Problem With Sun virtualbox in Ubuntu 8.10

Error : No suitable module for running kernel found

Installing linux-headers-`uname -r`

1) Open the terminal (we will be using it through most of my guide) from Applications > Accessories > Terminal

sudo apt-get install linux-headers-`uname -r`

( This packet is not installed by default when kernel install so we have to install this packet manually )

2)

sudo /etc/init.d/vboxdrv setup


Now it is working :)

Installing LAMP on Ubuntu 7.10/8.04/8.10 (Linux,Apache,MySQL,PHP)

Installing Apache on Ubuntu 7.10/8.04/8.10

1) Open the terminal (we will be using it through most of my guide) from Applications > Accessories > Terminal

2) Install apache2 using apt-get by typing the following


sudo apt-get install apache2


a) start/stop apache2 write:

sudo /etc/init.d/apache2 start


sudo /etc/init.d/apache2 stop

If everything is OK you should see an ordinary HTML page when you type: http://localhost in your firefox browser.

Your www folder should be in: /var/www/



Installing PHP on Ubuntu 7.10/8.04/8.10

1) Also in terminal write:

sudo apt-get install php5 libapache2-mod-php5


2) restart apache

sudo /etc/init.d/apache2 restart

This is it for PHP :D Wanna test it ? Just create an ordinary PHP page in /var/www/ and run it.
Example:

sudo gedit /var/www/test.php

and write in it:

Echo "Hello, World!";
?>


Now run it by typing http://localhost/test.php in firefox… You should see your ” Hello World ”



Installing MySQL on Ubuntu 7.10/8.04/8.10


1. Again and again in terminal execute:

sudo apt-get install mysql-server

2. (optional) If you are running a server you should probably bind your address by editing bind-address in /etc/mysql/my.cnf and replacing its value (127.0.0.1) by your IP address
3. set your root password (although mysql should ask you about that when installing)


mysql> SET PASSWORD FOR ‘root’@'localhost’ = PASSWORD(’xxxxxx’);


4. Try running it

mysql -uroot -pxxx

where xxx is your password.
Note: You can install PHPMyAdmin for a graphical user interface of MySQL by executing

sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin


5. restart apache

sudo /etc/init.d/apache2 restart


Problems with PHP installation :

1) I try to run a PHP file it comes up with a dialog box asking me to download a .phtml file.

-> Install lamp-server by help of follwoing command

sudo tasksel install lamp-server

or

SYS->ADMIN->SYNAPTIC->EDIT->MARK PACKAGES BY TASK->LAMP SERVER
