1.测试环境
在VMware上安装两台Centos7系统，一台作为SNMP NMS(IP:192.168.10.131)，一台作为：SNMP Agent(IP:192.168.10.245)，分别在其系统上安装snmp服务
2.基础环境配置
为了防止防火墙及selinux等的影响，需关闭防火墙及selinux等，具体参考：
Linux常规基础配置_linux基础配置-CSDN博客
3.安装snmp
yum源配置，具体参考：
Linux常规基础配置_linux基础配置-CSDN博客
3.1.SNMP NMS端安装snmp

4.配置snmp
4.1.SNMP NMS端安装snmp
1.进入/etc/snmp目录
2.编辑snmpd.conf文件，并保存
#启用社区信息，只允许本主机访问该节点
com2sec notConfigUser localhost public
com2sec notConfigUser 192.168.10.131 public
#把用户加入安全组
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
#可以查看.1下所有OID的对象信息
view all included .1 80
#允许可读权限
access notConfigGroup "" any noauth exact all none none
3.启动snmp
命令：
systemctl start snmpd
[root@logstash snmp]# systemctl start snmpd
[root@logstash snmp]# systemctl status snmpd
