zabbix-server can't start

[freshmanlemon]

Hi.

I have the next problem:

OS: fedora 15
DB: mysql
Zabbix: 1.8.5

OS is fresh, installed just for zabbix. when i try to start zabbix server, i see:

[root@yfn-srv-f /]# service zabbix-server stop
Stopping zabbix-server (via systemctl):                    [  OK  ]
[root@yfn-srv-f /]# service zabbix-server start
Starting zabbix-server (via systemctl):                    [  OK  ]
[root@yfn-srv-f /]#

But in zabbix_server.log:
Debug level 4 (max)

6602:20110815:021542.972 Starting Zabbix Server. Zabbix 1.8.5 (revision 19050).

Cannot allocate shared memory of size 8421263 [Permission denied]

In mysql:
I have installed phpmyadmin, so there i set all privileges to user 'zabbix' to db 'zabbix.*'

sory, i'm not good in mysql and dont know how to look it in console.


So, i realy cant understed where is a trouble (( which kind of permission is denied and where.

Please, help.

you must change the shmax in the kernel-config..

look at this:

I have read many forums, changing of SHMMAX solve problem when in log the next
Can't allocate shared memory of size 29361092 [Cannot allocate memory]
But in my case:
Cannot allocate shared memory of size 8421263 [Permission denied]


The current value of shmmax in system is 33554432
it is bigger then needed to zabbix I think.

Anyway I have chenged it

[root@yfn-srv-f proc]# cat /proc/sys/kernel/shmmax
268435456

the same result

1721:20110815:131102.627 Cannot allocate shared memory of size 8421263 [Permission denied]
  1721:20110815:131102.627 cannot allocate shared memory for history cache

I realy think i have a problem with privileges

ok.. ehm.. i think its a problem of SElinux.. disable that or reconfigure this..

[freshmanlemon]

Yuuuhuuu! ))

Shad0w, Thank you so much!

Realy, it's SELinux.
Right now I just disabeled it and zabbix-server started well! The next step is RTFM of SELinux.

Thanks a lot one more time!
