After the linux server deploys node_exporter
Start the node_exporter service, everything is normal, and the log does not report an error. The access address: http://ip:9100, but it cannot be accessed
as shown in the picture
Visit the Prometheus platform http://ip:9090, state display down
The configuration of the other two servers is normal
Suddenly thought of the firewall problem
It's too late to say it, check the firewall status immediately
Sure enough, it's not closed. Compared with other servers, it is closed.
Then close the firewall systemctl stop firewalld.service, check systemctl status firewalld.service again, it is closed
Visit the node_exporter service and Prometheus again, it's normal!
easy~
