How to Install an SSL Certificate on the RedHat Linux Server

RedHat Linux Server is a Linux-based server platform that is fast, scalable and secure for the business environment. In this article, we will show you a step-by-step guide for installing the SSL certificate on RedHat Linux Server.

Download Certificate received from CA/ Certificate Provider:

  • When you complete the process of obtaining the SSL certificate, you will receive a zip file by email. It should have a Zip extension that contains all your certificate files. You must download it and extract that Zip file to a specific location such as a desktop/server.
  • Now, copy the extracted files in notepad/Notepad++. While copying files, do not forget to include ‘Begin Certificate’ and ‘End Certificate’.
The Text File Should Look Like:


[encoded data]

  • When you complete it, you should save it as mydomain.crt. Now, save .crt file to your server directory.
For Example – /mydomain/httpd/conf/ssl.crt/
  • While the path for Private key, CA-Bundle, and main certificate path would be as follows.
/mydomain/httpd/conf/ssl.crt/ - You need to store all the certificates here.
/mydomain/httpd/conf/ssl.key/ - You should store the server’s private keys here.
/mydomain/httpd/conf/ca-bundle/ - You should store all the bundle files by certificate authority here.

Install CA certificate in Virtual Host:

  • You should now open Virtual Host and .config file with notepad/text editor.
  • After that, in SSL Section in .config file add 3 below files:
SSLCertificateFile / mydomain/httpd/conf/ssl.crt/server.crt
SSLCertificateKeyFile /mydomain/httpd/conf/ssl.key/server.key
SSLCACertificateFile / mydomain /httpd/conf/ssl.crt/ca-chain-pem.txt
  • Finally, save httpd.config file and restart your server.

Run SSL Checker:

You should run an SSL checker tool to check whether the certificate is installed properly or not. SSL Checker will provide you algorithm, server, keysize, certificate issuer, serial number etc.
