System Signal Processing in go

package mainimport "fmt"import "os"import "os/signal"import "syscall"func main() {go SignalProc()done := make(chan bool, 1)for {select {case <-done:break}}fmt.Println("exit")}func SignalProc() {sigs := make(chan os.Signal)signal.Notify(sigs, syscall.SIGINT, syscall.SIGUSR1, syscall.SIGUSR2, syscall.SIGHUP, os.Interrupt)for {msg := <-sigsfmt.Println("Recevied signal:", msg)switch msg {default:fmt.Println("get sig=%v\n", msg)case syscall.SIGHUP:fmt.Println("get sighup\n")case syscall.SIGUSR1:fmt.Println("SIGUSR1 test")case syscall.SIGUSR2:fmt.Println("SIGUSR2 test")}}}

// Kill-usr1 10323 kill-usr2 10323 kill-N 2 10323 you can configure SIGUSR1 to reload sigusr2 and reload game base.

 

Capture Ctrl + C signals

 signal.Notify(c, os.Interrupt)

Command: Kill-num processid (PID)

 

Letter Comment comment	Numeric Value	Meaning
Hup	1	Slave in the control or in the program
Int	2	INSERT command of zookeeper (same as Ctrl + C)
Quit	3	The Forward Command in zookeeper (same as Ctrl + \)
Term	15	Program stopping command
Kill	9	Program logging and stopping commands (brute force splitting)
Cont	18	Program re-activation command (stop (19) and then re-launch)
Stop	19	Program stop command (same as Ctrl + Z)

Generally, if the system is shut down, the system will first send the limit of the term (15) to stop the process. If not, the system will send kill (9) to stop the program.
