Hello,

# Clone rbenv into ~/.rbenv
git clone git@github.com:sstephenson/rbenv.git ~/.rbenv

# Add rbenv to your PATH
# NOTE: rbenv is *NOT* compatible with rvm, so you'll need to 
# remove rvm from your profile if it's present. (This is because
# rvm overrides the `gem` command.)
echo 'export PATH="$HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH"' >> ~/.bash_profile
exec $SHELL

XAMPP mysql port in use/can't start mysql .
 This is caused by installing MYSQL  using the terminal and then install XAMPP .
the mysql for xampp wont get the port 3306 , since is currently owned by the one installed 1st.

so, You should uninstall both XAMPP and the mysql server installed via terminal. 

$:  sudo apt-get remove mysql *
$: sudo rm -rf /opt/lampp

TroiSilver

run the command :
$ cd  /opt/lampp/

troi@ubuntu:/opt/lampp$ sudo ./manager-linux-x64.run*

this will run the actual gui for xampp
thanks....
