First, the Linux daemonLinux servers start with a number of system services that provide local and network users with a system-functional interface for Linux that is directly targeted to applications and users. The programs that provide these services are executed by daemons running in the background.A daemon is a process that has a long lifetime. They are indepe

Linux programming-special process daemon and linux programming daemonWhat is a daemon?
Daemon Process (Daemon Process) is a background service Process in Linux. It is a long-lived proce
For Java, typically one application has only one process--JVM. Unless a new process is derived or opened in the code.threads, of course, are opened by the process. When the process that opened the thread leaves, the thread is no longer there.So, for Java, threads are completely free to be generated by their own APIs. For example, New Thread (). But the process is different and must be done by invoking the OS API, such as Runtime.getRuntime.exec (). So, the process is the OS level concept.The dif
Python implements the compiling of the daemon in Linux, and the python daemon
The example in this article describes how to compile the daemon process of Python in Linux. It is for your reference and I believe it will be helpful for your Python program design. The specific me
Daemon is a special process running in the background. It is independent of the control terminal and periodically executes a task or waits to process some events. Daemon is a useful process. Most Linux servers are implemented using daemon. For example, the Internet server inetd and the Web Server httpd. At the same tim
The Linux daemon (Daemon) is a Linux background service process that is disconnected from the control terminal and is managed directly by the Linux init process, and even if you close the console, Daemon works in the background.In
Many services are turned on when the Linux/unix system is booted, and these services are called daemons (also called daemon processes). A daemon is a process that is detached from the control terminal and periodically performs some sort of task in the background or waits for certain events to be processed, leaving the terminal in order to prevent the process from
