本文主要是介绍基于easyswoole实现的redis连接池，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
/*** Class MysqlPoolService mysql连接池* @package App\Service*/
class MysqlPoolService
{use Singleton;protected $config;protected $pool;protected $min = 5;protected $defaultSize = 100;protected $max = 1000;protected $timeout = 0.1;protected static $links = [];/*** MysqlPoolService constructor.* @throws Exception*/protected function __construct(){$this->config = Config::getInstance()->getConf('MYSQL-POOL');if (empty($this->pool)) {$this->defaultSize = $this->config['master']['pool_max_size'];$this->min = $this->config['master']['pool_size'];$this->timeout = $this->config['master']['pool_get_timeout'];$this->pool = new Channel($this->max);for ($i = 0; $i < $this->min; $i++) {$this->add($this->getMysql());}\EasySwoole\Component\Timer::getInstance()->loop(5 * 60 * 1000, function (){// todo 回收过多的老进程$this->recycle();});}}/*** @return MySQL* @throws Exception*/protected function getMysql(): MySQL{if(count(self::$links) > $this->max){throw new Exception('mysql connects too many!');}$mysql = new MySQL();$config = $this->config['master'];$config['time'] = microtime(true);$rs = $mysql->connect($config);if($rs == false){throw new Exception('mysql connect error!');}self::$links[$mysql->sock] = $mysql;return $mysql;}/*** 回收闲置连接*/protected function recycle(){while (count(self::$links) > $this->defaultSize){/*** @var MySQL $mysql*/$mysql = $this->pool->pop($this->timeout);if($mysql){$sock = $mysql->sock;defer(function()use($mysql){if(!empty($mysql) && $mysql->connected){$mysql->close();
// echo "recycle-mysql\n";}});unset(self::$links[$sock]);}}}/*** 入池* @param MySQL $mysql*/protected function add(MySQL $mysql){$this->pool->push($mysql,$this->timeout);}/*** 获取连接** @return MySQL* @throws Exception*/public function get(): MySQL{$length = $this->pool->length();// 追加到默认值if($length <= $this->min){$this->add($this->getMysql());}/*** @var MySQL $mysql*/$mysql = $this->pool->pop($this->timeout);// 超时无法获取连接，追加连接if(empty($mysql)){$mysql = $this->getMysql();$this->add($mysql);}// 连接断开，加入新连接if (empty($mysql->connected)) {$mysql = $this->getMysql();}// 处理结束之后，回收连接defer(function () use ($mysql) {$this->add($mysql);});return $mysql;}
}
大概按自己的思路处理了，希望大佬指出不足，以加以完善。
