Mongo DB:无法在Ubuntu中创建分片集群

本文介绍了Mongo DB:无法在Ubuntu中创建分片集群的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经使用 docs.mongodb安装了MongoDB. org/manual/tutorial/install-mongodb-on-ubuntu/在我的Ubuntu机器上，并且mongo实例运行正常.

I have installed MongoDB using docs.mongodb/manual/tutorial/install-mongodb-on-ubuntu/ in my Ubuntu machine and the mongo instance is working fine.

我能够在实例中执行CRUD操作.我还安装了MonjaDB eclipse插件，并且能够查看其中的所有数据库/集合/文档.

I am able to do CRUD operations in the instance. I also installed the MonjaDB eclipse plugin and am able to see all databases/collections/documents in it.

现在，我想在我的机器上创建一个分片集群.我正在尝试以这种方式创建:

Now, I want to create a sharded cluster in my machine. I am trying to create this way:

cluster = new ShardingTest({"shards":3，"chunksize":1})

cluster = new ShardingTest({"shards" : 3, "chunksize" : 1})

出现以下错误: 重置数据库路径'/data/db/test0' 周三2月12 15:46:43错误:boost ::文件系统:: create_directory:权限被拒绝:"/data/db/test0"(匿名):1

It is giving the following error: Resetting db path '/data/db/test0' Wed Feb 12 15:46:43 Error: boost::filesystem::create_directory: Permission denied: "/data/db/test0" (anon):1

此外，我尝试为现有集合创建碎片.为此，首先我尝试在数据库中启用分片(测试")

Also, I tried to create shards for existing collection. For this, first I tried to enable sharding in my database ("test")

sh.enableSharding("test") 2月12日星期三15:48:14未捕获的异常:未连接到蒙哥斯

sh.enableSharding("test") Wed Feb 12 15:48:14 uncaught exception: not connected to a mongos

有人可以让我知道，怎么可能出问题了.

Can someone please let me know, what might went wrong.

预先感谢

推荐答案

我建议您遵循MongoDB网站上的文档来首次部署分片集群:

I can suggest that you follow the documentation from the MongoDB site to deploy your sharded cluster for the first time:

docs.mongodb/manual/tutorial/deploy -shard-cluster/

如果您随后希望通过另一种产品来帮助实现这一目标，那么您可以更加了解实际需要做的事情和没有发生的事情.

If you then wish to work through another product to aid in this then you can be more aware of what actually needs to be done and what is not happening.
