Steps to create ec2 machine 1. AMI is selected, vendor of AMI. More than 50k ami are available . Such as rhel ,centos. Check architecture, 64 or 32 bit of ami Virtualization - para virt or HVM[hardware assisted vm] ami. You should know Software that are installed on ami. Repository to install software. You should know type of storage supported EBS or instance store. 2. Instance types - t2.micro - general purpose. t stands for type of instance. 2 is revision. Micro says hardware capacity. M4.16xlarge. M is memory optimized, 4 is revision and 16xlarge is hardware capacity C2.xlarge . C is compute optimized,2 is revision and rest hardware configuration. 3. Configure instance - where you want your machine to be launched. There could be Multiple vpc, wheather you want to assign public ip to your instance. What sort of hardware i.e 4. adding storage Root disk . For windows 30 gb. 5. AddTag to instance 6. Security group. You cannot create an instance unless you assign Security group to instance. 7.

How resolve this issue

Thank you very much

Avoid root login! Learn sudo. Is this preeentation from the 1970s? Progress has been made.

journalctl, dmesg is old and not inclusive.

little confusing sorry

Do you have full course?

An user not being able to ssh into a server, first I check whether it is an isolated case. If it is, the most likely cause in a prod environment is either he has forgotten his password or he has not bothered to change his password before expiry or he probably doesn't have account on the server itself. If the login is key-based, then I go into permission of the private key, or check if user's public key is present in remote server etc. But that is super rare. :D

It's nice video, anyone can easily understandable. One doubt, If we are entering/pressing return key in middle of installation, there is no impact right in installation?

Please post what type of issues, that you face in real-time while we are doing in these steps productions. More the errors = more you learn

I hope that you like feedback. I don't recommend installing programs like netstat on the fly. How can you do that in a production environment? If you do not have a tool, use a different one that you do have. Otherwise, I really liked this.

Would love to see you again.

Amazing, a pro technical person.

Thanks sir
