Path Configuration File


Changing the path settings in this file is usually unnecessary. For non-standard directory paths, use the SAWTOOTH_HOME environment variable instead of this configuration file.

The path.toml configuration changes the Sawtooth data_dir directory. This file should be used only when installing on an operating system distribution where the default paths are not appropriate. For example, some Unix-based operating systems do not use /var/lib, so it would be appropriate to use this file to set data_dir to the natural operating system default path for application data.

An example file is in /etc/sawtooth/path.toml.example. To create a path configuration file, copy the example file to the config directory and name it path.toml. Then edit the file to change the example configuration options as necessary for your system.

This file configures the following settings:

  • key_dir = path

    Directory path to use when loading key files

  • data_dir = path

    Directory path for storing data files such as the block store

  • log_dir = path

    Directory path to use to write log files (by default, an error log and a debug log; see Log Configuration File).

  • policy_dir = path

    Directory path for storing policies

The default directory paths depend on whether the SAWTOOTH_HOME environment variable is set. When SAWTOOTH_HOME is set, the default paths are:

  • key_dir = SAWTOOTH_HOME/keys/

  • data_dir = SAWTOOTH_HOME/data/

  • log_dir = SAWTOOTH_HOME/logs/

  • policy_dir = SAWTOOTH_HOME/policy/

For example, if SAWTOOTH_HOME is set to /tmp/testing, the default path for data_dir is /tmp/testing/data/.

When SAWTOOTH_HOME is not set, the operating system defaults are used. On Linux, the default path settings are:

  • key_dir = /etc/sawtooth/keys

  • data_dir = /var/lib/sawtooth

  • log_dir = /var/log/sawtooth

  • policy_dir = /etc/sawtooth/policy

Sawtooth also uses config_dir to determine the directory path containing the configuration files. Note that this directory is fixed; it cannot be changed in the path.toml configuration file.

  • If SAWTOOTH_HOME is set, conf_dir = SAWTOOTH_HOME/etc/

  • If SAWTOOTH_HOME is not set, conf_dir = /etc/sawtooth
