Step one: Loading the Site Certificate

You will receive an email from Positive SSL with the certificate in the email (yourdomainname.crt). When viewed in a text editor, your certificate will look something like:


Copy your Certificate into the directory that you will be using to hold your certificates. In this example we will use /etc/ssl/crt/. Both the public and private key files will already be in this directory. The private key used in the example will be labeled private key, and the public key will be yourdomainname.crt. We recommend that you make the directory that contains the private key file only readable by root.

Login to the Administrator console and select the site that the certificate was requested for.

Select Services, then Actions next to Apache Web Server and then SSL Settings. There should already be a 'Self Signed' certificate saved.

SSL Setting in Apache Server

Select 'Import' and copy the text from the yourdomainname.crt file into the box

Save SSL Certificate

Select 'Save', the status should now change to successful.

SSL Status in Apache Server

Logout -- do not select delete as this will delete the installed certificate.

Step two:Install the Positive SSL Intermediate Certificate

1. You will need to install the Intermediate certificates in order for browsers to trust your certificate. As well as your SSL, three other certificates are also attached to the email from Positive SSL. You will need to install the AddTrustUTNServerCA and the PositiveSSLCA intermediate certificates. This is done by combining these file in a single PositiveSSLBundle file (file which you can download from our support section also sent to you in the zip file as XXXXXX-ca-bundle). In the Virtual Host settings for your site, in the virtual site file, you will need to add the following SSL directives. This may be achieved by:

  1. Copy the AddTrustUTNServerCA and the PositiveSSLCA intermediate files into a new file called ca.txt (with the AddTrustUTNServerCA on top and the PositiveSSLCA underneath) and place this in the same directory as the certificate.
  2. Add the following line to the virtual host file under the virtual host domain for your site (assuming /etc/ssl/crt is the directory mentioned in 1.), if the line already exists amend it to read the following:

SSLCACertificateFile /etc/ssl/crt/ca.txt

If you are using a different location and certificate file names, you will need to change the path and filename to reflect this.

The SSL section of the updated virtual host file should now read similar to this example (depending on your naming and directories used):

  1. SSLCertificateFile /etc/ssl/crt/yourdomainname.crt
  2. SSLCertificateKeyFile /etc/ssl/crt/private.key
  3. SSLCACertificateFile /etc/ssl/crt/ca.txt
  4. Save your virtual host file and restart Apache.

You are now set to start using your Positive SSL certificate with your Apache Ensim configuration.
