In this guide I’ll discuss how to install and configured SNMP service on CentOS5/6 or other linux system.

1. To install net-snmp in CentOS run the following command.

2. After install snmp, reate a simple SNMP configuration and dont forget to backup the original config with the following command.

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:
