Install CA Certificate

Note: If you are installing a Certificate, you need to first install the Intermediate CA Certificate.

Save the Intermediate as /etc/httpd/conf/ssl.crt/intermediate.crt.
Add the following directive to your /etc/httpd/conf/httpd.conf file, within the virtual host tags that define your secure Web server and with the other SSL directives:

SSLCACertificateFile /etc/httpd/conf/ssl.crt/intermediate.crt 

Install the SSL Certificate

Networking4all will email you your certificate. If the certificate is an attachment (Cert.cer), you can use the file. If the certificate is in the body of the email, copy and paste it into a text file (such as OriginalCert.txt) using Vi or Notepad. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file.

Save the certificate into a file and give the name and path to that file to the SSLCertificateFile directive. Remember that you need to add the key file in as well (SSLCertificateKeyFile directive).  

SSLCertificateFile /etc/httpd/conf/ssl.crt/server.crt 
 
SSLCertificateKeyFile /etc/httpd/conf/ssl.key/server.key
