Installation RHEL 7.x

Function to install Python3.4

install_python34() {
    pushd /root 1>/dev/null
    wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz > /dev/null 2>&1
    tar zxvf Python-3.4.3.tgz > /dev/null 2>&1
    pushd /root/Python-3.4.3
    ./configure > /dev/null 2>&1
    make > /dev/null 2>&1
    make install > /dev/null 2>&1
    popd 1>/dev/null
}

Install Python 3.4 using SCL

python install scl-utils -y

Install SCL for python34 by adding a repository

cat <<'EOT' >> /etc/yum.repos.d/python34.repo
[centos-sclo-rh]
name=CentOS-7 - SCLo rh
baseurl=http://mirror.centos.org/centos/7/sclo/$basearch/rh/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo
EOT

Install python34 packages

yum -y install $(echo "
rh-python34
rh-python34-python-tkinter
" | grep -v ^#)

Cleanup python 34 repo file

rm -f /etc/yum.repos.d/python34.repo

To install selectors34 first create a virtualenv for python34

scl enable rh-python34 bash
$MYENV=<path to your desired virtual env> # /home/python3env works well for most cases
virtualenv "$MYENV"
yum install -y python-setuptools
easy_install pip
pip install selectors34

Install Python 3.4 using SCL

python install scl-utils -y

For automation you can use code blocks like this

scl enable rh-python34 - << \EOF
    source $MYENV/bin/activate
    pip install selectors34
    python NSConnect.py -h
EOF

Using with Python3.3

If using python 3.3 the selectors package will cause a problem because it it not readily available. To resolve install the selectors34 package with pip.
