In this guide I’ll discuss how to install and configured SNMP service on CentOS5/6 or other linux system.
Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.
1. To install net-snmp in CentOS run the following command.
yum install net-snmp-utils
Output would be:
[root@pir8g33k ~]# yum install net-snmp-utils Loading "fastestmirror" plugin Loading "dellsysidplugin" plugin ... ...

2. After install snmp, reate a simple SNMP configuration and dont forget to backup the original config with the following command.
mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org
Create a new config file to /etc/snmp/snmpd.conf :
vim /etc/snmp/snmpd.conf
rocommunity public
syslocation “pir8g33k DataCenter”
syscontact [email protected]
3. Start the SNMP service:
chkconfig snmpd on /etc/init.d/snmpd start
4. Test if the snmp service working fine by the following command.
snmpwalk -v 1 -c public -O e 127.0.0.1
or
snmpwalk -v 2c -c public 127.0.0.1
5. Make sure to add snmpd to auto-start on reboot:
chkconfig snmpd on
Note: replace the 127.0.0.1 by the server ip address.
Enjoy…cya
