2.1. Quickstart

2.1.1. 二进制tar包安装

Install MongoDB

wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.5.5.tgz

debian:/srv# tar zxf mongodb-linux-x86_64-1.5.5.tgz
debian:/srv# ln -s mongodb-linux-x86_64-1.5.5 mongodb
			

Create a data directory

By default MongoDB will store data in /data/db, but it won't automatically create that directory. To create it, do:

$ sudo mkdir -p /data/db/
$ sudo chown `id -u` /data/db
			

You can also tell MongoDB to use a different data directory, with the --dbpath option.

Run and connect to the server

First, start the MongoDB server in one terminal:

$ ./mongodb/bin/mongod
			

In a separate terminal, start the shell, which will connect to localhost by default:

$ ./mongodb/bin/mongo
> db.foo.save( { a : 1 } )
> db.foo.find()
			

Congratulations, you've just saved and retrieved your first document with MongoDB!

Starting Mongo

Running as a Daemon

 $ ./mongod --fork --logpath /var/log/mongodb.log --logappend
			

2.1.2. Ubuntu MongoDB

$ sudo apt-get install mongodb-server mongodb-clients
			
$ /etc/init.d/mongodb
Usage: /etc/init.d/mongodb {start|stop|force-stop|restart|force-reload|status}
			

2.1.3. CentOS MongoDB

CentOS 默认 MongoDB 是 2.6.12

[root@iZ623h9icu8Z ~]# yum info mongodb
Loaded plugins: langpacks
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Available Packages
Name        : mongodb
Arch        : x86_64
Version     : 2.6.12
Release     : 3.el7
Size        : 43 M
Repo        : epel/x86_64
Summary     : High-performance, schema-free document-oriented database
URL         : http://www.mongodb.org
License     : AGPLv3 and zlib and ASL 2.0
Description : Mongo (from "humongous") is a high-performance, open source, schema-free
            : document-oriented database. MongoDB is written in C++ and offers the following
            : features:
            :     * Collection oriented storage: easy storage of object/JSON-style data
            :     * Dynamic queries
            :     * Full index support, including on inner objects and embedded arrays
            :     * Query profiling
            :     * Replication and fail-over support
            :     * Efficient storage of binary data including large objects (e.g. photos
            :     and videos)
            :     * Auto-sharding for cloud-level scalability (currently in early alpha)
            :     * Commercial Support Available
            : 
            : A key goal of MongoDB is to bridge the gap between key/value stores (which are
            : fast and highly scalable) and traditional RDBMS systems (which are deep in
            : functionality).
