Let’s take a look at how our Support Team is ready to help customers install SSL certificate

Linode Install SSL Certificate

Linode is not a certificate authority and does not provide SSL certificates. Hence, we have to rely on a 3rd party SSL certificate provider for our Linode server. Let’s Encrypt is a popular and free certificate provider in these scenarios. Our Support Techs are here to take you through the process of installing SSL certificates on different configurations:

• Apache on CentOS
• Apache on Debian & Ubuntu

Install SSL Certificate: Apache on CentOS

1. First, ensure that Apache mod_ssl module is installed on the system. If not, we can do so with the command:

   yum install mod_ssl
2. Then, we will edit the /etc/httpd/conf.d/ssl.conf file to add the certificate files as well as the virtual host information for each domain. We have to replicate the configuration for each virtual host.

   <VirtualHost *:443>
        SSLCertificateFile /etc/pki/tls/certs/domainname.com.crt
        SSLCertificateKeyFile /etc/pki/tls/private/domainname.com.key
        SSLCACertificateFile /etc/pki/tls/certs/root-certificate.crt  
        ServerAdmin info@domainname .com
        ServerName www.domainname.com
        DocumentRoot /var/www/domainname .com/public_html/
        ErrorLog /var/www/domainname.com/logs/error.log
        CustomLog /var/www/domainname.com/logs/access.log combined
   </VirtualHost>

   In case we are using a commercial SSL certificate, and it is downloaded to /etc/pki/tls/certs, we have to make sure to that the SSLCACertificateFile value points directly to the root certificate. However, if the root certificate is in a “ca-certificates” bundle, we can exclude the SSLCACertificateFile line.
3. Next, we will restart Apache with this command:

   systemctl restart httpd

Install SSL Certificate: Apache on Debian & Ubuntu

1. First, we will edit the /etc/apache2/sites-available file to add the certificate file paths. Moreover, we have to replicate the configuration for each virtual host. Furthermore, we have to ensure SSLCACertificateFile value points directly to the ca-certificates.crt file.

   <VirtualHost *:443>
       ServerAdmin info@domainname .com
       ServerName domainname.com
       ServerAlias www.domainname.com
   
       DocumentRoot /var/www/html/domainname .com/public_html/
       DirectoryIndex index.html
   
       # SSL configuration
       SSLEngine On
       SSLCertificateFile /etc/ssl/certs/domainname .com.crt
       SSLCertificateKeyFile /etc/ssl/private/domainname .com.key
       SSLCACertificateFile /etc/ssl/certs/ca-certificates.crt  
       # Log files
       ErrorLog /var/www/html/domainname .com/log/error.log
       CustomLog /var/www/html/domainname .com/log/access.log combined
   </VirtualHost>
   <VirtualHost *:80>
       ServerName domainname.com
       ServerAlias www.domainname.com
       Redirect permanent / https://domainname .com/
   </VirtualHost>
2. Next, make sure the Apache SSL module is enabled, and then enable the virtualhost configuration as seen below:

   a2enmod ssl
   a2ensite domainname.com

3. Finally, restart Apache with this command:

   service apache2 restart
