1.移植所需要的环境
ubuntu 10.4
Arm-linux-gcc：3.4.1
Net-snmp：v5.7.2
Target CPU：ok6410
2.配置net-snmp
（1）指定交叉编译器：arm-linux-gcc安装成功并已设置好环境变量。
export PATH=$PATH:.../tools/arm-linux/cc/bin
（2）配置net-snmp编译选项：
net-snmp-5.7.2.tar.gz可在官网（http://www.net-snmp.org/）上下载。
解压后进入net-snmp-5.7.2目录
./configure
--build=i686-linux //编译平台
--host=arm-linux //运行平台
CC=arm-linux-gcc //交叉编译器
--with-endianness=little //指定小端
--enable-mini-agent //最小的SNMP（编译出来的SNMP比较小）
--with-install-prefix=/home/wfj/net-snmp //安装目录
--with-ar=arm-linux-ar //arm-linux-ar二进制工具用来管理文件
LDFLAGS="-static"//静态编译
各配置选项含义可以使用./configure –help来查看，可以添加自己需要的选项或者去掉不需要的选项。
编译完有出现以下提示，一直按回车就行
system contact information (root@):
system Location (Unknown):
3.编译 make
出现.../bin/ld: cannot find lperl.
（1）根据错误准诉到bin/ld所在的文件夹，例如.../arm-none-linux/bin/ld.
（2）找到libperl.so所在文件
find /..../arm-none-linux -name libperl.so
（3）在（1）中的文件下建立一个链接libperl.so，链接到（2）找到的libperl.so
如果仍然不OK，查看错误处看指定的lib位置，在该处建立libperl.so的链接：
ln -s /home/jerry/project/..../libperl.so /usr/local/lib/libperl.so
4.安装 make install
编译得到的snmpd比较大，需要进行strip处理，使用arm-linux-strip snmpd处理后得到需要的snmpd文件。Snmpd在/home/wfj/net-snmp/usr/local/sbin目录下。
5.拷贝配置文件模板
将EXAMPLE.conf文件复制到/home/wfj/net-snmp/usr/local/share/snmp/，并重名为snmpd.conf
#cp EXAMPLE.conf /home/wfj/net-snmp/usr/local/share/snmp/snmpd.conf
6.修改配置文件
#gedit /home/wfj/net-snmp/usr/local/share/snmp/snmpd.conf
找sec.name把原来
# sec.name source community
com2sec local localhost COMMUNITY
com2sec mynetwork NETWORK/24 COMMUNITY
改为一下：
# sec.name source community
#com2sec local localhost COMMUNITY
com2sec mynetwork 192.168.0.233 public
其中192.168.0.233是我开发板的IP
7.移植文件
在移植以前要确保有一下文件：
1./home/wfj/net-snmp/usr/local/net-snmp/sbin/目录下有snmpd进程
2./home/wfj/net-snmp/usr/local/net-snmp/share/snmp/目录下有snmpd.conf ，mibs
3./home/wfj/net-snmp/usr/local/net-snmp/bin目录下有net-snmp-config, snmpwalk, snmpget等
备注：snmpd,net-snmp-config,snmkwalk,snmpget等工具在移植以前，要先用arm-linux-strip压缩一下。
然后把snmpd拷贝到开发板的/usr/sbin中，snmpd.conf拷贝到开发板的/usr/local/share/snmp/中。Mibs目录及目录中的文件考到开发板的/usr/local/share/snmp目录下。开发板上没有的目录就自自己创建。
8.在开发板上运行snmp
#snmpd -c /usr/local/share/snmp/snmpd.conf
会出现一下错误：
snmpd: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory
说明在开发板的lib文件夹中缺少libgcc_s.so.1文件，这时我们需要在交叉编译器中找到这个文件，然后拷贝到开发板的lib文件中。再一次运行snmpd -c /usr/local/share/snmp/snmpd.conf，就不会出现上面那种错误了。
备注：
1.原来snmpd.conf在/home/wfj/net-snmp/usr/local/net-snmp/share/snmp/snmpd.conf中，当传到开发/usr/local/share/snmp/板目录中时，需要在运行时用参数C来指定最新目录。
2.当snmpd进程运行时会在/var/net-snmp目录下创建一个snmpd.conf。
创建V3用户
# net-snmp-config --create-snmpv3-user ↙
# 输入用户名（wangfajun）↙
# 输入authentication pass-phrase(验证)如12345678长度不小于8
# 输入encryption pass-phrase(加密)如12345678，直接回车则跟上面一样。
下图为操作截图：
测试：
snmpget -v 3 -c authPriv -u wangfajun -A "12345678" -X "12345678" localhost sysUpTime.0
注意v3中authprotocal MD5 SHA Privprotocal DES AES
客户端能ping通运行snmpd进程的设备，但取不到值，可能是客户端防火墙问题，取消客户端防火墙试试。
