#DigitalOcean #Openbsd #Mastodon #Notes

Mastodon_on_OpenBSD.doc

Notes from my mastodon test instance config.
Assumptions: you own some domain-name and its pointing to the ip of this instance. I'm calling it my.domain
This may or may not work for you. I've moved notes around so things might break.
I'm basically just doing config as described here:
https://github.com/tootsuite/documentation/blob/master/Running-Mastodon/Production-guide.md

# Start: I'm creating the machine on DigitalOcean.
# You can probably skip this part ( 9.)
### DigitalOcean guest creation ###
1.#create digitalocean host. 10$ (non-zfs freebsd host) i did this on a 5$ but upgraded later.
#make sure you have a ssh key added.

2. #connect [email protected]

3. #because the internet says so.
$ sudo swapoff /dev/gpt/swap

4. #(needed to write to raw disk apparently, according to ancient scrolls of mine).
$ sudo sysctl kern.geom.debugflags=0x10
kern.geom.debugflags: 0 -> 16

5. #Fetch the newest OpenBSD
$ fetch http://ftp.eu.openbsd.org/pub/OpenBSD/6.1/amd64/miniroot61.fs
miniroot61.fs                                 100% of 4480 kB 5297 kBps 00m01s


6. #Owerwrite disk with miniroot 
$ sudo dd if=miniroot61.fs of=/dev/vtbd0 bs=512k
8+1 records in
8+1 records out
4587520 bytes transferred in 0.027193 secs (168701557 bytes/sec)

7. sudo reboot
