Creating the CA (Certificate Authority)

There is quite a bit of preparation and configuration required to create a CA. Fortunately, once the configuration is correct, the remainder of the process is relatively simple.

Create necessary directories and files

Absent these directories, openssl will emit errors during certain steps throughout the overall process.

$ cd ~

• Open a webpage that uses the CA with Firefox
• Click the lock-icon in the addressbar -> show information -> show certificate
• the certificate viewer will open
• click details and choose the certificate of the certificate-chain, you want to import to CentOS
• click "Export..." and save it as .crt file
• Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
• run update-ca-trust extract
• test it with wget https://example.com

On Manjaro (arch) the location for the certificates is: /usr/share/ca-certificates/trust-source/anchors (low priority) or /etc/ca-certificates/trust-source/anchors/ (high priority) and the command to update is update-ca-trust extract.

Based on https://gist.github.com/GAS85/8dadbcb3c9a7ecbcb6705530c1252831

Requirements

• A self-managed VPS or dedicated server with Ubuntu 20.04 running Apache 2.4.xx.
• A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.

Step 1: Install Apache2

Per default it will be apache2 version 2.4.41 what is enought for http2 support.
