run goji web app as background process about goji HOT 4 CLOSED

First: unless you have an absolutely pressing need to restart your
application without any downtime, I'd leave Einhorn for now. Goji already
gracefully stops, and you can use nginx/haproxy up front to serve a pretty
503/maintenance page during the short downtime.

Second: supervisor, systemd and Upstart can all do this and should have no
problems. I use supervisord and have zero problems restarting a Go binary.

If you are having problems, post your supervisor.conf config here (or on
Stack Overflow) and I'll gladly help.

im surprised with the lack of detailed coverage on how to run golang web
app in the background process i.e. when i close my ssh window it doesnt go
down together with it.
and a good tool to just do a simple start, stop, AND RESTART!

how do we do it with goji? running it as a background process using
supservisord seems fine with centos but the during restart, the program
will just hang.
and using einhorn. i can start it. but cant restart it...
the einhorn only claimed "You can also seamlessly restart your workers
without dropping any requests" but never document the HOW part.

im seriously frustrated with the current condition. golang is so beautiful
n powerful n yet the deployment is a bitch.

hey thx for the quick reply.

this is my basic supervisord.conf
[supervisord]
http_port=/var/tmp/supervisor.sock ;
logfile=/var/log/supervisor/supervisord.log ;
logfile_maxbytes=50MB ;
logfile_backups=10 ;
loglevel=info ;
pidfile=/var/run/supervisord.pid ;
nodaemon=false ;
minfds=1024 ;
minprocs=200 ;

[supervisorctl]
serverurl=unix:///var/tmp/supervisor.sock ;

[program:goprogram]
command=/home/goprogram/main;
autostart=true;
autorestart=true;
startretries=3;
user=git;

i tried to use monit to just do start and stop (not restart -somehow cant chain stop n start).
it kinda work. bt i do would love to get the restart working. so that i can use it in my post-receive hook in my git push

from goji.

That config looks good to me. Does the supervisor log show any errors? Are
you using the package manager supplied supervisord (older) or via
easy_install/pip (recent)?

I assume a supervisorctl stop goprogram && supervisorctl start goprogram works fine, but that restart does not?

yeap the restart doesnt work. it will just hang and not complete the operation.
yes i was using the old supervisord.

i somehow figured out that i can restart the application using monit. with 'monit restart goprogram' haha
manage to pull off an automatic git-push -> git checkout -> build go -> restart goprogram using monit in my post-receive script.
anyone having the same problem can just ping me, i will share my configs.

@elithrar thank u so much for helping me out. it is reallly kind of u
i will close this issue for now.

cheers
