Question: I had followed your guide to install Certbot in CentOS Stream 8. However, the certbot --apache command fails with an error message ‘The requested apache plugin does not appear to be installed‘. – Sathish.
# certbot --apache Saving debug log to /var/log/letsencrypt/letsencrypt.log The requested apache plugin does not appear to be installed
Install Certbot apache plugin in CentOS
This tutorial assumes that you had already installed Certbot in CentOS Stream 8. If you haven’t, then you need to install it first before reading further.
The error message clearly says that Certbot requires an apache plugin to be installed. Though you have Apache and Certbox installed, you need certbot apache plugin to fetch the certificate and install it automatically on the Apache webserver.
List certbot plugins:
# certbot plugins - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - * standalone Description: Spin up a temporary webserver Interfaces: Authenticator, Plugin Entry point: standalone = certbot._internal.plugins.standalone:Authenticator * webroot Description: Place files in webroot directory Interfaces: Authenticator, Plugin Entry point: webroot = certbot._internal.plugins.webroot:Authenticator - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
The above output confirms that the Apache plugin is not installed and you need to install one as shown below.
Install certbot apache plugin
# dnf install python3-certbot-apache :::::::::::::::::::::::::::::::: Installed: python3-augeas-0.5.0-12.el8.noarch python3-certbot-apache-1.22.0-1.el8.noarch Complete!
Check if the plugin is installed properly.
# certbot plugins - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - * apache Description: Apache Web Server plugin Interfaces: Installer, Authenticator, Plugin Entry point: apache = certbot_apache._internal.entrypoint:ENTRYPOINT * standalone Description: Spin up a temporary webserver Interfaces: Authenticator, Plugin Entry point: standalone = certbot._internal.plugins.standalone:Authenticator * webroot Description: Place files in webroot directory Interfaces: Authenticator, Plugin Entry point: webroot = certbot._internal.plugins.webroot:Authenticator - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Now the plugin is installed, you are ready to fetch the certificate and install it on the Apache webserver.
