Hi ppl,
I have been using apache as a local server for testing my html and php scripts. It was working fine for a month but now gives following error. I know nothing about networking so plz help me. Wat could be causing this problem?

[HTML]
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[/HTML]

Try the following (While apache is down)

netstat -an | grep ":80:

If this returns something like:
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

Then another webserver is already running.

Another thingie that might be wrong that you have to put the FQDN in the hosts file(/etc/hosts) (No not the nice way for you purists, i know, but it will get the job done for now). So take your fully qualified domain name (host.domain.com) and put it in the host file with the ip-address.

If it works now then there is a more nicer way, but that will require you to configure your resolv.conf correctly and that you host is in the DNS tables.

netstat -an | grep :80

gave the following output

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
tcp 0 0 59.94.208.110:3035 209.85.143.99:80 ESTABLISHED

Does that mean another instance of apache is running?
this is so weird !!! If apache is already running, y am i getting this problem? If its not apache, how to find out what it is?

I tried to kill apache with:

sudo killall -u www-data

Then i did
apache2ctl restart

It gave more errors:

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
httpd not running, trying to start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

do:

sudo netstat -anp | grep :80

and it will tell you the process listening

lsof -i tcp:80

Will show you what is using tcp port 80.


To kill it try kill -9 pid-number


The reason it wont start is because there is already a instance of apache running on port 80


For some reason it got hung up from the sound of it.

You might also want to look at older logs at the time this happened

yes. Indeed so. I recently installed the mysql apache module and by mistake i installed the apache1 module instead of apache2 which was already installed.
I dont know y aptitude installed apache1 to fulfill the dependencies instead of throwing an error...

Since u r on debian can u tell me how 2 remove all apache1 components? I tried it 1 by 1 but it gets very confusing.
Maybe u know better.
