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Consider all previously downloaded files out-of-date.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