Apache SSL Remotestorage Server Not Working

196 views Asked by At

I am trying to set up my Ubuntu web server to host a remotestorage server utilising the php-remote-storage server.

I have not setup SSL on my server before, so a fresh-ish apache2 install is present. I've followed the instructions to the letter, jusr replacing all occurances of storage.local with my own subdomain, lets call it sub.example.com .

sub.example.com is directed to my web server from AWS Route 53. This works for other.example.com

So when I browse to sub.example.com it just times out. Chrome says:

This site can’t be reached

sub.example.com unexpectedly closed the connection.

Try:

Reloading the pageChecking the connection

ERR_CONNECTION_CLOSED

I dont know how to find out what's wrong. All other hosted sites work so I'm guessing im doing something wrong with the SSL bit.

Thank you.

        #        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

        #        exportation for CGI and SSI requests only.
        #   o OptRenegotiate:

        #   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.

I had some troubles getting it up as well. Some of my problems were due to:

You have to replace 'ServerName storage.local' by your actual hostname. That certificate will fail for any other hostname.

Also, if you haven't generate the SSL encryption keys, the apache2 server will fail to load once it tries to load the certificates specified by your config file. Specifically:

SSLCertificateFile /etc/ssl/certs/storage.local.crt
SSLCertificateKeyFile /etc/ssl/private/storage.local.key

Also, you want to disable (a2dissite) the different websites that specify a DocumentRoot different from /var/www/php-remote-storage/web

After observing these steps, I got it running.

Now I wanted to know how to host 2 webservices at the same time, with different DocumentRoot folder, through the same port (443), with with some different alias (like: server.com/nextcloud and server.com/privatestorage).
