Yacy for Raspberry PI – notes

TLDR: Setup an Yacy Raspbian Image for your PI, presetup with minimal configuration needed. Yacy is an distributed search engine.

Maybe my memory notes are of use to someone else too.

Allow from outside to port 80, 8091,8092

Allow every port from internal subnet

  • The ports used in Yacy are 8091 for http, 8092 for https.
  • Enable SSH-server and any pub-keys and authorized hosts for easy login.
  • Turn off/on any features like ssh with raspi-config.
  • Change the default PI-user password.
  • Change the password for default Yacy-admin.
  • JVM for Yacy is set as max 856 mb mem – this should surely be more if your pie has it.
  • Takes a while to start, be patient.
  • Logs for yacy are under ~/yacy/DATA/LOG
  • Backup and compress the SD-image.https://raspberrypi.stackexchange.com/questions/311/how-do-i-backup-my-raspberry-pi#313










Adapters in Japan

Japan uses 110v and has a different adapter hole standard than in Europe.

Most people do buy an good travel adapter before going away, but what if you forgot, or if your current adapter breaks during the stay?. Fear not, adapters for European to Japan are available at least at the bigger electronical chains. I bought my adapters at Yodobashi in Kyoto (just walk a hundred meter north when leaving the main entrance, it’s on the left side where you see an mcshit– sorry, mcdonalds on the right).

I bought two slightly different models, (one with slightly tighter plug holes that were perfect for my mac adapter).







WIFI in Japan – Prepaid travel card

After staying in Kyoto for two months, it’s clear that the public Kyoto WiFi, and the one offered in public cafes and so on is not enough for a foreigner, as we’re always on the go. Pocket WiFi seems really popular and expensive, but if you have an extra phone, you might as well just pick up a surf SIM-card with 2GB data preloaded and valid for three months. If staying longer in Japan it’s much cheaper than a pocket WiFi, depending on your use case of course.

I bough mine at Bic Camera (When leaving Kyoto station main entrance, just turn left directly, walk a hundred meters and you’ll see the building), but I would be surprised if Yodobashi didn’t have them.


They look like this. The setup is supersimple, and instructions in English are included.
