then request the active node for the most recent copy of the document affected by these operations. The node that is performing the resynchronization is considered a recovery and cannot be a candidate for the active node until this process is completed.Operation Command Line initialization operationSetting a replica set is a little more complicated than setting up a master-slave cluster. The first name of the replica set is to make it easy to differentiate it from other replica sets, and also t

to start MongoDB under the bin under the MongoDB installation directory, ./mongod--dbpath=/data/mongodb_data/--logpath=/data/mongodb_log/mongodb.log--logappend After you wait for the startup to succeed, you can see if the boot was successful, the default port number is 27017, and you can also specify an unused port at startup.Start by looking at the port number to see if MongoDB is started.

. If the journal is not turned on, the repair operation must be performed after the exception is restarted after the shutdown.remark:The MongoDB default database folder path is c:/data/db (note: Although it is the default, you need to create it yourself). However, you can also set the default path yourself, such as d:/test/data/db. You must create a storage folder for the database files before you start the MongoDB service, or you cannot start successfully. When using the system default folder p

you from manual sharding management.You need to use parts in the following situations:1. The server disk is not enough.2. A single Mongod cannot meet the performance requirements of Data Writing.3. Put big data into the memory to improve performance.For the partition structure we want to implement:We can see that the original Mongod node is divided into two parts: A and B. Route D reads and configures the

). -- Autoresync: If the slave node is not synchronized with the master node, the slave node is automatically synchronized again. -- Oplogsize: The oplog size of the master node (unit: MB ). Note: The operation records of the master node are called oplog. Oplog is stored in a special database called local. Oplog only records operations that change the database status. For example, query operations are not stored. 3. Command 1. Set the SQL code of the master node (IP: 10.0.0.1) Hww @ Ubuntu :

The simplest way to start, the foreground start, only specify the data directory, and use the default 27107

\Configure Environment Variables To facilitate MongoDB command operations, we also configure its environment variables. The operation is also very simple. Take Windows 7 as an example, computer-> right-click menu "properties" to open the "System Properties window"-> "Advanced System settings"-> "advanced" tab-> environment variables, add "D: \ mongodb \ bin" at the end of the path value of the system variable, save the variable, and re-open a command prompt window without entering D: the \ mong

Every time you start MongoDB will always receive the following unclean shutdown prompts, summed up the cause of the problem and the solution.

MongoDB is a database based on distributed file storage. Written by the C + + language. Designed to provide scalable, high-performance data storage solutions for WEB applications. MongoDB is a product between relational database and non relational database, and is the most powerful and relational database in the relational database. mongodb Download Address:http://www.mongodb.org/downloads 1.
