Erstellen einer Root CA fuer Apache 2 Webserver
-----------------------------------------------

OpenSSL installieren:
./config shared
make && make test && make install

Eigene Root CA erstellen:
/usr/local/ssl/bin/openssl genrsa -des3 -out ca.key 1024
/usr/local/ssl/bin/openssl req -new -x509 -days 365 -key ca.key -out ca.crt

Private Server-Key erstellen:
/usr/local/ssl/bin/openssl genrsa -des3 -out server.key 1024

Inhalt anschauen:
/usr/local/ssl/bin/openssl rsa -noout -text -in server.key

Certificate Signing Request (CSR) erstellen
CommonName ist URL:
/usr/local/ssl/bin/openssl req -new -key server.key -out server.csr

In /usr/local/ssl ein Script erstellen (sign.sh): 
#!/bin/sh
##
##  sign.sh -- Sign a SSL Certificate Request (CSR)

#   argument line handling
CSR=$1
if [ $# -ne 1 ]; then
    echo "Usage: sign.sign <whatever>.csr"; exit 1
fi
if [ ! -f $CSR ]; then
    echo "CSR not found: $CSR"; exit 1
fi
case $CSR in
   *.csr ) CERT="`echo $CSR | sed -e 's/\.csr/.crt/'`" ;;
       * ) CERT="$CSR.crt" ;;
esac

#   make sure environment exists
if [ ! -d ca.db.certs ]; then
    mkdir ca.db.certs
fi
if [ ! -f ca.db.serial ]; then
    echo '01' >ca.db.serial
fi
if [ ! -f ca.db.index ]; then
    cp /dev/null ca.db.index
fi

#   create an own SSLeay config
cat >ca.config <<EOT

#  sign the certificate
echo "CA signing: $CSR -> $CERT:"
/usr/local/ssl/bin/openssl ca -config ca.config -out $CERT -infiles $CSR
echo "CA verifying: $CERT <-> CA cert"
/usr/local/ssl/bin/openssl verify -CAfile ca.crt $CERT

#  cleanup after SSLeay
rm -f ca.config
rm -f ca.db.serial.old
rm -f ca.db.index.old

#  die gracefully
exit 0

Danach:
./sign.sh server.csr

Wichtige Dateien: server.key und server.crt
Diese in die Verzeichnisse /usr/local/httpd/conf/ssl.crt und ssl.key
kopieren. Mit /usr/local/httpd/bin/apachectl startssl starten!
