That means you didn't started the zabbix server process.

Greetings

i had the same problem when i used slackware with openwall kernel patch. it's because of security issues provided by this patch.

gentoo, not slackware

Thanks for the quick replies.

But both of you two are telling me things that do not seem to be useful.

Especially the reply from erisan is not helpful because rc-status tells me that the processes are running.

And "openwall kernel patch" just says nothing to me. How could I find out if this is my problem?

cu :-)

**epifanova** · 31-05-2006, 10:29

which OS do you use?
zabbix_server and frontend runnig under one user or under different users?

**toffelsen** · 31-05-2006, 10:46

Yes, I do have installed this now on a new GENTOO. Zabbix server and frontend - I do not understand, what you are asking. Where did I configure this?

Hi shabo,
I do not think now, that my GENTOO has this Owl. Is there a way to find out if I really have no Owl?

**shabo** · 31-05-2006, 12:19

if you had not patched your kernel - you don't have it. i gave you the wrong link earlier. right one is: http://www.openwall.com/linux/

earlier was to complete distro called openwall. above is to kernel patch. sorry

Re: ZABBIX server is running - - No

> ZABBIX server is running - - No

The Zabbix GUI tries to figure out wether the server process is running by using the ps command:

> [include/config.inc.php, line 1846]
> if( (exec("ps -ef|grep zabbix_server|grep -v grep|wc -l")>0) ||
(exec("ps -ax|grep zabbix_server|grep -v grep|wc -l")>0) )

This statement is run when the PHP script is executed, ie. when the web server gets a request for report1.php (which includes config.inc.php). There can be several reasons why this might fail, eg:
* the web server can't run the ps command due to access control restrictions
* the system doesn't allow users to view processes of other users
* the web server runs chroot(2)ed and doesn't have access to ps

There are (at least) two ways to fix the message:
* make sure the web server can run ps(1) and see the zabbix_server process
* use some different method to figure out if zabbix_server is running

\B.

No, I did not patch my kernel. It´s just build by genkernel - if you know what I mean. Not all are familiar with the gentoo things.

Good morning and thanks again for helpful hints.
But how do I

make sure the web server can run ps

?
And second: Do you mean something like rc-status? Because here the zabbix_server ist shown as running.

**toffelsen** · 01-06-2006, 09:31

Zabbix ~ # ps -ef|grep zabbix_server|grep -v grep|wc -l
0
Zabbix ~ #

Is it that what you mean?

Yes, if you can't find zabbix_server when you run ps(1) on the command line, that would explain why the Web-GUI thinks the server is not running.

I can only give you general advice, because everyone's setup is different. I've never touched Gentoo (afaik :-) and don't know about their specifics.

First make sure that your ps(1) works from the command line.
Then make sure that ps(1) also works when called from the GUI (ie, running as a sub-process of your web server, which is usually apache)

If these two conditions are met, Zabbix should appear as running in the GUI.

Best luck!

And second: Do you mean something like rc-status? Because here the zabbix_server ist shown as running.

No, I was thinking that the zabbix_server could store some sort of I'm alive data in the database (say every 30sec), which the GUI can check. This would require changes to both zabbix_server and the GUI and needs to be done by the Great Zabbix Developer Team (if they decide to follow this path). Of course, there may be other ways to implement it, too.

I found it.
I had a wrong password in my /etc/zabbix/zabbix_server.conf

Database host name
# Default is localhost

DBHost=localhost

# Database name

DBName=zabbix

# Database user

DBUser=zabbix

# Database password
# Comment this line if no password used

DBPassword=passposs
