如果你在springboot整合linux上的redis时，其他配置都对了，但是访问时依然提示下面信息：

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

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 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 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 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, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

那就在Linux上启动redis时选择使用绝对路径试试，我就是各种尝试无效后，通过这种方式搞定的！特此记录，已备查用！

例如我的启动命令是下面这样：

[root@localhost fsrm]# /usr/local/redis/bin/redis-server  /home/fsrm/文档/redis.conf

之前怎么改都不生效，可能是启动时加载了默认redis.conf配置文件，导致不是以自己修改后的配置文件启动，所以任何改动都是没有意义的！

下面是Linux下使用redis时几个常用的命令

[root@localhost]# ps -ef | grep redis //查看redis进程信息
[root@localhost fsrm]# kill -9 XXXX  //杀死XXXX端口号对应进程

redis.conf配置文件里的几个配置项

# bind 127.0.0.1    //注释掉才能通过外网访问
daemonize yes       //以守护进程启动 默认时no        
protected-mode no   //取消保护模式 默认时yes开启

还有就是重启完redi后，springboot项目也要重启，否则不生效！
