好了废话不多说本着解决问题的实事求是的踩坑心得分享解决问题

 问题点一就是redis的配置文件问题

使用vim编辑器修改`bin`目录中的redis.conf文件,修改如下三项

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens # for connections from all the network interfaces available on the server. # It is possible to listen to just one or multiple selected interfaces using # the "bind" configuration directive, followed by one or more IP addresses. # # Examples: # # bind 192.168.1.100 10.0.0.1　　　　　　　这里是告诉我们可以绑定多个ip来连接redis服务端 # bind 127.0.0.1 ::1 # # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the # internet, binding to all the interfaces is dangerous and will expose the　翻译一下大概就是注意：如果redis直接暴露在互联网，绑定所有接口是非常危险的，因此我们没有注释下面的绑定指令

# instance to everybody on the internet. So by default we uncomment the　　　　　　　　

bind 127.0.0.1　　这个相当于只绑定在服务端本地，也就是说只能在服务端连接redis，进行操作

# following bind directive, that will force Redis to listen only into # the IPv4 lookback interface address (this means Redis will be able to # accept connections only from clients running into the same computer it # is running). # # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES　　　　如果你想要开放所有ip接口，注释下面这行 # JUST COMMENT THE FOLLOWING LINE. # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #bind 127.0.0.1

就直接注释bind 127.0.0.1，重启一下让配置生效，再进行远程连接就ok了。

其次还有就是 protected-mode保护模式改为no,接着 daemonize 修改为yes保存好设置，重启如果

重启可以连接成功，下面的可以不用看了。

接下来大概率就是防火墙没有打开6379的端口，进入shell工具查看Linux系统虚拟机的IP地址

ifconfig可以看到VM虚拟机的IP

inte 后面的就是IP地址，这时候打开win+R输入cmd命令，通过telnet命令，测试端口是否畅通。如果连接失败,表示CentOS的6379端口没有开启。

开启端口成功之后再用cmd命令重复上述telnet命令一遍，出现小黑框闪烁一下说明连接没有问题。

最后开启redis desktop manager（可视化工具）,auth为redis密码,可以设置,也可以不设置，但是提个醒在云服务器上安装redis最好设置密码,设置密码和绑定ip,二选一即可,否则redis处于保护模式,只能本虚拟机访问
