Example of PHP + swoole + Linux for system monitoring and performance optimization


The example of this paper describes the implementation of PHP + swoole + Linux system monitoring and performance optimization operation. To share with you for your reference, as follows:

Server monitoring

Port monitoring PHP running shell script

class Server {
  const PORT = 8811;
   *Get the port information specified by the port. If it is running, return 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($result != 1) {
      //Send alarm service email and SMS
      /// todo
      echo date("Ymd H:i:s")."error".PHP_EOL;
    } else {
      echo date("Ymd H:i:s")."succss".PHP_EOL;
 *Swoole millisecond timer; run script every 2 seconds
swoole_timer_tick(2000, function($timer_id) {
  (new Server())->port();
  echo "time-start".PHP_EOL;

Linux executes commands on 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-**

Use. Sh (shell script) to restart the service smoothly according to the 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 &
