How to Install a SSL Cert for a Sub Domain on Bitnami AWS

This is how yo can install a secure SSL (HTTPS) certificate for your sub domain name which can be used for adding a secure shop on your website. I’m deploying on Amazon Web Services (AWS) using a bitnami AMI image so these instructions will be useful if your using this setup. The service I have chosen to use is provided by Comodo (via namecheap) you can get an SSL certificate for only $9 per year and their support was really good (as you will see from screenshots below).

SSL Setup Instructions

buy cert from here: $9 per year

log into your server and generate a CSR

#create private key
sudo /opt/bitnami/common/bin/openssl genrsa -out /opt/bitnami/apache2/conf/server.key 2048

#create CSR
sudo /opt/bitnami/common/bin/openssl req -new -key /opt/bitnami/apache2/conf/server.key -out /opt/bitnami/apache2/conf/cert.csr

Copy your CSR

#copy out your CSR to send off for a certificate
cat /opt/bitnami/apache2/conf/cert.csr

Go to here and click activate

Hi, I’m getting this error from my SSL cert “server certificate does NOT include an ID which matches the server name”. I think it might be because my server is 52.6.126.xx but this is loaded from the A record How can I solve this?

sudo update-ca-certificates
sudo certificates

So you need to include the ca-bundle.crt from here:
