There are several ways to update a FIO node, however, all of them basically come down to just replacing the nodeos binary; the differences being how the nodeos binary is running, i.e. as a daemon (using systemctl). While the instructions below pertain specifically to a FIO node being installed and configured using a pre-built FIO deb package, it will apply to production-level nodes.
For a FIO node installed using a pre-built FIO package, including the full package as well as the tar and minimal packages, the process of updating the nodeos binary is a matter of
- Downloading the latest package
- Extract the FIO blockchain binaries
- Replace the installed binaries with the new ones
The following script assumes that the node was installed using the full FIO package deb based on instructions found at Installation Using Packages, specifically that the nodeos application is running as a daemon and that logging is configured.

echo "Before proceeding it is recommended to download the most recent snapshot and/or blocks.log"
echo "as a safetly precaution as a node shutdown and start up may corrupt the database."
echo "Caution: Do not perform a 'systemctl restart fio-nodeos' as the restart action occurs too"
echo "fast to properly shutdown, capture the current state, and start up a FIO node!"
echo "Download lastest snapshot and/or blocks.log from https://snap.blockpane.com"
echo "Shutting down fio-nodeos..."
#sudo systemctl status fio-nodeos
if (systemctl -q is-active fio-nodeos); then
sudo systemctl stop fio-nodeos >/dev/null 2>&1
echo "Confirm that nodeos is stopped before proceeding"
# A log rotation is needed; not doing this causes odd logging behavior; while nodeos will
# start up fine either
# - nodeos loses its pointer to the end of the log file
# - nodeos has to re-read the entire log file which may take a long time
echo "Forcing a log rotation..."
sudo logrotate -vf /etc/logrotate.d/fio-nodeos >/dev/null 2>&1
sudo rm -f clio fio-nodeos fio-nodeos-run fio-wallet
