512MB VPS is widely used for lightweight website, but OOM kill often happens for Tengine if not tuned.
Installation
You can install prebuilt package or compile minimal Tengine without unused modules.
Memory optimization config
Add into tengine.conf
worker_processes 1;
events {
worker_connections 512;
}
- Single worker process saves RAM
- Reduce worker connections limit memory footprint
Disable unused modules
If compile from source, disable modules you never use, for example image filter.

sudo fallocate -l 512M /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Monitor memory
free -h
