How to install SSL on NGINX?

Question

Nginx

There are files from Komodo:
AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt mysite.crt
They
also sent me two files:
mysite.ca-bundle
mysite.crt I
glued them in 2 ways
cat mysite.crt ComodoHigh-AssuranceSecureServerCA.crt AddTrustExternalCARoot.crt > mysite_1. crt
and
cat mysite.crt mysite.ca-bundle > mysite-bundle.crt

}

}

Gives an error
nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)
What to do?

Answer 1

Most likely apache or someone else is already listening on port 443.
sudo netstat -luntp|grep 443
will show you the pid and process name of who is occupying the port.
