Install SSL Certificates on Linux Server

To install the SSL Certificate on Linux servers, need to make sure we have completed with the following steps.

  1. We need to buy/renew SSL Certificate
  2. We need to Generate CSR with SHA-2 algorithm
  3. Need to save the CSR & Private key file on your server
  4. Need to apply for SSL Certificate
  5. Need to Submit SSL Certificate
  6. Need to download and extract all certificate files and install intermediate CA certificate

Step 1: Download & Extract Certificate files

Once we get ssl certificate, need upload your ssl certificates in to your Linux server.

Step 2: Installation of Intermediate CA certificate

  • Open the intermediate certificate file by using any text editor and copy all the encrypted data into a new file and save the new file with the crt name(extension of this file must be .crt).
  • Need to copy this file in to apache httpd path – /etc/httpd/conf/ssl.crt/intermediatecert.crt
  • Need to open CNF file using with any text editor via etc/httpd/conf/httpd.conf location.
  • By using virtual host tag, need to add following configuration in the cnf file
SSLCACertificateFile /etc/httpd/conf/ssl.crt/intermediate.crt

Step 3: Install SSL Certificate File

  • We need to open the ssl certificate file with text editor and save it with new name as like server-cert.crt
  • Need to save ssl certificate file in the following location /etc/httpd/conf/ssl.crt/server-cert.crt
  • Need to follow the same way add in your server.key file at /etc/httpd/conf/ssl.key/server.key

And in httpd.cnf file, need to use virtual host tag with directives configuration

SLCertificateFile /etc/httpd/conf/ssl.crt/server.crt
SSLCertificateKeyFile /etc/httpd/conf/ssl.key/server.key
SSLCACertificateFile /etc/httpd/conf/ssl.crt/intermediate.crt

  • Save your httpd.cnf file & restart the web server.
