ZabbiX Server does not start, zabbix_server.log almost empty. How to debug?

[okoester]

Hi together,

I'm currently working on a very strange problem.

I'm trying to install Zabbix Server 2.2.1 on FreeBSD inside a jail.
Installation was startet from Portstree with

make install clean; rehash

That all works fine for me. Everything went as expected.
I also installed zabbix-frontend and MySQL 5.5 together with php-fpm and nginx.

The DB was set up as mentioned, web frontend came up and running afer some small problems. (nginx is running under user www).

I started zabbix_server with

#> service zabbix_server start

and all seemed well. But zabbix frontend told me that server was not running. So I checked with

#> service zabbix_server status
zabbix_server is not running.

So I checked Port 10051 on that jail and found

#>  telnet 127.0.0.1 10051
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host

then

 
#> ps aux | grep zabbix

came up with no results. So it seems that there really no zabbix_server is running.

I have googled for almost 3 days now and found some obviously useful hints like expanding shared memory, or using strace to figure out the problems and so on.
But none of them helped. And since I'm running FreeBSD under amd64, strace is not available.

Here are some informations:

#> uname -a
FreeBSD monitoring.kits.loc 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255898: Thu Sep 26 22:50:31 UTC 2013     [email protected]:/usr/obj/usr/src/sys/GENERIC  amd64

#> zabbix_server -V
Zabbix server v2.2.1 (revision 40808) (09 December 2013)
Compilation time: Aug  4 2014 12:51:42

#> cat /tmp/zabbix_server.log
zabbix_server [64619]: cannot create Semaphore: [78] Function not implemented
zabbix_server [64619]: unable to create mutex for log file
[...]

For my understanding there should be something more inside the log files. But because the server seems not even to come up before ending immediately, either the mutex creation problem or maybe an access rights problem during startup phase could be causing that.

Valid options from zabbix_server.conf:

#>cat /usr/local/etc/zabbix22/zabbix_server.conf | grep -v -E -e '^(|#.*)$'
LogFile=/tmp/zabbix_server.log
DebugLevel=4
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=secret
ListenIP=xxx.xxx.xxx.xxx

How can I debug that problem?
Any ideas/suggestions?

B.T.W.: MySQL is accessible by mysql command. Full access rights for zabbix tables are set for zabbix@localhost and zabbix@external_IP

My problem is, that I can not see any log entries.

Who can help?

Does your FreeBSD have SELinux enabled? That could be part of the issue.

And another way I would try to start Zabbix server instead of using "service zabbix_server start" , would be this from the commandline:

/usr/local/sbin/zabbix_server -c /usr/local/etc/zabbix22/zabbix_server.conf

Of course, make the path match where your <binary path> -c <conf file path>

same result

Hi,

there is no SElinux installed in FreeBSD.
The Zabbix Server is running inside jail, so this might cause problems. But I have some other services like SMTP also running in jail (ezjail) and those work great. Jail config is almost the same except IP address.

I've already ran the command you mentioned earlier while testing. Result is the same.

As said, the problem is that there is really no log information at all.

Regards
Olaf
