Extract all of the contents of the ZIP file that was sent to you and copy/move them to your server. The extracted contents will typically be named: your-domain.com.crt and ssl-bundle.crt
Note: In case you did not receive a Bundle from Comodo in the email, you have to download and concatenate the following files in this order:
The first file (your-domain.com.crt) can be obtained from the web panel at ClouDNS. The remaining 3 files must be downloaded from Comodo.
Example command for Linux:
Example command for Windowws:
1. Store the bundle in the appropriate nginx ssl folder
2. Store your private key in the appropriate nginx ssl folder,
3. Make sure your nginx config points to the right cert file and to the private key you generated earlier:
Note: If you are using a multi-domain or wildcard certificate, it is necessary to modify the configuration files for each domain/subdomain included in the certificate. You would need to specify the domain/subdomain you need to secure and refer to the same certificate files in the VirtualHost record the way described above.
4. OCSP Stapling Support:
Although optional, it is highly recommended to enable OCSP Stapling which will improve the SSL handshake speed of your website. NginX has OCSP Stapling functionality enabled since version 1.3.7.
In order to use OCSP Stapling in NginX, you must set the following in your configuration:
Where FILE is the location and filename (path) of the ca certificate bundle.
Note 1: For ssl_stapling_verify and ssl_stapling to work, you must ensure that all necessary intermediates and root certificates are installed.
Note 2: The resolver name may change based on your environment.
5. After making changes to your config file check the file for syntax errors before attempting to use it. The following command will check for errors:
6. Restart your server. Run the following command to do it:
7. To verify if your certificate is installed correctly, use COMODO's SSL Analyzer.
