Mac under Install Start MongoDB

I recently started the Mac, in the use of Mac has a lot of unfamiliar places, slowly groping, recorded, for follow-up and reference:

To install MongoDB mode under Mac

First, with browser or third-party tools to download
Current version of:http://downloads.mongodb.org/osx/mongodb-osx-x86_64-2.4.6.tgz

The second, through the homebrew installation mongodb,terminal run the following instructions can be

Here, I only speak through homebrew to install.

Install MongoDB under Mac, via homebrew

1. Installing MongoDB via Homebrew

    $ brew Update     $ brew Install MongoDB

If you don't have a homebrew, you should put one first, and the programmer must.

2. MongoDB data default exists/data/db, so need to create this folder, and set permissions

Take the first step, where we can perform the installation

sudo mongod

After executing the sudo mongod command, a bunch of error messages are returned, as follows:

So a bunch of wrong messages, the point is these words

Error:dbpath (/data/db) does not exist. Create this directory or give existing directory In–dbpath. See Http://dochub.mongodb.org/core/startingandstoppingmongo

The error message means dbpath (/data/db) No, you need to create /data/db this directory or use --dbpath a parameter entry to specify a directory that already exists.

DBPath (/data/db) This directory is the place to store MongoDB data files

Since it doesn't exist /data/db , let's create this directory.

First return to the disk root in the terminal input cd / command

then enter the command

Mkdir-p/data/db    Create/data/db

Re-enter the sudo mongod command to start the MongoDB service, and the service exits again to return a bunch of information as follows:

The reason for the error is that these sentences log

Create/open lock file:/data/db/mongod.lock errno:13 Permission denied is a mongod     instance already running?, Terminat Ing

Meaning is not to create and open /data/db/mongod.lock this file, because Permission denied (Permission denied), it appears that the current user mongod to execute this command, the /data/db directory does not have permission to operate, OK, know the reason is good to do, to /data/db add permissions.

Enter the following command at the terminal:

sudo chown-r  The user name that is currently logged on/data

If you are not sure you can run $ whoami first

Again in the terminal input sudo mongod start MongoDB service

3. Add Mongodb/bin to $path, lest we enter sudo monogd each time and become direct MONOGD

    $ touch. Base_profile    $ vim. Base_profile

Restart terminal after adding the following address

Export Mongo_path=/usr/local/mongodb  export path= $PATH: $MONGO _path/bin  

4. Start MongoDB

$ mongod

5. Query Database

Run in another terminal window

$ mongod

You can then start various database directives, such as

    $show DBS    Displays databases that already exist    $use somedbname    Create (use) a database

6. Exit

$exit
