How to Install LAMP (Linux, Apache, MySQL, PHP) on Ubuntu (8.04 / 8.10)

This is for the newbies in the world of Ubuntu. Use the following steps to install LAMP (Linux, Apache, MySQL and PHP) in Ubuntu.

• Open up the Terminal (Applications > Accessories > Terminal).
• Run the following command to install Apache
  

  $sudo apt-get install apache2

• To test Apache open up any web browser and then enter the following into the web address:
  

  http://localhost/

• Now run the following command in the terminal to install PHP
  

  $sudo apt-get install php5 libapache2-mod-php5

• 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

• In order to test PHP, in the terminal copy/paste the following line:
  

  $sudo gedit /var/www/testphp.php

• Copy/Paste this line into the phptest file: <?php phpinfo(); ?>
• Save and close the file.
• http://localhost/testphp.php
• Once again open up the amazing Terminal and then copy/paste this line:
  

  $sudo apt-get install mysql-server

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

  $mysql -u root -p

• Following that copy/paste this line:
  

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

• 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 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:
  

  $sudo gedit /etc/php5/apache2/php.ini

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

We are ready to start code in PHP using MySQL for database and Apache as HTTP server in Ubuntu!!!

Installing true type fonts in Ubuntu

Even we are using Ubuntu we may sometimes want to or need to use some Microsoft true type fonts. For that we can follow the following steps to install true type fonts in our Ubuntu.

We can install the MS core fonts by installing the msttcorefonts package.
To do this, enable the “Universe” component of the repositories.
Then run the following command in the terminal:

$sudo apt-get install msttcorefonts

This will give us the core fonts, but if there are other TrueType fonts that we want installed, it is as easy as copying the font files to the ~/.fonts/ directory.

After installing new fonts, we will have to log out and log in again to be able to see and use the new fonts. If we want to avoid this, we can regenerate the fonts cache by issuing the following command:

$sudo fc-cache -fv
