Cenos7 安装配置Zabbix-Agent客户端

1.yum -y install zabbix-agent;
2.安装完成后配置文件一般在 /etc/zabbix/zabbix_agentd.conf，打开把里面内容全部清空然后加入PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log #错误日志
LogFileSize=0
ListenPort=10050 #启动监听端口
StartAgents=3 #被动模式下选择，主动模式则为0
ListenIP=0.0.0.0 #监听所有IP
Server=10.27.146.250 #被动模式下必填，将zabbix-server端的ip填入
#ServerActive=10.27.146.250 #主动模式下填写
Hostname=Api1Bearead #本机的hostname，此值必须与zabbix的网页上创建的主机名一致即可
Include=/etc/zabbix/zabbix_agentd.d/3.service zabbix-agent restart  #启动客户端
4.在zabbix的网页端创建一个新的项目





请确保这里的主机名和配置的主机名一致，这里的IP填写的是安装客户端服务器的IP地址
