Command not found: systemctl on Amazon Linux 2018.03

Question

I am following this Amazon AWS guide to install SSL certificates. I am running Apache on AWS EC2 using the Amazon Linux AMI 2018.03. The first step in the guide is to run:

Answer 1

sudo service nginx status

just use the service command

In earlier versions of RHEL use the service command as explained in the documentation here.

# service service_name start

Therefore, in your case:

# service iptables start

You can replace start with restart, stop, status.

List all services with:

# service --status-all
