Centos7 下安装部署zabbix-agent客户端

Posted 2020-12-22 yangzp

一、环境介绍

官网地址：http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/

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

下载路径：

http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.5-1.el7.x86_64.rpm

http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-sender-3.4.5-1.el7.x86_64.rpm

将上传（xshell可用put上传）rpm软件包放入自己可找到的目录下，通过yum安装，如下：

 进入服务器，查看，两个安装包已上传

 

[root@Node3 zabbix3.4.5]# scp zabbix-agent-3.4.5-1.el7.x86_64.rpm zabbix-sender-3.4.5-1.el7.x86_64.rpm  root@node1:/usr/src/zabbix3.4.5/
root@node1‘s password: 
zabbix-agent-3.4.5-1.el7.x86_64.rpm               100%  359KB  29.9MB/s   00:00    
zabbix-sender-3.4.5-1.el7.x86_64.rpm              100%  260KB  33.2MB/s   00:00  

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

Complete!
[root@Node1 zabbix3.4.5]# id zabbix
uid=991(zabbix) gid=986(zabbix) groups=986(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
13:PidFile=/var/run/zabbix/zabbix_agentd.pid
32:LogFile=/var/log/zabbix/zabbix_agentd.log
43:LogFileSize=0
57:DebugLevel=3                         //日志级别，默认为3
97:Server=172.17.21.208                 //用于被动模式，数据获取
138:ServerActive=172.17.21.208          //用于主动模式，数据提交
149:Hostname=Node1.contoso.com          //必须与创建主机时的hostname一致
267:Include=/etc/zabbix/zabbix_agentd.d/*.conf  //包含子配置文件的路径
286: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 100
LISTEN     0      100    127.0.0.1:25                       *:*                  
LISTEN     0      128          *:10050                    *:*                  
LISTEN     0      100        ::1:25                      :::*                  
LISTEN     0      128         :::10050                   :::* 

 

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 10050 -k "system.hostname"      //获取主机名
Node1.contoso.com
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k "system.uptime"       //运行时间
125985
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k "vm.memory.size[total]"  //获取总内存，以下为4G
4143792128
[root@Node3 zabbix3.4.5]# 

６、在Web界面查看可用内存如下：
