And where is the problem? Copy and paste the two certificates in two files in one folder and change the path in your vhost from the certs of the actually SSL Files to the new two files you created. Don’t forget to set the rights with chown / chmod.
Hi there,
You can download the Cloudflare CA certificate from here:
The exact installation instructions would depend on whether you are using Nginx or Apache as your web server.
For example, with Nginx what you would need to do is:
.pem
file and the CA certificate, you can combine them into 1 file with this command:Then you can use that
bundle.crt
file which will contain both the SSL certificate and the CA certificate and define it as normal in Nginx.What I personally do is to install a free Let’s Encrypt SSL with
certbot
so thatcertbot
does all of the Nginx server configuration like updating the server blocks and defining the certificates and the rest of the required SSL configuration. And then I manually update the path to the Cloudflare SSL certificates.However, if you prefer to manually do the configuration you could follow these steps, for example:
Upload the bundle certificate that you’ve just created and private key to your server: You should securely upload the
.pem
file (your SSL certificate) and.key
file (your private key) that Cloudflare provided to your server.Place the certificate and key in a secure directory: A common location to place these is under
/etc/ssl/certs/
for the.pem
certificate file and/etc/ssl/private/
for the.key
private key file. Remember to restrict access to these files using proper permissions. Usually, you can do this with these commands:Replace
/path/to/your/certificate.pem
and/path/to/your/private.key
with the actual paths to your certificate and key.Configure Nginx to use the certificate: Now you should edit your Nginx configuration file to use the SSL certificate for the appropriate server block. Open your site’s configuration file with a text editor. It’s typically located at
/etc/nginx/sites-available/yourdomain.com
.Inside the
server
block for your site, you’ll want to include lines like these:Replace
yourdomain.com
with your actual domain, and make sure the paths to thessl_certificate
andssl_certificate_key
match the locations where you placed your.pem
and.key
files.Test the configuration: Run
sudo nginx -t
to test your configuration. If the configuration is correct, you’ll see a message sayingconfiguration file /etc/nginx/nginx.conf test is successful
. If you see any error messages, check your configuration file for any syntax errors and correct them.Reload or restart Nginx: Once your configuration is correct, you should reload or restart Nginx to apply the changes. You can do this with the command
sudo systemctl reload nginx
orsudo systemctl restart nginx
.Hope that this helps!
Best,
Bobby
