net-snmp安装日志

1.从下载最新版本5.4.1.2源代码

2.拷贝到/root/src目录下

3.tar -zxvf net-snmp-5.4.1.tar.gz

4.cd net-snmp-5.4.1
5../configure
6.make
7.make install

configure后返回的configure信息

8.在编译过程中可能会碰到一些问题

参考解决

This has been seen in a number of guises over the years - most commonly on Linux systems (although the problem may also occur elsewhere). A typical installation may not always include the full set of library links required for building the Net-SNMP software.

This problem can usually be fixed by installing the missing packages (typically the development version of a package that is already there).

Examples of this that we have come across include:

    -lelf       elfutils-devel      (later renamed to elfutils-libelf-devel)
    -lbz2       bzip2-devel
    -lselinux   libselinux-devel
    -lcrypto    openssl/openssl-devel
    -lbeecrypt  libbeecrypt/beecrypt/beecrypt-devel.

These are the names of the RedHat/Fedora RPMs. Other distributions or O/S's may use different names, but the basic idea should be the same.

If the compilation is complaining about a missing .so file, then an alternative quick fix is to add the missing symbolic link, using something like:

         ln -s libelf.so.1 /usr/lib/libelf.so
 

giving the appropriate generic library name from the error message, and the correct number for whichever version of this library you have installed.

9.运行snmptranslate 测试是否可以正确解析OID

可以参考：

几个选项介绍如下：

a.-On 用数字形式输出

b.-Of 输出完整名字

c.-IR

  OID的形式一般需要这样提供的

     模块名::mib object的最底层名字 例如：SNMPv2-MIB::sysUpTime.0

  -IR 选项使得用户可以不用提供前面的模块名

d.-Tp  -Td  用户提供OID的时候不需要加后缀.0

  -Tp  打印该节点树的详细信息

  -Td  输出该节点的详细信息

10.参照教程 简单配置windows下的snmp服务

  在linux下用snmpget snmpwalk 等工具访问成功

  对snmp有个感性认识

11.开始配置linux下的snmp agent

  检测snmpd是否运行

  %snmpwalk -v 1 -c public 127.0.0.1 SNMPv2-MIB::sytem

  返回　No response from 127.0.0.1

  说明SNMPv2-MIB::sytem 已经解析成功，但是snmpd没有反应

  %netstat -apn | grep 161

  %ps -aux | grep -i snmpd

  都没有关于snmpd的信息返回，说明snmpd没有运行

12.后台运行snmpd

  %snmpd &

  如果失败，就要仔细检查/usr/local/etc/snmp  下的snmpd.conf 文件是否配置正确

  不是 /etc/snmp/ 下的snmpd.conf 文件哦，它没有执行权限

13. %snmpwalk -v 1 -c public 127.0.0.1 SNMPv2-MIB::sytem

  成功访问！
