apache2 start niet meer op

[no_player_4u]

Apache start niet meer op. Ik deed een upgrade van alle packages maar ik weet niet of het daar aan ligt.

Als ik apache met dit commando opstart:

/etc/init.d/apache2 start

krijg ik wel deze melding:

* Starting web server apache2 [ OK ]

Maar verder gebeurd er niks, geen process, geen foutmeldingen in de errorlog of syslog..niks.

Apache met dit commando opstarten geeft ook niks:

apache2ctl start

Ik heb ook even naar de datum van de binary gekeken maar zo op het eerste gezicht was die niet geupdate.

[mikeh]

Het lijkt me zowieso uitermate verstandig om je services te laten herstarten (of manual stop / start) na een update.

kill je apache2 pid handmatig;

ps -aux | grep apache

Dat leverd een getal op onder het rijtje "pid"

killall -9 pid_van_apache2

update if needed

En start apache dan via het init.d script.

[no_player_4u]

Dat is nou net het probleem het apache proces lijkt helemaal niet te starten. Ook niet bij het handmatig proberen te starten

Er lijkt op te starten en daarna meteeen weer gestopt.

En gezien het tijdstip van de apache binary is die bij het upgraden van het sytsteem, niet geupgrade.

Je ziet geen enkele melding van wat er misgaat.

Ik gebruik overigens Ubuntu Hardy

[roelp]

Wat staat er in je logfiles?

[Geert-Jan]

Ik gebruik overigens Ubuntu Hardy

Een debian versie was al vrij duidelijk, maar gebruik je op je vps/server ook nog een CP?

[no_player_4u]

Wat staat er in je logfiles?

Nee, staat helemaal niets, nergens komt er een melding bij behalve deze notice in de error log:

[notice] ModSecurity for Apache 2.1.5 configured - Apache/2.2.8 (Ubuntu) mod_defensible/1.2

[no_player_4u]

Een debian versie was al vrij duidelijk, maar gebruik je op je vps/server ook nog een CP?

Nee heb een vrij minimale installatie. Heb ook al gecheckt of misschien één van partities vol is, maar dat is ook niet het geval.

[Japje]

hoeveel vhosts heb je?

zorg dat alle huidige apache processes zeker weten weg zijn en doe:

strace /usr/sbin/apache2

en kijk waar hij eindigd (kan zijn dat je strace moet apt-get'ten.

[no_player_4u]

Voor zover ik met ps/top kan zien is er geen enkel proces en ook na een reboot is apache niet opgestart.

Ik heb twee vhosts, de default vhost die standaard by Ubuntu zit en me eigen.

Ik heb dit gedaan

strace /etc/init.d/apache2 start

ipv /usr/sbin/apache2

omdat ik anders deze foutmelding krijg: apache2: bad user name ${APACHE_RUN_USER}

deze wordt variable wordt namelijk in apache2.conf gezet.

hmzn, er is toch iets niet lekker want hij komt niet bij het openen van je vhosts, zelfs niet bij het openen van zn logs, vandaar dat je ook niets ziet.

enige wat ik zie wat het misschien zou kunnen zijn is iets met:

stat("/etc/apache2/mods-enabled/disk_cache.load", 0x7fffb1f40df0) = -1 ENOENT (No such file or directory)

daarna is het stil kwa modules. dus ik zou zeggen haal deze uit je mods-enabled en probeer het nog eens

[mikeh]

access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)

ld combines a number of object and archive files, relocates their data and ties up symbol references. Usually the last step in compiling a program is to run ld.

Bovenstaande zegt genoeg nietwaar.

Niet helemaal? Wat zegt het precies, en hoe zou ik dit kunnen oplossen?

[no_player_4u]

owja, dit geeft

# /usr/sbin/apache2 -X

[FransVanNispen]

Wat wij vaak zien is dat er een ander process apache verhindert te starten omdat het een poort in gebruik houdt.

Vaak helpt dit:

killall -9 exim
killall -9 httpd (of apache2)

en dan opnieuw starten

mijn apache draait prima zonder deze optionele files.

/etc/ld.so.preload
File containing a whitespace separated list of ELF
shared libraries to be loaded before the program.
libraries and an ordered list of candidate
libraries.

/etc/ld.so.nohwcap
When this file is present the dynamic linker will
load the non-optimized version of a library, even
if the CPU supports the optimized version.

Aan de hand van die eerdere strace denk ik nog steeds het het wellicht een brakke module is. Indien mogelijk maak een backup van je configs, doe een apt-get --purge apache2 en eventuele modules en installeer hem nog eens, configs terug zetten nog eens proberen
