In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

You have to use a command to connect to your URL like curl. Just entering the URL in bash does not work.

curl http://6.5.4.2

That should print the HTML in your terminal. If you want to interpret the HTML code you could use lynx which is a text-based web browser for shell.

lynx http://6.5.4.2

This is a working sample of bash script which check the apache status, restart it automatically if down, and alert by telegram bot within unicode emoji.

#!/bin/bash
telegram=(xxxxx, yyyyyy)

if ! pidof apache2 > /dev/null
then
    # web server down, restart the server
    echo "Server down"
    /etc/init.d/apache2 restart > /dev/null
    sleep 10

    #checking if apache restarted or not
    if pidof apache2 > /dev/null
    then
        for i in "${telegram[@]}"
        do
        curl -s -X POST https://api.telegram.org/botxxxxxx:yyyyyyyyyyyyyyyyyyyyyyyyyy/sendMessage -d chat_id="$i" -d text="`echo -e '\U0001F525'` Apache stoped on Molib Stage. Automatically restarted succesfully."
        done
    else
        for i in "${telegram[@]}"
        do
        curl -s -X POST https://api.telegram.org/botxxxxxx:yyyyyyyyyyyyyyyyyyyyyyyyyy/sendMessage -d chat_id="$i" -d text="`echo -e '\U0001F525'` Apache stoped on Molib Stage. Automatically restart failed. Please check manually."
        done
