You can also access your own 192.168.33.55:3000 inside the virtual machine

So I started to modify nginx to forward 8080 to port 3000 of the virtual machine

I guess that when you use curl to access: 3000, you use the root account, and when you use nginx to access: 3000, you may not use the root account. Judging from the log, when the tcp connection is permission denied, some online information says it is a problem with the SELinux configuration. You can check again according to this idea
Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AMLoad balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AMAlternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
