How would you like to authenticate with the ACME CA?

1: Spin up a temporary webserver (standalone)
2: Place files in webroot directory (webroot)

Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel): 1
Plugins selected: Authenticator standalone, Installer None

http-01 challenge for ediciones.uis.edu.co

Problem binding to port 80: Could not bind to IPv4 or IPv6.

thenk you

22

If you use the standalone authenticator, first you must stop your normal webserver. So do that or use (2).

23

so do that or use (2) result:

Input the webroot for ediciones.uis.edu.co: (Enter ‘c’ to cancel): /opt/rh/httpd24/root/etc/httpd/conf

\n<p”

IMPORTANT NOTES:

24

There may be a wrong redirect or your webroot - input is wrong. So, if /opt/rh/httpd24/root/etc/httpd/conf is your webroot, create two subdirectories

/opt/rh/httpd24/root/etc/httpd/conf/.well-known/acme-challenge/

there a file (file name 1234) and try to load this file via

http://ediciones.uis.edu.co/.well-known/acme-challenge/1234

to see if that works.

Thank you

You need to use the entire command, not just the modified --apache-ctl param:

./certbot-auto --apache --apache-server-root /opt/rh/httpd24/root/etc/httpd --apache-vhost-root /opt/rh/httpd24/root/etc/httpd/conf.d
–apache-logs-root /opt/rh/httpd24/root/var/log/httpd --apache-challenge-location /opt/rh/httpd24/root/etc/httpd --apache-ctl /opt/rh/httpd24/root/usr/sbin/apachectlwrapper

hello,
use the command the result was:

Certbot can obtain and install HTTPS/TLS/SSL certificates. By default,
it will attempt to use a webserver both for obtaining and installing the
certificate.
certbot: error: unrecognized arguments: apache-logs-root /opt/rh/httpd24/root/var/log/httpd

28

The problem is a missing dash in the param apache-logs-root, here the right command:

./certbot-auto --apache --apache-server-root /opt/rh/httpd24/root/etc/httpd --apache-vhost-root /opt/rh/httpd24/root/etc/httpd/conf.d
--apache-logs-root /opt/rh/httpd24/root/var/log/httpd --apache-challenge-location /opt/rh/httpd24/root/etc/httpd --apache-ctl /opt/rh/httpd24/root/usr/sbin/apachectlwrapper
29

Use the command the result was:

Are you sure you are using the last command I posted above? Because seems like it is using /opt/rh/httpd24/root/usr/sbin/apachectl instead of /opt/rh/httpd24/root/usr/sbin/apachectlwrapper

31

What's the content of 00-base.conf line 40?

Please deactivate your http2 - directive.

32

@JuergenAuer, seems there is a bug in the apache version used by @jadel so the command apachectl doesn’t work and it needs to be executed using scl but there is nothing wrong with the conf (apparently).

I am use the last comand, result:

There you see the line you should deactivate.

Muchas gracias a todos, con su ayuda he instalado certbot en httpd24

Fin del caso.

Happy to read that, https://ediciones.uis.edu.co/ has now a Letsencrypt certificate created today. :wink:

What was the solution?

38

Primero:

echo -e '#!/bin/bash\nscl enable httpd24 -- /opt/rh/httpd24/root/usr/sbin/apachectl $@' > /opt/rh/httpd24/root/usr/sbin/apachectlwrapper

Segundo:

chmod 750 /opt/rh/httpd24/root/usr/sbin/apachectlwrapper

Y después:

./certbot-auto --apache --apache-server-root /opt/rh/httpd24/root/etc/httpd --apache-vhost-root /opt/rh/httpd24/root/etc/httpd/conf.d
--apache-logs-root /opt/rh/httpd24/root/var/log/httpd --apache-challenge-location /opt/rh/httpd24/root/etc/httpd --apache-ctl /opt/rh/httpd24/root/usr/sbin/apachectlwrapper
