After installing and configuring zabbix_agentd, Get value error: cannot connect to [[192.168.238.139]:10050]: [113] No route to host appears on the web page, and the client host cannot be monitored
Solution:
First, ping the client's IP on the server side to see if it can ping, if it can ping, it is a firewall problem, just close the client firewall!
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #Prohibit firewall from starting
systemctl status firewalld.service #View firewall status
