elasticsearch can't start service in ubuntu 15.10

问题:

I am trying to setup elasticsearch on my system.I installed it but it seems the process is not starting. I cant get response via curl. I read about some problem regarding pid owner not correctly setup, tried the steps but it still isnt working. If i put "set -x" in /etc/init.d/elasticsearch and try

/etc/init.d/elasticsearch restart

I get this output

Been trying whole day and still cant figure this out.
Also "ps -A" shows no elasticsearch process. Please help.

More info:
I tried

sudo -u elasticsearch /usr/share/elasticsearch/bin/elasticsearch -d -p /var/run/elasticsearch.pid --default.config=/etc/elasticsearch/elasticsearch.yml --default.path.home=/usr/share/elasticsearch --default.path.logs=/var/log/elasticsearch --default.path.data=/var/lib/elasticsearch --default.path.work=/tmp/elasticsearch --default.path.conf=/etc/elasticsearch

/
It gives:

      sid@sid-laptop:/etc/init.d$ sudo -u elasticsearch /usr/share/elasticsearch/bin/elasticsearch -d -p /var/run/elasticsearch.pid --default.config=/etc/elasticsearch/elasticsearch.yml --default.path.home=/usr/share/elasticsearch --default.path.logs=/var/log/elasticsearch --default.path.data=/var/lib/elasticsearch --default.path.work=/tmp/elasticsearch --default.path.conf=/etc/elasticsearch     [sudo] password for sid:      sid@sid-laptop:/etc/init.d$ {1.6.2}: pid Failed ...     - FileNotFoundException[/var/run/elasticsearch.pid (Permission denied)]     java.io.FileNotFoundException: /var/run/elasticsearch.pid (Permission denied)         at java.io.FileOutputStream.open0(Native Method)         at java.io.FileOutputStream.open(FileOutputStream.java:270)         at java.io.FileOutputStream.(FileOutputStream.java:213)         at java.io.FileOutputStream.(FileOutputStream.java:162)         at org.elasticsearch.bootstrap.Bootstrap.main(Bootstrap.java:194)         at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:32  

回答1:

Ubuntu don't allow other users than admins to write to /var/run and this happen for good reasons.

Has you can notice elasticsearch is launched by a "elasticsearch" user that elasticsearch creates on install:

sudo -u elasticsearch....

So instead of change /var/run permissions to all users or try to give admin permissions to elasticsearch user i believe the best solution is created a new folder inside /var/run folder

sudo mkdir /var/run/elasticsearch/ 

and give elasticsearch user permissions to it

sudo chown elasticsearch:elasticsearch /var/run/elasticsearch  

After you need to change elasticsearch init script to write the pid file for this new folder

sudo vim /etc/init.d/elasticsearch  

updating the property PID_FILE to

PID_FILE=/var/run/elasticsearch/$NAME.pid 

This has worked for me. I hope it works for you to ;)
