Elastic Stack Elasticsearch

Hello,

I am not able to start elastic search 7.4.2 as service while using elastic search-7.4.2.zip file in centos.

Process of instalaltion:
Step1 : download zip file
Step 2: Extract in folder
Step3 : Create service (elasticsearch-7.4.2.service) file in /usr/lib/systemd/system
service file content is given below -
[Unit]

StandardOutput is configured to redirect to journalctl since

some error messages may be logged in standard output before

elasticsearch logging system is initialized. Elasticsearch

stores its logs in /var/log/elasticsearch and does not use

journalctl by default. If the user also want to enable journalctl

logging, user can simply remove the "quiet" option from ExecStart.

StandardOutput=journal
StandardError=inherit

Welcome!

Please format your code, logs or configuration files using </> icon as explained in this guide and not the citation button. It will make your post more readable.

Or use markdown style like:

```

```

This is the icon to use if you are not using markdown format:

There's a live preview panel for exactly this reasons.

Lots of people read these forums, and many of them will simply skip over a post that is difficult to read, because it's just too large an investment of their time to try and follow a wall of badly formatted text.
If your goal is to get an answer to your questions, it's in your interest to make it as easy to read and understand as possible.
Please update your post.

Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.

Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

May be something is wrong in your elasticsearch.yml file? Did you modify it?

Is it possible to use instead the rpm package which should configure everything for you?
So follow the instructions in this guide: https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html

Hi,
Thanks for your reply,
Yes already i have verified with rpm , it is working fine but my challenge is use zip file where need to create service file manually.

I have mentioned two scenario for zip file
Scenario 1:
after installing execute ./elasticsearch & from bin file on that time it was working fine.

Scenario 2:
After installing and creating service file, execute the below command
systemctl start elasticsearch-7.4.2.service
systemctl status elasticsearch-7.4.2.service

on that time i am getting error
elasticsearch-7.4.2.service - Elasticsearch-7.4.2

Great. Wondering why you don't want to use the best practices here.
May be you should look at the script that rpm created and uses them as a template?

I'm not on the ops side so I can't help more I'm afraid. May be others?
