Learning Basics of L"'8 Server LAMP is an acronym for a web services solution stack consisting of Linux, the Apache

HTTP Server, the MySQL or MariaDB database engines, and the PHP or Perl, or

Python programming language. All components are free and open-source software, andthe combination is suitable for building dynamic web pages.The combination of the

software included in a LAMP stack may vary, for example the Apache web server can

be replaced by some other web server software. Although the original authors of these

programs did not design them to work as a component of the LAMP stack, the

development philosophy and tool sets are shared and were developed in close

conjunction. The software combination has become popular because it is entirely free

and open-source software, which means that each component can be adapted to the

underlying hardware and customized to meet the specification as exactly as possible,

without overt vendor lock-in. The complete software stack is also free of cost,maximizing the available budget for tailoring the hardware and software. Due to the

nature of free and open-source software and the ubiquity of its components, each

component of the LAMP stack has been tested for performance and security. At the

same time, continuing development and an abundance of experienced developers

permit new features and custom modification for specific applications. The components

of the LAMP stack are present in the software repositories of most Linux distributions,

providing a simple way to install, set up and operate a LAMP stack out of the box. The

website of a small company is typically not subject to high traffic and is not prone to

frequent attacks, and can therefore be administered with minimal resources.

The LAMP bundle can be and often is combined with many other free and open-sourcesoftware packages such as, for example:

• netsniff-ng for security testing and hardening

• Snort, an intrusion detection (IDS) and intrusion prevention system (IPS)

• RRDtool for diagrams

• Nagios, Collectd or Cacti, for monitoring.

Learning Installing LAMP On Ubuntu

In this guide I will show you how to install a LAMP system. LAMP stands for Linux, Apache, MySQL,

PHP. The guide is intended to help those who have very little knowlegde of using Linux.

Install Apache

To start off we will install Apache.

1. Open up the Terminal ( Applications > Accessories > Terminal).

2. Copy/Paste the following line of code into Terminal and then press enter:

sudo apt-get install apache2

3. The Terminal will then ask you for you're password, type it and then press enter.Testing Apache

To make sure everything installed correctly we will now test Apache to ensure it is working properly.

1. Open up any web browser and then enter the following into the web address:

http://localhost/

You should see a folder entitled apache2-default/ . Open it and you will see a message saying "It works!" ,

congrats to you!

Install PHP

In this part we will install PHP 5.

Step 1. Again open up the Terminal ( Applications > Accessories > Terminal).

Step 2. Copy/Paste the following line into Terminal and press enter:

sudo apt-get install php5 libapache2-mod-php5

5e/t of CS @(A 1# (CS$#1


16/29

Step 3. In order for PHP to work and be compatible with Apache we must restart it. Type the following code

in Terminal to do this:

sudo /etc/init.d/apache2 restart

Test PHP

To ensure there are no issues with PHP let's give it a quick test run.

Step 1. In the terminal copy/paste the following line:

sudo gedit /var/www/testphp.php

This will open up a file called phptest.php.

Step 2. Copy/Paste this line into the phptest file:

Step 3. Save and close the file.

Step 4. Now open you're web browser and type the following into the web address:

http://localhost/testphp.php

The page should look like this:

Congrats you have now installed both Apache and PHP!

Install MySQL

To finish this guide up we will install MySQL. (Note - Out of Apache and PHP, MySQL is the most difficult

to set up. I will provide some great resources for anyone having trouble at the end of this guide.)

Step 1. Once again open up the amazing Terminal and then copy/paste this line:

sudo apt-get install mysql-server

Step 2 (optional). In order for other computers on your network to view the server you have created, you

must first edit the "Bind Address". Begin by opening up Terminal to edit the my.cnf file.

gksudo gedit /etc/mysql/my.cnf

Change the linebind-address = 127.0.0.1

And change the 127.0.0.1 to your IP address.

Step 3. This is where things may start to get tricky. Begin by typing the following into Terminal:

mysql -u root

Following that copy/paste this line:

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yourpassword');

(Make sure to change yourpassword to a password of your choice.)

Step 4. We are now going to install a program called phpMyAdmin which is an easy tool to edit your

databases. Copy/paste the following line into Terminal:

sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadminAfter that is installed our next task is to get PHP to work with MySQL. To do this we will need to open a

file entitled php.ini. To open it type the following:

gksudo gedit /etc/php5/apache2/php.ini

Now we are going to have to uncomment the following line by taking out the semicolon (;).

Change this line:

;extension=mysql.so

To look like this:

extension=mysql.so

Now just restart Apache and you are all set!

sudo /etc/init.d/apache2 restart

With This We are all set to start Our LAMP Project

Learning " 5ee/ 5ive in 'S;

MySQL officially, but also called "My Sequel" is (as of March 2014) the world's second most[a]

widely used open-source relational database management system (RDBMS).It is named after co-founder Michael Widenius's daughter, My. The SQL phrase stands for Structured Query Language.[6]The MySQL development project has made its source code available under the terms of the GNUGeneral Public License, as well as under a variety of proprietary agreements. MySQL was ownedand sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by OracleCorporation.

MySQL is a popular choice of database for use in web applications, and is a central component ofthe widely used LAMP open source web application software stack (and other 'AMP' stacks). LAMP

is an acronym for "Linux, Apache, MySQL, Perl /PHP /Python." Free-software-open source projectsthat require a full-featured database management system often use MySQL.

asi*s of PSP We( Programming

PHP is a server-side scripting language designed for web development but also used

as a general-purpose programming language. As of January 2013, PHP was

installed on more than 240 million websites (39% of those sampled) and 2.1 million

web servers.[4] Originally created by Rasmus Lerdorf in 1994,[5] the reference

implementation of PHP (the Zend Engine) is now produced by The PHP Group.[6]

While PHP originally stood for Personal Home Page,[5] it now stands for PHP:

Hypertext Preprocessor, which is a recursive acronym. PHP code can be simply

mixed with HTML code, or it can be used in combination with various templating

engines and web frameworks. PHP code is usually processed by a PHP interpreter,

which is usually implemented as a web server's native module or a Common

Gateway Interface (CGI) executable. After the PHP code is interpreted and

executed, the web server sends resulting output to its client, usually in form of a

part of the generated web page – for example, PHP code can generate a web page's

HTML code, an image, or some other data. PHP has also evolved to include a

command-line interface (CLI) capability and can be used in standalone graphical

applications.PHP is free software released under the PHP License. PHP has been

widely ported and can be deployed on most web servers on almost every operating

system and platform, free of charge

Open a Connection to the MySQL Server

Before we can access data in a database, we must open a connection to the MySQLserver.

In PHP, this is done with the mysqi!connect"# function.

Syntax

Use the PHP mysqli_connect() function to open a new connection to theMySQL serer!

In the following example we store the connection in a variable ($con) for later use in the script:

Close Connection

The connection will be closed automatically when the script ends. To close the connection before, usethe mysqli_close() function:

Here we are using two database fields , Namely username for storing user id’s for logins and

password for storing the passwords.

Step 2:- Create login screen

After that we need to create a login screen which will ultimately autehnticate user via

database !, Let’s create a small page and form named login_home.php

Member Login

Username :

Password :

Step: 3 Authenticating users

Once a user has entered the username and password on the login_home.php , the form pass

the values to login_check.php via POST variables , This method is defined at the form

attribute element on login_home.php.

Note:- While the values are passed via $_POST variables, we will be querying passwords indatabase after encrypting them with md5 function .

< ?php

$db_host="localhost"; // Host name of your database server !, In 90% cases it's localhost

$db_uname=""; // Mysql username of your database

$db_passwd=""; // Mysql password of your database

$db_name="test"; // Database name

$db_table_name="users"; // Name of the table we created earlier

// Connect to server and select databse.

$conn = mysql_connect("$db_host", "$db_uname", "$db_passwd") or die ("cannot connect" .

mysql_error());

$conn_db = mysql_select_db("$db_name" , $conn ) or die("cannot select DB" . mysql_error());

// username and password sent from form

$form_uname = $_POST['myusername'];

$form_passwd = $_POST['mypassword'];

// To protect MySQL injection (more detail about MySQL injection)$form_uname = stripslashes($form_uname);

5e/t of CS @(A $- (CS$#1


28/29

$form_passwd = stripslashes($form_passwd);

$form_uname = mysql_real_escape_string($form_uname);

$form_passwd = mysql_real_escape_string($form_passwd);

$form_passwd = md5($form_passwd); //md5 encryption for querying the password from

database

$sql="SELECT * FROM $db_table_name WHERE username='$form_uname' and

password='$form_passwd'";

$result=mysql_query($sql);

// Mysql_num_row is counting table row

$count=mysql_num_rows($result);

// If result matched $form_uname and $form_passwd, table row must be 1 row

if($count==1){ // Register $form_uname, $form_passwd and redirect to file "login_success.php"

$logged_in = TRUE;

session_register("form_uname");

session_register("logged_in");

header("location:login_success.php");

}

else {

echo "Wrong Username or Password";

}

?>

Please note that this is not the best way to store passwords , A better way for ensuring

security is defined in this Password Hashing tutorial. (Credits John Rockefeller)

This code will create sessions which can use to authenticate users on the particular pages ,

These pages just need to check the session value of logged_in , If logged_in is set for true then

the user is authenticated and else it will be redirected to the login page
