使用redis desktop manager 連結redis伺服器出現以下問題：

-DENIED Redis is running in protected mode because protected mode is enabled, no
 bind address was specified, no authentication password is requested to clients.
 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 follow
ing solutions: 1) Just disable protected mode sending the command 'CONFIG SET pr
otected-mode no' from the loopback interface by connecting to Redis from the sam
e host the server is running, however MAKE SURE Redis is not publicly accessible
 from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2
) Alternatively you can just disable the protected mode by editing the Redis con
figuration file, and setting the protected mode option to 'no', and then restart
ing the server. 3) If you started the server manually just for testing, restart
it with the '--protected-mode no' option. 4) Setup a bind address or an authenti
cation password. NOTE: You only need to do one of the above things in order for
the server to start accepting connections from the outside.

--說明：這是redis伺服器啟動了保護模式，因此需要先關閉保護模式，

1. 修改redis伺服器的配置檔案  
2. vi redis.conf    
3. 註釋以下繫結的主機地址  
4. # bind 127.0.0.1  
5. 2、修改redis伺服器的引數配置  
6. 修改redis的保護模式為no，不啟用  
7. protected-mode "no"
8. OK  
   

若是還連線不上，就先關閉防火牆：service iptables stop ,再重新連結。
