Now I want to share error for configuration shared memory of Zabbix server daemon. Many times you see not start zabbix server for shared memory problem. So I have to share this how to solve this problem.

At first check your zabbix server running status using below command.

$ sysctl -a |grep shmmax

Output below

kernel.shmmax = 3068709

Now increase shared memory for remove Zabbix service status no. Using below command. Remember it this is not permanent solution. When your server reboot then this settings not working.

$ sysctl -w kernel.shmmax=536870912
$ sysctl -a |grep shmmax

This is permanent solution shared memory for zabbix server

$ vi /etc/sysctl.conf

Insert below value into this file

kernel.shmmax=536870912

Save for press. Esc :wq then press Enter.
