Script Updates
With the recent release of 1.4.0, my witness did NOT just update and move on. I ran into a TON of problems and ultimately had to just start over completely with a fresh deploy.
In my work, my script was updated quite a bit and I've gotten it back into a "one-click" state. You can literally go to Digital Ocean, deploy an Ubuntu 20.10 droplet, and simply paste in the script with their User Data feature.
This does download the mongodb and restore it, which does take awhile. You can log into the server and watch the progress with this command tail -fn5 /var/log/cloud-init-output.log
Once the script is done, just type mongo and then show dbs to confirm the hsc database exists, and is around 15GB.
Then, just two commands:
cd /var/witness
pm2 start app.js --no-treekill --kill-timeout 10000 --no-autorestart --name engwit
You can 'watch' the logs with pm2 logs but the real way to keep track is this:
grep ahead /root/.pm2/logs/engwit-out.log | tail
You're looking for Hive blockchain is 0 blocks ahead and again this can take awhile.
Finally, verify everything is working node find_divergent_block.js
This will generate some output, but hopefully ends with ok
If not, you have issues and may need to start over, but if you see ok then everything is in full working order!
Vote my witness
I appreciate all the support I've received for my witness but I have lost some votes and fallen quite a few positions so I'm actively working to build that up a bit more. You can vote for witnesses very easily.
