Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.example.com

I ran this command: sudo certbot certonly --apache -w /var/www/html -d www.example.com -d example.com

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache
Cert not yet due for renewal

You have an existing certificate that has exactly the same domains or certificate name you requested and isn’t close to expiry.
(ref: /etc/letsencrypt/renewal/www.example.com.conf)

What would you like to do?

1: Keep the existing certificate for now
2: Renew & replace the cert (limit ~5 per 7 days)

    Your cert will expire on 2018-12-28. To obtain a new or tweaked

Hi @DefiantPanda

if you use certonly, you have to install the certificate manual. This isn't done, there is a "localhost.localdomain" - certificate.

You have 4 certificates created. So the next try -> limit 5 certificates.

https://transparencyreport.google.com/https/certificates?cert_search_auth=&cert_search_cert=&cert_search=include_expired:false;include_subdomains:false;domain:www.example.com&lu=cert_search

Please share your apache configuration.

Sorry what part of the apache do you want? Just the conf file?

There is an additional ssl-configuration file, there are the definitions.

But: You can create 5 certificates per week with the same domain name set, so you should try one time without “certonly”. Perhaps the installation works - and you don’t need to change your configuration manual.

sudo certbot --apache -w /var/www/html -d www.example.com -d example.com

Unfortunately that didn’t work

Are there errors?

Your copy has only the port 80 - part, not the 443-part.

Check

https://httpd.apache.org/docs/2.4/ssl/ssl_howto.html

LoadModule ssl_module modules/mod_ssl.so

Listen 443
<VirtualHost *:443>
    ServerName www.example.com
    SSLEngine on
    SSLCertificateFile "/path/to/www.example.com.cert"
    SSLCertificateKeyFile "/path/to/www.example.com.key"
</VirtualHost>

in one config file from conf.d/*.conf. Port 443 is running, so there must be a place with "SSLCertificateFile" etc.

The httpd.conf file loads the ssl.conf file

Hi,

Could you please try this command?
apachectl -S (this would print all configuration files in use by Apache) (you might need to replace apachectl to apache2ctl if there’s a not found message)

Thank you

10

Running that command got no response
Thanks

11

Hi,

It should not load with no output…
I could see that your web server is Apache /2.4.34 which should have some meaningful output when executing apachectl -S…

The website example.com serves the correct certificate, could you also please try to locate the virtual host / configuration file for that site?

Thank you

12

In httpd.conf it says

# Supplemental Configuration
#
# Load config files in the "/etc/httpd/conf.d" directory, if any.
IncludeOptional conf.d/*.conf

In vhost.conf it has

<VirtualHost *:80>
    DocumentRoot /var/www/html
    ServerName www.example.com
    ServerAlias example.com
    ServerAdmin sdfsdf883812@blah.com.au
 RewriteEngine on
 RewriteCond %{SERVER_NAME} =example.com [OR]
 RewriteCond %{SERVER_NAME} =www.example.com
 RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
13

There you see the usage of your "localhost" - certificate.

Use

certbot certificates

to find the informations of one of your certificates, replace SSLCertificateFile and SSLCertificateKeyFile, reload your server.

14

Thankyou, that worked.

How do you flag a moderator?

@moderators

Thank you (or you are welcome)

Moderation note: Per @DefiantPanda’s request, I’ve edited everyone’s posts to change their domain name to example.com.
