how to Installation – Configuration Apache PHP5 and MySQL on Ubuntu linux

How do I install and configure PHP5 and MySQL for the Apache 2 web server under Ubuntu Linux operating systems?

php5 is server-side, open source HTML-embedded scripting language. MySQL is database
server for many web-based applications. This FAQ assumes you have installed and configured Apache 2 Web Server.

Install MySQL Server

 

Type the following command to install MySQL server, client and documentation:
sudo apt-get install mysql-server mysql-common mysql-client  mysql-doc-5.0
Edit /etc/mysql/my.cnf, enter:
sudo vi /etc/mysql/my.cnf
Review MySQL settings (the defaults are fine for small usage). To start / stop / restart mysql use the following commands:
sudo /etc/init.d/mysql start
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql restart

Set MySQL root User Password

By default there is no root password for MySQL. Type the following command to set root password:
mysqladmin -u root password 'My-Secret-Password'

Create a Sample Database and User For Testing Purpose

First connect to server, enter:
mysql -u root -p
Sample Outputs:
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 277
Server version: 5.0.67-0ubuntu6 (Ubuntu)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> 
Create a database called nixcraft, type the following at mysql> prompt:
mysql> CREATE DATABASE nixcraft;
Create a user called vivek with password t0mj3rR, enter:
mysql> GRANT ALL ON nixcraft.* TO vivek@localhost IDENTIFIED BY 't0mj3rR';
To quit just type \q and hit [Enter] key.

Install PHP 5

Type the following command to install php5, gd (graphics), MySQL and PostgreSQL database support:
sudo apt-get install php5 libapache2-mod-php5 php5-cgi php5-cli php5-common
 php5-curl php5-gd php5-mysql php5-pgsql
/etc/php5/apache2/php.ini is default php5 configuration file. By default php5 is enabled by installer. You can also run the following command to turn on php5 support
sudo a2enmod php5
Sample Outputs:
Enabling module php5.
Run '/etc/init.d/apache2 restart' to activate new configuration!
Restart the Web server:
sudo /etc/init.d/apache2 restart

Test Your PHP5 and MySQL Configuration

Create a sample program called /var/www/test.php and type the following code:
$link = mysql_connect("localhost", "root", "123456");
   mysql_select_db("mysql");
 
   $query = "show databases";
   $result = mysql_query($query);
   print "<h1>MySQL DB Test executed from ". $_SERVER['SCRIPT_NAME']. "</h1>\n";
   print "Script name: ". $_SERVER['SCRIPT_FILENAME'] ."<hr>\n";
   while ($line = mysql_fetch_array($result))
   {
      print "$line[0]<br>\n";
   }
   mysql_close($link);
   echo "<hr/>Script executed on " . date("d/m/Y");
?>

how to Installing LAMP (Linux, Apache, MySQL and PHP) On Linux Mint

Through this tutorial, you'll learn how to Install Apache, MySQL and PHP.
If you're a webpage designer or developer and use PHP, mySQL and Apache, you'll be needing these applications to be installed. When I istalled Mint, I was looking for a way to install LAMP and found a tutorial on a website by somebody named "Cargoship". That tutorial was for ubuntu. But I installed it on my Linux mint, and it is working.

 

 
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.
 
We will not cover how to install Linux the L of LAMP, because Linux Mint is already installed in your computer.
 

Install Apache

To start off we will install Apache.
1. Open up the Terminal (Applications > Accessories > Terminal).
2. Copy/Paste or type 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! or something like that!
 

Install PHP

In this part we will install PHP 5.
Step 1. Again open up the Terminal (Applications > Accessories > Terminal).
Step 2. Copy/Paste or type the following line into Terminal and press enter:
sudo apt-get install php5 libapache2-mod-php5
Step 3. In order for PHP to work and be compatible with Apache we must restart Apache. 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 or type the following line:
sudo gedit /var/www/testphp.php
This will open up a file called testphp.php.
 
Step 2. Copy/Paste this line into the phptest file:
 
<?php phpinfo(); ?>
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
 
(It will show you the page that has all information about your php. If you have prior experience of installing php in some other OS, you must have seen this page.)
Congrats you have now installed both Apache and PHP!
 

Install MySQL

To finish this guide up we will install MySQL.
Step 1. Once again open up the amazing Terminal and then copy/paste or type 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 line
bind-address = 127.0.0.1
And change the 127.0.0.1 to your IP address.
(In Linux Mint 11, terminal itself asked to the set password, But if it doesn't follow the step 3.)
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 or type 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 or type the following line into Terminal:
sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin
After 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
 

If you get a 404 error upon visiting http://localhost/phpmyadmin: You will need to configure apache2.conf to work with Phpmyadmin.
sudo gedit /etc/apache2/apache2.conf
Include the following line at the bottom of the file, save and quit.
Include /etc/phpmyadmin/apache.conf

Then just restart Apache
sudo /etc/init.d/apache2 restart
 
 

 


Now make wonderful website and have fun!wink
Terminal scares the newbies, but here, you'll see how magical terminal or comand promt (whatever you call it) is.
And as Linux is very secure OS, it'll ask you the password again and again, on every administrative command. You'll have to type in your password many times, whenever terminal asks for it.
