Linux daemon can be divided into two categories: Independent startup daemon and super daemon Based on the startup and management methods of daemon: stand_alone ): this type of process is resident in memory after it is started, so it will continue to occupy system resources.

In the recent days of writing Linux C service programs, daemon and thread creation have failed.After the discovery program is daemon, the thread is all hung up.After checking some documents, I finally got to know why.The operation of the daemon function is actually very easy,1.fork a process, 2.

These tasks that accept user input/COMPUTE/storage/output in Linux systems are provided by Linux system services to help us, and some of these system services need to beWaiting for the user's input or at any time to respond to user requests and so on.The daemon thread (Deamon) usually serves the user in the background of the system as it is activated when the sys

leader process.C, call Setsid to create a new session. Setsid can cause:1) The calling process becomes the first process of a new session.2) The calling process becomes the leader process of a process group.3) The calling process does not control the terminal. (Fork once again to ensure that the daemon process does not open the TTY device afterwards)D. Change the current working directory to the root directory.E, close the file descriptor that is not

the process will not be interrupted by terminal information generated by any terminal2. Why to introduce daemons:Because in Linux, each system communicates with the user interface called the terminal, every process that starts from this terminal will be attached to this terminal, this terminal is called the control terminal of these processes, when the control terminal is closed, the corresponding process will automatically shut down. But the

Anything-sync-daemon (ASD) is a was a diminutive pseudo-daemon designed to manage target directories in TMPFS and to period ically sync them back to your physical disc (HDD/SSD). This was accomplished via a symlinking step and an innovative use of rsync to maintain back-up and synchronization between The other. One of the major design goals of ASD is a completely transparent user experience.Https://wiki.arc

Rsyslog ProcessSyslog is a tool that records logging in the system and can support local or remote log writes.In the LinuxMint environment, the upstart-based daemon is placed in the/etc/init/directory, and the following command can be used to view the specific startup script:[Email protected]:/var/log$ less/etc/init/rsyslog.confTo see if the current RSYSLOGD has been started:[Email protected]:/var/log$ initctl List | grep rsyslogRsyslog start/running,
