问题 I setted up celeryd and celerybeat as daemons, and they worked until not too long. But since some time, it wont start workers and not create pid files. Here is my /etc/default/celeryd : # Name of nodes to start CELERYD_NODES="w1 w2 w3 w4 w5 w6 w7 w8" # Extra arguments to celeryd CELERYD_OPTS="--time-limit=300 --concurrency=8" # Where to chdir at start. CELERYD_CHDIR="/srv/www/web-system/myproject" # %n will be replaced with the nodename. #CELERYD_LOG_FILE="/var/log/celery/%n.log" #CELERYD_PID

问题 I have a daemon script written in ruby which responds to commands like daemon start and daemon stop . It's executable with shebang #!/usr/bin/env ruby and it works invoked from terminal. I need to start the daemon on login and stop it on logout. Background info: KDE, zsh. I already tried to make two separate shell scripts with daemon start and daemon stop and place them in ~/.kde4/Autostart | ~/.kde4/shutdown . The scripts start.sh and stop.sh are working in terminal, but no luck in autostart

Can I have some code constantly run inside Django like a daemon

问题 I'm using mod_wsgi to serve a django site through Apache. I also have some Python code that runs as a background process (dameon?). It keeps polling a server and inserts data into one of the Django models. This works fine but can I have this code be a part of my Django application and yet able to constantly run in the background? It doesn't need to be a process per se but a art of the Django site that is active constantly. If so, could you point me to an example or some documentation that

Correct daemon behaviour (from PEP 3143) explained

由 陌路散爱 提交于 2019-12-18 05:47:21
问题 I have some tasks [for my RPi] in Python that involve a lot of sleep ing: do something that takes a second or two or three, then go wait for several minutes or hours. I want to pass control back to the OS (Linux) in that sleep time. For this, I should daemonise those tasks. One way is by using Python's Standard daemon process library. But daemons aren't so easy to understand. As per the Rationale paragraph of PEP 3143, a well behaved daemon should do the following. Close all open file

I have to add my logs to different directory such as

how to set a class as daemon with tomcat?

由 人盡茶涼 提交于 2019-12-11 11:50:06
问题 I'm new on the java universe, also new in the tomcat world. So, the issue is: I need to run a java class as a daemon. This class should be able to comunicate with the tomcat requests. In the past: when I did this in C, I executed the binary file as a background process. Could you give me some suggestions how to proceed? thanks ind advance!. 回答1: So it sounds like there are two parts to the answer. The first one is to make sure that your daemon gets started up with the tomcat container, and

iOS daemons. are they legal for AppStore?

问题 Can't find out if daemon application can be run on non-jailbroken iPhone. And what is Apple policy about this stuff? I don't really know if my idea is possible at all... I wonder if it's possible to create such a daemon that can intercept outcoming user call and play custom tone signal while remote user does not answer our call. Almost all cell-operators provides a service of custom call tones which means you can listen to some music while waiting for response... This drives me wild. 回答1:
