# initAsynPools 用于初始化連接池，可以增加更多的連接池。 ```php /** * 這里可以進行額外的異步連接池，比如另一組redis/mysql連接 * @return array */ public function initAsynPools() { parent::initAsynPools(); $this->addAsynPool('redis2', new RedisAsynPool($this->config, 'test2')); } ``` 如上面代碼所展示我們增加了一個名為redis2的連接池。 RedisAsynPool的第一個參數傳遞我們的配置文件這里是$this->config，第二個參數傳遞的是配置中的目標名稱這里是test2。 ```php #redis.php文件 /** * 本地環境 */ $config['redis']['test']['ip'] = '192.168.21.10'; $config['redis']['test']['port'] = 6379; $config['redis']['test']['select'] = 1; $config['redis']['test']['password'] = '123456'; $config['redis']['asyn_max_count'] = 10; /** * 本地環境2 */ $config['redis']['test2']['ip'] = '192.168.21.10'; $config['redis']['test2']['port'] = 6379; $config['redis']['test2']['select'] = 2; $config['redis']['test2']['password'] = '123456'; $config['redis']['asyn_max_count'] = 10; ``` 這樣一來名為redis2的連接池所訪問的便是本地環境2所代表的redis連接了。 關于連接池還有2個方法 *addAsynPool [addAsynPool](/addasynpool.md) *getAsynPool [getAsynPool](/getasynpool.md)
