windows 下 redis服務經常自動關閉

記一次線上服務器redis 經常掉線的問題

環境: windows service 2019, redis, java8,
由於服務器資源有限, 項目的數據庫oracle, 緩存數據庫redis和web服務tomcat都在同一個台服務器部署
問題描述:
在使用會經常報錯 redis pool無可用連接, 各種調試后發現是redis無法釋放, 后來手動在自己封裝的redisUtil工具類 每次調用redisTemplate.expire(key, time, TimeUnit.SECONDS);等方法時,用try,finally包裹,
finally里添加RedisConnectionUtils.unbindConnection(redisTemplate.getConnectionFactory());釋放redis連接資源語句,例如:

public long getExpire(String key) {
        Long expire;
        try {
            expire = redisTemplate.getExpire(key, TimeUnit.SECONDS);
        } finally {

            RedisConnectionUtils.unbindConnection(redisTemplate.getConnectionFactory());
        }
        return expire;
    }

線上會經常不定時出現redis連接超時問題

半天時間一直等這個問題出現, 發現是redis服務停止

查看redis日志server_log.txt

明白了EndForkOperation: 0x00000005 - EndForkOperation:的意思是, 因為序列化的子程序停止,導致redis主程序停止

那么為什么序列化會停止?

安裝redis服務使用的是msi安裝包, 安裝后會自動配置redis服務, 並且配置了服務停止后自動重啟服務.
問題就在這里, 在redis序列化的時候,被windows認為是假死狀態, 自動停掉的redis服務, 並一分鍾后重啟

這也解釋了

解決辦法:

1. 不使用windows服務的功能, 使用zip壓縮包, 既不注冊redis服務, 使用黑窗口的形式運行redis
2. 關閉redis服務模式, 自動改為手動
