    Install Mikrotik CHR on Digital Ocean Ubuntu 18.04 LTS Droplet. Tested 11/2021

    1. Turn Off Droplet after creation and go to Recovery and set it to Boot from Recovery ISO.

    2. Trun on Droplet and open Console

    3. Press 6 and go to shell

    4. Paste below code to install CHR on HDD

    wget -O- https://download.mikrotik.com/routeros/6.48.1/chr-6.48.1.img.zip | funzip | dd of=/dev/vda bs=1M

    5. So get IP address and Gateway by using below codes:

    7. Turn off droplet and set the Recovery to normal and using Had disk.

    8. Open Console again and login to Mikrotik by using credintioal of
    user: admin
    password: [EMPTY]

    9. So type below codes to set the IP on Mikrotik console:
    * Remember you have to replace Address and Gateway that you find it in step 5.

    /ip address add address=[ADDRESS] interface=ether1
    /ip route add gateway=[GATEWAY]
    /ip dns set servers=8.8.8.8,8.8.4.4

    10. Your Mikrotik CHR is now ready. try ping to google.com using:

    /ping google.com

    if it's OK, hit CTRL+C.
    11. So, you can access your mikrotik by using winbox or a browser by opening the address.
