I'm trying to install ssl certificate on a new linode machine with centos 7. I installed httpd and open_ssl. I followed this guide for apache: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-centos-7

And this one https://www.digitalocean.com/community/tutorials/how-to-create-an-ssl-certificate-on-apache-for-centos-7 for creating a certificate ssl.

Now when I try to restart apache with this command:

systemctl restart httpd.service

I got this error:

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

If I run the first script I get this:

httpd.service - The Apache HTTP Server

    What happens when you run httpd in bash? – daisy Mar 3 '17 at 10:28
  • AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 2a01:7e00::f03c:91ff:fee5:538f. Set the 'ServerName' directive globally to suppress this message – Allen Walker Mar 3 '17 at 10:58
  • Can you post the output of "apachectl configtest"? – StefanR Mar 3 '17 at 12:46

    Yes I think it's a problem in configuration, you have an error somewhere in your configuration files. – Hamza Jabbour Mar 5 '17 at 8:36
