我可以更改 Redis 集群中正在執行的 Redis 實例的 MASTERAUTH 值嗎？

根據http://redis.io/topics/security，我可以在 Redis 配置文件中設置一個requirepass值，例如， 。requirepass foobared

但是，我不希望在我的配置文件中使用它。

基本上，我想將此密碼保留在.conf文件之外，並使用redis-cli.

################################## SECURITY ###################################

# Require clients to issue AUTH <PASSWORD> before processing any other
# commands.  This might be useful in environments in which you do not trust
# others with access to the host running redis-server.
#
# This should stay commented out for backward compatibility and because most
# people do not need auth (e.g. they run their own servers).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
# 2015.12.14 nbasanes: Although I prefer enabling this, I'm not 
# sure it buys us much, since a clear password in a config 
# file is bad for security:
# requirepass foobared

# 2015.12.14  nbasanes: This could be interesting, although 
#   I don't put much weight in security-by-obscurity:
# Command renaming.
#
# 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
#
# It is also possible to completely kill a command by renaming it into
# an empty string:
#
# rename-command CONFIG ""
#
# Please note that changing the name of commands that are logged into the
# AOF file or transmitted to slaves may cause problems.

是的，您確實可以requirepass在實時 Redis 實例上設置該值。

此範例顯示我在 Redis 從站上設置它：

[nbasanes@SLAVEONE ~]$ redis-cli -h $(facter ipaddress)
101.222.222.222:6379> CONFIG SET REQUIREPASS FOOBARED
OK
101.222.222.222:6379> CONFIG SET REQUIREPA FOOBARED
(error) NOAUTH Authentication required.
101.222.222.222:6379> AUTH FOOBARED
OK
101.222.222.222:6379> CONFIG SET REQUIREPA FOOBARED
(error) ERR Unsupported CONFIG parameter: REQUIREPA
10.252.226.179:6379> ROLE
1) "slave"
2) "101.102.94.22"
3) (integer) 6379
4) "connected"
5) (integer) 702567
101.222.222.222:6379>

是的，可以在執行時更改身份驗證。（請參閱 Nathan Basanese 的回答）。

此外，請確保觸發 config rewrite 命令以保持身份驗證。如果 Redis 實例重新啟動，它可能會失去

CONFIG REWRITE

您可以通過對您的 Redis 實例執行 CONFIG GET * 來獲取可以在執行時更改的所有參數的列表

 127.0.0.1:6379> CONFIG GET *
 1) "dbfilename"
 2) "dump.rdb"
 3) "requirepass"
 4) ""
 5) "masterauth"
 6) ""
 7) "unixsocket"
 8) ""
