Remove a FIO installation and cleanup leftover FIO install artifacts

Uninstall FIO package

The following instructions will remove FIO artifacts installed during a package install. For a listing of those files, see FIO Package Install.

APT Remove

To remove a package installed with dpkg, apt, or apt-get, execute the corresponding command, e.g. dpkg --remove <package>. In the following instructions apt will be used, however, note that whichever command is used, it only partially cleans up an install and additional steps must be taken.

apt remove should remove everything except configuration and data. Configuration would include users, groups, ini and json files, and data would include state, history, etc.

sudo apt remove fioprotocol

apt purge should remove everything including configuration, and data!

sudo apt purge fioprotocol

FIO Installation artifact cleanup

However, currently both remove and purge do not do exactly what is implied. Note: purge appears to remove /var/log/fio/nodeos.log but does not remove any log backups (rotated logs).

Directories/files/configuration that should be removed when using apt remove include:

  • /etc/fio/genesis.json
  • /usr/local/bin/cleos
  • /usr/local/bin/fio-cleos
  • /usr/local/bin/nodeos

In addition to the items above, directories/files/configuration that should be removed when using apt purge include:

  • /var/lib/fio
  • /var/log/fio
  • fio-nodeos service
  • fio-wallet service
  • fio user
  • fio group

🚧
