Zabbix shows that ZBX is a red error solution get value from agent failed: cannot connect to [[127.0.0.1]:10050]

Hello, hello, friends, this is Changqing~

Everyone should have this problem after installing zabbix, that is, the ZBX font is red

Then display an error

get value from agent failed: cannot connect to [[127.0.0.1]:10050]

This probably means that the agent connection failed.

Solution

1. Let's first look at the firewall status

[root@m01 ~]# getenforce          #显示当前SELinux的应用模式
Disabled
[root@m01 ~]# systemctl status firewalld       #查看防火墙状态
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

2. Check whether the agent is started, check port 10050

netstat -lntup|grep 10050

It can be seen that there is no port 10050, indicating that the agent is not started, so we need to start the agent

[root@m01 ~]# systemctl start zabbix-agent.service    #启动agent服务
[root@m01 ~]# systemctl status zabbix-agent.service   #查看状态
● zabbix-agent.service - Zabbix Agent
   Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled)
