For the last few years I had been using DigitalOcean to host this website & a few others, file sync and my git repos. Fairly low traffic stuff on a single VPS instance. It was nice and cheap. But still… the recent 20% price increase got me thinking…
Can I build my own server?
Turns out I could! And it was a lot of fun.
I used a 10th generation Intel NUC with a 6-core i7 CPU, 32GB RAM and a 1TB NVMe SSD. Yes, overkill. But the key parameter is power usage. The whole system draws ~7W at idle. What a wonderful little machine!
For the OS I decided to install Ubuntu (22.04 LTS). I’m familiar with it and it was useful having the same OS on both systems. Then, some housekeeping on the old server:
- removed old disconnected websites
- put websites under separate user accounts
- moved from Gogs to Gitea
- organized my git repositories
- setup a more thorough backup procedure
When I had everything set up to begin the migration, I brought the NUC to the new Prague data center and turned it on. Then I started moving websites and services one by one. Soon the old VPS instance will be empty and I’ll be able to shut it down.
|DigitalOcean||1x vCPU||2GB||50GB + $extra|
|Intel NUC||6x CPU / 12 threads||32GB||1000GB|
There’s plenty of headroom for no extra money and I feel like I’m more self-reliant.
To elaborate a little bit on the backup procedure:
- daily rsync (soon → rsnapshot)
- daily mysql dumps
- /etc and apt package list versioned in git
- secondary NUC ready for deployment
- backup VPS account ready for deployment (prepaid credit)
- up-to-date checklist for configuring the whole software stack
