Server won't start

[Nestor]

I'm trying to set up a Zabbix server in a test environment.

I've followed the guide on the Zabbix site https://www.zabbix.com/download but for some reason the server itself won't fire up.

Log file:

Server config file (Yes, I even used the default password "password" in this test case)

DBName=zabbix

### Option: DBSchema
# Schema name. Used for IBM DB2 and PostgreSQL.
#
# Mandatory: no
# Default:
# DBSchema=

### Option: DBUser
# Database user. Ignored for SQLite.
#
# Mandatory: no
# Default:
# DBUser=

DBUser=zabbix

### Option: DBPassword
# Database password. Ignored for SQLite.
# Comment this line if no password is used.
#
# Mandatory: no
# Default:

DBPassword=password

Any ideas?

Please carefully look at the log file.
An error has occurred that sockets can not be created due to insufficient permissions.

 22324:20180523:155440.976 cannot start alert manager service: Cannot bind socket to "/var/run/zabbix/zabbix_server_alerter.sock": [13] Permission denied.
 22325:20180523:155440.978 cannot start preprocessing service: Cannot bind socket to "/var/run/zabbix/zabbix_server_preprocessing.sock": [13] Permission denied.

Check the permissions of the relevant directory.
If you have enabled SELinux, please set policies properly.

So I disabled SElinux and now everything is running (that's what the logs tell me).

I just don't get any login page or anything when I surf to the URL of the machine.


What am I missing?

[Atsushi]

Did you install the Web frontend packages?
For packages for RHEL, zabbix-web and zabbix-web-mysql packages.

Have you set up timezone in /etc/httpd/conf.d/zabbix.conf file and started httpd?

If you are using Firewall, did you set permission to access web server such as HTTP?

Hi everybody.

I dont know why, but "maggicaly" the follow command works:

grep AVC /var/log/audit/audit.log* | audit2allow -M systemd-allow; semodule -i systemd-allow.pp

The original reference came from : http://microdevsys.com/wp/zabbix-can...lready-in-use/

I disabled selinux, rebooted the CentOS host. This fixed the problem.

Thanks Atsushi it really work! I disable selinux, reboot, set firewall permission and it fixed the problem
