问题
I have no .htaccess file. I have index.php which has the following content and works beautifully in a browser like Chrome, or Safari:
<?php print "hello world"; ?>
When I load it in a browser I get: hello world. When I try any of the following I get ERROR 500: Internal Server Error.
- /usr/bin/wget http://example.com/index.php
- /usr/bin/wget -nv -t 5 --connect-timeout=4 -w 4 --connect-timeout=20 -nd --no-cache --no-cookies http://example.com/index.pp
- /usr/bin/wget --content-on-error http://example.com/index.php
- /usr/bin/wget --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0"
- curl http://example.com/index.php
I checked all apache log files and can see nothing there at all except for when I load it in a webrowser.
This is Ubuntu 16.04 php7.0 Apache2. All freshly installed and updated and the laest version as of Nov 3rd 2016
I tried reinstalling wget. I tried wget from other machines and the local machine.
I have tried putting varnish on port 80 and apache on port 8080 behind varnish... that didn't change anything.
Wget outpus the following with debug:
root@one:~# wget --debug http://example.com/index.php

It can happen that your apache is not accepting any useragent from curl or wget. This can be configured from httpd.conf file (or may be some other place, not have much experience on that).
If you use the useragent of your browser with wget or curl, it should work with you. For example:
wget -U "Opera 11.0" http://www.test.com/
curl -A "Opera 11.0" http://www.test.com/

I noticed another domain name on the server worked. So, I copied the vhost, reloaded apache and it still was not working. I made everything exact. In the end I saw DNS was pointed to my dev server which was not listening for my domain name and returning an error 500.
Updated DNS and the show is back on. Thanks for working me through things with ideas!
