在Raspberry Pi上安装MongoDB--bash：mongo：找不到命令

Question

I'm using a tutorial to install MongoDB on the raspberry pi: http://notejs.com/?p=252

I have followed the instructions with complete success up till the line:

Connect to an instance:

mongo

I then get an error like this:

-bash: mongo: command not found

I have followed this tutorial step by step, the only difference is that I downloaded, compiled and installed MongoDB in a folder that isn't the home folder, could this be the problem?

edit: MongoDB is apparently running already when I enter the command: sudo /etc/init.d/mongod start

So it's not the case that it's too much for my PI

Answer 1

The instructions have this section for making the mongod binary part of your path, which is why that is working:

sudo ln -s /opt/mongo/bin/mongod /usr/bin/mongod

But they do not do the same for the mongo shell binary. Hence you just need to do the same thing for the that binary, that is:

sudo ln -s /opt/mongo/bin/mongo /usr/bin/mongo

Alternatively you could add /opt/mongo/bin to your $PATH variable, or just call /opt/mongo/bin/mongo directly.
