mongodb - 在特定的 mongodb 设置中部署 fiware-orion

标签 mongodb fiware-orion

我使用 mongodb 分片并通过 docker 进行复制。 (3 个虚拟机托管 15 个容器)。我的 Mongodb 集群功能齐全。

现在我尝试在其上连接 Orion CB。通常我必须将它连接到 Mongo 路由器，但它不起作用。

我的 orion 容器正在运行，但是当我查看日志时，我只有该信息:

docker logs -f STC-orion_orion1.1.iiv0xf6qe4pco4fk679b1s3i9 time=Wednesday 28 Feb 14:07:47 2018.732Z | lvl=ERROR | corr=N/A | trans=N/A | from=N/A | srv=N/A | subsrv=N/A | comp=Orion | op=mongoConnectionPool.cpp[195]:mongoConnect | msg=Database Startup Error (cannot connect to mongo - doing 100 retries with a 1000 microsecond interval)

感谢您的帮助

最佳答案

我不是分片方面的专家，也从未使用 Orion 进行过测试，但从技术上讲，@fgalan 是正确的。

当您使用 mongo 分片时，访问将通过充当路由器的 mongos 进行，即它们通过配置服务器了解将写入和读取路由到正确的分片集群，这也意味着它们处理与分片副本的连接为访问路由器的客户端设置。所以你不需要指定任何副本集，你只需要列出你想要连接的路由器(这可能会由驱动程序通过循环方法选择，但我不确定，你应该检查 C++ 旧版驱动程序实现验证)。

顺便说一句，路由器是一个 headless 服务，所以(假设您正在使用堆栈部署)我将有一个可以上下扩展的服务，这样您就不需要在前面放置负载均衡器(诚实地测试)

为了拥有更可配置/可扩展的 docker 服务，您可以调整我们在这里所做的工作:

当然，如果您愿意，请随意提出拉取请求。
