本文实例讲述了PHP swoole linux实现系统监控和性能优化操作。分享给大家供大家参考,具体如下:
服务器监控
端口监控php运行shell脚本
代码语言:javascript复制class Server {
const PORT = 8811;
/**
* 获取端口指定端口信息;如果在运行返回1;否则返回0;
*/
public function port() {
$shell = "netstat -anp 2 /dev/null | grep ". self::PORT . " | grep LISTEN | wc -l";
$result = shell_exec($shell);
if($result != 1) {
// 发送报警服务 邮件 短信
/// todo
echo date("Ymd H:i:s")."error".PHP_EOL;
} else {
echo date("Ymd H:i:s")."succss".PHP_EOL;
}
}
}
/**
* swoole毫秒定时器;每隔2秒运行一下脚本
*/
swoole_timer_tick(2000, function($timer_id) {
(new Server())- port();
echo "time-start".PHP_EOL;
});
linux在终端执行命令并且写入到文件里面
nohup /usr/local/php/bin/php/www/swoole/thinkphp_swoole/script/monitor/server.php /www/swoole/thinkphp_swoole/script/monitor/a.txt-**
根据端口别名使用.sh(shell脚本)平滑重启服务
代码语言:javascript复制echo "loading..."
pid=`pidof live_master`
echo $pid
kill -USR1 $pid
echo "loading success"
后台启动swoole
nohup /usr/local/php/bin/php /www/swoole/thinkphp_swoole/server/ws.php /www/swoole/server/thinkphp_swoole/swoole.log &
