= Debugability =
Debugging app install issues is very important, so any time something permanently destructive is attempted, it should be done with care to preserve the ability to analyze and debug what happened:
* preserve Preserve as much as possible from the existing (buggy) environment
* Make sure httpd configuration is sane (result should be "'''Syntax OK'''"):
* The idea is to not delete anything permanently - copy or move things to, say, a folder in /tmp if you have to get something out of their place. For example:{{code| mkdir /tmp/app-debug/}}
* Then add things there as necessary for later analysis, like: cp -a /var/log/amahi-app-installer.log /tmp/app-debug cp -a /etc/httpd/conf.d /tmp/app-debug
* Copy of the app install logerror and access logs (i.e. Adminer is the app):{{Code|tail cat /var/hda/web-300 apps/adminer/logs/error.log cat /var/loghda/amahiweb-app-installerapps/adminer/logs/access.log <nowiki>|</nowiki> fpaste}}
* Copy of the app error and access logs To check if process is running (replace '''appname''' with app directory, i.e. sabnzbdsab is the app):{{Code|cat /var/hda/web-apps/appname<blockquote><u>Fedora</logsu></error.logblockquote>cat /var/hda/web-apps/appname/logs/access.log}} ps guax | grep sab | fpaste
