ruby command not found

[spuder]

If you use a basic install, you will get an error when you start elasticsearch

root@default-ubuntu-1204:~# service elasticsearch status
/etc/init.d/elasticsearch: line 120: ruby: command not found
elasticsearch  running with PID 14465
root@default-ubuntu-1204:~# curl localhost:9200
curl: (7) couldn't connect to host

The init script should be modified so that ruby isn't a dependency, or the documentation should show an example of how to install ruby. (The first being very preferred in my opinion)

Even if you install ruby and rubygems, you still get issues with the init script because the json gem isn't installed.

Init scripts really shouldn't depend on ruby and specific gems being available system wide.

I agree completely. When we did the big 1.0 rewrite, we put off fixing this particular issue. But Init scripts are on the next release milestone. Check out #321.

[spuder]

Thanks. I'll close this issue infavor of #321

Hi folks -- could you try the 2.0.0_wip branch of this cookbook, and report back any issues in #321? It has the same init scripts now as the packaged version of ES; it's our goal to release a 2.0.0 version that works with ES 2.0.0. It does have some changes from the current version, but depending on how complex your resource usage is, you may or may not be affected. Thanks!
