Check subscription manager status

Bash
sudo -s # If in Docker not needed
if [ "$(subscription-manager status| grep "Overall Status")" != "Overall Status: Unknown" ]; then
    clear
    echo "Properly Registered"
else
    echo -e "Needs Registered\n\nPlease get with your server team to register this server"
    $SHELL
fi

Register If Not Registered

Bash
sudo -s # If in Docker not needed
if [ "$(subscription-manager status| grep "Overall Status")" != "Overall Status: Unknown" ]; then
    echo "Properly Registered"
else
    echo -e "\033[32mRed Hat Registration - Start\033[0m"
    if [ -z ${1+x} ]; then
        echo -e "\033[01m\e[4mType your username for RedHat.com, followed by [ENTER]:\e[0m\033[0m"
        read rhUser
    else
        #echo "rhUser is set to '$1'"
        declare rhUser=$1
    fi
    if [ -z ${2+x} ]; then
        echo -e "\033[01m\e[4mType your password for RedHat.com, followed by [ENTER]:\e[0m\033[0m"
        read -s rhPass
    else
        #echo "rhPass is set to '$2'"
        declare rhPass=$2
    fi
    echo -e "\033[32mSet Server Hostname - Start\033[0m"
    if [ -z ${3+x} ]; then
        echo -e "\033[01m\e[4mType your desired hostname for the server, followed by [ENTER]:\e[0m\033[0m"
        read hostname
        hostnamectl set-hostname $hostname
    else
        declare hostname=$3
        hostnamectl set-hostname $hostname
    fi
    echo -e "\033[32mSet Server Hostname - Stop\033[0m"
    # Register Red Hat Server - Start
    subscription-manager register --username $rhUser --password $rhPass
    subscription-manager refresh
    history -c
    subscription-manager identity
    # Register Red Hat Server - Stop
    echo -e "\033[32mRed Hat Registration - Stop\033[0m"
fi

If you have restored a previous snapshot or somehow lost the subscription connection, you should unregister and then go through the above process to “re-register”.

Bash
sudo subscription-manager unregister
