# Coroutine\\Redis [TOC] > 推薦使用`Swoole\Runtime::enableCoroutine`\+ phpredis 或 predis 的 方式, 一鍵協程化原生PHP的redis客戶端使用, 減小開發成本. > > 4.2.6版本及以后不再需要手動安裝和啟用async-redis, 而是swoole自帶 * 需要安裝一個第三方的異步Redis庫[hiredis](https://github.com/redis/hiredis) ~~~ sudo make sudo make install sudo ldconfig ~~~ * 需要在編譯時增加`--enable-async-redis`來開啟此功能 * **請勿同時使用異步回調和協程`Redis`** ## 使用示例 * * * ~~~ $redis = new Swoole\Coroutine\Redis(); $redis->connect('127.0.0.1', 6379); $val = $redis->get('key'); ~~~ ## defer特性 ~~~ const REDIS_SERVER_HOST = '127.0.0.1'; const REDIS_SERVER_PORT = 6379; go(function () { $redis = new Swoole\Coroutine\Redis(); $redis->connect(REDIS_SERVER_HOST, REDIS_SERVER_PORT); $redis->setDefer(); $redis->set('key1', 'value'); $redis2 = new Swoole\Coroutine\Redis(); $redis2->connect(REDIS_SERVER_HOST, REDIS_SERVER_PORT); $redis2->setDefer(); $redis2->get('key1'); $result1 = $redis->recv(); $result2 = $redis2->recv(); var_dump($result1, $result2); }); ~~~ ## pipeline `Redis`服務器支持多條指令并發執行。可使用`defer`特性啟用`pipeline` ~~~ const REDIS_SERVER_HOST = '127.0.0.1'; const REDIS_SERVER_PORT = 6379; go(function () { $redis = new Swoole\Coroutine\Redis(); $redis->connect(REDIS_SERVER_HOST, REDIS_SERVER_PORT); $redis->setDefer(); $redis->set('key1', 'value'); $redis->get('key1'); $result1 = $redis->recv(); $result2 = $redis->recv(); var_dump($result1, $result2); }); ~~~ > `subscribe pSubscribe`無法用于defer(true)的情況。
