兰生幽谷，不为莫服而不芳；
君子行义，不为莫知而止休。
应用拓扑图
3.0准备工作
所有Linux服务器上（服务器和Agent端）安装下列工具
| yum -y install net-snmp net-snmp-utils |
保证所有的HCL网络设备和服务器相互间能够连通。
为了方便辨识，服务器对HCL的一台路由器、一台Centos7.9服务器进行管理：
| 角色 | ip | 操作系统 | |
| SNMP 服务器 | 192.168.56.220 | OpenEuler22.03sp4 | |
| SNMP agent | 192.168.56.22 | CentOS7.9 | |
| R1路由器 | 192.168.56.11 | H3C Comware |
3.1 读取参数
华三网络设备就按缺省配置。其他snmp agent端需要配置一下。红色部分是需要添加或更改的：
| [root@cts-zbxagt ~]# vi /etc/snmp/snmpd.conf …… rwcommunity private 192.168.56.0/24 //定义读写community及网段 rwcommunity public 192.168.56.0/24 com2sec writeAccess 192.168.56.0/24 private com2sec writeAccess 192.168.56.0/24 public rwuser snmpuser auth -V 2c //不同版本应用 …… #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 …… ############################################################################### # System contact information # It is also possible to set the sysContact and sysLocation system # variables through the snmpd.conf file: syslocation Building No.7 7907 //定义设备所在位置 syscontact Wu Zhengzhong <1531036898@qq.com> //定义设备管理联系方式 …… |
保存后，重启snmp:systemctl restart snmpd
下面我们将按照MIB-2结构逐一读取HCL网络设备和Linux服务器的相关信息。
在上一章，我们已经在HCL里面对路由器R1进行了SNMP-AGENT设置，下面我们将按照MIB-2的体系，读取HCL网络设备R1和Linux服务器信息
3.1.1 读取Mib-2 1系统system功能组数据
1）读取HCL路由器
前面服务器上已经安装snmp工具，可以直接在服务器上读取、管理网络设备的相关参数。

二）更改Linux服务器名称
确保在snmp客户端（192.168.56.22）上配置可写
| #修改配置文件 …… rwcommunity private com2sec writeAccess 192.168.56.0/24 private rwuser snmpuser auth -V 2c …… |
重启systemctl restart snmpd
在服务器端（192.168.56.220）更改agent系统名称
| [root@zbx624oe2203 ~]# snmpset -v 1 -c private 192.168.56.22 .1.3.6.1.2.1.1.5.0 s WuSnmpAgent SNMPv2-MIB::sysName.0 = STRING: WuSnmpAgent |
