I am trying to enable SSL for my webserver. However, when I enable ssl, http stops working and https does not start working. I have followed the following guide:

https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-14-04

There is no firewall activated on the server. This is the default-ssl.conf file:

<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
                ServerAdmin [email protected]
                ServerName MyWebSite.com
                ServerAlias www.MyWebSite.com

                DocumentRoot /var/www/html

                # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
                # error, crit, alert, emerg.
                # It is also possible to configure the loglevel for particular
                # modules, e.g.
                #LogLevel info ssl:warn

                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined

                # For most configuration files from conf-available/, which are
                # enabled or disabled at a global level, it is possible to
                # include a line for only one particular virtual host. For example the
                # following line enables the CGI configuration for this host only
                # after it has been globally disabled with "a2disconf".
                #Include conf-available/serve-cgi-bin.conf

                #   SSL Engine Switch:

                #   certificate chain for the server certificate. Alternatively
                #   the referenced file can be the same as SSLCertificateFile

                #   o FakeBasicAuth:
                #        Translate the client X.509 into a Basic Authorisation.  This means that
                #        the standard Auth/DBMAuth methods can be used for access control.  The
                #        user name is the `one line' version of the client's X.509 certificate.
                #        Note that no password is obtained from the user. Every entry in the user
                #        file needs this password: `xxj31ZMTZzkVA'.
                #   o ExportCertData:
                #        This exports two additional environment variables: SSL_CLIENT_CERT and
                #        SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
                #        server (always existing) and the client (only existing when client
                #        authentication is used). This can be used to import the certificates
                #        into CGI scripts.
                #   o StdEnvVars:
                #        This exports the standard SSL/TLS related `SSL_*' environment variables.
                #        Per default this exportation is switched off for performance reasons,
                #        because the extraction step is an expensive operation and is usually
                #        useless for serving static content. So one usually enables the
                #        exportation for CGI and SSI requests only.
                #   o OptRenegotiate:
                #        This enables optimized SSL connection renegotiation handling when SSL
                #        directives are used in per-directory context.
                #SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
                <FilesMatch "\.(cgi|shtml|phtml|php)$">
                                SSLOptions +StdEnvVars

                #   SSL Protocol Adjustments:
                #   The safe and default but still SSL/TLS standard compliant shutdown
                #   approach is that mod_ssl sends the close notify alert but doesn't wait for
                #   the close notify alert from client. When you need a different shutdown
                #   approach you can use one of the following variables:
                #   o ssl-unclean-shutdown:
                #        This forces an unclean shutdown when the connection is closed, i.e. no
                #        SSL close notify alert is send or allowed to received.  This violates
                #        the SSL/TLS standard but is needed for some brain-dead browsers. Use
                #        this when you receive I/O errors because of the standard approach where
                #        mod_ssl sends the close notify alert.
                #   o ssl-accurate-shutdown:
                #        This forces an accurate shutdown when the connection is closed, i.e. a
                #        SSL close notify alert is send and mod_ssl waits for the close notify
                #        alert of the client. This is 100% SSL/TLS standard compliant, but in
                #        practice often causes hanging connections with brain-dead browsers. Use
                #        this only for browsers where you know that their SSL implementation
                #        works correctly.
                #   Notice: Most problems of broken clients are also related to the HTTP
                #   keep-alive facility, so you usually additionally want to disable
                #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
                #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
                #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
                #   "force-response-1.0" for this.
                # BrowserMatch "MSIE [2-6]" \
                #               nokeepalive ssl-unclean-shutdown \
                #               downgrade-1.0 force-response-1.0

        </VirtualHost>
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

apache -S gives me:

AH00111: Config variable ${APACHE_RUN_DIR} is not defined apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

and apachectl -S gives me:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 192.168.178.24. Set the 'ServerName' directive globally to suppress this message VirtualHost configuration: *:80 192.168.178.24 (/etc/apache2/sites-enabled/000-default.conf:1) *:443 MyWebSite.com (/etc/apache2/sites-enabled/default-ssl.conf:2) ServerRoot: "/etc/apache2" Main DocumentRoot: "/var/www/html" Main ErrorLog: "/var/log/apache2/error.log" Mutex watchdog-callback: using_defaults Mutex ssl-stapling-refresh: using_defaults Mutex ssl-stapling: using_defaults Mutex ssl-cache: using_defaults Mutex default: dir="/var/run/apache2/" mechanism=default Mutex mpm-accept: using_defaults PidFile: "/var/run/apache2/apache2.pid" Define: DUMP_VHOSTS Define: DUMP_RUN_CFG User: name="www-data" id=33 Group: name="www-data" id=33

disabling ssl immediately gets http back up. (after a restart of Apache)

Unfortunately, I no longer know what I can try to do. any assistance here would be greatly appreciated!

Thank you in advance!

EDIT: As it is clear the information I've provided does not fully explain my issue, I am adding additional details here:

sudo service apache2 restart

Gives the following result:

Warning: The unit file, source configuration file or drop-ins of apache2.service changed on disk. Run 'systemctl daemon-reload' to reload units. Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details

systemctl daemon-reload

Runs successfully, but I still get the Job failed response when running the restart command again. Below is the response for "systemctl status apache2.service"

I have gone through all the suggestions in the thread you provided and the thread that this is listed as a duplicate of and neither of them seem to have anything that is helping me. Could you maybe elaborate a bit on why you believe this issue answers my question and how I can apply the answers in the thread to my situation? Again, thank you very much for taking the time to look at my issue and apologies if this is something very obvious.Adrian Liseth
I have no idea what you actually did by "going through all the suggestions in the thread" but the problem is that an environment variable is not defined since you've restarted apache the wrong way. To cite "This message is displayed because you directly executed the apache2 binary. In Ubuntu/Debian the apache config relies on the envvar file which is only activated.... ". Solution is also there: "...sudo service apache2 restart...".Steffen Ullrich
Apologies for that, I should be more specific. Thank you for explaining the relation between the issues. When I run sudo service apache2 restart, I get the following result: Warning: The unit file, source configuration file or drop-ins of apache2.service changed on disk. Run 'systemctl daemon-reload' to reload units. Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details. So I run 'systemctl daemon-reload' successfully and try restart again. but I still get the job failed message.Adrian Liseth
running "systemctl status apache2.service" gives: ubuntu systemd[1]: Starting The Apache HTTP Server... ubuntu apachectl[4299]: AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 192.168.178.24.

After a lot of searching I found out that it was due to my key being corrupt.

I was able to determine this by checking the apache error log:

sudo nano /var/log/apache2/error.log

As displayed, "Private key not found" was not referring to the path of the key, but rather the key being corrupt. I checked this by opening the key with:

sudo nano MyWebSite.key

If the key is correct, it will have the text

----- BEGIN PRIVATE KEY -----

at the top of the key. The solution was then to regenerate the certificate request, have the certificate re-issued and install the new certificate. I hope this helps you if you're in the same situation as I was.
