Apache virtual host from GET url - apache

<VirtualHost *:80>
ServerAdmin admin#example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Above is the example of https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-14-04-lts which I've followed to setup some sites. But what I wanna do is basically:
www.example.com?site=mynewsite.com
With htaccess: www.example.com/mynewsite.com
<VirtualHost *:80>
ServerAdmin admin#example.com
ServerName example.com/mynewsite.com
ServerAlias www.example.com/mynewsite.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Sadly above doesn't work.
Reason why I wanna do this is because I want to generate a website using database which will be triggered based of URL.
How may I do?


You could try the obscure ServerPath directive, which maps a request to a virtualhost based on the first component of the URL path.

Ubuntu 18 Point two domains to same folder

I've a server installed with Ubuntu 18.04 and on that server I've created new host for a new sub-domain:
api.example.com
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName example.com
ServerAlias api.example.com
DocumentRoot /var/www/searchcore
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Now I would like now to add another sub-domain "newapi.example.com" and I would like it to point to the same folder of the first domain (/var/www/searchcore).
Any idea how to do it?
Thanks

The ServerAlias directive accepts one or more names, so you can simply append the name of your new sub-domain to the existing ServerAlias directive like this:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName example.com
ServerAlias api.example.com newapi.example.com
DocumentRoot /var/www/searchcore
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Alternatively, you can also have multiple ServerAlias directives:
...
ServerAlias api.example.com
ServerAlias new.example.com
...

meta tags not showing up in fb-messenger&discord ect... -> when using https

So I recently updated my server from ubuntu 16.04 to 18.04 (full reinstall)
Now I'm having the following issue:
When using https no site will embed images or meta tags

^ same problem with facebook-messenger
Here is my /etc/apache2/sites-enabled/000-default.conf

SSLCertificateKeyFile /home/merijn/Certs/melijn.com.key
</VirtualHost>
You can visit the sites fine btw:
https://melijn.com
http://melijn.com
I hope there is a solution :)

Ok so the problem was the following:
I had an incomplete certificate and I needed to add a .ca-bundle file in my configuration.
So I added this line:
SSLCertificateChainFile /path/to/file.ca-bundle

Apache2: 2 virtual hosts with subdomains not working

I have set up one conf file in apache with 2 virtual hosts:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName test.domain.com
WSGIScriptAlias / /var/django/test/test/wsgi.py
<Directory /var/django/test/test>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
<VirtualHost *.80>
ServerAdmin webmaster#localhost
ServerName domain.com
#ServerAlias *.domain.com
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
But unfortunately only the first one is being called no matter what domain I put into the browser.
My expectation is that only test.domain.com will open my Django project and all other subdomains use the standard website.
What did I do wrong?
Regards
Kev

The error is here:

Apache 2.4 Restrict SSL to specific subdomain Vhosts

I have a single digitalocean droplet, with only a single IPV4 address possible. I would like to use SNI to apply TLS (SSL) encryption onto only a specific subdomain, and not any other parts of the domain.
Example being:
domain.com (No TLS)
sub.domain.com (TLS, certificate 1)
sub1.domain.com (TLS, certificate 2)
sub2.domain.com (no TLS)
I'm using LetsEncrypt for the certificates, so wildcard domains are not possible.
domain.com.conf
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName domain.com
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
sub.domain.com
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerAdmin webmaster#localhost
ServerName sub.domain.com
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLEngine on

Two things you should be aware of:
You never know which protocols users are going to use. They will default to http if protocol not defined and some browser extensions will try https first and use that if it exists.
Apache will fallback to the first site defined for that port if there's not a better match. In which case you might end up serving the wrong site if, for example, you don't define a sub2.domain.com site on port 443.
So you should define all 4 domains on both port 80 and port 443 and basically have 8 vhosts defined.
This also means will need to buy (or get for free from LetsEncrypt) certificates to cover all domains and not just the two you want to serve over https.
Then you should use redirects appropriately:
domain.com (No TLS): Serve site on port 80. Config for port 443 should just redirect all traffic back to equivalent page on http://domain.com
sub.domain.com (TLS, certificate 1): Serve site on port 443. Config for port 80 should just redirect all traffic back to equivalent page on https://sub.domain.com
sub1.domain.com (TLS, certificate 2): Similar to sub.domain.com setup mentioned in point 2 above.
sub2.domain.com (no TLS): Similar to domain.com set up mentioned in point one above.
Example config:
<VirtualHost *:80>

However if going to all this hassle then might want to rethink not serving everything over https.

Host two different sites in apache

I have one Linux server with Apache installed. I configured two sites in it using VirtualHost.
I configured the two VirtualHosts for two different domain names. The configuration looks like this:
<VirtualHost 12.123.123.123>
ServerAdmin info#example-one.com
ServerName example-one.com
ServerAlias www.example-one.com
DocumentRoot /var/www/html/example-one
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
<VirtualHost 12.123.123.123>
ServerAdmin info#example-two.com
ServerName example-two.com
ServerAlias www.example-two.com
DocumentRoot /var/www/html/example-two
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
When I visit my site example-one.com, then I see the correct website.
But when I visit example-two.com, then I see the website of example-one.com.
What am I doing wrong? I'm trying to host those two different websites under the same Apache server.

Do you have NameVirtualHost directive somewhere in your httpd config file?
This should work. Be aware that the first VirtualHost block is the default in case the http request does not match any other VirtualHost block.
For reference https://httpd.apache.org/docs/2.2/mod/core.html#namevirtualhost
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin info#example-one.com
ServerName example-one.com
ServerAlias www.example-one.com

CustomLog ${APACHE_LOG_DIR}/access.log combined
