由于某些设备并不能安装 Agent，或者不方便安装 Agent 等因素，将采用 SNMP 方式进行监控

1、Linux 配置 SNMP 

[root@crazy-acong ~]# yum -y install net-snmp

2、配置 snmp 配置文件

# snmp 原配置文件[root@crazy-acong ~]# egrep -v "^#|^$" /etc/snmp/snmpd.confcom2sec notConfigUser  default       publicgroup   notConfigGroup v1           notConfigUsergroup   notConfigGroup v2c           notConfigUserview    systemview    included   .1.3.6.1.2.1.1view    systemview    included   .1.3.6.1.2.1.25.1.1access  notConfigGroup ""      any       noauth    exact  systemview none nonesyslocation Unknown (edit /etc/snmp/snmpd.conf)syscontact Root 
     
       (configure /etc/snmp/snmp.local.conf)dontLogTCPWrappersConnects yes
     

# 修改后的配置文件[root@crazy-acong ~]# cat /etc/snmp/snmpd.confcom2sec mynetwork 192.168.1.105 public_monitorcom2sec mynetwork 127.0.0.1 publicgroup MyROGroup v2c mynetworkaccess MyROGroup "" any noauth prefix all none noneview all included .1 80

 

3、启动 snmp 服务

[root@crazy-acong ~]# /etc/init.d/snmpd  start[root@crazy-acong ~]# netstat -lnpt | grep snmptcp        0      0 127.0.0.1:199               0.0.0.0:*                   LISTEN      1550/snmpd  [root@crazy-acong ~]# chkconfig snmpd on
