Facing issue to start elasticsearch "permission denied"


(Harshal Yeole) #1

Hi,
I have added x-pack to the elastic search but after doing so, I am not able to start using

service elasticsearch start 
sudo service elasticsearch start 
bin/elasticsearch

but I'm getting permission denied errors.

I am attaching the SS of the permission for the file directories

For service elasticsearch start

bin/elasticsearch

Permissions
etc

usr-share.

Thanks

You do not have x permission on the plugins directory. I would be tempted to

find /usr/share/elasticsearch -type d -exec chmod +x {} \;

Hi @Badger,

It added the x permissions but I have whole new errors now.

New permissions:

:/usr/share/elasticsearch# ls -l

What do you get from an ls?

ls -l /usr/share/elasticsearch/plugins/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller

I would expect /var/log to only be writeable by root. If the service does not run as root you would need to to create the directory and chown it to whichever id the service runs as.

You have a seriously messed up server. Is re-provisioning and starting from scratch an option? Otherwise

chmod +x /usr/share/elasticsearch/plugins/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller
chmod +x /var/log

(Harshal Yeole) #7

Hi @Badger,

I think we can do re-provisioning and starting from scratch...

I want to add some data and see visualisations using Kibana but also, I want to add few users who will have following roles:

  • Admin
  • User
  • Anonymous User

And based on this roles I want the data and visualisations to be changed, like by permissions and access control.

Can you answer few of my question?

  1. How can we achieve this?
  2. If by ELK, then what should be the priority of installation?
  3. I am using Ubuntu, is it less compatible with Ubuntu?
  4. Can you share links to follow to achieve the above scenario?
  5. How much time it should take, to achieve the goal here?

Thanks


#8

I do not use Ubuntu or x-pack security, so I cannot really address those questions.
