Apache Won't Start after Adding SSL Certificates - apache

Question

Hello so here is the problem
I have generated CSR on CentOS and purchased SSL on Comodo.
I have added following lines to ssl.conf
ServerName mydomain.com
DocumentRoot /var/www/html
SSLEngine on
SSLCertificateKeyFile /etc/pki/tls/certs/mydomain.key
SSLCertificateFile /etc/pki/tls/certs/mydomain.crt
SSLCACertificateFile /etc/pki/tls/certs/mydomainCA.crt
and following lines to httpd.conf
<VirtualHost *:80>
ServerName thedomain.com
Redirect "/" "https://thedomain.com/"
</VirtualHost>
After this when I do systemctl restart httpd it gives me following error:
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl
-xe" for details.
and when I check journalctl -xe for details this is what it reads:

-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel

So I have checked lot os solutions but this problems still exists, please note that when I comment out all changes in httpd.conf and ssl.conf apache starts working back normally.
Thanks all in advance

Answer 1

SOLVED
Renaming file to PEM helped the case, besides this I came across some other issues that were causing error ( looking ata apache logs helped me to solv them )
Memory for apache was full so I had to increase it.
I had duplicated SSLCertificateKeyFile in the ssl.conf file and I commented out the default file link.
