MongoDB Learning Notes-database installation and configuration

MongoDB Database Installation

MongoDB official: Https://www.mongodb.com/download-center

You first need to choose the correct version of MongoDB based on the version of Windows to install, and you can check the Windows version by entering the following instruction on the command line:

WMIC OS get Osarchitecture

+ -bit version of MongoDB only support 2G The following databases are available for testing and evaluation only.

Click on the downloaded installation file to proceed MongoDB database installation, such as: Mongodb-win32-x86_64-2008plus-ssl-3.2.10-signed.msi

after the installation is complete, jump to the command line MongoDB installation directory, enter the following command to check if the installation was successful

Mongod-v

MongoDB needs to create a directory to hold all the data files, by default MongoDB data directory is C:\data\db\ (see above), so you need to create the corresponding folder under the C drive, you can also set the command line

MongoDB's Data Directory

mongod --dbpath "d:\mongodb\data" 

The console output is displayed ? waiting for connections? message, which means Mongod The process has run successfully.

There are 2 ways to start MongoDB, one is to specify the configuration parameters directly, and the other is to specify the configuration file

2. Specify configuration parameters directly

   For example:

   mongod --dbpath "d:\mongodb\data" 

3. Specify the configuration file

   Because there is no default configuration file in the official download installation package,If you want to use a configuration file that you can create only yourself, make sure to useASCIIencoding format,Mongod?instance does not support configuration files using non-ASCII?encoding format, includingUTF-8. From2.6version laterMongoDBUseYAMLfile format, note: YAML? tab Indent is not supported:?Replace with a space.

   For example:

   mongod --config d:\mongodb\mongodb.conf

?

Detailed configuration parameters:

? MongoDB 3.0The configuration file then takesYAMLformat, this format is very simple, using the<key>:<value>indicates that the beginning is used"Space"as indentation. It is important to note that":"Then there arevaluewords that need to be followed by a space ifKeysimply represents a hierarchy, you do not need to":"add spaces (such as:Systemlog:There are no spaces to be followed.) By hierarchy, each line4a space indent, and the second level8spaces, which are pushed in turn, and the top layer does not require a space indent

1. Systemlog

Systemlog.verbosity

Systemlog.logrotate

String

New in V3.0.0 version, default value is rename

Use Rename,mongod or MONGOs to rename the current log file by adding a UTC (GMT) timestamp to the end of the file name, then open the new log file, close the old log file, and send all new log information to the new log file.

Reopen close and reopen the log file follows typical Linux/unix log switching behavior. Use reopen to avoid log loss when using the Linux/unix logrotate tool.

If you specify reopen, you must also use-logappend

?

Storage.preallocdatafiles

Boolean, Default True

Whether to pre-shard good data files.

Storage.nssize

Storage.journal.commitIntervalMs

Number, default is 100 or 30

The maximum time interval for journal operations. Can be a value between 2-300ms, a low value helps to persist, but increases the additional burden on the disk.

If the journal and data files are on the same disk, the default is 100ms. If the 30ms is on a different disk.

If you force Mongod to commit the log file, you can specify J:true, and the time becomes the original one-third.

?

MONGOs only option

Replication.localpingthresholdms

Integer, default 15

Affected when the client selects the replica set for read operations.

Sharding.autosplit

Boolean

Prevents MONGOs from automatically inserting metadata in a shard collection.

Because any mongos can create a separation, if this option is turned on, it will result in fragmentation of the Shard and need to be used with caution.

Sharding.configdb
