🦞 After-Action Review: Ollama Install on 47.107.70.224

What went wrong

  1. Blind curl | sh approach — I jumped straight to the standard one-liner without thinking. It got flagged by security, and I kept trying the same pattern instead of pivoting immediately.

  2. Wasted ~20 minutes on slow downloads — I kept re-trying curl directly on the remote server. That box (likely Alibaba Cloud, China) has garbage international bandwidth. I should have noticed the crawl speed immediately and switched strategy.

  3. Multiple zombie processes — First attempt left behind 3+ competing curl | sh processes that fought over the binary file, causing “Text file busy” errors. Didn’t clean up before retrying.

  4. Wrong GitHub URLs — Tried .tgz first, but the actual release artifact was .tar.zst. Should’ve checked the GitHub API earlier instead of guessing.

  5. Forgot HOME env var — The $HOME is not defined crash took an extra cycle to fix. Should’ve known systemd services don’t inherit user env.

  6. Leftover process on port 11434 — Didn’t kill the background ollama serve & before creating the systemd service, causing port conflicts.

What went right

  1. Download-to-local-then-SCP strategy — Once I pivoted to downloading on my server first (fast connection), the whole transfer was clean. This should’ve been step one.

  2. Proper systemd service — Got auto-restart and boot persistence right.

  3. Final result is solid — Ollama is running, listening on 0.0.0.0, service enabled.

What I should have done

  1. Download binary on my server → SCP → extract — the winning approach, just should’ve started there
  2. Check GitHub API for exact filename before guessing URLs
  3. Kill stale processes before each retry
  4. Set up systemd from the start with HOME included
  5. Check for GPU first to set expectations

Time breakdown

Lesson learned: When dealing with Chinese cloud servers, never download from international sources directly. Always proxy through a fast intermediary. 🦞
