do configure redis connection as an application component. After the Session object is created, if you want to change this property, you should only assign it with a Redis yii\redis\Connection object.
