linux系统安装snmp服务以及配置

admin

首先需要安装：

[root@controller ~]#dnf install -y net-snmp-utils net-snmp

（3）测试远端主机是否可以获取数据。
: @5 ~3 ^6 z. S* `* i+ w我这里登陆了另外一台Linux主机，该主机也按照上面的步骤安装好snmp服务及snmp工具。通过这台主机，获取远端主机的数据，这时需指定远端主机的IP地址：

以上安装完成后，使用的是snmp的默认配置，通过这些默认配置，我们只能获取主机的部分信息。但一些其他的重要信息，无法获取。如主机的CPU使用情况，内存使用情况等。

[root@controller ~]# snmpwalk -v 2c -c public 192.168.8.66 1.3.6.1.4.1.2022.06.12.0

如上，无法获取CPU的空闲率（注：1.3.6.1.4.1.2021.11.11.0是主机CPU空闲率的oid）。这时候，若要获取主机的一些重要信息，则要修改snmp的默认配置。

修改团体名

在配置文件中找到修改成如下：

com2sec notConfigUser  default       simware

修改查看设备节点的权限

添加：

view    systemview    included   .1

* h/ M' @  s: Z- \/ J: }. S3 o% J

修改Process checks的配置

去掉下面三个参数的#号

#  Make sure mountd is running
( m5 m9 I1 u  L& J/ p' Eproc mountd

#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
proc ntalkd 4

#  Make sure at least one sendmail, but less than or equal to 10 are running.
proc sendmail 10 1

修改Executables/scripts配置

以及exec的#号

exec echotest /bin/echo hello world

修改disk checks配置

/ P. J- I+ T! l  s- n: G

disk / 10000

# }7 f9 n7 ?$ L( j

修改load average checks配置

load 12 14 14

保存修改，重启snmp服务

systemctl restart snmpd.service

There are lots of options (this post is a very basic howto. You can read the manpage for further information), but basically I use snmpwalk this way depending on the SNMP version:
* m7 u6 `7 J& {/ r
snmpwalk -v1 -c <COMMUNITY> <HOST> <OID>
snmpwalk -v2c -c <COMMUNITY> <HOST> <OID>
' Y6 Z$ K: w3 O# R; v& }snmpwalk -v3 -l authNoPriv -u <USER> -A <PASSWORD> <HOST> <OID>
& T. L$ q: o  t3 [8 ^) H. F
