Certbot doesn't understand my Apache httpd vhost

My domain is: www.reppep.com

I ran this command: certbot -d www.reppep.com

It produced this output:

My web server is (include version): Apache httpd-2.4.57-11.el9_4.1.x86_64

The operating system my web server runs on is (include version): Rocky Linux 9.4

My hosting provider, if applicable, is: Linode

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.11.0

Is there a specification for what certbot requires or needs in vhost files to work properly? Should I ask the certbot people instead of here?

This webserver has many valid domain names. Pre-production it was rocky.reppep.com. Now it's www.reppep.com. I had a certbot cert for www.reppep.com, but after a recent update and reboot, it reverted to a rocky cert. I had several vhost files for www & rocky vhosts, but consolidated down to one while trying to fix this issue. Here's the relevant snippet:

The Rocky Linux RPMs I'm using contain their deficient replacement for apachectl.

I am not sure why Certbot fails to find a port 80 VirtualHost for this name.

But, you have duplicate domain name:port for port 443. HTTPS requests to that domain are getting a faulty cert chain that includes a self-signed cert.

Apache starts up even with this kind of overlap but it causes lots of problems.

Would you show the contents of those two config files?

Thank you very much. I didn't notice that. I moved the 80-to-443 redirect into another file, and the rest of www.reppep.com.conf to the end of ssl.conf. I moved the old www.reppep.com.conf file into a subdirectory where it will not load.

It looks like certbot is putting new certs into my port 80 redirect file, but not updating paths in ssl.conf.

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#     Translate the client X.509 into a Basic Authorisation.  This means that
#     the standard Auth/DBMAuth methods can be used for access control.  The
#     user name is the `one line' version of the client's X.509 certificate.
#     Note that no password is obtained from the user. Every entry in the user
#     file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#     This exports two additional environment variables: SSL_CLIENT_CERT and
#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#     server (always existing) and the client (only existing when client
#     authentication is used). This can be used to import the certificates
#     into CGI scripts.
#   o StdEnvVars:
#     This exports the standard SSL/TLS related `SSL_*' environment variables.
#     Per default this exportation is switched off for performance reasons,
#     because the extraction step is an expensive operation and is usually
#     useless for serving static content. So one usually enables the
#     exportation for CGI and SSI requests only.
#   o StrictRequire:
#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#     under a "Satisfy any" situation, i.e. when it applies access is denied
#     and no other module can change it.
#   o OptRenegotiate:
#     This enables optimized SSL connection renegotiation handling when SSL
#     directives are used in per-directory context.

#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#     This forces an unclean shutdown when the connection is closed, i.e. no
#     SSL close notify alert is sent or allowed to be received.  This violates
#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
#     this when you receive I/O errors because of the standard approach where
#     mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#     This forces an accurate shutdown when the connection is closed, i.e. a
#     SSL close notify alert is sent and mod_ssl waits for the close notify
#     alert of the client. This is 100% SSL/TLS standard compliant, but in
#     practice often causes hanging connections with brain-dead browsers. Use
#     this only for browsers where you know that their SSL implementation
#     works correctly. 
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.

Ah. So the conflict is because pre-certbot, I defined a vhost for www.reppep.com on port 80 in www.reppep.com.80.conf, and ssl.conf contained a vhost for www.reppep.com on port 443. certbot copied my port-80 vhost and changed it to a port-443 vhost, which then conflicted with the one in ssl.conf.

ssl.conf has no servername:

So, it defaults to whatever was defined in the main config file.
[which should NOT have been defined as an FQDN that would be served within a vhost]

I'm not sure what your bracketed comment means, but ServerName www.reppep.com is set in several places, including httpd.conf.

[root@rocky conf.d]# grep -i servername ../conf/*
../conf/httpd.conf:# **ServerName** gives the name and port that the server uses to identify itself.
../conf/httpd.conf:#**ServerName** www.example.com:80
../conf/httpd.conf:**ServerName** www.reppep.com
[root@rocky conf.d]# grep -i servername *.conf
ssl.conf:#**ServerName** www.example.com:443
www.reppep.com.80.conf: **ServerName** www.reppep.com
www.reppep.com.80-le-ssl.conf: **ServerName** www.reppep.com

And it should NOT be there [httpd.conf].
Not when you plan on serving that name within a vhost.

I've done it that way for a very long time, but I defer to you as the certbot expert. I commented it out in httpd.conf.

[root@rocky conf.d]# grep -Ri servername /etc/httpd/*/*.conf
/etc/httpd/conf.d/ssl.conf:#ServerName www.example.com:443
/etc/httpd/conf.d/www.reppep.com.80.conf:	ServerName www.reppep.com
/etc/httpd/conf.d/www.reppep.com.80-le-ssl.conf:	ServerName www.reppep.com
/etc/httpd/conf/httpd.conf:# ServerName gives the name and port that the server uses to identify itself.
/etc/httpd/conf/httpd.conf:#ServerName www.example.com:80
/etc/httpd/conf/httpd.conf:#ServerName www.reppep.com

The hostname is rocky, which I'd like to leave but am considering changing. It looks like httpd is picking it up, and I may change it to www.reppep.com to avoid that.

The easiest way is to make sure all of your VirtualHost have a ServerName (and optionally ServerAlias).

Then you are not relying on Apache using the default hostname.

And make sure each VirtualHost is for a unique set of server names and port

Looks like you still have overlap with rocky.reppap.com. If you don't want that Virtualhost in your ssl.conf to process incoming requests just add a ServerName for something like "mydefault.com" or other nonsense.

Thanks. I think that's just the default, and it should never actually be user visible. After a restart my cert is working again, so I'm good for now. I may well be back next time I need to invoke certbot, though...

Thank you both, very much!

You should give it a name.
But not a name that would be served by any vhost [served now, nor in the future].
I suggest something more functionally descriptive - like: rack04server03.reppep.com

Call it what it is - not what it does [or will do].

You could try this anytime. It checks the renew process without disrupting existing production certs or Apache

sudo certbot renew --dry-run
