MongoDB installation and testing

Today, I looked at the MongoDB version and found that it has changed again. The release speed of this version is really fast enough. So I downloaded a new version for installation. The previous version was installed on Windows, for Linux 86, follow the tutorial on the official website for Linux installation and testing: http://www.mongodb.org/display/docs/quickstart#unix. the installation and testing procedure are as follows:

Check my environment:

[Root @ localhost/] # uname-
Linux localhost 2.6.18-194. el5pae #1 SMP Fri APR 2 15:37:44 EDT 2010 i686 i686 i386 GNU/Linux

[Root @ localhost/] # Cat/etc/RedHat-release
Centos release 5.5 (final)

Add User:

[Root @ localhost ~] # Useradd MongoDB
[Root @ localhost ~] # Passwd MongoDB

Changing password for user MongoDB.
New UNIX password:
Retype new Unix Password:
Passwd: All authentication tokens updated successfully.

Create a nosql storage directory, which is stored in/data/DB by default. Therefore, create a directory in advance and change the directory owner:

By default MongoDB will store data in/Data/DB,
But it won't automatically create that directory. to create it, do:

[Root @ localhost ~] # Mkdir-P/data/DB/

[Root @ localhost/] # chown-r MongoDB/data/DB/

Copy the file to the user directory:

[Root @ localhost ~] # Music mongodb-linux-i686-2.0.0.tgz/home/MongoDB/
[Root @ localhost ~] # Chown MongoDB/home/MongoDB/mongodb-linux-i686-2.0.0.tgz

[Root @ localhost/] # ll/Data
Total 4
Drwxr-XR-x 3MongoDBRoot 4096 10-13 dB

Switch the user and decompress the file:
[Root @ localhost ~] # Su-MongoDB
[MongoDB @ localhost ~] $ Ls
Mongodb-linux-i686-2.0.0.tgz

[MongoDB @ localhost ~] $ LL
Total 37112
Drwxr-XR-x 3 MongoDB 4096 09-12 mongodb-linux-i686-2.0.0
-RW-r -- 1 MongoDB oinstall 37949452 10-12 mongodb-linux-i686-2.0.0.tgz

Start the server process:

[MongoDB @ localhost dB] $Cd ~ /Mongodb-linux-i686-2.0.0/bin/
[MongoDB @ localhost bin] $PWD
/Home/MongoDB/mongodb-linux-i686-2.0.0/bin
[MongoDB @ localhost bin] $./Mongod
./Mongod -- Help for help and startup options

Open another shell terminal and connect to the client to view the server process:

[MongoDB @ localhost ~] $ PS-Ef | grep Mong

Start the client process, insert a record, and view the record:

[MongoDB @ localhost ~] $./Mongodb-linux-i686-2.0.0/bin/Mongo
