Hello,
First, you're going to want to create the subdomain named "secure". Second, go into the user panel, click on advanced tools, then "Install SSL Certificate" (or SSL Menu under power_user).
Once there, you'll see 3 main options:
Use the server's certificate
Create your own self signed certificate / Create A Certificate Request
Paste a pre-generated certificate and key
well.. that's actually 4, but the "Create" are blobbed into one. If you are going to be buying a certificate, you'll need to select "Create a Certificate Request" (Select the left radio box to enable the two "Create" radio boxes).
Fill in all relevant info, and be sure to enter "secure.serverenterprise.net" to the Common Name field.
Click save and you should see the request below. If you are an admin, you'll see both the certificate request AND a key. You *must* backup the key, from this window (copy and paste it somewhere), or you'll lose it. Non-admin users with owned IP don't need to worry about this because they'll keep on using the server's cert/key until they switch to theirs. The admin account actually uses the servers main ones, so the new key cannot overwrite the old one until the new certificate has arrived to go with it, or else the old cert and the new key won't match up and apache will not run. Be very carefull... it may be wise to make a backup of the main cert/key pair before you begin.
So assuming you've copy/pasted your key somewhere and sent out your csr, you'll then get the new certificate sent to you. Using your new certificate and the key you copy/pasted, paste both of them OVERTOP of the old ones in the SSL screen. Be sure to not include anything from before. You should now click the "Paste a pre-generated certificate and key" radio button to select the correct save mode. Click save to upload the new cert/key pair (and pray
)
If you wait a minute or so for apache to restart, you should then be able to access
https://secure.serverenterprise.net with the new certificate. You will still get a popup saying the certificate is not valid, because you havn't installed the ca root certificate. To do this, click "Click Here to paste a CA Root Certificate" at the bottom of the SSL screen. Paste the CA certificate provided by the certificate issuer. This is not your certificate, but one that should be available for download from their website. Check "Use a CA Cert", paste the ca cert, and hit save. Wait another minute, close all your browsers, then reload the page.. you shoud be good to go
