Create self signed SSL Certificates. However, If you use your server as a business, it had better buy and use a Formal Certificate from Verisigh and so on.
dlp:~ # cd /etc/ssl/private

dlp:/etc/ssl/private # openssl genrsa -des3 -out server.key 2048

Generating RSA private key, 2048 bit long modulus
...................+++

e is 65537 (0x10001)
Enter pass phrase for server.key:     # set passphrase

Verifying - Enter pass phrase for server.key:     # confirm
# remove passphrase from private key

dlp:/etc/ssl/private # openssl rsa -in server.key -out server.key

Enter pass phrase for server.key:     # input passphrase

writing RSA key
dlp:/etc/ssl/private # openssl req -new -days 3650 -key server.key -out server.csr
