Configure SNMP Using Ansible Playbook Linux Best Examples

In last ansible article i have explained How to Write your First Playbook without error’s. In this article i am going to explain HowTo configure SNMP Using Ansible Playbook. SNMP – Simple Network Monitoring Protocol which is used to monitor Servers, Network Devices and any devices which support SNMP. See SNMP Installation and configuration.

Configure SNMP Using Ansible Playbook

If you do not use ansible automation tool you have to login to each and every server and configure SNMP for monitoring manually. Doing manual job may require at least 5 minutes for host.

First time snmp installation. You have to place snmpd.conf file in http/web server to download standard configuration file. You can also use default configuration from ansible snmp module.

- hosts: all
  remote_user: ravi
  become: yes
  become_method: sudo
  gather_facts: yes
  vars:
  tasks:

- name: Install snmp packages
 yum: name=net-snmp state=latest

- name: Enable snmp service
 service: name=snmpd enabled=yes
 notify: Restart snmpd

- name: Download snmpd config file
 get_url:
 url: http://192.168.2.8/snmpd.conf
 dest: /tmp/snmpd.conf

copy: src=/tmp/snmpd.conf dest=/etc/snmp/snmpd.conf owner=root group=root mode=644
 notify: Restart snmpd

handlers:
 - name: Restart snmpd
 action: service name=snmpd state=restarted

After SNMP Installation change community string

As per my requirement i have to change SNMP community string after successful configuration. Below is the ansible playbook i used and accomplished job successfully.

- hosts: all
 remote_user: ravi
 become: yes
 become_method: sudo
 tasks:
 - name: Insert New line
 blockinfile:
 path: /etc/snmp/snmpd.conf
 insertafter: "rocommunity"
 content: |
 rocommunity private 192.168.3.7

- name: Restart SNMPD Service
 action: service name=snmpd state=restarted
