The error is not logstash specific. It is a java error. have [a read here](https://confluence.atlassian.com/bitbucketserverkb/forking-jvm-error-12-cannot-allocate-memory-or-error-12-not-enough-space-779171744.html) it might help. ---

Hi Achmad, There are no tricks in IT 🙂 The error clearly says what the problem is. You dont have java installed on the machine your trying to install logstash. I am not sure how and what and why but mabey a clear guide can help. Please have a read [here](https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-ubuntu-14-04) and I think this will push you in the right direction.. Paul. ---
