How to install COMODO certificats
Upon requesting certificats at COMODO you will receive the following 4 files:
- AddTrustExternalCARoot.crt
- COMODORSAAddTrustCA.crt
- COMODORSADomainValidationSecureServerCA.crt
- *YOURDOMAINNAME*.cer
To create just one working CRT file you need to combine all the 4 files into a singel CRT file. On a terminal you need to enter the following command:
cat *yourdomainname*.crt ComodoRSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt >> a_name_you_like.crt \\
Open the just new created a_name_you_like.crt and check if the
—–BEGIN CERTIFICATE—–
—–END CERTIFICATE—–
are on top of eachother not beside. So this would be wrong:
—–BEGIN CERTIFICATE———-END CERTIFICATE—–
Correct this and also check that there are no spaces at the end.
Once you have finished editing the file you should be good to go to user your new created file in NGINX or APACHE.
