这是基于LAMP架构基础上的，LAMP安装之前已经介绍，这里不再讨论

============================================================================
修改snmpd.conf
1.查找以下字段：
# sec.name source community
com2sec notConfigUser default public
将"comunity"字段改为你要设置的密码.比如"bizcnpublic".
将“default”改为你想哪台机器可以看到你的snmp信息,如10.10.10.10。授权服务器IP
2.查找以下字段：
####
# 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
将"read"字段改为 all.
代码:
#access notConfigGroup "" any noauth exact all none none
3.查找以下字段：
## incl/excl subtree mask
#view all included .1 80
将该行前面的"#"去掉.
disk /
保存、关闭
