Installing Drush v3 in Centos 6

Here are notes I gathered on steps that successfully installed Drush version 3 in my Centos 6.

Move to home dir
cd ~

Remove current drush (if existent)
rm -rf ~/.drush/

Create drush directory (and hide it)
mkdir ~/.drush/

Move to new dir
cd ~/.drush/

Get Drush v3
curl -C - -O -s http://ftp.drupal.org/files/projects/drush-All-versions-3.0.tar.gz

Extract Drush v3
tar -xf drush*.tar.gz

Bin Drush tar
rm -f drush-All*.tar.gz

Pear install console_table
cd drush/includes
curl -C - -O -s http://download.pear.php.net/package/Console_Table-1.1.3.tgz

Extract Pear
tar -xf Console_Table*.tgz

Copy the file
cp Console_Table-1.1.3/Table.php table.inc

rm -r Console_Table-1.1.3
rm -f Console_Table*.tgz

Make drush command executable
cd ~/.drush/
chmod u+x drush/drush

Alias drush and put in bash profile
echo "alias drush='~/.drush/drush/drush'" >> ~/.bash_profile

'Source' the .bash_profile file so updates are made
source ~/.bash_profile

Make sure that we alias drush just in case source does not work
alias drush='~/.drush/drush/drush'

You should see three OK(s) below if the steps below properly executed.

Update Drush using Drush
~/.drush/drush/drush dl drush

Update drush_make and provision in drush/commands
~/.drush/drush/drush dl drush_make
~/.drush/drush/drush dl provision

Move updated additions to correct directory
mv ~/.drush/provision ~/.drush/drush/commands/
mv ~/.drush/drush_make ~/.drush/drush/commands/

You are done and drush is ready to use.
