freeBSD与openBSD下SNMP服务的安装与配置

一、freeBSD安装SNMP服务

1、检查主机是否已经安装SNMP服务

2、安装配置SNMP服务

2.1安装SNMP服务

切换至root用户，执行：

#cd /usr/ports/net-mgmt/net-snmp/

#makeinstallclean

根据系统提示完成在线安装

      方法二：snmp源代码编译安装

#scproot@192.168.0.174:源代码文件绝对路径 .  //“.”代表当前目录

#tarxvzfnet-snmp-5.5.2.1.tar.gz

#cdnet-snmp-5.5.2.1

#./configure

#make

#makeinstall

方法三：

#pkgaddnet-snmp

2.2配置SNMP服务

编辑/etc/rc.conf文件，完成snmp自启动环境

添加如下内容：

snmpd_enable="YES"

snmpd_flags="-a/var/run/snmpd.pid"

snmptrapd_enable="YES"

snmptrapd_flags="-a-p/var/run/snmptrapd.pid

2.3生成snmp.conf配置文件

先删除snmp原始配置文件，执行以下命令生成符合监控要求的snmpd.conf

#snmpconf-gbasic_setup

运行后会出现一个询问菜单，按如下步骤进行回答：

doanotherloadline?(default=y):n
doyouwanttoconfiguretheagentsabilitytomonitorfilesizes?(default=y):n（如果想监控文件的大小，可以选y）

 上述命令执行完成后会在/usr/local/share/snmp目录下生成snmp.conf

3、启动SNMP服务

4、验证SNMP服务

5、远程主机测试

6、关于配置文件的说明

7、查看防火墙状态

二、 openBSD安装snmp服务

1、检查是否安装snmp服务

2、安装配置snmp服务

（3）运行snmpconf-gbasic_setup生成snmp配置 //与freeBSD配置snmp一样

（4）将生成在/usr/local/share/snmp目录下的snmpd.conf文件替换到/etc/snmp/目录下
