Extra things to be set in the command line before setting up PowerPanel.

One issue with PowerPanel is that it constantly writes to /usr/local/PPB/db_local/filedb.log (https://www.reddit.com/r/HomeServer/comments/usno37/cyberpower_powerpanel_business_linux_excessive/). We fix this by installing and using Anything-sync-daemon to put the directory into a ram disk that gets synced to disk occasionally.

• Connect to admin@cyberpower-ppb using SSH and login with admin as the password.

# Change the default password:
passwd
 
# Change the time zone to the one the server is in:
# Find your time zone using:
timedatectl list-timezones
# Then set it with:
sudo timedatectl set-timezone Australia/Perth
 
# Set the hostname:
sudo hostnamectl set-hostname Cyberpower-PPB
 
# Make sure the system is up to date
sudo apt update && sudo apt upgrade
 
# Install Anything-sync-daemon
sudo apt install make pv zstd
git clone https://github.com/graysky2/anything-sync-daemon.git /tmp/asd
cd /tmp/asd
sudo make install-systemd-all
cd /
rm -R /tmp/asd
sudo nano /etc/asd.conf
# Edit the following lines:
WHATTOSYNC=()
#VOLATILE="/tmp"
#USE_OVERLAYFS="no"
# into:
WHATTOSYNC=('/usr/local/PPB/db_local')
VOLATILE="/dev/shm"
USE_OVERLAYFS="yes"
# Write out the file and exit
# Check to see if configured properly
sudo asd p
# Enable to run at startup
sudo systemctl enable asd.service
 
sudo reboot 0
