AWS CentOS 7 AMI => Setup for root login via SSH

centos-ami.md

AWS CentOS 7 AMI Setup for mplz

1. SSH to EC2 then exec sudo visudo then add line centos ALL=(ALL) NOPASSWD:ALL
2. exec sudo su - root
3. exec sudo vi /etc/ssh/sshd_config then edit/uncomment line PermitRootLogin without-password
4. exec sudo cp /home/centos/.ssh/authorized_keys /root/.ssh

Additional steps

After using mplz setup && mplz deploy, and nginx doesn't want to serve your Meteor app, it's because of SELinux blocking the reverse proxy. The fix:

1. sudo cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M meteornginx
2. semodule -i meteornginx.pp

Thanks Kevin!
