Ubuntu Server , Install with LAMP 
Sun VM VirtualBox , ver 3.2.8 
Date  9 / 10 / 2010   
Document tools : Ubuntu Server + vi  ( 6 )
************************************************************************

I download LiveCD-Server6 from Ubuntu 

and Install In HD ( Oracle VirtualBox )

set ipconfig by  

 # ifconfig eth0 192.168.1.102  netmask 255.255.255.0  up 

set default gateway by 
 # route add default via 192.168.1.1 

In my machin  use  Oracle VirtualBox 

1 NetworkCard is Bridge Mode , Adapter1 as Bridge Adapter , Cable Connected
2 , Adapther 2 as NAT  , Cable not connected

I start ping gateway by ping  192.168.1.1 
and after success , then ping  www.google.co.th

end ping process by  Ctrl + C  (  must  LEFT Ctrl in VirtualBox  )

******************************
Apache2
******************************
Apache2 is in /etc/Apache2
config not in  /etc/apache2/httpd.conf
But  config in /etc/apache2/apache2.conf 

root directory is in 
/var/www 

You must copy file from  /var/www/default-www/*.html.en  to  /var/www by "cp"
and copy *.gif ,*.png from /var/www/default-ww/*.* to /var/www
then rename *.html.en to *.html   by  command "mv"    

then  open browser on host PC ( ex. Windows XP + Chrome ) 
and   enter url  http://192.168.1.102   
then  you will find  Apache page 

start/stop apache2 by
# /etc/init.d/apache2 start 
# /etc/init.d/apache2 stop 
or you can use "sudo" if you not root
$sudo /etc/init.d/apache2 start 
( must enter password of root again ) 


*********************************

end then  save in  /var/www

http://192.168.1.102/phpinfo.php

***********************************

***********************************
mysql is in /etc/mysql  
with config file my.cfg

Can check mysql by run at prompt 
#mysql  {enter}   to run mysql client 
if mysql server running (by default ) 
it will connect to mysql server database
mysql>

(now mysql is part of Oracle ) 

***********************************
