Problem with The first start to ZABBIX Server

[ninoo]

Hello boy
I'm a new user of zabbix .I create a debian server and install zabbix . The first start Zabbix in the GUI I read Zabbix server not running .I go to the /etc/zabbix/zabbix_server.conf and enable ListenPort=10051 and enable DBPassword=.............
Go to the shell and systemctl restart zabbix-server zabbix-agent apache2 and systemctl enable zabbix-server zabbix-agent apache2
reboot the machine

Now the server I read

No	localhost:10051

but this error .

The file log is :

Please check your /var/www/zabbix/conf/zabbix.conf.php if it contains $ZBX_SERVER and $ZBX_SERVER_PORT

[mwildam]

It looks like the web interface is not able to get the server status. Also check the agent log - although it seems to recognize the agent being there (because of the green ZBX).
I assume, you have the web interface running on the same host as the zabbix server (so it cannot be a firewall issue).

Hi friend, try this...

First at all, check the log file on /var/log/zabbix_server.log to find any error...

Your firewalld have permissions? Maybe u can disable a little to do some test's... The same with SELINUX... Need stay on permissive or disabled...

User rights to create database...

Check your log file and show us what u have...
