If can help someone.Tomcat 8
You don't need the xxxx.crt.pem file. Just run the following command on your original version of the keystore file (if renew certificate) for new certificate just use the same keystore file you've just create to get the csr.
So after you receive your zip file from Goddady type the following command.
keytool -import -alias root -keystore tomcat.keystore -trustcacerts -file gd_bundle-g2-g1.crt
keytool -import -alias tomcat -keystore tomcat.keystore -trustcacerts -file 123456fgscd.crt
sudo initctl restart tomcat
Don't forget to setup Catalina to point to your keystore (server.xml file)
Bingo.
