How to start a service automatically after restarting a vagrant box? - elasticsearch

Question

I installed elasticsearch using this role.
I do the following steps in the playbook:
---
- hosts: master
sudo: true
tags: elasticsearch
roles:
- ansible-elasticsearch
And then vagrant up es-test-cluster, where es-test-cluster is the name of the VM I mention in VagrantFile. I have given it a private IP 192.162.12.14. The VM boot perfectly and after running sudo service elasticsearch status I get that the service is running on 192.162.12.14:9200 which is correct. But if I run vagrant halt es-test-cluster and then vagrant up es-test-cluster I see that the elasticsearch service is running any more.
I thought of doing this:
---
- hosts: master
sudo: true
tags: elasticsearch
roles:
- ansible-elasticsearch
tasks:
- name: Starting elasticsearch service if not running
service: name=elasticsearch state=started
but even this does not help. This only runs when I boot for the first time.
How can start the service whenever I run vagrant up?
This is for Ubuntu 14.04.

Answer 1

You need to "enable" the service. This can be done with a single flag in your Ansible.
---
- hosts: master
sudo: true
tags: elasticsearch
roles:
- ansible-elasticsearch
tasks:
- name: Starting elasticsearch service if not running
service:
name: elasticsearch
state: started
enabled: true
Also, depending on which ansible-elasticsearch role you are using, it may already have a flag that you can pass to enable the service without the extra task. I know the role I used did.

The solutions are for Debian packages.
You can include the following in the VagrantFile:
config.vm.provision "shell", path: "restart_es.sh"
where restart_es.sh contains:
#!/bin/bash
SERVICE=elasticsearch;
sudo update-rc.d $SERVICE defaults 95 10
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
echo "$SERVICE is not running"
sudo /etc/init.d/$SERVICE start
fi
OR
config.vm.provision "shell", path: "restart_es.sh", run: "always"
where restart_es.sh contains:
#!/bin/bash
SERVICE=elasticsearch;
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
echo "$SERVICE is not running"
sudo service $SERVICE start
fi
OR
config.vm.provision "shell", inline: "sudo service elasticsearch start", run: "always"
All three start the elasticsearch service when you restart the vagrant box.
