Redis CLI 重命名 key - 错误未知命令使用参数重命名

Question

我有一个可以在本地运行的 redis-cli 脚本(从 Win10)，但是当我使用 rename 命令在服务器 (Linux) 上运行它时，它会失败。

与redis-cli(来自Win10)连接后，我运行以下命令:

SET "someinstance.domain.us:mytenant:MyDailyData:2018.1.10" "Hello123"
GET "someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
RENAME "someinstance.domain.us:mytenant:MyDailyData:2018.1.10" "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
DEL "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
GET "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"

虽然本地一切正常，但当我对服务器运行它时，我得到以下输出:

my-redis-address:6379> SET "someinstance.domain.us:mytenant:MyDailyData:2018.1.10" "Hello123"
OK
my-redis-address:6379> GET "someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
"Hello123"
my-redis-address:6379> RENAME "someinstance.domain.us:mytenant:MyDailyData:2018.1.10" "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"

(error) ERR unknown command `RENAME`, with args beginning with: `someinstance.domain.us:mytenant:MyDailyData:2018.1.10`, `TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10`,

my-redis-address:6379> DEL "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
(integer) 0
my-redis-address:6379> GET "TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10"
(nil)
my-redis-address:6379>

(错误)错误未知命令重命名，参数开头为:someinstance.domain.us:mytenant:MyDailyData:2018.1.10、TEMP:someinstance.domain.us:mytenant:MyDailyData:2018.1.10,

redis服务器详细信息:

gcc_version 5.4.0
os  Linux 4.4.0-176-generic x86_64
redis_build_id  452d9690a8de23a2
redis_mode  standalone
redis_version   5.0.7

我在这里做错了什么？是我在 Linux Redis 服务器上运行 Win10 cli 导致的吗？

谢谢!

结论

RENAME 命令已被重命名为服务器上无意义的名称。

解决方案

检查服务器上的redis.conf文件是否有rename-command RENAME xxx一行。如果有，注释掉并重启Redis服务器。(如果服务器在线，请先联系管理员)

来自redis.conf:

# It is possible to change the name of dangerous commands in a shared
# environment. For instance the CONFIG command may be renamed into something
# hard to guess so that it will still be available for internal-use tools
# but not available for general clients.
#
# Example:
#
# rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52
