回复了 cs5117155 创建的主题 › PHP › 使用 workeman/redis 时,如何才能避免回调地狱

@zjsxwc
```php
$charecabinet_id =33;
$getDeferred = new React\Promise\Deferred();
$initialPromise = $getPromise =$deferred= $getDeferred->promise();

$initialPromise->then(function() use($redis,$initialPromise){

$redis->set('key2', 'value32', function ($result)use($initialPromise) {
$initialPromise->resolve($result);
});

return $initialPromise;
})->then(function($result)use($charecabinet_id,$initialPromise){
var_dump($charecabinet_id);
$row_count = self::$db->update('xxx')
->cols(array('heart_time'=>time()))
->where("ID=$charecabinet_id")->query();

return $initialPromise->resolve($row_count);
})->otherwise(function (\Throwable $x) {
// Propagate the rejection
echo 'Reject ' . $x->getMessage(); // 3
});
```
我参考你的写法，发现只运行到设置 key2=value32，第二个`then`没有运行下去了,是哪里姿势不对吗

刚刚我用 ab 测试工具,日志里面只记录时间戳，发现最后一共有 5000 行时间戳,
file_put_contents($filename, $content, FILE_APPEND | LOCK_EX);
file_put_contents($filename, $content, FILE_APPEND);
得到的是相同的结果,并没有发现丢失日志的情况

@cbasil 我是看 thinkphp5 的文件日志驱动类
```php
protected function write($message, $destination, $apart = false)
{
//检测日志文件大小，超过配置大小则备份日志文件重新生成
if (is_file($destination) && floor($this->config['file_size']) <= filesize($destination)) {
rename($destination, dirname($destination) . DS . time() . '-' . basename($destination));
$this->writed[$destination] = false;
}

if (empty($this->writed[$destination]) && !IS_CLI) {
if (App::$debug && !$apart) {
// 获取基本信息
if (isset($_SERVER['HTTP_HOST'])) {
$current_uri = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
} else {
$current_uri = "cmd:" . implode(' ', $_SERVER['argv']);
}

$runtime = round(microtime(true) - THINK_START_TIME, 10);
$reqs = $runtime > 0 ? number_format(1 / $runtime, 2) : '∞';
$time_str = ' [运行时间：' . number_format($runtime, 6) . 's][吞吐率：' . $reqs . 'req/s]';
$memory_use = number_format((memory_get_usage() - THINK_START_MEM) / 1024, 2);
$memory_str = ' [内存消耗：' . $memory_use . 'kb]';
$file_load = ' [文件加载：' . count(get_included_files()) . ']';

$message = '[ info ] ' . $current_uri . $time_str . $memory_str . $file_load . "\r\n" . $message;
}
$now = date($this->config['time_format']);
$server = isset($_SERVER['SERVER_ADDR']) ? $_SERVER['SERVER_ADDR'] : '0.0.0.0';
$remote = isset($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : '0.0.0.0';
$method = isset($_SERVER['REQUEST_METHOD']) ? $_SERVER['REQUEST_METHOD'] : 'CLI';
$uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
$message = "---------------------------------------------------------------\r\n[{$now}] {$server} {$remote} {$method} {$uri}\r\n" . $message;

$this->writed[$destination] = true;
}

if (IS_CLI) {
$now = date($this->config['time_format']);
$message = "[{$now}]" . $message;
}

return error_log($message, 3, $destination);
}

```
最后也是用 error_log 写入的，但是我就是 TP5 提供的 sql.log 日志,也漏某一个时刻的

我添加一些详细的信息,服务器是 2 核心，4GB，40GB 硬盘。系统是 CentOS 7.7.1908,运行环境是宝塔,而且有一个 Mysql 表会不断更新硬件心跳,250 台机器左右,每 40s 会更新一次心跳。但平时用户比较少,只有晚上高峰期才会出现不同用户在同一时刻下单,而且现在用户才 2000 个,怎么也想不出这点用户,会在哪里情况下某时刻日志会丢的。
然后我通过命令查看`pidstat -d 1`查看平时的 IO
