Zabbix disables core dumps if compiled with encryption.....

@Astushi
Isaw documentation of zabbix it says "Zabbix disables core dumps if compiled with encryption and does not start if system does not allow disabling of core dumps". kindly tell me how to compile it with encryption.

It is not necessary to solve the problem that is occurring now.
Please restart the Zabbix server again and show the latest log of the Zabbix server.

# systemctl stop zabbix-server
# systemctl start zabbix-server

log file output

@Atsushi
the log file output:
75325:20171115:110632.139 [Z3001] connection to database 'zabbixdb' failed: [1045] Access denied for user 'zabbixuser'@'localhost' (using password: NO

You must specify the correct password for zabbix mysql user in /etc/zabbix/zabbix_server.conf.
Don't forget to remove the # before the line

### Option: DBPassword
# DBPassword=

This password was created with your zabbix DB, more info in the link
