daemon

问题 I have a class MyClass which creates 7 threads when it is initialized. One thread is a TCPServer, and the other six are objects of MyClass which the TCPServer uses to process requests. My intention is to create method which can run in the background of MyClass and maintain the 6 threads. The 6 threads correspond to 2 distributed objects obj1 and obj2 replicated with an implementation of Raft called PySyncObj. There are three threads per object. Each cluster of objects obj_1_cluster and obj_2

问题 Would like to get some help with systemd daemon service in Ubuntu. I have a python script I wrote to disable the touchscreen on a Dell XPS which is more of a problem than a useful feature. The script works but I don't want to have to launch it all the time which is why the idea came to my head to write a service file and have systemd launch it for me on startup. The issue I run into is "(code=exited, status=1/FAILURE)". This is my first time and I did a little bit of research before I tried

问题 I have created a python script to regularly scrape a website and store the results in a .json file while at work. This script is set to run without the command line on an infinite loop, so I can have it start in the morning and then just run unimpeded throughout the day. My issue is that at night I'm going to want to kill it so that I can go home, but I don't want to cause any issues with killing it mid-connection or mid-write. I was wondering what was the correct way to handle creating, and

问题 I have a .net core 2.0 program running on Linux (Ubuntu Server 16.04 LTS). I'm trying to shutdown the computer by invoking a process with the following command: sudo shutdown -h now , though when the program is running in the background as daemon service, the shutdown process does not work.

问题 http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch13lev1sec4.html (excerpt from Richard Steven's UNIX Network Programming Vol. 1) includes Signal(SIGHUP, SIG_IGN); as part of the daemon_init function because: ..."We must ignore SIGHUP because when the session leader terminates (the first child), all processes in the session (our second child) receive the SIGHUP signal." The core of the function is: int i; pid_t pid; if ( (pid = Fork()) < 0) return (-1); else
