[debian lenny] apache2 is niet meer bereikbaar

[Feanaro]

Sinds mijn tweede NIC van mijn thuisserver het begeven leek te hebben, heb ik dit opgelost door mijn wireless router (voorheen alleen access point) als gateway te gebruiken. De server hangt nu met z'n enkele NIC achter de router.

Op de server (debian lenny) draaien verschillende daemons, o.a. een SSH, FTP en webserver. Ik beschik over een eigen domeinnaam die sindsdien gekoppeld staat aan het IP-adres van de router. SSH en FTP werken sindsdien weer naar behoren, maar mijn Apache2 server (met meerdere virtual hosts) komt niet meer in contact met de buitenwereld. Alleen de [localIP]/phpmyadmin lijkt nog te werken (enkel lokaal).

In mijn error.log waarvan hieronder een deel is opgenomen, staat steeds een verwijzing naar /htdocs. Aangezien er niet zo'n directory bestaat op m'n server, zocht ik op Google en vond een verwijzing naar een forum waar werd gesproken over het vermelden van DocumentRoot bij alle virtual hosts. Deze waren bij mij al gedefinieerd. Verder zei men dat er in /etc/apache2/apache2.conf geen DocumentRoot gedefinieerd stond. Deze heb ik erin gezet als /var/www/, dat is de parent directory waarin de virtual hosts hun DocumentRoots hebben.

Nu kan ik wel mijn server vinden, maar hij geeft voor alle virtual hosts de "It works!" default pagina, de pagina's van de virtual hosts zijn niet bereikbaar. Deze "oplossing" zorgt er dus wel voor dat apache bereikbaar is, maar is geen echte oplossing voor mij.

Onderstaand het laatste stuk error log.

[Feanaro]

Er wordt ook ergens gesproken over een oplossing: het IP-adres "hard" in de virtual hosts config inkloppen, maar aangezien mijn IP soms nog wel eens wil veranderen, is dit niet echt een oplossing...

Er blijft iets geks aan de hand met die virtual hosts...

[Emperor_]

Misschien handig als je erbij kan posten hoe je virtual host config eruit ziet en via welke dns namen je deze gaat aanspreken. Mogelijk geeft dit wat meer duidelijkheid over je configuratie.

Je zegt dat apache niet meer beschikbaar is voor de buiten wereld, bind apache wel op de juiste interface en staan je port forwardings in je router wel goed ?

[pennywiser]

Is lastig te zeggen zo. Gaan meerdere dingen mis geloof ik. Graag al je logs en configs posten. Oa. ook de vhost config.

[Feanaro]

Port forwardings staan goed, apache staat bij mijn weten niet op een specifieke interface... In het verleden was hij altijd zowel intern als extern te bereiken. Nu ook, want door die DocumentRoot in mijn apache2.conf te zetten, kan ik er van buiten ook bij, ware het niet dat ik niet bij de verschillende vhosts kan. Daar lijkt me dus iets mee mis.

Zal de rest van de logs en config plaatsen.

Access.log is leeg...

De rest is vergelijkbaar met de tweede, alleen is er telkens een andere naam en Directory gedefinieerd.

Bij het starten geeft hij:

Maar dat was altijd al, ook toen alles nog wel werkte. Heb er daarom nooit acht op geslagen.

in apache2.conf heb ik volgens mij niets aangepast, dit is de standaard die met debian/lenny (of etch daarvoor) meekwam:

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to

# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
# Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# /usr/share/apache2/error/include/ files and copying them to /your/include/path/,
# even on a per-VirtualHost basis. The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.

[Emperor_]

Ik zou het volgende proberen voor je virtual hosts. zo ver ik kan zien is je apache config verder prima.

NameVirtualHost *

<VirtualHost *:80>
DocumentRoot /var/www/willemshome.net/
ServerName www.willemshome.net
<Directory "/var/www/willemshome.net/">
allow from all
Options -Indexes
</Directory>
</VirtualHost>

<VirtualHost *:80>
DocumentRoot /var/www/files/
ServerName files.willemshome.net
<Directory "/var/www/files/">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

Ik durf niet te zeggen of dit nu helemaal correct is, maar zo zou ik het uit me hoofd eens proberen. Zie tevens: http://httpd.apache.org/docs/2.0/vhosts/

[Feanaro]

Dit werkt wel, maar nu krijg ik maar één virtuele host te zien. Alle virtuele hosts verwijzen naar de inhoud van één enkele vhost!

[Feanaro]

Heb nu zoals in de link die je stuurde alle virtual hosts opnieuw gedefinieerd en de oude verwijderd.

Nu leek hij het even te doen, maar na een keer een pagina laden, blijven alle pagina's wit hier. Op afstand kreeg iemand een 101 error bij het openen van een van m'n pagina's.

Error log gecheckt, zie hier:

[Emperor_]

Zo te zien aan je log files draait er al iets op port 80, controleer of deze al in gebruik is en hoe je Listener precies staat ingesteld. Het lijkt daar dus niet helemaal goed te gaan.

[Feanaro]

bavaria:/home/ralf# lsof -i TCP:80

.

Ik heb de "Listen 80" uit de virtual hosts file gehaald. Wellicht zat deze ergens dubbel, hoewel ik nergens anders een verwijzing heb kunnen vinden. Hierna was de foutmelding wel weg.

Vervolgens heb ik stap-voor-stap de virtual hosts weer geactiveerd. Ze lijken het nu weer te doen. Vind het nog steeds vreemd dat hij het in ene niet meer deed. Jarenlang heeft hij op de oude configuratie - waar volgens mij niet zo veel anders aan was dan aan deze - gedraaid.

Bedankt voor jullie feedback!

[Emperor_]

Je schrijft over twee netwerkkaarten, mogelijk dat je dns mogelijk nog verwees naar je ouder netwerkkaart. Mogelijk dat daardoor reverse lookups en hostname niet goed werkte. Goed dat het is opgelost!

De fout die je maakte zat hem in je Virtual host configs waarin je hem alleen liet luisteren op een specifiek IP (je externe ip die hoort bij www.willemshome.net). Nu in de nieuwe situatie moet je hem op je nieuwe interne IP laten luisteren. De suggestie die Emperor_ deed laat de Vhost luisteren op elk IP.

Je moet dus gewoon de docs lezen en leren hoe je en virtual host setup maakt.
