I have upgraded from ElasticSearch 5.6.2 to 6.0.0 on Centos 7 and am getting the following error when trying to start the service:
Nov 24 16:18:37 desktopoli systemd: Starting Elasticsearch...
Nov 24 16:18:37 desktopoli systemd: Failed at step EXEC spawning /usr/share/elasticsearch/bin/elasticsearch-systemd-pre-exec: No such file or directory
Nov 24 16:18:37 desktopoli systemd: elasticsearch.service: control process exited, code=exited status=203
Nov 24 16:18:37 desktopoli systemd: Failed to start Elasticsearch.
Nov 24 16:18:37 desktopoli systemd: Unit elasticsearch.service entered failed state.
Nov 24 16:18:37 desktopoli systemd: elasticsearch.service failed.
Any idea on how to fix?

Hi, can you provide Elasticsearch logs as well ?
Something like :
tail -100f /var/log/elasticsearch/your\_cluster\_name.log

It seems that when path.data is not configured(commented out) in elasticsearch.yml, in 6.0 ElasticSearch will try to configure /usr/share/elasticsearch/logs/ and log there.
Anyway, this is where I am at now:

I get the same error for [default.path.data] and [default.path.logs] please check that any required plugins are installed, or check the breaking changes documentation for removed settings
But i do not have this configured in elasticsearch.yml anywhere...

Probably you didn’t update the startup scripts

Thanks for your reply. Can you please detail what needs to be changed in each file? Is manually hanging startup scripts always have to be done during upgrade procedure? I am following following documentation, point 4 for upgrading with RPM:
[https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html)

No I can’t. I’m afraid I don’t know about scripts and Linux packaging. May be @tlrx or @warkolm know?

I have changed the following ffile with modifications:
/usr/lib/systemd/system/elasticsearch.service
ExecStart=/usr/share/elasticsearch/bin/elasticsearch
-p ${PID\_DIR}/elasticsearch.pid
--quiet
-Epath.logs=${LOG\_DIR}
-Epath.data=${DATA\_DIR} \
I also had to change the following in same file:
#Specifies the maximum number of processes
LimitNPROC=4096
Then I reloaded service and started Elasticsearch and all works well.
systemctl daemon-reload
systemctl start elasticsearch
Thanks for pointing me in right direction.
