Nohup SBCL ubuntu cannot read from standard input

On Ubuntu, I compiled sbcl 1.0.35 with threads. I can happily use sbcl from the command line, and my hunchentoot site works with threads, but when I log out, it disappears. When I try nohup sbcl

nohup./src/runtime/sbcl --core output / sbcl.core

I get

(SB-IMPL :: SIMPLE-STREAM-PERROR "cannot be read from ~ S" # 9)

I tried various combinations of redirecting standard input to / dev / null or a file and using the script command line option, but I did not quite understand what was going on.

How can I run sbcl from the command line on linux with nohup and save my replica (website)?

Dmity-vk sent me on the right path, thanks. SBCL tries to start the replica when it starts and reads from standard input. When you use nohup , the in standard is redirected and cannot be read. Then the SBCL goes to the debugger, which tries to read from the standard into ... hence an infinite loop. The --script tag --script close to a solution, except that it has (quit) after reading the script. So I put an infinite loop in the script and voila.

so on an ubuntu server with sbcl this should allow you to start the hunchentoot server

 sudo nohup ./run-sbcl.sh --script foo.lisp > /dev/null 2> /dev/null &

where foo.lisp has as its last lines something like

 (defvar *alive* t) (loop (sleep 1000) (if (not *alive*) (quit)))

Andrei Moskvitin’s RESTAS Web Site (“REST Application Server”) contains code to properly demonstrate the SBCL instance. See http://github.com/archimag/restas/blob/master/contrib/restas-daemon.lisp . You can easily break parts related to RESTAS.

You can run SBCL in the Gnu Screen and then disconnect from the session.

It also gives you the option to reconnect to your REPL.
