Installing Mongodb in Fedora

Introduction

There are two steps for installing Mongodb in Linux operating system.

1. Creating a directory the mongodb server can write to.
2. Choosing a correct version of mongodb base on your operating system.

For Step #1

The mongodb will use /data/db directory as the default path for the data storing.

We can use the following commands to create the directory and set related permissions:

    $ mkdir -p /data/db

    $ chown -R $USER:$USER /data/db

And instead of using the default path, we can create a directory in our home folder for storing data. I prefer this way because there are no permisson issues under our home folder.

We can use the following commands to create the directory under our home folder:

    $ cd ~

    $ mkdir mongodb   

For Step #2

Go to http://www.mongodb.org to get the correct version base on your system.

I am using a 32bits Fedora system, so I use the following command to get and decompress the tgz file :

    $ wget https://fastdl.mongodb.org/linux/mongodb-linux-i686-3.0.1.tgz

    $ tar -zxf mongodb-linux-i686-3.0.1.tgz

After the above commands have been executed successfully, we can get the bin/mongod command to start the database server. And in order to call the mongod command more conveniently, let's put the path which contains mongod command into PATH:

    $ echo "the path which decompress the tgz file 
to"/mongodb-linux-i686-3.0.1/bin >> /etc/profile (this need root permission)

    $ source /etc/profile

After all these have been done, we can start the database server now:

   $ mongod    //for /data/db

OR:

   $ mongod --dbpath "the directories you created for store the mongodb data"

And we have reached the end of this installation, thanks for reading.
