| HAProxy expects an SSL certificate to all be in one file which includes the certificate chain, the root certificate, and the private key. HAProxy has the private key in a separate file, so our last step is to combine the files into something HAProxy can read. | |

| ==== Neue Zertifikate bestellen ====<code> | |

| * ''-standalone'' - Create a stand-alone web server to listen for the cert authorization HTTP request | * ''-standalone'' - Create a stand-alone web server to listen for the cert authorization HTTP request |
| * ''-d [domain]'' - The domain we're creating a cert for. You can use multiple ''-d'' flags for multiple domains for a single certificate. The domain(s) must route to the server we're creating a cert for (DNS must be setup for the domain). | * ''-d [domain]'' - The domain we're creating a cert for.

| * ''–non-interactive –agree-tos –email admin@example.com'' - Make this non-interactive by saying as much, agreeing to the TOS, and informing LetsEncrypt of the email to use to send "YOUR CERT IS EXPIRING" notifications. | * ''–non-interactive –agree-tos –email admin@example.com'' - Make this non-interactive by saying as much, agreeing to the TOS, and informing LetsEncrypt of the email to use to send "YOUR CERT IS EXPIRING" notifications. |
| * ''–http-01-port=8888'' - The Magic™. This tells the stand-alone server to listen on port 8888. Note that LetsEncrypt will //still// send the authorization HTTP request over port **80** and haproxy with redirrect requests over port 8888. The flag is ''http-01'' because it expects an ''HTTP'' request, NOT an ''HTTPS'' request. | * ''–http-01-port=8888'' - The Magic™. This tells the stand-alone server to listen on port 8888.
