根因分析

客户端发送了一个 Redis 命令表中不存在的命令，通常是由于拼写错误或使用了其他数据库（如 PostgreSQL 的 FORK）的命令。

English

A client sent a command that does not exist in the Redis command table, often due to a typo or using a command from a different database (e.g., PostgreSQL FORK).

解决方案

  1. Check the application code for the exact command string and replace it with the correct Redis command. For example, change `FORK` to `BGSAVE` if the intent was to fork a background save.
  2. Use Redis' `COMMAND INFO` to verify the command exists: `redis-cli COMMAND INFO FORK` returns empty if unknown.
  3. If the command is from a third-party library, update the library to use Redis-compatible commands. Example in Python: `r.execute_command('BGSAVE')` instead of `r.execute_command('FORK')`.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The command name is still not recognized as a built-in Redis command.

  2. 99% 失败

    Redis command set is fixed and not configurable.
