using proxy in clustered environment

[hakanozanlagan]

I have a Zabbix cluster server with 2 nodes. I need to set up a Zabbix proxy for this environment. However, Zabbix proxy does not allow the use of two IP addresses in the "Server=" definition and we can only use one IP address.
I tried to do it with a load balancer. However, Zabbix cluster is running simultaneously with port 1051 open on both nodes and there is no way for the load balancer to understand which node is active.
Is there a way to use a Zabbix proxy in a clustered environment?

Hi,

What if you use 2 FQDN's with the same name but with different IP address, one for each of your nodes, and use that as the Server address in your proxy configuration ?

Yes. You can have 2 IP addresses in the proxy conf. The separator is a semi colon.
Server=address colon port;address2 colon port of Zabbix server

I tried below configs Proxy server is failed to start. it is running in agent conf but proxy is not supporting multiple server config.

Server=192.168.88.100:10051,192.168.88.101:10051
or
Server=192.168.88.100,192.168.88.101

I solved problem with workaround.

# add cluster status in "/usr/share/zabbix/clusterstatus.txt" file on both nodes via cron. (0 or 1)
* * * * * zabbix_server -R ha_status |grep -c "Last Access" > /usr/share/zabbix/clusterstatus.txt

#check server status and take action on proxy side.
* * * * * /etc/zabbix/scripts/proxycheck.sh


cat proxycheck.sh
#!/bin/bash

proxyActiveIp=$(grep "^Server=" /etc/zabbix/zabbix_proxy.conf |awk -F"=" '{print $2}')
zbxsrv01status=$(curl -sk https://zbxsrv01.eduenv.com/clusterstatus.txt)
zbxsrv02status=$(curl -sk https://zbxsrv02.eduenv.com/clusterstatus.txt)


#check for nodes (192.168.88.100,192.168.88.101)
if [ $zbxsrv01status == 1 ] && [ $proxyActiveIp != "192.168.88.100" ]
then
sed -i 's/^Server=192\.168\.88\.101$/Server=192.168.88.100/' /etc/zabbix/zabbix_proxy.conf
systemctl restart zabbix-proxy

elif [ $zbxsrv02status == 1 ] && [ $proxyActiveIp != "192.168.88.101" ]
then
sed -i 's/^Server=192\.168\.88\.100$/Server=192.168.88.101/' /etc/zabbix/zabbix_proxy.conf
systemctl restart zabbix-proxy
fi

The separator in the proxy config needs to be a semi colon.
Server=192.168.88.100:10051;192.168.88.101:10051
or
Server=192.168.88.100;192.168.88.101

I didn't pay attention to the comment and just looked at the line below and saw the semicolon as a comma. It worked when I used a semicolon, thanks
Server=address colon port;address2 colon port of Zabbix server
