But the service was not running.
[root@mailman snmp]# ps -ef | grep snmpd
root 3667 3369 0 19:40 pts/2 00:00:00 grep snmpd
See, no snmpd.pid found in the process list. Or type service snmpd status, you will see the result that snmpd is stopped.
[root@mailman snmp]# service snmpd status
snmpd is stopped
Now, how do you start that service? Type service snmpd start, and you will see [OK] message that means the snmpd service now started.
