1、CentOS7下配置snmpd服务
#安装snmp服务 yum install net-snmp net-snmp-utils #设置开机自启动 systemctl enable snmpd.service #启动snmp服务 systemctl start snmpd.service #查看snmp端口161是否存在 netstat -anp | grep 161 #查看snmp状态 systemctl status snmpd.service #snmp v2版本信息获取查看 snmpwalk -v 2c -c public 192.168.1.171
操作过程：
2、使用net-snmp-create-v3-user进行snmp v3配置
1)先停止snmpd服务
systemctl stop snmpd.service
2)使用net-snmp-create-v3-user命令进行snmp v3配置用户名和密码：
[root@k8s-node1 ~]# net-snmp-create-v3-user Enter a SNMPv3 user name to create: snmpuser Enter authentication pass-phrase: 1111qqqq Enter encryption pass-phrase: [press return to reuse the authentication pass-phrase] 1111qqqq adding the following line to /var/lib/net-snmp/snmpd.conf: createUser snmpuser MD5 "1111qqqq" DES 1111qqqq adding the following line to /etc/snmp/snmpd.conf: rwuser snmpuser [root@k8s-node1 ~]#
按上面的输出提示可以查看如下两个配置中新增行：
tail -n 5 /var/lib/net-snmp/snmpd.conf tail -n 5 /etc/snmp/snmpd.conf
3)启动snmpd服务
systemctl restart snmpd.service
4)snmpwalk命令验证
或者用其它snmp客户端工具测试
