Zabbix Agent 5.0 install for centos

说明：
1、Agent版本建议跟服务端一致，不推荐高于Server端；
2、CentOS环境国内清华Mirror站点有镜像，因此直接在该Mirror站点取安装包

安装Zabbix Agent客户端

2、配置zabbix Agent配置文件：vim /etc/zabbix/zabbix_agent2.conf
Server=192.168.26.51 #定义Zabbix Server端地址
Hostname=zabbix-agent #定义Agent端的主机名


3、启动Zabbix Agent并加入自启动：systemctl restart zabbix-agent2 && systemctl enable zabbix-agent2

[root@zabbix-agent ~]# systemctl restart zabbix-agent2 && systemctl enable zabbix-agent2
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent2.service to /usr/lib/systemd/system/zabbix-agent2.service.
[root@zabbix-agent ~]# systemctl status zabbix-agent2
