MongoDB Use DB Show dbs

MongoDB Common commands:

Switching between DBS with use Xxxdb

Then the operation is only for XXXDB;

Show DBS shows all databases

Show collections Display all collections

MongoDB database is generally installed under USR Local

./mongod--dbpath=/usr/local/mongodb/db--fork--logpath=/usr/local/mongodb/logs/1. Log

Enter the/usr/local/mongodb/bin directory to run./mongod Start MongoDB

Add various parameters behind MongoDB

For example:

Run./mongo The local database is connected by default and can be manipulated after entering the shell console mode

But start MongoDB to run in the background to add the--fork parameter

The parameters of other functions are remembered as double bars--

--dbpath--logpath LogPath parameter is followed by a directory plus a specific file or it will be an error

A common practice is to create a new mongodb.conf configuration file under the bin file

Configuration files are well configured.

dbpath=/usr/local/mongodb/dblogpath=/usr/local/mongodb/logs/mongodb.logport=27017 Fork=truenohttpinterface=true

Then set

Vi/etc/rc.d/rc.local

/usr/local/mongodb/bin/mongod--config/usr/local/mongodb/bin/mongodb.conf

You can turn it on and start.
