1.下载net-snmp
http://net-snmp.sourceforge.net/download.html
例如，下载5.5版本
2.进入下载目录，解压net-snmp压缩包
#tar zxf net-snmp-5.5.tar.gz
3.configure
#cd net-snmp-5.5
#./configure --with-default-snmp-version="2" --with-sys-contact="contact@contact" --with-sys-location="location" --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp"
4.make
# make
# make install
5.配置conf文件
# vi /etc/snmpd.conf
在 snmpd.conf 中輸入一行：
rocommunity public
:wq 保存并退出
6.启动
# snmpd -C -c /etc/snmpd.conf
7.检验mib2c
# mib2c
如果出现以下：
Use of uninitialized value $key in hash element at /usr/local/lib/perl/5.10.1/SNMP.pm line 1325.
Use of uninitialized value $key in hash element at /usr/local/lib/perl/5.10.1/SNMP.pm line 1326.
Use of uninitialized value in null operation at /usr/local/lib/perl/5.10.1/SNMP.pm line 1325.
You didn't give mib2c a valid OID to start with. IE, I could not find
any information about the mib node "". This could be caused
because you supplied an incorrectly node, or by the MIB that you're
trying to generate code from isn't loaded. To make sure your mib is
loaded, run mib2c using this as an example:
env MIBS="+MY-PERSONAL-MIB" mib2c
You might wish to start by reading the MIB loading tutorial at:
http://www.net-snmp.org/tutorial-5/commands/mib-options.html
And making sure you can get snmptranslate to display information about
your MIB node. Once snmptranslate works, then come back and try mib2c
again.
证明可用，搭建完成。
