03: zabbix報錯：active check configuration update from....started to fail

一臺新機器添加zabbix_agentd後，配置文件都是對的，啓動後發現報錯：

root@xxxx:~# tail -f /var/log/zabbix/zabbix_agentd.log
14684:20190904:091617.523 Starting Zabbix Agent [SGH1VBOX09]. Zabbix 2.2.9 (revision 52686).

首先ping zabbix server 的ip發現是能夠ping通的， 以後去zabbix server端也能ping通 agentd 端IP。

可是在server端用zabbix get 命令不能獲取到數據。

------------------------------------------------------------------------------------

其實log裏面已經很明確的告訴咱們，是不能鏈接到10051端口。 因此使用telnet 命令探測一下端口是否能通

root@xxx:~# telnet 1xx.xx.xx.xx 10051
Trying 1xx.xx.xx.xx...
^C
root@xxx:~# telnet 1xx.xx.xx.xx 80
Trying 1xx.xx.xx.xx...
^C
發現端口根本不通，問題找到就好解決了，首先確認agentd端有沒有配置防火牆規則，其次再去看server有沒有配置規則。相應的找安所有門人員開通一下就好。
