PHP+swoole+linux Implementation System Monitoring and Performance Optimization Operation Example

This paper describes the implementation of PHP+swoole+linux system monitoring and performance optimization operations. Share it for your reference, as follows:

Server monitoring

Port Monitor php Run shell Script

class Server {
  const PORT = 8811;
  /**
   *  Get port specified port information ; If you return when running 1 ; Otherwise return 0 ; 
   */
  public function port() {
    $shell = "netstat -anp 2>/dev/null | grep ". self::PORT . " | grep LISTEN | wc -l";
    $result = shell_exec($shell);
    if($result != 1) {
      //  Send alarm service   Mail   SMS 
      /// todo
      echo date("Ymd H:i:s")."error".PHP_EOL;
    } else {
      echo date("Ymd H:i:s")."succss".PHP_EOL;
    }
  }
}
/**
 * swoole Millisecond timer; Every interval 2 Second run 1 Lower script 
 */
swoole_timer_tick(2000, function($timer_id) {
  (new Server())->port();
  echo "time-start".PHP_EOL;
});

linux executes commands at the terminal and writes them to a file

nohup /usr/local/php/bin/php/www/swoole/thinkphp_swoole/script/monitor/server.php > /www/swoole/thinkphp_swoole/script/monitor/a.txt-**

Smooth restart of service using. sh (shell script) based on port alias

echo "loading..."
pid=`pidof live_master`
echo $pid
kill -USR1 $pid
echo "loading success"

Start swoole in the background

nohup /usr/local/php/bin/php /www/swoole/thinkphp_swoole/server/ws.php > /www/swoole/server/thinkphp_swoole/swoole.log &
