Determine offending file when running Apache's configtest

  • 772

Is there a way to determine the offending file when running https configtest.

For example, instead of:

Warning: DocumentRoot [/var/www/whatever.com/webroot] does not exist
Warning: DocumentRoot [/var/www/example.com/webroot] does not exist

I could see:

Warning: DocumentRoot [/var/www/whatever.com/webroot] does not exist in /etc/httpd/conf.d/file.conf
Warning: DocumentRoot [/var/www/example.com/webroot] does not exist in /etc/httpd/conf.d/other_file.conf

I reviewed help/man and searched, but could not find an option or equivalent command.

apache-2.2

  1. Unfortunately, apachectl does not offer this information.

    Your best solution is to simply use grep to search the config files for the string shown in the error message.

  2. Just to add a little of extra info, the apachectl script doesn't do much on its own, just invokes the httpd binary with a flag:

     configtest)
    $HTTPD -t
    ERROR=$?
    ;;

    So this has to be addressed in the core itself.

    This is fixed in apache-2.4:

    # systemctl status httpd
httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)
   Active: failed (Result: exit-code) since Fri 2014-06-20 20:36:01 CEST; 1s ago

    The relevant code is in server/config.c.

  3. Based on this tutorial check /etc/apache2/extra/httpd-vhosts.conf. This worked on my machine which is OSX 10.13 using Apache 2.4.
