Installation of MySql Database Server in Ubuntu 12.04

This are the steps in installing Mysql in Ubuntu 12.04

  1. Open a terminal and enter this command:
    $ sudo apt-get update && sudo apt-get upgrade
  2. Accept the updates and install mysql using this command:
    $ sudo apt-get install mysql-server mysql-client
  3. After the installation process provide a password for root user.
  4. Secure the installation by using this command:
    $ sudo mysql_secure_installation
    This will allow you to set the limitation on how you can access mysql
  5. Here is a sample log details:
    Enter current password for root (enter for none):
    OK, successfully used password, moving on…

    Setting the root password ensures that nobody can log into the MySQL
    root user without the proper authorisation.

    You already have a root password set, so you can safely answer ‘n’.

    Change the root password? [Y/n] n
    … skipping.

    By default, a MySQL installation has an anonymous user, allowing anyone
    to log into MySQL without having to have a user account created for
    them. This is intended only for testing, and to make the installation
    go a bit smoother. You should remove them before moving into a
    production environment.

    Remove anonymous users? [Y/n] y
    … Success!

    Normally, root should only be allowed to connect from ‘localhost’. This
    ensures that someone cannot guess at the root password from the network.

    Disallow root login remotely? [Y/n] n
    … skipping.

    By default, MySQL comes with a database named ‘test’ that anyone can
    access. This is also intended only for testing, and should be removed
    before moving into a production environment.

    Remove test database and access to it? [Y/n] n
    … skipping.

    Reloading the privilege tables will ensure that all changes made so far
    will take effect immediately.

    Reload privilege tables now? [Y/n] y
    … Success!

    Cleaning up…

    All done! If you’ve completed all of the above steps, your MySQL
    installation should now be secure.

    Thanks for using MySQL

  6. We have successfully install our MySQL Database Server.
  7. We will install MySql Navigator so that we can easily access our MySQL Database Server, type this command:
    $ sudo apt-get install mysql-navigator

After the installation we can now easily access our server.

Liferay and Spring-Portlets

I have developed portlets for Liferay portal in my previous work. And I will be working again with Liferay in my upcoming project so i decided to create a tutorial on how to setup Liferay IDE and Liferay runtime environment and also create portlets using spring-portlets.

For those who don’t know what is Liferay, Liferay is an opensource enterprise portal that is used to power intranet and extranet. It is sometimes describe as CMS (content management system), but it is not just a CMS you can setup features in Liferay like Blogs, News and add portlets(there are already made portlets that you can include in your Liferay Portal or you can develop your own portlet.)

In creating our portlet we will be using Spring-portlet framework.

The introduction ends here. We will now setup our Liferay Portal. 🙂
