Php-fpm dead solution, script background restarts automatically

Php-fpm dead solution, script background restarts automatically

I used nginx + php7 to build a server, because the request volume is too large, and there are pending tasks in php, causing the php-fpm to often die during peak hours, the maximum number of php-fpm processes has been changed to 1000, which is still too high. The cpu is also overloaded. It is annoying to manually restart each time. Therefore, I wrote a shell script, the backend listens to the php-fpm and allows it to restart after it reaches a certain number. This effectively solves the manual restart and crash issues.

1. Declare the document header and define variables

#! /Usr/bin/env bash

MaxCount = 300 # maximum number of php-fpm Processes

BasePath = $ (cd 'dirname $ 0'; pwd) # directory of the script

PidFilePath = "$ basePath/pid. conf" # saving files with pid

ErrorFilePath = "$ basePath/error.txt" # file storage for error logs

2. Define key functions

GetDateTime (){

Date "+ % Y-% m-% d % H: % M: % S"

}

Restart (){

The kill-USR2 $ (cat/usr/local/php/var/run/php-fpm.pid)

}

Start (){

/Usr/local/php/sbin/php-fpm

}

Stop (){

Kill $ (cat/usr/local/php/var/run/php-fpm.pid)

}

Stopweb (){

If [-f "$ pidFilePath"]; then

Kill $ (cat "$ pidFilePath") 2>/dev/null

Rm-r "$ pidFilePath"

Fi

}

Main (){

Stopweb

Echo "$"> "$ pidFilePath"

While (1 ))

Do

Count = $ (ps aux | grep-c php-fpm)

If ("$ count"> = "$ maxCount"); then

Restart

Date = $ (getDateTime)

Echo "date: $ date, maxCount: $ maxCount, count: $ count"> "$ errorFilePath"

Fi

Sleep 10

Done

}

3. Add startup parameters

Case $1 in

"Restart") restart

;;

"Start") start

;;

"Stop") stop

;;

"Run") main

;;

"Stopweb") stopweb

;;

*) Echo "cmd error! "

;;

Esac

4. Terminate the script

Exit 0

Run commands

./Webserver restart # restart php-fpm

./Webserver start # enable php-fpm

./Webserver stop # stop php-fpm

Setsid./webserver run & # enable listening and run in the Background &

./Webserver stopweb # Stop listening
