Install SSL Certificate on Apache for CentOS 8

Checking mod_ssl

First, you need to make sure that mod_ssl is installed in the system. To check this use this command:

rpm -qa | grep mod_ssl

Copy

If you see no output, install mod_ssl:

dnf install mod_ssl

Place the SSL certificate on the server

You need to create a complete chain of your SSL certificate from its public key and the chain of certificate authorities.

cat pub-key.pem ca-chain.pem > full-chain.pem

Now place it in the /etc/pki/tls/certs/ folder.
Place the private key to the /etc/pki/tls/private/ folder and make it inaccessible to other users.

chmod -R 600 /etc/pki/tls/private/

configuration

Create a configuration file for your domain name if you don't have one. Put it in the /etc/httpd/conf.d/ folder and give it a name with the .conf extension. Here and further replace domain-name.com with your own.

vi /etc/httpd/conf.d/domain-name.com.conf

Insert the following configuration there:

<VirtualHost *:443>SSLEngine on# The path to the complete chain of your SSL certificateSSLCertificateFile /etc/pki/tls/certs/full-chain.pem# The path to the private keySSLCertificateKeyFile /etc/pki/tls/private/privkey.pem# The path to the content of your website.<Directory /var/www/domain-name.com>AllowOverride All</Directory># The path to the content of your websiteDocumentRoot /var/www/domain-name.com# Domain name of your websiteServerName domain-name.comServerAlias www.domain-name.com</VirtualHost>

Create the /var/www/domain-name.com directory and put the content of your site there, if you haven't already done so.

Redirect from HTTP to HTTPS

To redirect requests from unprotected port 80 (HTTP) to encrypted port 443 (HTTPS), add the following lines to the /etc/httpd/conf.d/domain-name.com.conf file.

<VirtualHost *:80>ServerName domain-name.comServerAlias www.domain-name.comRedirect "/" "https://domain-name.com/"</VirtualHost>

Save and close the file and restart Apache.

systemctl restart httpd

Now you have a configured SSL certificate on Apache with a working HTTPS protocol on your site.
