Installing, starting, and stopping MongoDB under Mac system

I. Download Nodejs, install, until NODE-V displays the version number, indicating that the installation was successful.

Two. This article mainly explains, installs the package way to install MongoDB, as to other way does not introduce.

after downloading MongoDB, copy the mongodb-3.2.5.tar.gz to the/leleda002 path to extract the MongoDB folder, (in which I changed my name and deleted the version number)

The file you just downloaded is not data, etc, and the log folder. There is only one bin folder.

Iii. establishment of documents.

Then create a new data folder in the root directory, and then build a DB folder, that is, in the USR folder above the data folder, which is used to store the database.

Create a new etc folder to put the file configuration.

data/db--and for storing data files, etc--for storing mongod.conf,log--for storing mongod.logs error logs.

Mongod.conf content is as follows

#mongodb config filedbpath=/users/wangxi/documents/mongodb/data/db/logpath=/users/wangxi/ documents/mongodb/true27017truetrue 

This is primarily used to configure the location of the database and the file location of the error output.

Iv. Modifying the system environment variable path

Add the/users/wangxi/documents/develop/mongodb/bin directory to the path.

(In fact, mongodb/bin this address with a shortcut startup directory, find the method of the directory, in the console into the directory, the implementation of PWD can get the directory)

There are many ways to modify environment variables, as follows:

First Add path:

' export Path=/users/wangxi/documents/develop/mongodb/bin: $PATH '

As follows

The shell terminal can be restarted for the environment variable to take effect after the addition is completed

or enter the command source. Bash_profile.

To see if the environment variable was added successfully:

Echo $PATH

As follows:

environment variable added successfully.

4.5. Add operation permissions for database log files.

The newly established DATA/DB needs to add read and write permissions by checking for read and write permissions, if not

sudo chown-r  user name/data/db

V. Start MongoDB

CMD+T Create a new command window, go to MongoDB's "bin" directory, use the command "./mongod" or "Mongod" to start MongoDB server, the last line after successful startup should be the port number, as follows:

This step is connected to the service of MongoDB

Open the browser, enter localhost:27017, and the "

It looks like you is trying to access MongoDB over HTTP on the native driver port.
"Such a line of text, then can reopen a terminal is likewise.

5.5. New window, enter./mongo or MONGO, try to manipulate the database: This step is to operate the database.

The prompt indicates that the connection is successful and a ' > ' symbol is displayed on the terminal, so you can enter MongoDB's SQL command now.

six. To stop MongoDB be sure to exit correctly, or the next time you connect to the database will be a problem.

Execute in the command window that operates the database

Use Admin;db.shutdownserver ();

　　Note: If the installation succeeds, you will only need to start the MongoDB service later, then the gold Operation database will be OK. This is equivalent to just performing the top 5 and 6 steps.

The first 4 steps above are the installation, 56 is to connect the server, start the database.

In connection with the service execution "./mongod" or "Mongod" will often appear some problems, next will I encounter problems in the bottom to do a collation.

First, start the MAC installation Mongoldb error shutting down with code:100.

This is a directory-specific issue.

Refer to my startup command.

./mongod--dbpath. /data/db/ starts the MongoDB Shell Client (Command + T). /mongo

Second, the above step 4 environment variable configuration steps.

If there is an error in the configuration of the environment variable, it can also be understood that the path is specified incorrectly, and this time you want to modify or delete

The configuration of the environment variable is understood to be that he wrote the variable in a file.

VI ~/. bash_profile

~/~/~/~/. Bash_profiledd  The code you want to delete, place your cursor in the row you want to  delete, double-click Dd:wq~/.bash_ Profile or close restart shell

After you have finished changing the output, you can see if the changes have been made.
