今天做了snmp的測試，現(xiàn)把安裝配置方法分享如下：

   首先準備安裝的源碼包：net-snmp-5.4.2.1.tar.gz

1.解壓源碼包
  tar xvf net-snmp****
2.創(chuàng)建安裝目錄
  mkdir /usr/local/net-snmp
3.安裝
  ./configure --prefix=/usr/local/net-snmp
  make
  make install
4.安裝成功cp配置文件到/usr/local/net-snmp/share/snmp/目錄下
  cp ./EXZAPLE.conf /usr/local/net-snmp/share/snmp/snmpd.conf
5.修改配置文件
  #       sec.name  source          community
  #com2sec local     localhost       COMMUNITY
  #com2sec mynetwork NETWORK/24      COMMUNITY
  com2sec local     localhost       COMMUNITY
  com2sec mynetwork 192.168.1.186      public      //為允許的源地址
  com2sec mynetwork 192.168.1.254      public
  com2sec mynetwork 192.168.1.0/24      public     //為允許的源網(wǎng)絡(luò)
6.編輯/etc/rc.local添加為自啟動  
  添加下面一行：
  /usr/local/net-snmp/sbin/snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf &
7.設(shè)置環(huán)境變量，編輯/etc/profile
  在export前添加下面一行
  PATH=/usr/local/net-snmp/bin:/usr/local/net-snmp/sbin:$PATH
8.測試命令
  snmpget -v 1 -c "public" 192.168.1.236 .1.3.6.1.4.1.2021.10.1.3.1
  注：要在同樣安裝過net-snmp的機器上測或在安裝過第3方軟件（solarwinds等）的機器測試
      該命令的最后一個字段為cpu的OID  
 

問題補充：

       上次裝好netsnmp并觀察了一段時間后發(fā)現(xiàn)獲取內(nèi)存，cpu信息等等都很正常，唯獨磁盤信息與預(yù)期有點出入，我們預(yù)期獲取磁盤所有分區(qū)的使用情況結(jié)果只獲取了/根分區(qū)的使用情況:

       經(jīng)查證是配置文件snmpd.conf里的配置有關(guān)：

# disk checks
#

# The agent can check the amount of available disk space, and make
# sure it is above a set limit.

# disk PATH [MIN=DEFDISKMINIMUMSPACE]
#
# PATH:  mount path to the disk in question.
# MIN:   Disks with space below this value will have the Mib's errorFlag set.
#        Default value = DEFDISKMINIMUMSPACE.

# Check the / partition and make sure it contains at least 10 megs.

# % snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.9
# enterprises.ucdavis.diskTable.dskEntry.diskIndex.1 = 0
# enterprises.ucdavis.diskTable.dskEntry.diskPath.1 = "/" Hex: 2F
# enterprises.ucdavis.diskTable.dskEntry.diskDevice.1 = "/dev/dsk/c201d6s0"
# enterprises.ucdavis.diskTable.dskEntry.diskMinimum.1 = 10000
# enterprises.ucdavis.diskTable.dskEntry.diskTotal.1 = 837130
# enterprises.ucdavis.diskTable.dskEntry.diskAvail.1 = 316325
# enterprises.ucdavis.diskTable.dskEntry.diskUsed.1 = 437092
# enterprises.ucdavis.diskTable.dskEntry.diskPercent.1 = 58
# enterprises.ucdavis.diskTable.dskEntry.diskErrorFlag.1 = 0
# enterprises.ucdavis.diskTable.dskEntry.diskErrorMsg.1 = ""
因為配置文件默認只有disk / 10000這一行；按此格式添加你期望獲取的磁盤或分區(qū)；

it‘s ok！！問題解決；
