Install MongoDB on Linux
1. Download the binary and extract it
cd /opt/
sudo wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.0.6.tgz
sudo tar -xzf mongodb-linux-x86_64-2.0.6.tgz
2. Create a softlink to you're extracted mongodb content/folder
sudo ln -s mongodb-linux-x86_64-2.0.6 mongodb
3. Create soflinks for mongo binaries
cd /usr/bin
sudo ln -s /opt/mongodb/bin/mongod
sudo ln -s /opt/mongodb/bin/mongo
4. Generally MongoDB save you're database stuff into the directory. So we should create the directory if it doesn't exists
sudo mkdir /data
sudo mkdir /data/db
5. Start the MongoDB Server
sudo mongod
I hope these steps helpful to install MongoDB without any issues, If you have any issues let me know.
