Yes! I use Ubuntu 22.04. Alpine would help with base memory but MariaDB still want 128MB for buffer pool alone.

Alpine with musl libc also has subtle compatibility issues with some PHP extensions. The 50MB savings is not worth the debugging time for most people.

It's always DNS. Always.

BainanReal here. I use Alpine for containers, not VMs. Different calculus there.

Thank you all for the knowledge. Final update: I upgrade to 512MB Contabo plan, same stack works perfect. The 128MB VPS is now my WireGuard server. Happy ending.

Perfect. That's exactly what 128MB is good for. Thread resolved sensibly, which is rare on the internet.

Happy ending and I learned some new words. Good thread.

Guru2007 here, also late. Did anyone try reducing MariaDB's innodb_buffer_pool_size to 32MB? It will perform terribly but might not OOM.

I try 64MB and it start but WordPress admin is unusable. 32MB maybe for CLI only. But yes, technically it boots.

InnoDB with 32MB buffer pool is basically doing direct disk IO for everything. You could use MyISAM with key_buffer=8MB and get similar or better performance, but then you lose transactions and crash safety.

The journey continue. Maybe I try MyISAM for historical curiosity. But not on production. Thank you all!
