The question is, i am having a problem with session using Docker with Nginx + Yii2 + Redis.
I want use same login on banckend and frontend in Yii2 advanced template.
I just configured all its ok, its work when i do not use Redis, but when i use Redis, dont work.
My configuration is:
- Yii2 advanced 2.0.43
- Nginx 1.17.8
- Redis 4-alpine
My files: docker-compose.yml
version: "3.2"
services:
nginx:
container_name: nginx
image: nginx:1.17.8
ports:
- 805:80 #Yes, i use on port 805, its better for me ;-)
volumes:
- ./vhosts/nginx.conf:/etc/nginx/conf.d/site.conf
- ./:/app
links:
- php
- db
- redis
php:
build: .
container_name: php
volumes:
- ./:/app
environment:
- SESSION_HANDLER=redis
- SESSION_PATH=tcp://redis:${REDIS_PORT}?auth=${REDIS_PASSWORD}
- SESSION_MAX_TIME_LIFE=86400
db:
image: mysql:8
ports:
- '33065:3306' #Its my way, i use on port 33065, depending on each project
volumes:
- /var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=654321
- MYSQL_DATABASE=my-project-5
redis:
image: redis:4-alpine
container_name: redis
command: redis-server --requirepass ${REDIS_PASSWORD}
ports:
- ${REDIS_PORT}:${REDIS_PORT}

PS: To work, i have to disable this and disable Redis too

],
],
'session' => [
// this is the name of the session cookie used for login on the backend
'name' => 'advanced-backend-frontend',
'savePath' => sys_get_temp_dir(),

'baseUrl' => '/painel',
],
...
The projects works on URL:
- http://proj5.local:805/ (frontend)
- http://proj5.local:805/painel/ (backend)
When i say this works like a charm, but only when i don’t use Redis.
If i use Redis, the session do not persists on banckend and frontend
Can someone help me please…

Answer
First, I don’t think you need the frontend/web/php.ini when using Redis cause you will handle everything from Yii, not from php configuration, so I’m just saying that it is useless.
Second, since you’re sharing a lot of components between the two applications, you might want to put the common configuration into some common php files and include them in both applications. Example:
Add this to both frontend and backend configs:
<?php 'session' => require(__DIR__ . '/../../common/config/session.php'),
And create common/config/session.php with contents as:
<?php
return [
'class' => 'yiiredisSession',
'name' => 'my-app-name',
// ...
];
So this way you only define the component once, and same exact configuration is loaded in both places.
Then check one by one the user, session, and request components configuration, and also open the framework’s files either in IDE or the docs and check if there are any missing parameters you might have to tweak.
Also from this post there’s a tip to check Redis and see if and what data gets generated into the database:
https://www.cloudways.com/blog/yii2-redis-configuration/
It might help you debug the problem.
Going further, reading the comments on this class:
https://github.com/yiisoft/yii2-redis/blob/master/src/Session.php
<?php
// ...
/**
* @var string a string prefixed to every cache key so that it is unique. If not set,
* it will use a prefix generated from [[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 $keyPrefix;
You can see there’s this keyPrefix configuration for the Redis Session class, that if left empty, defaults to your application’s ID. And as far as I can remember, with advanced template each app has its own ID:
<?php
return [
'id' => 'app-frontend',
// ...
So this little thing could be making Redis save the sessions with separate prefix for each application. In order to unify it, you must set that keyPrefix.
I would also suggest to start from scratch and setup a new advanced application and implement everything until you make it work. After that, come back to your app and check the differences.
