    In the error, you can find one of the solutions to the error:

    ImportError: 'pyOpenSSL' module missing required functionality. Try upgrading to v0.14 or newer.

    Try upgrade the package with the following command:

    $ pip install "pyOpenSSL>=0.14"

    Certbot is packaged in an extra repository called Extra Packages for Enterprise Linux (EPEL). To enable this repository on CentOS 7, run the following yum command:

    $ sudo yum --enablerepo=extras install epel-release

    Afterward, the certbot package can be installed with yum:

    $ sudo yum install certbot

    You may confirm your install was successful by calling the certbot command:

    $ certbot --version

    Output:

    certbot 0.31.0

    Install it from EPEL.

    yum install epel-release
yum install certbot

    pip may sometimes not work because of python versions.
    Consider certbot a system-wise software.

    When I want to install via pip, I’d always use virtualenv.
