linux - Elasticsearch can't write to log files

Question

I would like to activate logs of elasticsearch .

When I run elasticsearch binaries, I realize that I have problems with logging : the configuration cannot be loaded !

Here is the output :

~ $ sudo /usr/share/elasticsearch/bin/elasticsearch
Failed to configure logging...

Java HotSpot(TM) Server VM warning: You have loaded library /usr/share/elasticsearch/lib/sigar/libsigar-x86-linux.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

I am running under linuxmint 17 and using latest ES.

Answer 1

If you installed elasticsearch using a package manager like yum or apt-get you should not start elasticsearch this way. Try to use the service: for instance /etc/init.d/elasticsearch or using the command sudo service elasticsearch start

You should also check if the logging.yml file is at the location mentioned in the stack trace:/usr/share/elasticsearch/config

Using sudo to start elasticsearch is not good, you could do sudo elasticsearch to run as the elasticsearch user, but I prefer to use the service call as described in the second sentence.

Hope that helps
