MongoDB is a product between a relational database and a non-relational database, and is the most versatile and most like relational database in a non-relational database. The data structure he supports is very loose and is a JSON-like Bjson format, so you can store more complex data types. MONGO's biggest feature is that the query language he supports is very powerful, and its syntax is a bit like an object-oriented query language that almost implements most of the functionality of a relational database single-table query, and also supports indexing of data.
MongoDB is one of the NoSQL, and as more and more companies use the product, has begun to gradually replace the status of some high-performance queries.
It is characterized by high performance, easy to deploy, easy to use, and easy to store data. The main features are:
For collection storage, easy to store data for object types.
Mode of freedom.
Supports dynamic queries.
Supports full indexes, including internal objects.
Support Queries.
Supports replication and recovery.
Use efficient binary data storage, including large objects such as video.
Automatically process fragmentation to support scalability at the cloud level
Supports multiple languages such as ruby,python,java,c++,php.
File storage format is Bson (an extension of JSON)
Accessible over the network
######### installation Process ##########
1, go to the website of MongoDB Direct download, here we download the version of 3.0.3.

The Mongod under the bin is the service-side process of MongoDB, MONGO is its client, and other commands are used for MongoDB for other purposes such as MongoDB file export.
2, start MongoDB, to first establish a good MongoDB storage data files and log files directory:
[[email protected] mongodb]# pwd/mysqldata/mongodb[[email protected] mongodb]# lltotal 8drwxr-xr-x 2 root root 4096 June 15 14:27 db# Storage of DB data drwxr-xr-x 2 root root 4096 June 14:28 log# store mongodb log files [[email protected] mongodb]# CD Log[[email Protected] log]# Pwd/mysqldata/mongodb/log[[email protected] log]# lltotal 4-rw-r--r--1 root root 2440 June 15:06 Mong odb.log-rw-r--r--1 root root 0 June 15:05 mongodb.log.2015-06-15t07-06-06
3, in the MongoDB installation directory under the bin using Mongod to start MongoDB;
[[email protected] mongodb]# cd bin/[[email protected] bin]# lltotal 116340-rwxr-xr-x 1 1046 1046 4305912 may 12 05:35 Bsondump-rwxr-xr-x 1 1046 1046 11694552 may 12 05:43 mongo-rwxr-xr-x 1 1046 1046 22349960 may 12 05:43 mongod-rwxr-xr-x 1 1046 1046 6199144 may 12 05:35 mongodump-rwxr-xr-x 1 1046 1046 6001840 May 12 05:35 mongoexport-rwxr-xr-x 1 1046 1046 5956232 May 12 05:35 mongofiles-rwxr-xr-x 1 1046 1046 6211952 may 12 05:35 mongoimport-rwxr-xr-x 1 1046 1046 5686856 May 12 05:35 mongooplog-rwxr-xr-x 1 1046 1046 22129448 May 12 05:43 mongoperf-rwxr-xr-x&Nbsp;1 1046 1046 6332464 may 12 05:35 mongorestore-rwxr-xr-x 1 1046 1046 10552760 May 12 05:43 mongos-rwxr-xr-x 1 1046 1046 5909928 may 12 05:35 mongostat-rwxr-xr-x 1 1046 1046 5769944 may 12 05:35 mongotop[[email protected] bin]# ./mongod - -help# can use--help to view the Help documentation for MONGODB [[email protected] bin]# ./mongod --dbpath=/mysqldata/ mongodb/db/ --logpath=/mysqldata/mongodb/log/mongodb.log &[[email protected] log]# netstat -lanp | grep 27017tcp 0 0 0.0.0.0:27017 0.0.0.0:* listen 2661/./mongod unix 2 [ ACC ] stream listening 2420077 2661/./mongod /tmp/mongodb-27017.sock
4, you can see, started successfully, and now use the MONGO client access to the database, see the following is the start of the success (if there are some warnings do not matter)

The use of various commands of MongoDB we can check on the Internet, there is a lot of information, and written in very detailed.
