Install Zabbix on CentOS 7

Just finished setting up a Zabbix vm following the guide =).

I need to finish the guide and figure out the SELinux issues.

Romo

@JaredBusch It's true, totally forgot we used setenforce 0 in the guide, so I am not actually finished just yet then =P

Romo

Using setsebool -P httpd_can_connect_zabbix=1 everything appears to be working.

So I've got this installed, I've got the agent installed on my windows box, but just cant get any data to send.

I can telnet from Zabbix to windows box on 10050 but not the other way around.

Would that be my issue or no?

Thanks

Romo

@Sparkum Agents listen on port 10050 and apparently the server listens on port 10051;

so runnning the following on the server:
firewall-cmd --permanent --add-port=10051/tcp
systemctl restart firewalld

Should get the agents connecting properly to the server, I haven't tested it because I have not set any agents to monitor yet in the lab, but from reading the documentation is should work.

@Romo
Hmm still no, silly Z doesnt wanna turn green.

I assume if I added a linux box I would be up in second.

Romo

@Sparkum Can you post your dashboard please =). Did you activate the host, Configuration>hosts>yourhost>enable?

Sparkum

@Romo

Sorry just a screenshot of my dashboard?

Yep, host is enabled.

I'm getting stats from the Zabbix agent, just now windows agent.

Romo

@Sparkum So its working now, right?

I'm going to try this tonight.

@Romo

Zabbix is working, zabbix agent on the server is working, just cant get any communication from windows agent, so not sure if you have any experience with the windows agent or not.

Have you checked the windows firewall? There's Zabbix is usually blocked by it.

Also, check the zabbix_agentd.conf file on your Windows box and make sure the Server and ServerActive IP addresses are set to your Zabbix Server's ip?

@dafyre

Both are set to 192.168.1.167 (which is internal IP of zabbix server)

And I created inbound and outbound rules for 10050 and 10051

Got the 10050 and 10051 open on your Zabbix server?

Sparkum

@dafyre

Well I did this

firewall-cmd --permanent --add-port=10051/tcp
firewall-cmd --permanent --add-port=10050/tcp

So I assume yes?

How exactly would I check, sorry

Did you

firewall-cmd --reload ?

Edit: That's a good question... I'm not sure about how to do that with firewalld.

Sparkum

@dafyre

Yep I've reloaded and rebooted.
