上一篇博客我们分享了如何基于yum的方式部署zabbix 4.0.0版本。接下来，我们就监控其他主机的item项吧。
一.在需要监控的主机上部署zabbix-agent服务
1>.安装zabbix-agent
[root@node102 ~]# rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

二.在zabbix Server添加对node102.yinzhengjie.org.cn节点的监控
1>.如下图所示，点击创建一个主机组
2>.输入要创建的组名，名称你可以自定义
3>.组名添加完成
4>.如下图所示，点击创建主机
5>.配置被监控主机的基本信息（注意，带有*是必须要填写的！必须至少存在一个接口。）
6>.连接模板
7>.点击添加按钮
8>.添加完成
9>.等待30s左右，Zabbix Server就会监控到Zabbix agent的item了，监控成功，我们会看到一个绿灯
10>.查看监控的图像
