windows 下 redis服务经常自动关闭

记一次线上服务器redis 经常掉线的问题

环境: windows service 2019, redis, java8,
由于服务器资源有限, 项目的数据库oracle, 缓存数据库redis和web服务tomcat都在同一个台服务器部署
问题描述:
在使用会经常报错 redis pool无可用连接, 各种调试后发现是redis无法释放, 后来手动在自己封装的redisUtil工具类 每次调用redisTemplate.expire(key, time, TimeUnit.SECONDS);等方法时,用try,finally包裹,
finally里添加RedisConnectionUtils.unbindConnection(redisTemplate.getConnectionFactory());释放redis连接资源语句,例如:

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

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

线上会经常不定时出现redis连接超时问题

半天时间一直等这个问题出现, 发现是redis服务停止

查看redis日志server_log.txt

明白了EndForkOperation: 0x00000005 - EndForkOperation:的意思是, 因为序列化的子程序停止,导致redis主程序停止

那么为什么序列化会停止?

安装redis服务使用的是msi安装包, 安装后会自动配置redis服务, 并且配置了服务停止后自动重启服务.
问题就在这里, 在redis序列化的时候,被windows认为是假死状态, 自动停掉的redis服务, 并一分钟后重启

这也解释了

解决办法:

1. 不使用windows服务的功能, 使用zip压缩包, 既不注册redis服务, 使用黑窗口的形式运行redis
2. 关闭redis服务模式, 自动改为手动
