Installing 3.2 on RHEL6.8

[jotarokujo]

I'm trying to install zannix on Redhat 6.8.

Everything went smoothly, until I got to the frontend installation.

First of all yum didn't install the /etc/httpd/conf.d/zabbix.conf file. I copied it from here.

However when I go to the URL on my browser, it gives me this error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Any clues what's wrong? Something in the php config file?

Hi, yes, you have one mistake in that cfg.

I assume that you are using Apache2.2 which, so you need to comment the line in your file:

# Require all granted in your zabbix.conf

Also, be sure that your server have php5.4 or newer.

Thank you for your reply.

I have made this change but I still cannot load the page. Now it just says:

HTTP ERROR 500

Is this because I only have php5.3?

# rpm -qa |grep http

I managed to configure the frontend. Now I'm trying to config the server to auto register active agents as explained in this page.

I also added the zabbix server (ibm056) to the Server= line, since it was giving me an error. Now I don't see any error in the log files (both zabbix_agentd.log and zabbix_server.log), however the client host is not added to zabbix.

How do I debug this problem?

I have attached my zabbix_agentd.conf file.

Hi, that's cool that you've managed the frontend thing. Gratz!

So, about your configuration of the host:

• Are you sure that your server is reachable via hostname ? For the first time it is better to use IP
• Next big thing is your hostname of host where agent is running - This is mandatory to assign unique Hostname if you want to get active checks or agent auto-registration.
• And, finally, you need to create Auto-registration action in Configuration -> Action [Auto Registration] -> Create action and configure conditions and operations

About the Debugging , actually, you can increase the loglevel adding the line DebugLevel=4

Alexey!

• I changed the zabbix server hostname to its IP in zabbixagentd.conf
• I already have unique hostnames for all my servers
• I have created the action seen in the attached image. Is it correct?

I increased the debuglog, and here's what I get in agent host:

I still don't see any new hosts added. What am I doing wrong?
