Abstract
LAMP is a shorthand term for a web application platform consisting of Linux, Apache, MySQL and one of Perl or PHP. Together, these open source tools provide a world-class platform for deploying web applications.Running on the Linux operating system, the Apache web server, the MySQL database and the programming languages, PHP or Perl deliver all of the components needed to build secure scalable dynamic websites. LAMP has been touted as "the killer app" of the open source world.
With many LAMP sites running Ebusiness logic and Ecommerce site and requiring 24x7 uptime, ensuring the highest levels of data and application availability is critical. For organizations that have taken advantage of LAMP, these levels of availability are ensured by providing constant monitoring of the end-to-end application stack and immediate recovery of any failed solution components. Some also supports the movement of LAMP components among servers to remove the need for downtime associated with planned system maintenance.
Technologies on the client side:
1. Active X Controls:
Developed by Microsoft these are only fully functional on the Internet Explorer web browser .This eliminates them from being cross platform, and thus eliminates them from being a webmasters number one technology choice for the future. Disabling Active X Controls on the IE web browser is something many people do for security, as the platform has been used by many for unethical and harmful things..
2. Java Applets :
Java Applets are programs that are written in the Java Language. They are self contained and are supported on cross platform web browsers. While not all browsers work with Java Applets, many do. These can be included in web pages in almost the same way images can.
3. Dhtml and Client-Side Scripting :
DHTML, javascript, and vbscript. They all have in common the fact that all the code is transmitted with the original webpage and the web browser translates the code and creates pages that are much more dynamic than static html pages. Vbscript is only supported by Internet Explorer. That again makes for a bad choice for the web designer wanting to create cross platform web pages. With Linux and other operating systems gaining in popularity, it makes little sense to lock yourself into one platform.
APPLYING LAMP
1.Storing our data:
Our data is going to be stored in the MySQL Database. One instance of MySQL can contain many databases. Since our data will be stored in MySQL it will be searchable, extendable, and accessible from many different machines or from the whole World Wide Web.
2.User Interface:
Although MySQL provides a command line client that we can use to enter our data we are going to build a friendlier interface. This will be a browser-based interface and we will use PHP as the glue between the browser and the Database.
3.Programming:
PHP is the glue that takes the input from the browser and adds the data to the MySQL database. For each action add, edit, or delete you would build a PHP script that takes the data from the html form converts it into a SQL query and updates the database.
4.Security:
The standard method is to use the security and authentication features of the apache web server. The tool mod_auth allows for password based authentication.
