Vorbereitung
mkdir /root/ca chmod 700 /root/ca cd /root/ca mkdir certs chmod 700 certs mkdir private chmod 700 private
Root/CA-Zertifikat erstellen
cd /root/ca openssl genrsa -out private/cakey.pem -des3 2048 openssl req -new -x509 -key private/cakey.pem -out certs/cacert.crt -days 3600
Im Common Name (CN) Feld keine Domäne eingeben, sondern z.B. <MeinName> CA Root.
echo "01" > serial.srl chmod 0660 serial.srl
Server-Zertifikat erstellen (z.B. für Apache, Postfix, IMAP)
cd /root/ca openssl genrsa -out www.pem 2048 openssl req -new -sha1 -out www.csr -key www.pem
Im Common Name (CN) Feld die Domäne eingeben.
openssl x509 -req -days 3659 -in www.csr -CA certs/cacert.crt -CAkey private/cakey.pem -CAserial serial.srl -out www.crt
Server-Zertifikat in Apache einbinden
cd /root/ca cp certs/cacert.crt /etc/apache2/ssl/ chmod 600 /etc/apache2/ssl/cacert.crt cp www.crt /etc/apache2/ssl/ chmod 600 /etc/apache2/ssl/www.crt cp www.pem /etc/apache2/ssl/ chmod 600 /etc/apache2/ssl/www.pem
/etc/apache2/vhosts.d/00_default_ssl_vhost.conf:
SSLCertificateFile /etc/apache2/ssl/www.crt SSLCertificateKeyFile /etc/apache2/ssl/www.pem SSLCertificateChainFile /etc/apache2/ssl/cacert.crt
Server-Zertifikat in Postfix einbinden
cd /root/ca cp certs/cacert.crt /etc/postfix/ chmod 600 /etc/postfix/cacert.crt cp www.crt /etc/postfix/ chmod 600 /etc/postfix/www.crt cp www.pem /etc/postfix/ chmod 600 /etc/postfix/www.pem
/etc/postfix/main.cf:
smtpd_tls_key_file = /etc/postfix/www.pem smtpd_tls_cert_file = /etc/postfix/www.crt smtpd_tls_CAfile = /etc/postfix/cacert.crt
Server-Zertifikat in uw-imap einbinden
cd /root/ca cat www.pem >/etc/ssl/certs/imapd.pem cat www.crt >>/etc/ssl/certs/imapd.pem chmod 600 /etc/ssl/certs/imapd.pem
