拷贝net-snmp-5.7.2.tar.gz到目录 /downloads下
解压缩
# tar -xzvf net-snmp-5.7.2.tar.gz
# cd net-snmp-5.7.2
执行配置命令
# ./configure --prefix=/usr/local/net-snmp
--with-default-snmp-version="3"
--with-sys-contact="[email protected]"
--with-sys-location="China"
--with-logfile="/var/log/snmpd.log"
--with-persistent-directory="/var/net-snmp"
--enable-mfd-rewrites
解释:
prefix:net-snmp将要安装的路径
enable-mfd-rewrites:允许用新的MFD重写可用的mid模块
with-default-snmp-version:默认的SNMP版本
with-sys-contact:可以配置该设备的联系人
with-sys-location:该设备的位置
with-logfile:日志文件路径
with-persistent-directory:不变数据存储目录编译
# make
安装
# make install
配置snmpd.conf
首先:进入/usr/local/net-snmp/share/snmp
# cd /usr/local/net-snmp/share/snmp
接着:使用配置向导创建snmpd.conf
# ../../bin/snmpconf -g basic_setup
继续:拷贝新创建的snmpd.conf到提示的目录“/usr/local/net-snmp/share/snmp/”The following installed configuration files were found: 1: /usr/local/net-snmp/share/snmp/snmpd.conf Would you like me to read them in? Their content will be merged with the output files created by this session. Valid answer examples: "all", "none","3","1,2,5" Read in which (default = all): none ************************************************ *** Beginning basic system information setup *** ************************************************ Do you want to configure the information returned in the system MIB group (contact info, etc)? (default = y): y Configuring: syslocation Description: The [typically physical] location of the system. Note that setting this value here means that when trying to perform an snmp SET operation to the sysLocation.0 variable will make the agent return the "notWritable" error code. IE, including this token in the snmpd.conf file will disable write access to the variable. arguments: location_string The location of the system: tianjin Finished Output: syslocation tianjin Configuring: syscontact Description: The contact information for the administrator Note that setting this value here means that when trying to perform an snmp SET operation to the sysContact.0 variable will make the agent return the "notWritable" error code. IE, including this token in the snmpd.conf file will disable write access to the variable. arguments: contact_string The contact information: [email protected] Finished Output: syscontact [email protected] Do you want to properly set the value of the sysServices.0 OID (if you don't know, just say no)? (default = y): no ************************************** *** BEGINNING ACCESS CONTROL SETUP *** ************************************** Do you want to configure the agent's access control? (default = y): Do you want to allow SNMPv3 read-write user based access (default = y): n Do you want to allow SNMPv3 read-only user based access (default = y): n Do you want to allow SNMPv1/v2c read-write community access (default = y): n Do you want to allow SNMPv1/v2c read-only community access (default = y): y Configuring: rocommunity Description: a SNMPv1/SNMPv2c read-only access community name arguments: community [default|hostname|network/bits] [oid] The community name to add read-only access for: public The hostname or network address to accept this community name from [RETURN for all]: The OID that this community should be restricted to [RETURN for no-restriction]: Finished Output: rocommunity public Do another rocommunity line? (default = y): n **************************************** *** Beginning trap destination setup *** **************************************** Do you want to configure where and if the agent will send traps? (default = y): n **************************************** *** Beginning monitoring setup *** **************************************** Do you want to configure the agent's ability to monitor various aspects of your system? (default = y): n The following files were created: snmpd.conf /usr/local/net-snmp/share/snmp/ snmpd.conf These files should be moved to /usr/local/net-snmp/share/snmp if you want them used by everyone on the system. In the future, if you add the -i option to the command line I'll copy them there automatically for you. Or, if you want them for your personal use only, copy them to /root/.snmp . In the future, if you add the -p option to the command line I'll copy them there automatically for you.
# snmpd.conf /usr/local/net-snmp/share/snmp/
启动服务
# cd /usr/local/net-snmp/sbin
# ./snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf &
检查服务
# ps -ef | grep snmpd

设置net-snmp自启动
在/etc/rc.local文件的末尾加上如下所示代码
/usr/local/net-snmp/sbin/snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf &
设置环境变量
在/etc/profile文件中export前面添加如下代码
PATH=/usr/local/net-snmp/sbin:/usr/local/net-snmp/bin:$PATH
LD_LIBRARY_PATH=/usr/local/net-snmp/lib:$LD_LIBRARY_PATH
localhost测试
# snmpwalk -v 2c -c public localhost if
