Create a new user on EC2 and give sudo privileges

Writing by on Monday, 2 of May , 2016 at 10:00 pm

newhost.compute.internal is the new host you launched
ec2-user is the user created by EC2
newuser is the user you want created and need password-less ssh & sudo privileges
– is newuser’s public key

# Copy newuser’s to the new instance
scp -i ~/.ssh/my.pem ~/.ssh/ ec2-user@newhost.compute.internal:~

# Login to the newhost (and sudo as root)
ssh -i ~/.ssh/my.pem ec2-user@newhost.compute.internal
sudo su –

# add newuser and copy the keys
useradd -c “firstname lastname” newuser
cd /home/newuser
mkdir .ssh
cat /home/ec2-user/ >> .ssh/authorized_keys

# provide right ownership and permissions
chmod 700 .ssh
chmod 600 .ssh/authorized_keys
chown -R newuser:newuser /home/newuser

# give sudo access
vim /etc/sudoers
