从您提供的 Redis 日志文件内容来看，这里记录了 Redis 服务器的一些关键操作和事件。以下是对日志中一些关键信息的解释：

  1. RDB 快照保存：

    • 26077:M 21 Jul 14:07:25.096 * 10 changes in 86400 seconds. Saving... 表示在 86400 秒内发生了 10 次数据变化，触发了 RDB 快照保存。
    • 10485:C 21 Jul 14:07:30.270 * DB saved on disk 表示数据库成功保存到磁盘。

  2. AOF 重写：

    • 26077:M 21 Jul 17:45:52.110 * Starting automatic rewriting of AOF on 100% growth 表示 AOF 文件由于增长了 100% 而触发了自动重写。
    • 10836:C 21 Jul 17:45:58.671 * SYNC append only file rewrite performed 表示 AOF 重写完成，并且使用了 SYNC 操作确保数据一致性。

  3. 客户端连接和关闭：

    • 26077:M 21 Jul 17:02:57.047 # Client id=62363 addr=10.193.48.197:45014 fd=257 name= age=113 idle=0 flags=N db=15 sub=1 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=16334 oll=3400 omem=28043184 events=rw cmd=unsubscribe scheduled to be closed ASAP for overcoming of output buffer limits. 表示一个客户端因为输出缓冲区限制而被计划关闭。

  4. 内存使用：

    • 10485:C 21 Jul 14:07:30.305 * RDB: 4 MB of memory used by copy-on-write 表示在 RDB 快照保存过程中使用了 4 MB 的内存进行写时复制。
    • 10836:C 21 Jul 17:45:58.712 * AOF rewrite: 20 MB of memory used by copy-on-write 表示在 AOF 重写过程中使用了 20 MB 的内存进行写时复制。

  5. AOF 重写完成：

    • 26077:M 22 Jul 09:43:51.401 * Background AOF rewrite finished successfully 表示 AOF 重写成功完成。

  6. RDB 快照和 AOF 重写触发条件：

    • 日志显示了多次 RDB 快照保存和 AOF 重写，这通常是由于数据变化触发的。例如，26077:M 22 Jul 12:56:09.636 * DB saved on disk 表示在 22 日 12:56 进行了 RDB 快照保存。

这些日志信息对于监控和维护 Redis 服务器非常重要，它们可以帮助您了解服务器的运行状态和性能。如果您需要进一步的帮助或有特定的问题，请告诉我。
