 You install the chain certificate in three main steps:
 Save the certificate in the directory identified by the
SSLCACertificatePath entry (in "httpd.conf")
Calculate a hash value for the certificate
Create a symbolic link to the certificate file using the hash value as
the link name.
The steps below assume that SSLCACertificatePath is set to <SSLTOP>/CA
in your "httpd.conf" file. If you are using a different path, please
substitute the correct path where appropriate.
 Ensure that you have saved the chain certificate as a text file. See
How to save your certificates in a file for instructions.
Copy the certificate file to the directory <SSLTOP>/CA/. For example:
 cp /tmp/mychaincert.txt <SSLTOP>/CA/mychaincert.pem
  Change to the CA directory (<SSLTOP>/CA/).
Calculate a hash of the certificate file using the x509 utility that
comes with SSLeay. For example:
 ssleay x509 -hash -noout < mychaincert.pem
 The hash value is displayed (for example, "4b24ae9b").
Create a symbolic link to the certificate file (for example,
mychaincert.pem). The name of the link is the hash value you just
calculated with a ".0" extension as shown below.
 ln -s mychaincert.pem <hash_value>.0
 특히 이해가 안되는 부분이 <SSLTOP>/CA인데 이 CA라는 디렉토리를 찾을 수
가 없더군요.
이 디렉토리를 만들기 위해 무엇이 필요한지 따로 설정을 해야 할 부분이 있
는지 아시는 분은 답해주십시요.
