居然报所有哨兵都down掉的错误，而我确认所有这些哨兵都正常着，百度看看，说是防火墙的问题。但是我的防火墙就没开，看来也不是这个问题。后来发现了上面打印的警告信息。

这是因为哨兵的配置文件里的保护模式启动了。所以又因为没有绑定可以访问的ip和设置访问密码，就不允许从外部访问。
我们的哨兵明明是127的地址，应该访问127.0.0.1:26379才对啊，这是因为redis内部把127的地址转换成了192.168.2.101了，也就是你的本机的ip地址。所以访问192的地址就相当于从外部访问你的哨兵。
根据它的1，2，3，4的提示，你只要满足其中一个就行。于是我就把三个哨兵的sentinel.conf配置文件中的保护模式改为禁用就行了
# *** IMPORTANT *** # # By default Sentinel will not be reachable from interfaces different than # localhost, either use the ‘bind‘ directive to bind to a list of network # interfaces, or disable protected mode with "protected-mode no" by # adding it to this configuration file. # # Before doing that MAKE SURE the instance isprotectedfrom the outside # world via firewalling or other means. # # For example you may use one of the following: # # bind 127.0.0.1192.168.1.1 # protected-mode no
这样再访问就ok了。
