[SOLVED] How do I enable snmp in centos?

lhan17 · 05-17-2012, 09:22 PM

Hi, I have a centos server that I want to monitor with solarwinds. Now, my solarwinds guy told me to enter the community string, let's say "abcdefg" in the centos box. I have two questions.

1. How do I check if snmp is installed/running on centos?
2. In the case that snmp is already installed, how do I enter the community string?

Thanks

You will want to do the following as root:

Code:

yum install net-snmp

Then you will want to edit /etc/snmp/snmpd.conf to configure the service.

Then you will need to:

Code:

chkconfig snmpd on

So the service will start on boot.

And lastly:

Code:

service snmpd start

1. How do I check if snmp is installed/running on centos?

# ps ax | grep snmpd
3924 ? Sl 0:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -p /var/run/snmpd.pid -a
when it show as the following it's mean your snmp running

2. In the case that snmp is already installed, how do I enter the community string?

you can edit the community string on /etc/snmp/snmpd.conf

The community string is located on top and by default it use public as community string but you can edit

# sec.name source community
com2sec notConfigUser default public
