nix daemon - daemon to perform store operations on behalf of non-root clients

nix daemon [option…]

•
Run the daemon:
# nix daemon
•
Run the daemon and listen on standard I/O instead of binding to a UNIX socket:
# nix daemon --stdio
•
Run the daemon and force all connections to be trusted:
# nix daemon --force-trusted
•
Run the daemon and force all connections to be untrusted:
# nix daemon --force-untrusted
•
Run the daemon, listen on standard I/O, and force all connections to use Nix’s default trust:
# nix daemon --stdio --default-trust

This command runs the Nix daemon, which is a required component in multi-user Nix installations. It runs build tasks and other operations on the Nix store on behalf of non-root users. Usually you don’t run the daemon directly; instead it’s managed by a service management framework such as systemd on Linux, or launchctl on Darwin.

Note that this daemon does not fork into the background.

•
--default-trust
Use Nix’s default trust.
•
--force-trusted
Force the daemon to trust connecting clients.
•
--force-untrusted
Force the daemon to not trust connecting clients. The connection will be processed by the receiving daemon before forwarding commands.
•
--process-ops
Forces the daemon to process received commands itself rather than forwarding the commands straight to the remote store.
      This is useful for the `mounted-ssh://` store where some actions need to be performed on the remote end but as connected user, and not as the user of the underlying daemon on the remote end.
•
--stdio
Attach to standard I/O, instead of trying to bind to a UNIX socket.
•
--debug
Set the logging verbosity level to ‘debug’.
•
--log-format format
Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
•
--print-build-logs / -L
Print full build logs on standard error.
•
--quiet
Decrease the logging verbosity level.
•
--verbose / -v
Increase the logging verbosity level.

•
--help
Show usage information.
•
--offline
Disable substituters and consider all previously downloaded files up-to-date.
•
--option name value
Set the Nix configuration setting name to value (overriding nix.conf).
•
--refresh
Consider all previously downloaded files out-of-date.
•
--version
Show version information.

Note

See man nix.conf for overriding configuration settings with command line flags.
