Linux, FreeBSD, Solaris, and OS X

First, ensure you have the required dependencies installed. We will assume a Fedora based operating system, but it should not be much different on your platform. OS X users often use

sudo yum install cyrus-sasl-devel

1, FreeBSD has

sudo yum install cyrus-sasl-devel

2, and Solaris has

sudo yum install cyrus-sasl-devel

sudo yum install git gcc automake autoconf libtool pkg-config

If you would like SSL support, make sure you have openssl installed.

sudo yum install openssl-devel

If you would like Kerberos support, make sure you have cyrus-sasl installed.

sudo yum install cyrus-sasl-devel

Now let's fetch the code, build, and install it. You may want to replace

sudo yum install cyrus-sasl-devel

4 and

sudo yum install cyrus-sasl-devel

5 with where you want the driver installed. The default is

sudo yum install cyrus-sasl-devel

6 and

sudo yum install cyrus-sasl-devel

7. However, many systems do not include this in

sudo yum install cyrus-sasl-devel

8 (or

sudo yum install cyrus-sasl-devel

9 in the case of OS X).

After running

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

0, you will see the newly generated

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

1 script. It is automatically run for you by

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

0. If you run

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

3, you can see the full set of options to customize your build for your exact requirements.

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

Windows

Install the dependencies for Windows. You will need

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

4 to fetch the code, and

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

5 to bootstrap the build. You will also need Visual Studio 2010 or newer. The free express version should work fine. The following assumes Visual Studio 2010.

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

Making a Connection

The mongo-c-driver provides a convenient way to access MongoDB regardless of your cluster configuration. It will handle connecting to single servers, replica sets, and sharded clusters.

In the following, we will create a new

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

6 that will be used to connect to

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

#include <mongoc.h>

int
main (int argc,
      char *argv[])
{
   mongoc_client_t *client;

   /* create a new client instance */
   client = mongoc_client_new ("mongodb://localhost:27017");

   /* now release it */
   mongoc_client_destroy (client);

   return 0;
}

And to compile it:

gcc -o test1 test.c $(pkg-config --cflags --libs libmongoc-1.0)

Alternatively, if you don't have

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

8 on your system, you can manually manage your include paths and libraries.

gcc -o test1 test.c -I/usr/local/include -lmongoc-1.0

It is important to note that creating a new instance of

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

6 does not immediately connect to your MongoDB instance. This is performed lazily as needed.

Connecting to a Replica Set

To connect to a replica set, specify the replica set name using the

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

0 URI option. You can also specify a seed list if you would like to be able to connect to multiple nodes in the case that one is down when initializing the connection.

mongoc_uri_t *uri = mongoc_uri_new ("mongodb://host1:27017,host2:27017/?replicaSet=mysetname");

Connecting to a Sharded Cluster

This is just like connecting to a replica set, but you do not need to specify a replica set name.

mongoc_uri_t *uri = mongoc_uri_new ("mongodb://host1:27017,host2:27017/");

Connecting to a Unix Domain Socket

You can specify a path to a Unix domain socket instead of an IPv4 or IPv6 address. Simply pass the path to the socket. The socket path MUST end in ".sock".

sudo yum install openssl-devel

Connecting to an IPv6 Address

The mongo-c-driver will automatically resolved IPv6 address from host names. But if you would like to specify the IPv6 address directly, wrap the address in

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

sudo yum install openssl-devel

Authentication

If you would like to use authentication with your MongoDB instance, you can simply provide the credentials as part of the URI string.

sudo yum install openssl-devel

SSL

To enable SSL from your client, simply add the

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

2 option to the URI.

sudo yum install openssl-devel

Kerberos

If you are one of the people on planet Earth lucky enough to use Kerberos, you can enable that simply with the following URI. Note the escaping of the principal as it would duplicate the

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

3 sign in the URI.

sudo yum install openssl-devel

Additional Connection Options

See the full variety of connection URI options at http://docs.mongodb.org/manual/reference/connection-string/.

Getting a Database or Collection

Now that we have a client, we can fetch a handle to the collection or database using the following. Keep in mind that these functions return newly allocated structures, and therefore they need to be released when we are done using them.

sudo yum install openssl-devel

Inserting and querying a document

Now that we know how to get a handle to a database and collection, let's insert a document and then query it back!

sudo yum install openssl-devel

BCON simplified document format

Creating BSON documents in the imperative way is time consuming and can be prone to error. BSON C Notation, or

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

4 for short, is a way to create documents that looks much closer to the document format you are trying to create. While the type safety is less than your typical imperative code, it can make for much cleaner C code.

sudo yum install openssl-devel

Counting documents in a collection

To count the number of documents in a collection we need to build a query selector. An empty query selector would count all documents in a collection.

sudo yum install openssl-devel

Threading

The mongo-c-driver is threading unaware for the vast majority of things. This means it is up to you to guarantee thread-safety. However,

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

5 is thread-safe. It is used to fetch a

git clone git://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
./autogen.sh --prefix=/usr --libdir=/usr/lib64
gmake
sudo gmake install

6 in a thread-safe manner. After retrieving a client from the pool, the client structure should be considered owned by the calling thread. When the thread is finished, it should be placed back into the pool.

sudo yum install openssl-devel

Executing a Command

There are helpers to make it easy to execute commands. The helper exists for client, database, and collection structures. Alternatively, you can use the

git clone git://github.com/mongodb/mongo-c-driver.git
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

7 variant if you do not need a cursor back from the result. This is convenient for commands that return a single document.

MongoDB digunakan untuk apa?

3. Cocok Untuk Menampung Data yang Bervariasi Dynamic schema membuat MongoDB cocok untuk menampung data yang bervariasi baik digunakan untuk menyimpan data yang terstruktur ataupun yang tidak terstruktur.

MongoDB menggunakan bahasa apa?

MongoDB sendiri ditulis dengan bahasa C++ dan telah tersedia untuk berbagai jenis bahasa pemrograman. Fitur utama dari mongoDB antara lain: model document-oriented storage.

Kapan harus menggunakan MongoDB?

Dari sisi struktur data, MongoDB cocok digunakan untuk data yang tidak terstruktur.

Mengapa MongoDB disebut basis data non relasional?

MongoDB merupakan sebuah database yang memiliki konsep NoSQL. Istilah ini dapat diartikan secara awam dengan non relasional karena berbeda dengan MySQL yang merupakan RDBMS (relational database management system).
