可以使用下面的命令去验证你是否成功安装了Net-SNMP，如果你可以获取到正确的版本号，说明你已经成功安装了Net-SNMP
snmpget --version

chkconfig snmpd onsystemctl start snmp可通过如下命令检查snmpd是否启动
netstat -na | grep 161
或
ps aux | grep snmp
测试snmpd
可以用如下的几个命令获取系统开机时间，如果有正确的返回则说明snmp运行正常
snmpwalk -v 2c -c public localhost sysUpTime.0
配置python获取netsnmp
pip install client
pip install python3-netsnmp
