apache2 - testing if the VirtualHost is working

In this short article we would like to show how to check with curl command if VirtualHost is working under Apache2 server correctly.

Presented approach uses fact, if we have set many domains under one apache2 instance, we can send Host: my-domain.com header that switches between domains under same server.

Note: check if curl is installed - you can use Windows or Linux Bash.

Run following command:

curl '88.77.44.200' -H 'Host: my-domain.com' --compressed --insecure

Where:

  • 88.77.44.200 should be replaced with your server ip address of machine with apache2,
  • my-domain.com should be replaced with domain configured in VirtualHost.

Example output:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

Apache2 configuration

Example /etc/apache2/sites-enabled/my-domain.com.conf file content:

<VirtualHost *:80>
        ServerName my-domain.com
        ProxyPreserveHost On
        ProxyPass / http://127.0.0.1:8080/
        ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>
