Change directory to conf/cert of your Apache SSL instance home
Generate key and CSR using the CN as the name of the web-site this apache instance will host. (Check the end of the doc to create csr)
Now you will have to give this CSR to the third party company and purchase the SSL certificate from them.
Steps to follow once we get the signed certificate:
ssl_home_ge_com.crt and replace the MY_SERVER1.key ( which gets created from step 3)
Restart the apachessl after all the changes. To use this certificate on other server2 , copy all the certificates there and rename MY_SERVER1.key to MY_SERVER2.key )
# openssl req -new -nodes -keyout MY_SERVER1.key -out MY_SERVER1csr
