Hello:

Could you please check and share logs on /var/log/elasticsearch/* ?

Saplog · May 31, 2017, 8:22am

I just want to said that i have remove all logs files of elasticsearch, then i try to start again elasticsearch and this files appears.

root@elkf:/var/log/elasticsearch# ls -l /var/log/elasticsearch/*
-rw-r--r-- 1 elasticsearch elasticsearch 0 mai 31 11:49 /var/log/elasticsearch/elasticsearch_access.log
-rw-r--r-- 1 elasticsearch elasticsearch 0 mai 31 11:49 /var/log/elasticsearch/elasticsearch_deprecation.log

-rw-r--r-- 1 elasticsearch elasticsearch 0 mai 31 11:52 /var/log/elasticsearch/elasticsearch.log

All of this file are empty.

Xavy · May 31, 2017, 8:27am

Hello @Saplog:

I would then suggest running:

/usr/share/elasticsearch/bin/elasticsearch -p ${PID_DIR}/elasticsearch.pid --quiet -Edefault.path.logs=${LOG_DIR} -Edefault.path.data=${DATA_DIR} -Edefault.path.conf=${CONF_DIR}

Changing variables to the appropriate value as stated on the systemctl config file

This should print an error on screen which lead to the root cause of your issue.

Saplog · May 31, 2017, 8:34am

/usr/share/elasticsearch/bin/elasticsearch -p ${PID_DIR}/elasticsearch.pid --quiet -Edefault.path.logs=${LOG_DIR} -Edefault.path.data=${DATA_DIR} -Edefault.path.conf=${CONF_DIR}

Okay i'll try , but what do you put on ${DATA_DIR} ?

/usr/share/elasticsearch/bin/elasticsearch -p 10278/elasticsearch.pid --quiet -Edefault.path.logs=/var/log/elasticsearch/elasticsearch.log -Edefault.path.data=${DATA_DIR} -Edefault.path.conf=/etc/elasticsearch/elasticsearch.yml

Xavy · May 31, 2017, 8:40am

Hello:

Please check /usr/lib/systemd/system/elasticsearch.service; for the variables values.

In my env test, they are:

[Service]
Environment=ES_HOME=/usr/share/elasticsearch
Environment=CONF_DIR=/etc/elasticsearch
Environment=DATA_DIR=/var/lib/elasticsearch
Environment=LOG_DIR=/var/log/elasticsearch
Environment=PID_DIR=/var/run/elasticsearch
EnvironmentFile=-/etc/default/elasticsearch

WorkingDirectory=/usr/share/elasticsearch

User=elasticsearch
Group=elasticsearch

but they could be different on your case (my test scenario is using repo packages for Ubuntu)

Saplog · May 31, 2017, 8:42am

Permission denied, but i'm log with root

Xavy · May 31, 2017, 8:43am

I meant that you opened such a file with a text editor (vi, nano, whatever) to check the variables values on it

Saplog · May 31, 2017, 8:45am

Oh yes sorry ,

[Unit]
Description=Elasticsearch
Documentation=http://www.elastic.co
Wants=network-online.target
After=network-online.target

[Service]
Environment=ES_HOME=/usr/share/elasticsearch
Environment=CONF_DIR=/etc/elasticsearch
Environment=DATA_DIR=/var/lib/elasticsearch
Environment=LOG_DIR=/var/log/elasticsearch
Environment=PID_DIR=/var/run/elasticsearch
EnvironmentFile=-/etc/default/elasticsearch

WorkingDirectory=/usr/share/elasticsearch

User=elasticsearch
Group=elasticsearch

Xavy · May 31, 2017, 8:47am

Then ${DATA_DIR} in your case should be /var/lib/elasticsearch. Please go on substituting each variable by its value as stated on the mentioned file, and then run the command I told you on comment #3

Saplog · May 31, 2017, 8:48am

It's done , and i have now that on /var/log/elasticsearch/elasticsearch.log

Has such a command shown any kind of output, or written to ES log files?

Saplog · May 31, 2017, 8:53am

I dont understand what do you want to see

pts0 · May 31, 2017, 8:57am

log ist telling you the problem :

can not run elasticsearch as root

you should start as "normal" user, not root. Check the user is set in service script. You posted before

user= elasticsearch

Saplog · May 31, 2017, 9:00am

Okay but why it was workings before and now i can start him with roots
So i should add the user in the service script ?

Xavy · May 31, 2017, 9:05am

Hello:

I'm sorry my instructions were not as complete or as clear as it could be desirable.
I'll show a step by step diagnose:

From root: edit /etc/passwd so you assign elasticsearch user a shell (probably it will have /bin/false as shell)
Change to elasticsearch user: su - elasticsearch
Run /usr/share/elasticsearch/bin/elasticsearch -p /var/run/elasticsearch/elastisearch.pid -Edefault.path.logs=/var/log/elasticsearch -Edefault.path.data=/var/lib/elasticsearch -Edefault.path.conf=/etc/elasticsearch

This should bring to your screen something like:
