Dotaz: Apache2 (Gentoo Linux) se "nechce" spustit

[Martin Gates]

Dobrý den,
můj problém je tento:

root@localhost # apache2
(99)Cannot assign requested address: make_sock: could not bind to address 127.0.0.1:80
no listening sockets available, shutting down
Unable to open logs

root@localhost # rc-config start apache2
* Starting apache2 ...  [ !! ]

# cat /etc/conf.d/apache2
...
APACHE2_OPTS="-D DEFAULT_VHOST -D SSL_DEFAULT_VHOST -D INFO -D LANGUAGE -D MANUAL -D SUEXEC"
...

# netstat -ldp | grep :80
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 *:8010                  *:*                     LISTEN      6426/kopete
udp        0      0 *:8010                  *:*

Když do /etc/apache2/httpd.conf dopíšu "Listen 80", tak to sice nic nenahlásí, ale stejně se nemůžu připojit na http://127.0.0.1:80 (Server timeout).

Byl bych vděčný za (téměř) jakoukoli radu, díky !

Tak veru, hod sem logy. A apache bez ssl a tych hovadin, co tam mas ide ci nejde? Ak skusis tvoju lokalnu adresu, tak ide ci nejde? Takisto sem hod USE flags, s ktorymi si apache skompiloval. A skus takisto cez apachectl spustit apache.

[Martin Gates]

# emerge -vp apache
net-www/apache-2.2.4-r7  USE="debug doc -ldap -mpm-event -mpm-itk -mpm-peruser -mpm-prefork -mpm-worker -no-suexec (-selinux) -ssl -static-modules -threads" 0 kB

# apache2ctl start
 * Starting apache2 ...  [ !! ]

Listen *:80

Skus toto, na jednom fore to rozoberali a takto to vyriesil.

[Martin Gates]

Ano, toto jsem zkoušel už dřív, výsledkem je to, že si to nestěžuje (pokud ostraním "D DEFAULT_VHOST" z APACHE2_OPTS v /etc/conf.d/apache2), ale pořád se nemůžu připojit na http://127.0.0.1:80 -- Server timeout.

[oxymoron]

no inak ked si vsimnes tak ten netstat si nezvolil moc dobre lebo poprve netstat -l ti da iba tie co su listening -- co ked tam je nieco conectnute ESTABLISHED !! dalej ked das netstat bez -n tak ti to nepise cisla portov takze grep :80 ti je nanic (malo byt grep :http) takze to pusti radsej takto:

netstat -atpn |grep :80 a tak si over ci tam naozaj nieco nebezi

[Martin Gates]

Díky za radu. Takže novinky:

Jak je vidět, apache běží. Došla mi trpělivost a celý jsem to smazal se všema konfama, a přeinstaloval, teď se to spustí, ale:

http://localhost ==> Timeout on server
http://127.0.0.1 ==> Timeout on server

[Jooky (inactive)]

- Mas v poriadku loopback rozhranie ?
- nastavoval si uz netfilter (iptables) ?
- nemas nahodov proxy v prehliadaci ? (skus telnet 127.0.0.1 80)

[Martin Gates]

Loopback jsem měl vypnutý (viz níže), iptables mi nefunguje a proxy nastavený nemám.
Tím se nabýzí otázka:

# iptables -L
FATAL: Module ip_tables not found.
iptables v1.3.5: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

[Martin Gates]

Takže ten "Timeout on server" jsem způsobil tak, že jsem neměl spuštěnej init script net.lo, důvodem (možná) bylo toto:

# cat /etc/conf.d/rc
...
RC_PLUG_SERVICES="!net.*"
...

(Mám totiž notebook a nechtěl jsem spouštět net.* při bootu)

Řešení:
/etc/conf.d/rc: RC_PLUG_SERVICES="net.lo !net.*"
rc-update -a net.lo boot
