Login into EC2 Instance as root

Question

I am using putty to login to my ec2 instance. When i typed root it asked me to login as ec2-user.

Authenticating with public key "imported-openssh-key" Please login as the ec2-user user rather than root user.

when i did login as ec2-user and tried to run commands like

yum install httpd

it says

Loaded plugins: fastestmirror, priorities, security, update-motd You need to be root to perform this command.

I am running the instance for the first time. I tried searching through the amazon aws help section and google. Not able to find the solution.

Answer 1

To switch to a root shell, run the command:

su

If you want to execute a command as root without switching to a root shell, you can use:

sudo yum install httpd

Answer 2

当我在yum install命令前面添加sudo时，它对我yum install ：

sudo yum install docker

Answer 3

如果有人想切换回 root 用户，只需在您的用户终端中输入命令“exit”。

Answer 4

• Write the below command before writing any command

sudo su

After that you will be the root user. Enjoy:)
