说明
unbound-checkconf validates the Unbound DNS resolver configuration file for syntax errors and configuration problems. It checks the specified file or the default configuration location if no file is given. The tool verifies configuration syntax, checks for valid option values, and ensures referenced files (like key files and certificates) exist and are readable. Running this before restarting Unbound prevents service disruption from configuration errors. The -o option extracts specific configuration values, useful for scripting or verifying settings. For disabled options, an empty line is printed.
