记录一次线上实施snmp

公司要实施一个部级的项目，我们公司的提供的产品要对接下客户的一个平台监控平台，该监控平台使用snmp，我们公司的产品不支持snmp，所以由我负责在现网实施snmp，记录这次现网

一、生成编译规则

1、下载snmp的tar包

2、解压

[root@localhost admin]# tar -zxvf net-snmp-5.7.1.tar.gz

　　

drwxr-xr-x 18  1274  1274    4096 Sep 28  2011 net-snmp-5.7.1
-rw-rw-r--  1 admin admin 6110619 Jul 23 14:37 net-snmp-5.7.1.tar.gz

　　

3、生成编译规则

./configure --prefix=/usr/local/snmp --with-mib-modules='ucd-snmp/diskio ip-mib/ipv4InterfaceTable'

　　

4、点击回车

5、点击回车：1、default version of-snmp-version:

6、点击回车：Systemcontact information（配置该设备的联系人）:

7、点击回车：System location (该设备的位置):

8、点击回车：Location to write logfile (日志文件位置): /var/log/snmpd.log

9、点击回车：Location to Write persistent(数据存储目录): /var/net-snmp

10、编译规则生成完成

二、安装

1、编译并安装

make  &&  make install

　　

2、编译安装完成

3、在snmp安装目录创建配置文件路径

[root@localhost snmp]# mkdir etc
[root@localhost snmp]# pwd
/usr/local/snmp
[root@localhost snmp]# ll
total 8
drwxr-xr-x 2 root root 4096 Jul 23 14:57 bin
drwxr-xr-x 2 root root    6 Jul 23 14:59 etc
drwxr-xr-x 3 root root   21 Jul 23 14:57 include
drwxr-xr-x 2 root root 4096 Jul 23 14:57 lib
drwxr-xr-x 2 root root   34 Jul 23 14:57 sbin
drwxr-xr-x 4 root root   27 Jul 23 14:57 share

　　

4、在源文件目录下拷贝配置文件到安装的etc目录

[root@localhost snmp]# scp /home/admin/net-snmp-5.7.1/EXAMPLE.conf /usr/local/snmp/etc/snmpd.conf
You have mail in /var/spool/mail/root
[root@localhost snmp]# ll
total 8
drwxr-xr-x 2 root root 4096 Jul 23 14:57 bin
drwxr-xr-x 2 root root   23 Jul 23 15:01 etc
drwxr-xr-x 3 root root   21 Jul 23 14:57 include
drwxr-xr-x 2 root root 4096 Jul 23 14:57 lib
drwxr-xr-x 2 root root   34 Jul 23 14:57 sbin
drwxr-xr-x 4 root root   27 Jul 23 14:57 share
[root@localhost snmp]# cd etc/

　　

[root@localhost etc]# ll
total 8
-rw-r--r-- 1 root root 6993 Jul 23 15:01 snmpd.conf

　　

5、编辑配置文件

a、配置允许网络访问，按照截图中的方式修改

b、选择v2c SNMP协议的版本，按照截图中的方式修改

c、设置访问权限，按照截图中的方式修改

三、启动和调试

1、启动

[root@localhost etc]# /usr/local/snmp/sbin/snmpd -c /usr/local/snmp/etc/snmpd.conf

　　

2、检查进程和端口

[root@localhost etc]# netstat -an |grep -w 161
[root@localhost etc]# ps auxf |grep -w snmp
root     26440  0.0  0.0 112708   980 pts/0    S+   15:10   0:00  |                   \_ grep --color=auto -w snmp

　　

[root@localhost etc]# ps auxf |grep snmp
root      3327  0.0  0.0 112708   956 pts/0    S+   15:11   0:00  |                   \_ grep --color=auto snmp
root      1696  0.2  0.0 187880  5164 ?        S    15:11   0:00 /usr/local/snmp/sbin/snmpd -c /usr/local/snmp/etc/snmpd.conf
[root@localhost etc]# netstat -anu |grep 161
udp        0      0 0.0.0.0:161             0.0.0.0:*
[root@localhost etc]#

　　

3、添加到开机启动项中

4、添加防火墙规则

firewall-cmd --permanent --direct --add-rule ipv4 filter INPUT 1 -s 10.87.18.101/24 -p udp --dport=161 -j ACCEPT

　　

[root@localhost init.d]# firewall-cmd --reload

　　

5、测试

6、附上oid

These Commands you need to run on the SNMP server 
Get available disk space for / on the target host 
# Snmpget-v 1-c "community" target_name_or_ip .1.3.6.1.4.1.2021.9.1.7.1 
this will return available disk space for the first entry in the 'disk' section of snmpd.conf; replace 1 with n for the nth entry
