一：问题如下
[sql] view plain copy
在192.168.56.57客户端登录192.168.56.56的redis服务器时，报错如下：
[root@localhost src]# ./redis-cli -h 192.168.56.56 -p 6379 -a"aabbcc"
192.168.56.56:6379> ping
Error:Connection reset by peer
再telnet一下192.168.56.56的redis服务器的6379端口,提示redis服务有保护模式,需要解除
[root@localhost src]# telnet 192.168.56.56 6379
Trying 192.168.56.56...
Connectedto 192.168.56.56.

DENIED Redisis running in protected modebecause protected mode is enabled, no bind address was specified, noauthentication password is requested to clients.
In this mode connections areonly accepted from the loopback interface. If you want to connect from externalcomputers to Redis you may adopt one of the following
solutions: 1) Justdisable protected mode sending the command'CONFIG SET protected-mode no' fromthe loopback interface by connecting to Redis from the same host
the server isrunning, however MAKE SURE Redisis not publicly accessible from internet ifyou do so. Use CONFIG REWRITE to make this change permanent.
2) Alternativelyyou can just disable the protected modeby editing the Redis configurationfile, and setting the protected mode option to 'no', and then restarting theserver.
3) If you started the server manually justfor testing, restart it withthe '--protected-mode no' option.
4) Setup a bind addressor an authenticationpassword. NOTE: You only need to do one of the above things in order for theserver to start accepting connections from the outside.
Connection closed by foreign host.
二：解决方案
[sql] view plain copy
1、修改redis服务器的配置文件
vi redis.conf
注释以下绑定的主机地址
# bind 127.0.0.1
2、修改redis服务器的参数配置
修改redis的守护进程为no ，不启用
127.0.0.1:6379> configset daemonize "no"
OK
修改redis的保护模式为no，不启用
127.0.0.1:6379> configset protected-mode "no"
OK
三：问题解决
[sql] view plain copy
再次telnet一下192.168.56.56的redis服务器的6379端口，无问题
[root@localhost Packages]# telnet 192.168.56.56 6379
Trying 192.168.56.56...
Connectedto 192.168.56.56.
Escape character is '^]'.
再次在192.168.56.57客户端登录192.168.56.56的redis服务器，无问题
[root@localhost src]# ./redis-cli -h 192.168.56.56 -p 6379 -a"aabbcc"
192.168.56.56:6379> ping
