Obligatory - none of the previous answers worked for me. I inherited a strange combination of IP address-based virtual hosts and * vhosts (not assigned/catch all IP addresses) based virtual hosts in this Apache configuration messed up by ISPConfig.
I wanted Apache to serve not configured hosts with the same page.
I had: not configured hosts went to the first vhost after 000-default.conf
. No matter I had *:80 catch all defined as the first vhost, instead of default Apache would load first defined site:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
</VirtualHost>
Although it's not completely valid configuration, what finally worked was adding an IP address-based virtualhost without ServerName/ServerAlias defined:
<VirtualHost 192.168.10.10:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
</VirtualHost>
<VirtualHost 192.168.10.10:443>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
SSLEngine On
...
</VirtualHost>
$ apachectl -S
outputs IP address-based vhosts first, and * based vhosts later, and finally my default site is loaded before real site:
AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/000-default.conf:50
192.168.10.10:80 is a NameVirtualHost
default server server.tld (/etc/apache2/sites-enabled/000-default.conf:34)
port 80 namevhost server.tld (/etc/apache2/sites-enabled/000-default.conf:34)
port 80 namevhost some-site.tld (/etc/apache2/sites-enabled/100-some-site.tld.vhost:7)
...
46.23.86.103:443 is a NameVirtualHost
default server server.tld (/etc/apache2/sites-enabled/000-default.conf:38)
port 443 namevhost server.tld (/etc/apache2/sites-enabled/000-default.conf:38)
port 443 namevhost some-site.tld (/etc/apache2/sites-enabled/100-some-site.tld.vhost:182)
...
*:80 is a NameVirtualHost
default server server.tld (/etc/apache2/sites-enabled/000-default.conf:1)
port 80 namevhost server.tld (/etc/apache2/sites-enabled/000-default.conf:1)
Word of notice - in a configuration like this, * vhosts won't work, so you need to apply IP addresses to all vhosts.
