Laravel: how to separate cache and session into different redis database?
提问by Nemo Jia
I want to put session and cache data into redis. This is my configuration in database.php:
我想将会话和缓存数据放入redis。这是我在database.php 中的配置：
'redis' => array(
'cluster' => false,
'default' => array(
'host' => '192.168.56.101',
'port' => 6379,
'database' => 0,
),
'session' => array(
'host' => '192.168.56.101',
'port' => 6379,
'database' => 1,
),
),
session.php:
会话.php：
return array(
'driver' => 'redis',
'connection' => 'session',
);
cache.php:
缓存.php：
'driver' => 'redis',
However, where I write code like this:
但是，我在哪里编写这样的代码：
Cache::remember('aa',1,function(){
return 'bb';
});
cache driver uses the same redis database as session driver does, which results in:
缓存驱动程序使用与会话驱动程序相同的 redis 数据库，这导致：
127.0.0.1:6379[1]> keys *
1) "aa"
2) "e0606244bec40b0352fb2b7b65d98049e49f6189"
Anyone knows how to force cache to use a specific redis connection? Or I have to mix them up together?
任何人都知道如何强制缓存使用特定的 redis 连接？还是我必须把它们混合在一起？

Introduction
介绍
Here is my note, for some other guy who running in to this problem, I think this is should be in the docs.
这是我的笔记，对于遇到此问题的其他人，我认为这应该在文档中。
By default, redis gives you 16 separate databases, but laravel out of the box will try to use database 0 for both sessions and cache.
默认情况下，redis 为您提供 16 个独立的数据库，但开箱即用的 laravel 会尝试将数据库 0 用于会话和缓存。
Our solution is to let Redis caching using database 0, and database 1 for Session, there for solving the session clear by running php artisan cache:clearproblem.
我们的解决方案是让Redis缓存使用数据库0，数据库1用于Session，以解决会话清除运行php artisan cache:clear问题。
Note: Tested at Laravel 5.1
注意：在 Laravel 5.1 测试
1. Setting up Session Redis connection
1.设置Session Redis连接
Modify config/database.php, add sessionkey to the redisoption:
修改config/database.php，session在redis选项中添加key ：
'redis' => [
'cluster' => false,
'default' => [
'host' => env('REDIS_HOST', 'localhost'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
'session' => [
'host' => env('REDIS_HOST', 'localhost'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 1,
],
],
2. Make use of the sessionconnection
2.利用session连接
Modify config/session.php, change the following:
修改config/session.php，更改以下内容：
'connection' => null,
to:
到：
'connection' => 'session',
3. Using Redis as session driver
3. 使用Redis作为会话驱动
Modify .env, change SESSION_DRIVER:
修改.env，改变SESSION_DRIVER：
SESSION_DRIVER=redis
4. Testing out
4. 测试
Execute the following artisan command, then check your login state:
执行以下 artisan 命令，然后检查您的登录状态：
php artisan cache:clear
If the login state persists, voilà!
如果登录状态仍然存在，瞧！

Laravel 5.5:
Laravel 5.5：
database.php should look like this:
database.php 应如下所示：
'redis' => [
'client' => 'predis',
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
'session' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 1,
],
],
And in the session.php you have to update also the key "connection" to the right key. In this case 'session'
在 session.php 中，您还必须将密钥“连接”更新为正确的密钥。在这种情况下“会话”
'connection' => 'session',

Laravel 5now supports this.
Laravel 5现在支持这一点。

You can select redis connection by modifying config/cache.php
可以通过修改选择redis连接 config/cache.php
'stores' => [
'redis' => [
'driver' => 'redis',
'connection' => 'your-connection-name',
],
],
Laravel 4 CacheManagerdoes not support selecting redis connection.
Laravel 4CacheManager不支持选择 redis 连接。
What you need to do is to modify/extend CacheManagerand override createRedisDriver()method.
您需要做的是修改/扩展CacheManager和覆盖createRedisDriver()方法。
Modify this line
修改这一行
return $this->repository(new RedisStore($redis, $this->getPrefix()));
To
到
return $this->repository(
new RedisStore($redis, $this->getPrefix(),
$this->app['config']['cache.redis'])
);
Now you can define your configuration in cache.php
现在您可以在 cache.php 中定义您的配置
'redis' => 'your-connection-name'
