I recently got a linux server running on a cloud and migrated few of my sites including this site. However, I forgot that the main page of this site requires DB package to be installed which can be installed through PEAR, and to cut the story short I end up installing PEAR just to get the DB package installed. Below is how to install PEAR on Linux specifically on Ubuntu 12.04.
wget http://pear.php.net/go-pear.phar sudo php -q go-pear.phar
Below is a suggested file layout for your new PEAR installation. To change individual locations, type the number in front of the directory. Type 'all' to change all of them or simply press Enter to accept these locations. 1. Installation base ($prefix) : /usr 2. Temporary directory for processing : /tmp/pear/install 3. Temporary directory for downloads : /tmp/pear/install 4. Binaries directory : /usr/bin 5. PHP code directory ($php_dir) : /usr/share/pear 6. Documentation directory : /usr/docs 7. Data directory : /usr/data 8. User-modifiable configuration files directory : /usr/cfg 9. Public Web Files directory : /usr/www 10. Tests directory : /usr/tests 11. Name of configuration file : /etc/pear.conf 1-11, 'all' or Enter to continue: Beginning install... Configuration written to /etc/pear.conf... Initialized registry...

Run it without parameters to see the available actions, try 'pear list' to see what packages are installed, or 'pear help' for help. For more information about PEAR, see: http://pear.php.net/faq.php http://pear.php.net/manual/ Thanks for using go-pear!
Once you have successfully installed PEAR, you can start installing PEAR packages by invoking pear.
pear install DB
That’s about it, let me know should you encounter installation issues with PEAR.
