3. 修改zabbix agent配置文件

[root@centos7 ~]#vim /etc/zabbix/zabbix_agentd.conf
Server=10.0.0.17  #指向当前zabbix server
ListenPort=10050  #监听端口
ListenIP=0.0.0.0  #监听IP
StartAgents=5  #被动状态时，默认启动的实例（进程数），0为不监听任何端口
Hostname=10.0.0.7  #区分大小写且在zabbix server唯一的值

[root@centos7 ~]#grep "^[a-Z]" /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=10.0.0.17
ListenPort=10050
ListenIP=0.0.0.0
StartAgents=5
ServerActive=127.0.0.1
Hostname=10.0.0.7
Include=/etc/zabbix/zabbix_agentd.d/*.conf

[root@centos7 ~]#systemctl restart zabbix-agent.service
[root@centos7 ~]#systemctl enable zabbix-agent.service
[root@centos7 ~]#systemctl status zabbix-agent.service

5. zabbix web界面添加被监控主机

点击【配置-主机-创建主机】

#【ZBX】绿色，表示主机可用，监控指标检查已成功，zabbix server对zabbix agent有权限进行数据采集并且当前通信正常

经过一段时间的数据采集后，就可以看到数据了

6. 在zabbix server主机上安装Zabbix get命令行工具

#Zabbix get是一个命令行应用，它可以用于与Zabbix agent进行通信，并从Zabbix agent那里获取所需的信息。
该应用通常被用于Zabbix agent故障排错。

[root@centos7 ~]#yum list all |grep zabbix-get
zabbix-get.x86_64                          5.0.24-1.el7           zabbix

[root@centos7 ~]#yum -y install zabbix-get.x86_64

[root@centos7 ~]#/bin/zabbix_get -s 10.0.0.7 -p 10050 -k "agent.ping"
