Apache VirtualHost redirection from different subdomains - apache

Question

I have a DO droplet (Ubuntu 18.04) on which I want to host two sites. Let's say the droplet has an IP of 101.1.1.1. Now I want the sites to be pointed from another server (with different IP, let's say 104.1.1.1.) subdomain. Let's say siteone.example.org and sitetwo.example.org. So I follow the guides and set my Apache VirtualHost like this:
<VirtualHost *:80>
ServerAdmin webmaster#example.org
ServerName siteone.example.org
ServerAlias www.siteone.example.org
DocumentRoot /var/www/siteone/public_html
<Directory /var/www/siteone/public_html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
However, when I press siteone.example.org in my browser I get no response. I've set A name in both to point ends to point to 101.1.1.1. Is there something I'm doing wrong?

Answer 1

You want 2 web sites on the same machine, each with an IP address? So:
configure both IP on your system
Set both IP:80 in Listen
Configure one VirtualHost per IP / domain
Like so:
Listen *.80
<VirtualHost 101.1.1.1:80>
ServerName siteone.example.org
ServerAlias www.siteone.example.org
ServerAdmin webmaster.example.org
DocumentRoot "/var/www/siteone/public/html"
<Directory /var/www/siteone/public_html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/siteone_error.log
CustomLog ${APACHE_LOG_DIR}/siteone_access.log combined
</VirtualHost>
<VirtualHost 104.1.1.1:80>
ServerName sitetwo.example.org
ServerAlias www.sitetwo.example.org
ServerAdmin webmaster.example.org
DocumentRoot "/var/www/sitetwo/public/html"
<Directory /var/www/sitetwo/public_html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/siteotwo_error.log
CustomLog ${APACHE_LOG_DIR}/sitetwo_access.log combined
</VirtualHost>
In your DNS, configure:
101.1.1.1 siteone.example.org www.siteone.example.org
104.1.1.1 sitetwo.example.org www.sitetwo.example.org
