RHEL Installation

A mirror should be setup firstly before installation. For RHEL, there is only one way to setup mirror currently.

• Local ISO mirror: Download RHEL ISO image, mount ISO image in a local server as the repository, http service for this repository is provided so that a node could access without proxy.

Local ISO Mirror

mkdir ~/iso && cd !/iso

# Download iso file from `<redhat.com>`_
# Here we use rhel-server-7.0-x86_64-dvd.iso for example

# Create mirror folder
mkdir -p /var/mirrors/rhel

# Replace {on-http-dir} with your own
mkdir -p {on-http-dir}/static/http/mirrors

# Mount iso
sudo mount rhel-server-7.0-x86_64-dvd.iso /var/mirrors/rhel

# Replace {on-http-dir} with your own
sudo ln -s /var/mirrors/ubuntu {on-http-dir}/static/http/mirrors/
