Name

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

Synopsis

nix daemon [/option/…]

Examples

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

Description

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.

Options

--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.

Logging-related options

--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.

Miscellaneous global options

--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--refresh Consider all previously downloaded files out-of-date.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.
