我已经安装了http://rediscart-claytondev.rhcloud.com/build/manifest/redis-2.8墨盒并将其缩放到 3 个齿轮。每个REDIS_SENTINEL_QUORUM都设置为 2。在我更改了~/redis/bin/controlfrom 后，哨兵启动正常：

erb conf/redis-sentinel.conf.erb | redis-server conf - --sentinel

至：

erb conf/redis-sentinel.conf.erb > conf/redis-sentinel.conf
redis-server conf/redis-sentinel.conf --sentinel

现在，重新启动墨盒后，它看起来没问题，直到我杀死主人。奴隶们只是坐在那里数秒，因为他们最后一次看到它......他们的（其中一个）日志说：

查看您的配置，您有使用相同名称的哨兵和 Redis 实例。他们还共享导致混乱的日志文件。这不是你想要的。

你要：

3 个具有唯一名称的哨兵实例。

一个 Redis 主节点 + 一个 Redis 从节点（这是一个“Pod”，您将使用标识此组合的唯一名称来命名它 - 而不是其中的节点）。

您将其添加到您的哨兵设置中，并设置它的密码。假设您将 pod 命名为“pod1”，那么您的配置将如下所示：

sentinel monitor pod1 <master-ip> <master-port> 2
sentinel auth-pass <the-master-auth-pass-and-requirepass-setting>
sentinel down-after-milliseconds pod1 10000
sentinel parallel-syncs pod1 1
sentinel failover-timeout pod1 30000

虽然您可以为每个吊舱运行一个哨兵星座，但使用一个哨兵星座来管理多个吊舱会更有效。也不是您不希望这些哨兵与它们监视的 Redis 实例在同一主机上运行 - 否则在您最需要它们时可能会丢失它们。

不幸的是，我对 OpenShift 并不熟悉，所以我不知道您为它配置它所采取的路线。但是，知道配置应该是什么样子应该可以帮助您确认它是否正确。
