Installing an SSL certificate on a VPS server could vary based on the server software you’re using. I’ll show you an example on how to do it on an Apache server:
1. Purchase an SSL certificate: You’ll need to buy an SSL certificate from a trusted certificate authority.
1. Generate a Certificate Signing Request (CSR): This is done on your server. On Linux using OpenSSL, the command is: `openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr`. Follow the prompts to input your information.
1. Activate your SSL certificate: You’ll need to give the CSR to the certificate authority when you buy your certificate. They will use it to create your SSL certificate.
1. Install the SSL certificate: Once the certificate authority sends you the SSL certificate, upload it to your server. If they provide you also with a CA bundle, make sure to upload it as well.
1. Configure your server to use the SSL certificate: For Apache, you’ll need to edit your site’s configuration file (often located at /etc/httpd/sites-available/your-site.conf or /etc/apache2/sites-available/your-site.conf). Add these lines inside the `
1. Restart your server: For Apache, this is usually done with `systemctl restart httpd` or `systemctl restart apache2`.
1. Test your SSL certificate: You can do this by visiting your website at https://yourdomain.com. Your browser should indicate that the site is secure. There are also online tools that can test your SSL certificate for you.
Remember that the steps could slightly differ based on your server software and system specifics. Always refer to the official documentation or contact your hosting provider if you need more help.
