1. 直接安装，无法安装

[root@JumpServer ~]# yum install -y zabbix-agent2
OS                                                                                                                                     101 kB/s | 3.8 kB     00:00

No match for argument: zabbix-agent2
Error: Unable to find a match: zabbix-agent2

2. 因为没有仓库

[root@JumpServer ~]# ls /etc/yum.repos.d/
openEuler.repo

3. 安装zabbix仓库

[root@JumpServer ~]# rpm -Uvh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-4.el8.noarch.rpm

4. 再看看仓库列表

[root@JumpServer ~]# ls /etc/yum.repos.d/
openEuler.repo  zabbix-agent2-plugins.repo  zabbix.repo

5. 好了，可以安装了。

[root@JumpServer ~]# yum install -y zabbix-agent2

6. 设置开机自动启动

[root@JumpServer ~]# systemctl enable zabbix-agent2.service 
Created symlink /etc/systemd/system/multi-user.target.wants/zabbix-agent2.service → /usr/lib/systemd/system/zabbix-agent2.service.

7. 修改zabbix-agent2配置文件

[root@JumpServer ~]# cat /etc/zabbix/zabbix_agent2.conf | grep -Ev '^$|^#'
PidFile=/run/zabbix/zabbix_agent2.pid
LogFile=/var/log/zabbix/zabbix_agent2.log
LogFileSize=0
Server=172.16.30.120
ServerActive=172.16.30.120
Hostname=JumpServer
Include=/etc/zabbix/zabbix_agent2.d/*.conf
ControlSocket=/tmp/agent.sock
Include=./zabbix_agent2.d/plugins.d/*.conf

就改这三个值
Server=172.16.30.120
ServerActive=172.16.30.120
Hostname=JumpServer

8. 重启zabbix-agent2服务并查看其状态

[root@JumpServer ~]# systemctl restart zabbix-agent2.service 
[root@JumpServer ~]# systemctl status zabbix-agent2.service 
● zabbix-agent2.service - Zabbix Agent 2
     Loaded: loaded (/usr/lib/systemd/system/zabbix-agent2.service; enabled; vendor preset: disabled)
     Active: active (running) since Thu 2022-12-08 22:38:20 CST; 55s ago

             └─322754 /usr/sbin/zabbix_agent2 -c /etc/zabbix/zabbix_agent2.conf

[root@JumpServer ~]# ps -ef | grep zabbix

9. 设置防火墙放行10050端口

[root@JumpServer ~]# firewall-cmd --permanent --add-port=10050/tcp
success  
[root@JumpServer ~]# firewall-cmd --reload 
success

10. 成功。
