配置代理端

代理端就是被控服務器,如果服務器也需要被自己監控也需要安裝abbix-agent

#關閉防火墻并設定開機自關
systemctl stop firewalld.service 
systemctl disable firewalld.service 

#安裝yum源
rpm -ivh http://repo.zabbix.com/zabbix/3.5/rhel/7/x86_64/zabbix-release-3.5-1.el7.noarch.rpm

#安裝zabbix-agent
yum install -y zabbix-agent

#修改配置文件
grep -n '^'[a-Z] /etc/zabbix/zabbix_agentd.conf

13:PidFile=/var/run/zabbix/zabbix_agentd.pid
32:LogFile=/var/log/zabbix/zabbix_agentd.log

vim /etc/zabbix/zabbix_agentd.conf

#139行，指向監控服務器IP
Hostname=czt                    
#150行,可自行定義主機名

#啟動服務
systemctl enable zabbix-agent.service
systemctl start zabbix-agent.service

#查看服務監聽端口
netstat -anpt | grep zabbix

在WEB平臺上做增加被控主機,以便監控端識別

訪問http://192.168.142.123/zabbix/配置-主機-創建主機：

• 配置下的主機選項，點擊創建主機
  

• 在主機配置界面填入相應內容，然后點擊模板
  

• 在模板中選擇HTTP和SSH的模板鏈接，點擊提示器中的添加，然后再點擊添加
  

• 新添加的監控項
  

謝謝閱讀!
