What happens if you try to start it? Please share the full output.

Code: Select all

service elasticsearch start

How much ram / disk space did you allocate to the machine, and how many CPU's?

[Naveed]

Service elasticsearch starts the service, but it alse went to down state with following error message.

[root@localhost ~]# service elasticsearch start
Starting elasticsearch: [ OK ]
[root@localhost ~]# service elasticsearch status
elasticsearch dead but pid file exists


Moreover machine specs are attached.

Thanks

I don't see any specs attached, could you please post them again?

PFA

[rkennedy]

This simply isn't enough resources for NLS. I would expand the processors to at least 2, and the memory to at least 8GB. As it's java based, the main requirement to use it is going to memory.

[Naveed]

I increased resources and its start working for me.
Please close this thread.

Thanks
