如何连接到部署在Google Cloud上的redis？ [英] How to connect to redis deployed on Google Cloud?

问题描述

案例基础：
在Google Cloud中部署了一个redis实例（单实例）。使用基于NodeJS的服务器和redis-sentinel库连接到节点。原因是在Google Cloud上基于标记的节点管理。

我可以通过仪表板/控制台的SSH登录登录redis实例。使用redis-cli连接到redis的本地运行服务，并可以创建/编辑各种数据集。

问题：当我尝试通过本地主机或任​​何其他计算机访问它时实例部署在同一个项目域中。我使用公共IP和端口26379/6379进行连接，但连接被拒绝。

可能的原因：

• 网络访问政策。

解决方案

上周为自己起见，想分享我在这里学到的教训。希望这是有帮助的，即使这已经晚了近一年：）

我使用的是点击部署方案，发现这里（Redis by Redis，而不是Bitnami），它允许奇数个虚拟机作为群集。

创建部署后，我必须在每个虚拟机上执行以下手动步骤以使其可用作哨兵集群：

• redis-cli 并运行 CONFIG SET保护模式no 和 CONFIG REWRITE 。这会将redis服务器暴露给外部连接。

>并添加保护模式否，所以哨兵也可以互相连接 c> sudo /etc/init.d/redis-sentinel start 启动sentinel服务



• redis-cli -p 26379 并通过运行 sentinel ckquorum master 来检查sentinel状态。预计会看到'OK X可用的Sentinels'，X表示您在群集中拥有的虚拟机数量。

剩菜：

• redis-sentinel 不作为服务运行。需要添加到 /etc/rc?.d 旁边 redis-server


• /etc/init.d/redis- {server，sentinel} 不会被编写为正确的Debian服务，因此一旦死亡就不会重新生成。

总体而言，该产品非常失望，期待更完整的设置。

Case Basics: Deployed a redis instance (single instance) in Google Cloud. Using NodeJS based server and redis-sentinel library to connect to the node. Reason being sentinel based management of nodes on google cloud.

I can login in the redis instance via dashboard/console's SSH login. Connect to the local running service of redis using redis-cli and can create/edit various datasets.

Issue: When i try to access it via my localhost or any other compute instance deployed within the same project domain. I am using public ip and port 26379/6379 for the connection but connection is being refused.

Possible reasons:

• Network access policies.

解决方案

Struggled to set this up for myself last week, wanted to share the lessons I learnt here. Hope this is helpful, even if this is almost a year late :)

I was using a click-to-deploy scheme found here (Redis by Redis, not Bitnami), which allows an odd number of VMs to serve as a cluster.

Once the deployment is created, I had to perform the following manual steps on each VM to make it usable as a sentinel cluster:

• redis-cli and run CONFIG SET protected-mode no and CONFIG REWRITE. This will expose the redis server to external connections.

• sudo vi /etc/redis/sentinel.conf and add protected-mode no so sentinels can also connect to each other

• sudo /etc/init.d/redis-sentinel start to start the sentinel service

• redis-cli -p 26379 and check sentinel status by running sentinel ckquorum master. Expect to see 'OK X usable Sentinels', X being the number of VMs you have in the cluster.

Leftovers:

• redis-sentinel DOES NOT run as a service. Need to be added to /etc/rc?.d alongside redis-server
• /etc/init.d/redis-{server,sentinel} are not written as proper Debian services, hence they do not respawn once killed.

Overall very disappointed in this offering, was expecting a more finished setup.
