Linux (Ubuntu/CentOS) SNMP配置

在这里使用默认团体名public,实际环境中建议更改。

1.将原有“agentAddress udp:127.0.0.1:161”改为:

agentAddress 192.168.1.9 /*192.168.1.9为本机IP,即监控服务器要监控的主机IP*/

2.加入一行如下:

access MyROSystem "" any noauth exact all none none

3.将原有“rocommunity public default -V systemonly” 的"-V systemonly" 参数去掉,变成:

rocommunity public default

4.将“#trap2sink localhost public”和“#informsink localhost public”前面的“#”去掉,改为:

trap2sink localhost public

informsink localhost public

5.重启SNMP服务:

/etc/init.d/snmpd restart

6.检验snmp获取数据:

snmpwalk -v 2c -c public 192.168.1.9

CentOS6.3下的SNMP配置:

安装SNMP服务:

yum install net-snmp net-snmp-devel net-snmp-libs net-snmp-utils php-snmp
编辑snmpd文件:

vi /etc/snmp/snmpd
第一步,snmp团体名默认为public,可更改为其他,如下:
# First, map the community name "public" into a "security name"
# sec.name source community
com2sec notConfigUser default public

第二步,将如下位置的systemview改为all,如下:
####
# Finally, grant the group read-only access to the systemview view.
# group context sec.model sec.level prefix read write notif
#access notConfigGroup "" any noauth exact systemview none none
access notConfigGroup "" any noauth exact all none none

第三步,将如两行下行前面的注释去掉,如下:
## incl/excl subtree mask
view all included .1 80
## -or just the mib2 tree-
view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc

第四步,将下面这行前的注释去掉,如下:
#access notConfigGroup "" any noauth exact roview rwview none
access notConfigGroup "" any noauth exact mib2 none none

第五步,启动snmpd,并设置开机自动启:
service snmpd restart
chkconfig --level 345 snmpd on
