问题
In our application, we use a Passport middleware (localStrategy, sessions are stored in a MongoStore). We decided to use Clusters in order to speed up and ease on a server. The problem is that after this change, passport always is in "not authorized" state. Is it possible to use passport (localStrategy) with clustering?
回答1:
Passport store session data in memory. With Clustering, It is possible for passport to store data in a cluster and other requests handle by other clusters. You must use a session store. I recommend using connect-redis
