基于Phalcon的uniondrug/framework项目中，使用本应用服务器可以提高性能。
$ composer requre uniondrug/server
$ cp vendor/uniondrug/server/server.php.example config/server.php
$ php server --help

server.php 中配置的是Swoole服务器的运行参数，详细参数请参考swoole文档：
return [
'default' => [
'host' => 'https://0.0.0.0:9527',
'class' => \Uniondrug\Server\Servitization\Server\HTTPServer::class,
'options' => [
'pid_file' => __DIR__ . '/../tmp/pid/server.pid',
'worker_num' => 1,
'task_worker_num' => 1,
],
'processes' => [],
'listeners' => [
[
'class' => \Uniondrug\Server\Servitization\Server\ManagerServer::class,
'host' => 'tcp:https://0.0.0.0:9530',
],
],
],
'development' => [
'autoreload' => true,
'processes' => [
// 开发环境，自动监控文件改动，改动后自动Reload服务
\Uniondrug\Server\Processes\ReloadProcess::class,
],
],
'production' => [
'options' => [
'worker_num' => 5,
],
],
];Swoole的Worker会保持数据库的长连接，如果长时间服务器没有请求发生，可能会出现数据库服务器断开连接的情况。
可以通过在数据库的配置文件，增加一个参数，启动定时器来让worker进程与数据库服务器保持心跳。配置文件：database.php，配置参数 interval。参数为0时不启动定时器，大于0时，作为心跳间隔，单位：秒。
return [
'default' => [
'adapter' => 'mysql',
'debug' => true,
'useSlave' => false,
'interval' => 0,
'connection' => [
'host' => '127.0.0.1',
'port' => 3306,
'username' => 'root',
'password' => '',
'dbname' => 'dbname',
'charset' => 'utf8',
],
],
];
