twistd – run Twisted applications (TACs, TAPs)
Read a twisted.application.service.Application out of a file and run
-n, –nodaemon Don’t daemonize (stay in foreground).
No-op for backwards compatibility.
Save the Stats object rather than the text output of the pro‐
Run the application in the Python Debugger (implies –nodaemon
option). Sending a SIGINT or SIGUSR2 signal to the process will
drop it into the debugger.
The specified tap/aos file is encrypted.
–euid Set only effective user-id rather than real user-id. This option
has no effect unless the server is running as root, in which
case it means not to shed all privileges after binding ports,
retaining the option to regain privileges in cases such as
spawning processes. Use with caution.
Do not save shutdown state.
Behave as though the specified Application has no process name
set, and run with the standard process name (the Python binary
in most cases).
Log to a specified file, – for stdout (default: twistd.log).
The log file will be rotated on SIGUSR1.
A fully-qualified name to a log observer factory to use for the
initial log observer. Takes precedence over –logfile and –sys‐
Chroot to a supplied directory before running (default: don’t
chroot). Chrooting is done before changing the current direc‐
Change to a supplied directory before running (default: .).
The uid to run as (default: don’t change).
The gid to run as (default: don’t change).
The (octal) file creation mask to apply. (default: 0077 for dae‐
mons, no change otherwise).
Choose which reactor to use. See –help-reactors for a list of
List the names of possibly available reactors.
–spew Write an extremely verbose log of everything that happens. Use‐
ful for debugging freezes or locks in complex code.
Read the given .tap file (default: twistd.tap).
Load an Application from the given .tas (AOT Python source)
option overrides -f. This option implies –no_save.
Log to syslog instead of a file.
Print version information and exit.
Note that if twistd is run as root, the working directory is not
searched for Python modules.
A running twistd accepts SIGINT for a clean shutdown and SIGUSR1 to
rotate log files.
