#### Pulls Nodejs Source, Builds and Installs
#
#    I've run this successfully on an AWS EC2 instance running a RHEL AMI.  It
#    should work fine for installs on recent RHEL descended distros.
#
#    Installation is done by pulling this script from curl, and piping it
#    through bash, with appropriate parameters.  This must be run as root,
#    and local files (e.g. temp files) will be created relative to the
#    current working directory.
#
#    To invoke, see "Script Parameters" below, and note name on right-hand-side
#    of each.  Below is an example of how to invoke the script:
#
#    $ screen                 # In case you are ssh'd, so disconnect won't cause issues
#    $ sudo su -              # Must be run as root
#    $ cd <somewhere>         # Tar files will be relative to current working dir
#
#    # The following line is an example that does the heavy lifting of the install.
#    #     (make sure to get the URL from [RAW])
#
#    $ curl https://gist.github.com/.../raw/...<this> | $VERSION=11.0 $VAR2 bash -s
#    

#### Script Parameters (pass in name on right-hand-side of expression)

NODE_VERSION=${VERSION:-12.0}         # Default 12.0.  Check version you specify exists. 
 

#### Step 1: Test for yum and root

if [ -z `which yum` ] ; then
    echo "yum not found.  Install script assumes RHEL-related distro with yum enabled.  Aborting..." >&2
    exit 1
fi

if [ `whoami` != "root" ] ; then
    echo "user not root.  Install script assumes run as root (try: 'sudo su -' first).  Aborting..." >&2
    exit 2
fi


#### Step 1: Update and install developer tools to compile nodejs

yum -y update
yum -y group install "Development Tools"


#### Step 2: Get node source and unpack into directory

DIRNAME="node.${NODE_VERSION}"
mkdir $DIRNAME
cd $DIRNAME

FILENAME="node-v0.${NODE_VERSION}"

wget http://nodejs.org/dist/v0.${NODE_VERSION}/${FILENAME}.tar.gz
gunzip ${FILENAME}.tar.gz

tar -xvf ${FILENAME}.tar

# untarring creates a top-level dir named $FILENAME.  Descend into it

cd $FILENAME

#### Build from src

./configure
make
make install
