Installing MongoDB on Mac OX X Lion

Today I tried to install mongodb via MacPorts on Mac OS X Lion. I got this error message:

Error: Target org.macports.build returned: shell command failed (see log for details)
Log for mongodb is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_databases_mongodb/mongodb/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

Maybe it is not the best idea to install MongoDB via MacPorts. I just downloaded the compiled binarys from the MongoDB Homepage: http://www.mongodb.org/downloads. Just unzip it and that’s it.

No you have to create a directory.

mkdir /data
cd /data
mkdir db

MongoDB expects that this directory exists and puts all necessary DB files into this directory.

Navigate in the command line to the unpacked directory and execute this command as root to start the MongoDB server:

./bin/mongod

And the server is running 🙂
In another shell you can start the client. The client can run without root rights.

./bin/mongo

Now you can start to work

> db.foo.save( { a : 1 } )
> db.foo.find()

  1. Here is a work around to get mongodb to install in MacPorts:

    sudo port install mongodb configure.cc=/usr/bin/gcc configure.cpp=/usr/bin/cpp configure.cxx=/usr/bin/g++

  2. That is up to you. By default it is running under root. And nobody else should write or execute it. But you can also create a mongo user and execute the mongo service as mongo user.
    Self downloaded and installed software is usually under /opt. For example /opt/mongo.
