On fresh install Ubuntu 16.04 I use next steps to install ElasticSearch 5.0.1 or 5.0.2 and ES failed to start. Does anyone know how can I run ES 5.x on Ubuntu 16.04 or 14.04?

1. su


2. add-apt-repository ppa:webupd8team/java


3. apt-get update


4. apt-get upgrade


5. apt-get install oracle-java8-installer


6. java -version


7. wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -


8. apt-get install apt-transport-https



9. echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | tee -a /etc/apt/sources.list.d/elastic-5.x.list




10. apt-get update && sudo apt-get install elasticsearch




11. service elasticsearch status

Elasticsearch 5.x failed to start on Ubuntu 16.04.
Does anyone know how can I run ES 5.x on Ubuntu 16.04 or 14.04?

I also try with the new version of Elasticsearch 5.1.1 with this few steps

1. su


2. apt-get purge elasticsearch


3. apt-get update


4. apt-get upgrade


5. apt-get install elasticsearch

-- new version elasticsearch 5.1.1 is installed

6. now if I check status I get this

service elasticsearch status

● elasticsearch.service - Elasticsearch

I had the same issue and I saw that the group of my elasticsearch.yml file was not right. You can check it by using:

ubuntu@mymachine:~$ sudo ls -al /etc/elasticsearch/

total 24

drwxr-x---  3 root elasticsearch 4096 Dec 19 10:58 .

drwxr-xr-x 94 root root          4096 Dec 19 10:58 ..

-rw-rw----  1 root elasticsearch 3069 Dec  6 12:39 elasticsearch.yml

-rw-rw----  1 root elasticsearch 2862 Dec  6 12:39 jvm.options

-rw-rw----  1 root elasticsearch 3992 Dec  6 12:39 log4j2.properties

drwxr-x---  2 root elasticsearch 4096 Dec  6 12:39 scripts

It can be that the elasticsearch.yml is in the root group.

-rw-rw----  1 root root   3069 Dec  6 12:39 elasticsearch.yml

When I changed the group I was able to start elasticsearch again.

$ sudo chgrp elasticsearch /etc/elasticsearch/elasticsearch.yml

I was sceptical and thought I would not be able to find the answer to this question but your (@user305883) advice turned out to be a good. Thanks for help.

I changed /etc/elasticsearch/jvm.option -Xms2g and -Xmx2g to #-Xms2g and #-Xmx2g and on ubuntu terminal after I run this command

service elasticsearch start

ES run well on Ubuntu 16.04.

This was right answer. Thanks again to @user305883.

Worked for me. My jvm.options file:

## JVM configuration



################################################################

## IMPORTANT: JVM heap size

################################################################

##

## You should always set the min and max JVM heap

## size to the same value. For example, to set

## the heap to 4 GB, set:

##

## -Xms4g

## -Xmx4g

##

## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

## for more information

##

################################################################



# Xms represents the initial size of total heap space

# Xmx represents the maximum size of total heap space

--- Commented out ---

#-Xms2g

#-Xmx2g

--- Commented out ---

```

Worked for me as above. Thank you.

I have been facing the same issue (i.e permission denied error while accessing /etc/elasticsearch), I have installed ES 6.0.1 and somehow my ES was failed to start. I came to know that my ES service script located in /etc/init.d/elasticsearch can not be able to read the following files need to run ES:
1) /etc/elasticsearch/elasticsearch.yml
2) /etc/elasticsearch/jvm.options
3) /etc/elasticsearch/log4j2.properties

So, what I did is first given elasticsearch the executable rights:

/etc$ sudo chmod +x elasticsearch

Then after, I given the permission of all the files located in /etc/elasticsearch like this:

/etc/elasticsearch$ sudo chmod 777 .

And then I just restart ES Like this:

sudo systemctl restart elasticsearch

Now, ES is working fine and you can test it by issuing following command

curl -X GET "localhost:9200"

make sure /etc/elasticsearch/log4j2.properties exists, otherwise create it:

appender.console.type = Console

appender.console.name = console

appender.console.layout.type = PatternLayout

appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %marker%m%n



rootLogger.level = info

rootLogger.appenderRef.console.ref = console
