Setting elasticsearch with ubuntu-server

In this post I will be writing steps to set up an ubuntu server to run elasticsearch on it.

Setting up ubuntu server

You will need a usb at least 4 gb in size.

Download ubuntu server from here.
Create a bootable usb stick with the server iso using the steps from How to create a bootable USB stick on Ubuntu
Use the usb to boot the laptop in which you want to setup the server
Install the ubuntu server as explained in this askubuntu answer.
In between you might get following error:

``` Your installation CD-ROM couldn’t be mounted. This probably means that yhe CD-ROM was not in the drive. If so you can insert it and try again.

Retry mounting the CD-ROM?
``` The error is coming because the setup needs the `ubuntu server iso` to be mounted to `/cdrom`. There are many solutions suggested on web (like [this](http://ubuntuforums.org/showthread.php?t=1750464), [this](https://pricklytech.wordpress.com/2013/04/21/ubuntu-server-unattended-installation-custom-cd/)) which were suggesting to mount the iso to `cdrom` manually. But nothing worked for me except [this silly answer](http://askubuntu.com/a/614902/78177).
After this restart the server and login.

Setting up network

There are many ways suggested on web like this, this, this, but what worked for me is Ubuntu 14.04 Server - WiFi WPA2 Personal.

Also in case you get confused router-ssid is the name of the router network you want to connect to.

Setting up ssh server

Follow Install SSH server on Ubuntu Linux.

Setup Java

cd /opt/
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u51-b16/jdk-8u51-linux-x64.tar.gz"
tar xzf jdk-8u51-linux-x64.tar.gz
apt-get install chkconfig
update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_51/bin/java 3

Setup elasticsearch

Getting es

cd wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.1.zip apt-get install unzip unzip elasticsearch-1.7.1.zip rm *.zip cd elasticsearch-1.7.1/
Configure es

apt-get install vim vi ~/elasticsearch-1.7.1/config/elasticsearch.yml #cluster.name: elasticsearch #node.name: "es-node2" #script.inline: on #script.indexed: on
Setting up templates

Add templates: mkdir ~/elasticsearch-1.7.1/config/templates vi ~/elasticsearch-1.7.1/config/templates/message_template.json # Copy template
Installing plugins

Install kopf plugin: ~/elasticsearch-1.7.1//bin/plugin --install lmenezes/elasticsearch-kopf/1.5.7
Starting es: /bin/elasticsearch

Make es aut start on boot

Again there are many options to do this using upstart, rc.d, rc.local, cron as explained here Add /home/aapa/softwares/elasticsearch-1.7.1/bin/elasticsearch to the /etc/rc.local file as explained in How to run scripts on start up?.

Make system don’t go to sleep on closing lid

Follow Ubuntu Server 13.10 now goes to sleep when closing laptop lid

Switch off the screen

Follow Turn off monitor using command line

Make the system auto startable

As I am using my old laptop to make the server, it doesn’t have much battery backup. In case the system shutdowns due to any reason be it no power, I want it to start automatically.

Right now I am unabel to find any solution for this, but will update soon. The closest resource I found is: Automatic Reboot After Power Failure
