CentOS7 snmp 配置

1. 安装 snmp

yum install net-snmp

如果系统版本较老，可修改yum源为阿里云的镜像源（参考下面链接）

2. 备份 snmpd 配置文件

cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.bak

 

3. 修改 snmpd 配置文件

vi  /etc/snmp/snmpd.conf

以下为参考截图

 

4. 启动 snmpd 服务，并设置为开机启动

systemctl start snmpd

systemctl enable snmpd

firewalld 开放端口 161-162/udp

firewall-cmd --zone=public --add-port=161-162/udp --permanent

firewall-cmd --reload

firewall-cmd --list-all
