redis关闭保护模式

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...  
Connected to 192.168.56.56.  
Escape character is ‘^]‘.  
  
-DENIED Redis is 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 Redis is not publicly accessible from internet ifyou do so. Use CONFIG REWRITE to make this change permanent.   
2) Alternativelyyou can just disable the protected mode by editing the Redis configurationfile, and setting the protected mode option to ‘no‘, and then restarting theserver.   
3) If you started the server manually just for testing, restart it withthe ‘--protected-mode no‘ option.   
4) Setup a bind address or 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.  

修改redis的守护进程为no ，不启用  
127.0.0.1:6379> config set daemonize "no"  
OK  
  
修改redis的保护模式为no，不启用  
127.0.0.1:6379> config set protected-mode "no"  
OK  

1) 绑定IP地址,看业务开放
bind 0.0.0.0

2)Redis默认不是以守护进程的方式运行，可以通过该配置项修改，使用yes启用守护进程，设置为no

daemonize no

3)保护模式

protected-mode no
