根因分析

Redis 服务器突然关闭了连接，通常是由于超时设置、内存压力或网络不稳定。

English

The Redis server closed the connection abruptly, often due to timeout settings, memory pressure, or network instability.

解决方案

  1. Increase the Redis server's timeout setting (timeout 0) in redis.conf to prevent idle connections from being closed.
  2. Implement a retry mechanism in PHP with exponential backoff when a RedisException is caught.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Increasing PHP's default_socket_timeout in php.ini does not affect Redis socket timeouts, which are handled separately.

  2. 75% 失败

    Restarting only PHP-FPM without restarting Redis may not help if the Redis server itself is overloaded or has a high memory usage.

  3. 65% 失败

    Disabling persistence (redis.persistent) may reduce the frequency but does not address the root cause of connection drops.
