zabbix-server not running

[Xyue]

Hi,

I have fresh install the zabbix server and database on the same server.

However, the service is not able to start.

Below is the error message

[zabbix@zabsrv system]$ sudo systemctl start zabbix-server.service
Job for zabbix-server.service failed because the control process exited with error code. See "systemctl status zabbix-server.service" and "journalctl -xe" for details.

Based on https://www.zabbix.com/forum/showthr...service+failed, seems like the pid file got wrong.

So i have done steps below :

1. check mysql socket in /etc/zabbix/zabbix-server.conf and have it modified from /tmp/sock to /var/lib/mysql/mysql.sock

2. Tried to chekc on the zabbix-server.pid on zabbix-server.conf and have modified it from /var/run/zabbix/zabbix_server.pid to /run/zabbix/zabbix_server.pid which is the same with

Any idea what cause the error ?

Thank you very much in advance

Hi Atsushi,

Can you give me some suggestion on the performance tuning for zabbix server ? I started to add host after the service is running. Soon, the server crash/not working due to lack of cache.

[file:strpool.c,line:53] zbx_mem_malloc(): out of memory (requested 50 bytes)
[file:strpool.c,line:53] zbx_mem_malloc(): please increase CacheSize configuration parameter

So, I modified the CacheSize from default to 1G and it was working as of now.

Would like to check with you what else i need to notice/modified on the server performance issue to prevent this things happen again?

Thank you very much.
