apache is not running..

[aswantara]

i have installed zabbix 1.4.2 in my computer. Zabbix has been running, but it has a problem with apache. Apache detected not running, and when i restarting apache, there is a message "Could not reliably datermine the server's fully qualified domain name, using 127.0.1.1 for ServerName httpd (pid 13992) already running"

Anyone has been solved this problem?
thank's.

Hi

What's your's OS? Maybe your's apache is not running a httpd user, in debian and ubuntu apache is running by www-data user.
Then I check like this -> net.tcp.port[my_ip,80] or net.tcp.port[my_ip,443] is apache listen to standard port www,https

I have already set the user in apache.conf by www-data, but apache still not working same like above.. So what must i do?

The apache server is probably running. What is the output from the following command:

# ps -e|grep httpd

(does it echo back server processes?)

2338 ? 00:00:11 httpd
31707 ? 00:00:30 httpd
31708 ? 00:00:27 httpd
31709 ? 00:00:33 httpd
31710 ? 00:00:28 httpd
31711 ? 00:00:32 httpd
31712 ? 00:00:30 httpd
31713 ? 00:00:32 httpd
31714 ? 00:00:32 httpd


If you see process like the above, Apache might not be configured to listen the external IP address (maybe listening to localhost only?) thus preventing any external port 80 monitoring by Zabbix.

ptader@host:~$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.

Connection closed by foreign host.

ptader@host:~$ telnet host.company.com 80
Trying 192.168.0.1...
telnet: connect to address 192.168.0.1: Connection refused (Opps, nothing listening on port 80)
telnet: Unable to connect to remote host: Connection refused
ptader@host:~$

when i create a command ps -e|grep httpd, there are no viewing..

Correct.

There is one last check you can do. In your original post the error message indicated that apache was already running with PID 13992. Run this command to see if that is true:

# ps -ef|grep 13992

If this echo's nothing, then

# ls /var/run/apache2.pid

If this file exist AND apache isn't running, delete it and try restarting apache.

This may sound like a stupid and obvious answer but have you double-checked your httpd.conf file?

ServerName localhost:80

Also check your /etc/hosts file to ensure that you have that set up properly.

ip address localhost.localdomain localhost

Just trying to help brainstorm.

to ptader,,
i have checked #ps -ef|grep 13992
and the output is like this :

root 6927 6864 0 11:37 pts/1 00:00:00 grep 13992

and then i have deleted the apache2.pid, but there is an error, like this :
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
httpd (no pid file) not running
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 [::]: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
[fail]

hos can be like that?
sorry, i am very beginner using zabbix..
thank's..

[cbidwell]

What about changing your loopback address to an actual loopback of 127.0.0.1 instead of 127.0.1.1?

[woger]

OK,

I set debug mode to 4 and got this message in the log:
50775:20090928:201310 Requested [net.tcp.service[http]]
50775:20090928:201310 TCP expect error: *** Cannot connect to [127.0.0.1]:80 [Connection refused]
50775:20090928:201310 Sending back [0]

I then added "Listen 127.0.0.1:80" to the httpd.conf and now it works.
