Redis is running in protected mode because protected mode is enab led

(error) DENIED Redis is running in protected mode because protected mode is enab
led, no bind address was specified, no authentication password is requested to c
lients. In this mode connections are only accepted from the loopback interface.
If you want to connect from external computers to Redis you may adopt one of the
following solutions: 1) Just disable protected mode sending the command ‘CONFIG
SET protected-mode no’ from the loopback interface by connecting to Redis from
the same host the server is running, however MAKE SURE Redis is not publicly acc
essible from internet if you do so. Use CONFIG REWRITE to make this change perma
nent. 2) Alternatively you can just disable the protected mode by editing the Re
dis configuration file, and setting the protected mode option to ‘no’, and then
restarting the server. 3) If you started the server manually just for testing, r
estart it with the ‘–protected-mode no’ option. 4) Setup a bind address or an a
uthentication password. NOTE: You only need to do one of the above things in ord
er for the server to start accepting connections from the outside.

解决方案：
在redis的home目录下的sentinel.conf中加上protected-mode no 即可
