三、修改SNMP相关配置文件
[root@IT-01 ~]# grep -Ev '^#|^$' /etc/snmp/snmpd.conf
com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
view systemview included .1
access notConfigGroup "" any noauth exact systemview none none
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
dontLogTCPWrappersConnects yes
四、重启snmp服务
[root@IT-01 ~]# systemctl start snmpd
五、测试收集信息
[root@IT-01 ~]# snmpwalk -v 2c -c public 127.0.0.1 sysname
SNMPv2-MIB::sysName.0 = STRING: IT-01
六、WEB配置
七、检查SNMP是否添加成功
