问题描述

在将文档插入任何分片集合时,我收到错误“如果不以 --shardsvr 开头,则无法接受分片命令”。

我的设置就像

rs0:mongon1,mongon2,mongon3

rs1: mongon4, mongon5, mongon6 在端口 27017

配置:mongoconf1、mongoconf2、mongoconf3 都在端口 27019

mongos 上的 mongos:27017 在 mongos 服务器上使用以下命令成功启动 mongos

mongos --configdb configReplSet/mongoconfs1:27019,mongoconfs2:27019,mongoconfs3:27019

以下是我的分片状态

请帮助我确定我哪里出错了。

解决方案


我发现了插入的问题。我使用的是mongodb.conf文件,在这些配置文件中我必须提到分片:节点的详细信息是分片集群的一部分。我错过了在属于分片集的所有 mongod 服务器的 mongod.conf 文件中输入分片详细信息。

我所有的 mongod 节点都应该在 mongod.conf 文件的 ** sharding** 部分中包含以下内容。

#sharding:
sharding:
  clusterRole: shardsvr
