Zabbix Agent for Linux部署（四）

一、环境介绍

二、代理安装

1、将代理程序拷贝至Node1服务器的/usr/src/zabbix3.4.5/目录下

[root@Node3 zabbix3.4.5]# scp zabbix-agent-3.4.-.el7.x86_64.rpm zabbix-sender-3.4.-.el7.x86_64.rpm  root@node1:/usr/src/zabbix3.4.5/
root@node1's password:
zabbix-agent-3.4.-.el7.x86_64.rpm               %  359KB  .9MB/s   :
zabbix-sender-3.4.-.el7.x86_64.rpm              %  260KB  .2MB/s   :  

2、代理通过yum的方式来安装

[root@Node1 zabbix3.4.5]# yum install -y *.rpm ./      //通过yum方式安装当前目录下的rpm包
Loaded plugins: fastestmirror, langpacks

Complete!
[root@Node1 zabbix3.4.5]# id zabbix
uid=(zabbix) gid=(zabbix) groups=(zabbix)
[root@Node1 zabbix3.4.5]# 

3、修改/etc/zabbix/zabbix_agentd.conf配置文件

[root@Node1 ~]# vim /etc/zabbix/zabbix_agentd.conf
[root@Node1 ~]# grep -n "^[a-Z]" /etc/zabbix/zabbix_agentd.conf
:PidFile=/var/run/zabbix/zabbix_agentd.pid
:LogFile=/var/log/zabbix/zabbix_agentd.log
:LogFileSize=
:DebugLevel=3                         //日志级别，默认为3
:Server=172.17.21.208                 //用于被动模式，数据获取
:ServerActive=172.17.21.208          //用于主动模式，数据提交
:Hostname=Node1.contoso.com          //必须与创建主机时的hostname一致
:Include=/etc/zabbix/zabbix_agentd.d/*.conf  //包含子配置文件的路径
:UnsafeUserParameters=1                    //允许所有字符的参数传递给用户定义的参数,默认为0，即没有启用

4、启动zabbix_agent服务器，并设置开机自启动

[root@Node1 ~]# systemctl start zabbix-agent.service
[root@Node1 ~]# systemctl enable zabbix-agent.service
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
[root@Node1 ~]# ss -tnl | grep
LISTEN               127.0.0.1:                       *:*
LISTEN                     *:                    *:*
LISTEN                   :::                      :::*
LISTEN                    :::                   :::* 

三、Zabbix Server上添加主机

1、点击Configuration-->Hosts-->Greate host,然后点击Add，进行添加即可

2、点击添加之后，进入Configuration-->Hosts界面进行模板关联

3、选择 Node1节点这后，点击Templates,选择所需要的模板进行关联，然后点击Add,然后Update即可

4、然后看到以下界面，说明模板已经关联，发现ZBX为绿色，代表正常：

5、在zabbix服务器获取相关参数值：

[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p  -k "system.hostname"      //获取主机名
Node1.contoso.com
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p  -k "system.uptime"       //运行时间

[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p  -k "vm.memory.size[total]"  //获取总内存，以下为4G

[root@Node3 zabbix3.4.5]# 

６、在Web界面查看可用内存如下：
