MONGODB INSTALLATION ON UBUNTU

MONGODB INSTALLATION ON UBUNTU OS

Step 1: The Ubuntu package management tool (i.e. dpkg and apt) ensure package consistency and authenticity by requiring that distributors sign packages with GPG keys.

$sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

Step 2: Create mongodb source list.

$echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Step 3: Reload your Repository.

$sudo apt-get update

Step 4:Install mongodb pakages.

$sudo apt-get install mongodb-10gen

Step 5: Test new mongodb.

Let's try  to Start, Stop and Restart MongoDB 

 You can see in the image above, after installation process is finished, it's start mongoDb automatically.  If not, you should use the command : sudo service mongodb start  to start it up.
We also have the command: sudo service mongodb stop  and sudo service mongodb restart  to stop and start it.

 Testing mogodb on mongo shell 

  - To ensure mongodb works well, try some basic command to save new data and find them on mongo shell.
 - To use mongodb on mongo shell, just type : mongo on terminal.
    + To add new data  into mongodb try : db.test.save ({codingtip : 1})
    + To see all data in database , try : db.test.find() 
with db.test is Test database which is auto created by mongodb in installations

RVM INSTALLATION IN UBUNTU

RVM INSTALLATION IN UBUNTU 13

Step 1:The first step is to install some dependencies for Ruby.

$sudo apt-get update

step 2:

$ sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config libgdbm-dev libffi-dev libreadline-dev

step3: Then, run the installer:
$ curl -L https://get.rvm.io | bash -s stable
step4:Make rvm acessible to your enviroment:
$ echo ‘source ~/.rvm/scripts/rvm’ » ~/.bash_aliases && bash

step 5:To check rvm requirements

$ rvm requirements

step 6: Install Ruby 1.9.3:

$ rvm install 1.9.3
step 7:Make 1.9.3 the default version:
$ rvm use 1.9.3 –default
step 8**:And, finally, rails:
$ gem install rails 

 TO GIVE ALIAS NAME FOR RVM

$rvm alias create [newname] [rvm version]

EX:$rvm alias create latest ruby-2.0.0-p247
 
 

RVM FOR WINDOWS

This is done by using a gem called pik.

Step 1: install a gem by issuing fallowing command in command prompt

>gem install pik

...

Successfully installed pik-0.3.0

1 gem installed

Step 2: after successful installation of gem, you can use the ‘pik_install’ script to install the pik executable. Install pik to a location that’s in your path, but someplace other than your rubybin dir. For instance, the directory C:bin is in my path:

>path

PATH=c:\bin;C:\Program Files\Windows Resource Kits\Tools\;c:\ruby\Ruby-186-p383\bin;

So i run,

>pik_install C:\bin

Thank you for using pik.

Installing to C:\bin

...

pik is installed

Simply type the command pik on command prompt, then the current ruby version is added as default ruby of u r system.

>pik

U can add another ruby version by using fallowing commands: 

.....

$ pik install ruby 1.9.2

** Adding:  192: ruby 1.9.2 (2011-06-30 patchlevel 352) [i386-mingw32]

Now we can check current installed versions by fallowing command:

> pik list

  *187: ruby 1.8.7 (2011-06-30 patchlevel 352) [i386-mingw32]

  192: ruby 1.9.2p290 (2011-07-09) [i386-mingw32]

the * before 187 means that we are using Ruby 1.8.7 at this moment, let’s switch to Ruby 1.9.2

> pik use 192

If you run one last command you will see what happened

> ruby -v

ruby 1.9.2 (2011-06-30 patchlevel 352) [i386-mingw32]
