一、安装zabbix-agent3.2版本的yum源文件

[root@localhost home]# rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

二、修改zabbix的repo文件里的yum源地址为阿里云镜像地址

[root@localhost home]# vim /etc/yum.repos.d/zabbix.repo 

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://mirrors.aliyun.com/zabbix/zabbix/3.2/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://mirrors.aliyun.com/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

三、yum安装zabbix-agent

[root@localhost home]# yum install zabbix-agent

四、修改zabbix-agent的配置文件

[root@localhost zabbix]# vim /etc/zabbix/zabbix_agentd.conf 

Server=172.28.18.75
ServerActive=172.28.18.75
Hostname=172.28.5.124

五、修改zabbix-agent服务配置为开机自启动

[root@localhost zabbix]# systemctl list-unit-files|grep zabbix
zabbix-agent.service                          disabled
[root@localhost zabbix]# 

当前默认是禁止自启动的，我们修改为开机自启动

[root@localhost zabbix]# 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.

再次查看

[root@localhost zabbix]# systemctl is-enabled zabbix-agent.service
enabled

六、启动zabbix-agent服务

[root@localhost zabbix]# systemctl start zabbix-agent.service

查看

[root@localhost zabbix]# systemctl status zabbix-agent.service
● zabbix-agent.service - Zabbix Agent
   Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; enabled; vendor preset: disabled)
   Active: active (running) since 五 2021-07-02 17:20:36 CST; 7s ago

           ├─14804 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection]
           └─14805 /usr/sbin/zabbix_agentd: active checks #1 [idle 1 sec]

7月 02 17:20:36 localhost.localdomain systemd[1]: Starting Zabbix Agent...
7月 02 17:20:36 localhost.localdomain systemd[1]: Started Zabbix Agent.
[root@localhost zabbix]# 

启动成功，在zabbix server上执行

[root@zabbix_server home]# zabbix_get -s 172.28.5.124 -p 10050 -k 'system.uname'
Linux localhost.localdomain 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64
[root@zabbix_server home]# 

成功获取服务器信息。
