Python 开发环境搭建(5)：SNMP

使用的系统为Redhat 7.6 的64位，使用Net-SNMP 5.7版本

1. 安装mysql包
   rpm -ivh mysql-community-libs-compat*
   不安装这个包会出现如下报错
   
   

2. 安装

   cd /mnt/Packagesrpm -ivh net-snmpyum install -y net-snmp-perlyum install -y net-snmp-utilsyum install -y net-snmp-develyum install -y net-snmp-lib

3. 验证
   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
   

4. 配置snmpd.conf
   vi /etc/snmp/snmpd.conf

5. 运行snmpd 且开机自启动
   

   chkconfig snmpd onsystemctl start snmp

6. 可通过如下命令检查snmpd是否启动
   netstat -na | grep 161
   
   或
   ps aux | grep snmp
   

7. 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
