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 Retrieving https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm warning: /var/tmp/rpm-tmp.pYEOk0: Header V4 RSA/SHA512 Signature, key ID a14fe591: NOKEY Preparing... ################################# [100%] Updating / installing... 1:zabbix-release-4.0-1.el7 ################################# [100%] [root@node102 ~]# [root@node102 ~]#

2>.配置zabbix-agent
[root@node102 ~]# cat /etc/hosts | grep yinzhengjie 172.30.1.101 node101.yinzhengjie.org.cn 172.30.1.102 node102.yinzhengjie.org.cn 172.30.1.103 node103.yinzhengjie.org.cn [root@node102 ~]# [root@node102 ~]# hostname node102.yinzhengjie.org.cn [root@node102 ~]# [root@node102 ~]# hostname -i 172.30.1.102 [root@node102 ~]# [root@node102 ~]# cat /etc/hosts | grep yinzhengjie 172.30.1.101 node101.yinzhengjie.org.cn 172.30.1.102 node102.yinzhengjie.org.cn 172.30.1.103 node103.yinzhengjie.org.cn [root@node102 ~]# [root@node102 ~]# [root@node102 ~]# grep Server /etc/zabbix/zabbix_agentd.conf | grep -v ^# Server=127.0.0.1 ServerActive=127.0.0.1 [root@node102 ~]# [root@node102 ~]# [root@node102 ~]# sed -i 's#Server=127.0.0.1#Server=node101.yinzhengjie.org.cn#' /etc/zabbix/zabbix_agentd.conf [root@node102 ~]# [root@node102 ~]# sed -i 's#ServerActive=127.0.0.1#ServerActive=node101.yinzhengjie.org.cn#' /etc/zabbix/zabbix_agentd.conf [root@node102 ~]# [root@node102 ~]# [root@node102 ~]# grep Server /etc/zabbix/zabbix_agentd.conf | grep -v ^# Server=node101.yinzhengjie.org.cn ServerActive=node101.yinzhengjie.org.cn [root@node102 ~]#
3>.启动zabbix-agent
[root@node102 ~]# systemctl enable zabbix-agent Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service. [root@node102 ~]# [root@node102 ~]# systemctl start zabbix-agent [root@node102 ~]# [root@node102 ~]# systemctl status zabbix-agent ● zabbix-agent.service - Zabbix Agent Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2019-02-15 04:53:25 PST; 3s ago Process: 2725 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS) Main PID: 2727 (zabbix_agentd) CGroup: /system.slice/zabbix-agent.service ├─2727 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf ├─2728 /usr/sbin/zabbix_agentd: collector [idle 1 sec] ├─2729 /usr/sbin/zabbix_agentd: listener #1 [waiting for connection] ├─2730 /usr/sbin/zabbix_agentd: listener #2 [waiting for connection] ├─2731 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection] └─2732 /usr/sbin/zabbix_agentd: active checks #1 [idle 1 sec] Feb 15 04:53:25 node102.yinzhengjie.org.cn systemd[1]: Starting Zabbix Agent...

4>.测试zabbix-agent服务是否正常
[root@node101 ~]# hostname node101.yinzhengjie.org.cn [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# hostname -i 172.30.1.101 [root@node101 ~]# [root@node101 ~]# yum -y install telnet Loaded plugins: fastestmirror base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 mysql-connectors-community | 2.5 kB 00:00:00 mysql-tools-community | 2.5 kB 00:00:00 mysql56-community | 2.5 kB 00:00:00 updates | 3.4 kB 00:00:00 zabbix | 2.9 kB 00:00:00 zabbix-non-supported | 951 B 00:00:00 Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: ftp.sjtu.edu.cn * updates: mirrors.nwsuaf.edu.cn Resolving Dependencies --> Running transaction check ---> Package telnet.x86_64 1:0.17-64.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================= Package Arch Version Repository Size ======================================================================================================================================= Installing: telnet x86_64 1:0.17-64.el7 base 64 k Transaction Summary ======================================================================================================================================= Install 1 Package Total download size: 64 k Installed size: 113 k Downloading packages: telnet-0.17-64.el7.x86_64.rpm | 64 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : 1:telnet-0.17-64.el7.x86_64 1/1 Verifying : 1:telnet-0.17-64.el7.x86_64 1/1 Installed: telnet.x86_64 1:0.17-64.el7 Complete! [root@node101 ~]#
[root@node101 ~]# telnet node102.yinzhengjie.org.cn 10050 Trying 172.30.1.102... Connected to node102.yinzhengjie.org.cn. Escape character is '^]'. #很显然，服务时正常的 Connection closed by foreign host. [root@node101 ~]#
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
