Linux net-snmp-5.7.2安装配置

安装包

软件名称：net-snmp-5.7.2.tar.gz

下载地址：http://sourceforge.net/projects/net-snmp/files/net-snmp/5.7.2/net-snmp-5.7.2.tar.gz/download

安装

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="brusezhu9@gmail.com"


--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 [b]/usr/local/net-snmp/share/snmp[/b]
接着：使用配置向导创建snmpd.conf
# ../../bin/snmpconf -g basic_setup

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: brusezhu9@gmail.com

Finished Output: syscontact  brusezhu9@gmail.com
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.

继续：拷贝新创建的snmpd.conf到提示的目录“/usr/local/net-snmp/share/snmp/”

# 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
root 9244 1 0 15:38 ? 00:00:00 ./snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf

root 9247 27939 0 15:39 pts/1 00:00:00 grep snmpd
说明服务已经正常启动

检测161端口

# lsof -i:161
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

snmpd 9244 root 6u IPv4 445768 0t0 UDP *:snmp

注意：*表示允许所有主机的访问161端口

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

测试

localhost测试
