webman使用GatewayWorker,過一段時(shí)間Redis報(bào)錯(cuò)

黑老怪

問題描述

運(yùn)行過一段時(shí)間就提示這個(gè),這是被Redis回收了鏈接嗎?

Workerman Redis Connection Error 2 client closed

Redis 配置限制：
Redis 最大連接數(shù)（maxclients）已滿，新連接被拒絕后關(guān)閉。
Redis 超時(shí)設(shè)置（timeout）過短，空閑連接被服務(wù)器主動(dòng)關(guān)閉。
檢查 Redis 日志（通常在 redis.conf 中配置的 logfile 路徑），確認(rèn)是否有崩潰、內(nèi)存溢出（OOM）等異常。

maxclients 100000  # 根據(jù)服務(wù)器內(nèi)存調(diào)整
timeout 0  # 禁用自動(dòng)關(guān)閉空閑連接（推薦）

優(yōu)化 Workerman 客戶端連接管理
Workerman 的 Redis 客戶端支持連接斷開后自動(dòng)重連，需在初始化時(shí)配置 reconnect 參數(shù)：

$redis = new Client([
    'host' => '127.0.0.1',
    'port' => 6379,
    'reconnect' => 3,  // 連接斷開后重試 3 次（每次間隔 1 秒）
]);

避免頻繁創(chuàng)建連接：
確保 Redis 客戶端實(shí)例被復(fù)用（如全局單例），而非每次請(qǐng)求創(chuàng)建新連接，減少連接開銷：

// 單例模式示例
class RedisClient {
    private static $instance;
    public static function getInstance() {
        if (!self::$instance) {
            self::$instance = new \Workerman\Redis\Client([
                'host' => '127.0.0.1',
                'port' => 6379,
            ]);
        }
        return self::$instance;
    }
}

// 使用時(shí)
$redis = RedisClient::getInstance();

檢查 Workerman 與 PHP 環(huán)境
更新 Workerman 及 Redis 客戶端：
舊版本可能存在連接處理 Bug，升級(jí)到最新穩(wěn)定版：

composer update workerman/workerman workerman/redis
