Please check selinux log

[root@localhost ~]# grep "SELinux is preventing" /var/log/messages
[root@localhost ~]# grep "denied" /var/log/audit/audit.log
[root@localhost ~]# sestatus
SELinux status: disabled
[root@localhost ~]#

Check what ipcs -us and ipcs -s show you. Perhaps, you just need to delete old semaphores manually (actually, make sure you let Zabbix terminate gracefully by not sending SIGKIL to it, use SIGTERM instead - this could be the reason for the buildup of old semaphores). Each Zabbix daemon needs just one semaphore set with less than 15 semaphores in it, so this shouldn't cause any issues with system limits.

hi 

before delete ipcrm but when retart zabbix-service  not start 

---------------------------------------------

root@localhost ~]# ipcs -us

------ Semaphore Status --------
used arrays = 6
allocated semaphores = 19

[root@localhost ~]# ipcs -s

------ Semaphore Arrays --------
key semid owner perms nsems
0x00000000 98304 zabbix 600 14
0x00000000 524289 apache 600 1

0x00000000 622596 apache 600 1
0x00000000 655365 apache 600 1

[root@localhost ~]#

Is the error message still the same in the log file?

yes . zabbix service not start

-------------------

cat /var/log/zabbix/zabbix_server.log

Are you sure these aren't old messages? Please do

tail -n 10 /var/log/zabbix/zabbix_server.log; systemctl restart zabbix_server; tail -n 10 /var/log/zabbix/zabbix_server.log

Maybe now Zabbix does not start for a different reason ("No such file or directory").

Erm, I guess the service is named zabbix-server, not zabbix_server (with a dash instead of underscore).

oh yes

Now you are checking the wrong log file. At least there are no new messages about semaphores.

tnks

how checking ? 

I think at this point you will progress faster if you address your questions to Zabbix community on IRC or forum. Check possible ways of getting help.

This place is a bug tracker and in your situation there is no indication of a bug in Zabbix.
