I am not able generate csr from aws acm

I have a domain which i bought on Godaddy, and i deployed the website on amazon ec2, now i am trying to add ssl certificate to my domain and i am not able to generate CSR from the amazon AWS ACM which i need to give as input csr in Godaddy site. When i followed the below documentation https://docs.aws.amazon.com/acm-pca/latest/userguide/PcaGetCsr.html, i could not generate the CSR.

Instructions sent by godday https://in.godaddy.com/help/manually-install-an-ssl-certificate-on-my-aws-server-32075 , but i m not using load balancer for my ec2 instance.

Solution

i have used this command to generate a csr inside ec2 server instance

sudo openssl req -new -key /opt/bitnami/apache2/conf/server.key -out /home/bitnami/digitowork/cert.csr
