                Add CA cert to local trust store on CentOS, Debian or Ubuntu
              
          
        
      
        
  
      
    
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

test it with wget https://thewebsite.org
