Multiple proxy:errors in /var/log/apache2/error.log

  • 772

I am not sure where these warnings are for/concerning. Should I be worried about them or just ignore them as people are trying to connect to my server? Proxy Mod is already enabled, however I am less concerned about this and more the fact my apache instance is showing random ip's and web addresses that are trying to be proxied :?

  1. I guess you have enabled proxy module. You need to disable it with

    a2dismod proxy

    May be there are some other mod's you need to disable. To see what else modules you can (should) disable check output of

    apache2ctl -M

  2. Ok here how to enable mod_proxy.

    a2enmod proxy
a2enmod proxy_http
a2enmod proxy_balancer
a2enmod lbmethod_byrequests
systemctl restart apache2

    Apart from your proxy you need to have one (or more) http-servers that deliver the content.

    http://10.10.0.100 - Proxy Server

    http://192.168.0.11 - Content Server

    Edit /etc/apache2/sites-available/000-default.conf and change virtualhost section to

    <VirtualHost *:80>
    ProxyPreserveHost On

    ProxyPass / http://192.168.0.11/
    ProxyPassReverse / http://192.168.0.11/
</VirtualHost>

    Restart Apache

    systemctl restart apache2

    Now if you access your proxy server (http://10.10.0.100) in a web browser, you will see the response of your backend server (http://192.168.0.11)
