Singleton mode, the instance is initialized only when the instance is called for the first time. The addintree of the entire system is initialized in this step. We will introduce in detail how to initialize addintree later. Let's take a look at service initialization first. In the initializeservicessubsystem method of servicemanager, you can use addintree to retrieve all configurations under the service plug-in path, read and create specific objects, and add them to the service list. Call the i
process the first part of the obtained files, then the next batch, and continue like this.In some systems, using the-e x e c option will initiate a corresponding process for processing each matching file, rather than executing all the matching files as parameters once; in this way, in some cases, there may be too many processes and the system performance may decline, resulting in low efficiency;The command x a rg s has only one process. In addition, when using the x a rg s command, whether to o

Recently in the study of KVM, the process is not too fast, recently organized a KVM virtual machine technology Learning notes, now share to everyone, but also for everyone to make a reference. A friend in need can come to know.
The management of the KVM virtual machine is mainly through the Virsh command to the virtual machine.
1. View the KVM virtual machine configuration file and running status

to the HTTP restart graceful instructions.
Finally, combining 4 and 52 methods, you can implement a daemon that automatically restarts if a configuration file changes, and restarts if the user's KILL-1 PID signal is received.
The code is as follows:
DECLARE (ticks = 1);
This case would check the config file regularly, if the config file changed, it'll restart it self
If you are want to restart the daemon gracefully, give it a HUP signal

Finally, a Daemon can be implemented by combining the 4 and 5 methods. if the configuration file changes, it will automatically restart. if the user's kill-1 pid signal is received, it also restarts.
The code is as follows:
Copy to ClipboardReference: [www.bkjia.com]
Declare (ticks = 1 );
// This case will check the config file regularly, if the config file changed, it will restart it self
// If you want to restart the daemon gracefully, give it a HUP signal
// B
instruction, similar to the HTTP restart graceful directive.
Finally, the combination of 4 and 52 methods, you can implement such a daemon, if the configuration file changes, he will automatically restart, if the user received the KILL-1 PID signal, will be restarted.
The code is as follows:
At 2011-12-04$init_md5 = md5_file (' config.php ');//Register Signal handlerpcntl_signal (SIGALRM, "Signal_handler", True );p cntl_signal (SIGHUP, ' Signal_handler ', TRUE); $job _flag = FALSE;
The most bt is here, and there is no application. Run () -- and all are read from addins.
