Command在Mongodb中是一类特殊操作,它提供了强大的管理及各项操作(比如建库,索引,删除集合等)。可以说通过Command可以完成几乎所有想做的事情。同时Mongodb开发者在Command上又做了非常清晰体系架构和设计,便于管理和高效执行各种类型的Command。 Command体系 为了对其中大部分command对一个大致的了解,我们可以用下面指令来...

I have done all things. I set the path variable to the bin and deleted and reinstalled MongoDB multiple times. but mongobd/mongo command is not working in my cmd. rather mongod work perfectly. please help me to fix it. …
Command line tools are a great way to enhance productivity, automate tasks using scripts, and perform multiple tasks using a single script or command. MongoDB provides an exhaustive set of tools for managing various MongoDB deployments in a more efficient way through thecommand line interface. Mon...

② mongod操作命令:客户端可以通过mongod复制集和cfg server访问集群的相关命令。 ③ MongoDB集群内部命令:mongos、mongod、mongo-cfg集群实例之间交互的命令。 Command命令处理模块核心代码实现如下: 《Command命令处理模块源码实现》相关文章重点分析命令处理模块核心代码实现,也就是上面截图中的命令处理源码文件实现。
$this->cmd["flags"] = (int)$flags; } function getCommand() { return new MongoDB\Driver\Command($this->cmd); } function getCollectionName() { return $this->cmd["create"]; }}$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"...
通过上面的几个核心接口实现,把mongos和mongod两个实例的服务入口与状态机SSM(ServiceStateMachine)联系起来,最终和下面的command命令处理模块关联。 dealTask进行一次mongodb请求的内部逻辑处理,该处理由_sep->handleRequest()接口实现。由于mongos和mongod服务入口分别由ServiceEntryPointMongos和ServiceEntryPointMongod两个...
