snmpd 编译安装 分享

安装配置
# cd /tmp

# tar -zxvf net-snmp-5.3.0.1.tar.gz
 
# cd net-snmp-5.3.0.1

# ./configure –prefix=/usr/local/snmpd –enable-mfd-rewrites

注意：snmp协议选择v2c

# make && make install

启动snmpd服务：
mkdir /usr/local/snmpd/etc/
touch /usr/local/snmpd/etc/snmpd.conf
vi /usr/local/snmpd/etc/snmpd.conf

com2sec notConfigUser   default      auto
group   notConfigGroup v1            notConfigUser
group   notConfigGroup v2c           notConfigUser
view    all           included   .1     80
access  notConfigGroup ""      any       noauth    exact  all        none none

/usr/local/snmpd/sbin/snmpd -c /usr/local/snmpd/etc/snmpd.conf

测试是否安装成功：
netstat -na |grep 161

udp        0      0 0.0.0.0:161                 0.0.0.0:*      

 

执行： snmpwalk -v2c -c auto 127.0.0.1 system

制作snmpd 开机启动脚本
cd /etc/rc.d/init.d
touch snmpd
vi snmpd

##########  这里我偷懒，拷贝直接在之前的snmp rpm包安装完后系统制作的启动脚本，然后修改完成，并非我写的。

###############################################
chmod +x snmpd

chkconfig --level 3 snmpd on

然后就可以使用如下命令重启snmpd 服务了。
 service snmpd restart
同时，服务器在重启后，snmpd 会自动重启
