I was able to index 230K documents overnight, doing a curl on health and indices I can see the index and the health returns a yellow status - everything just like on the previous version of ES - except I can't seem to connect to instance. I've tried 3rd party tools - that all work on the last version of ES - and none connect (ElasticHQ for example). When I try to "search" my site returns a blank, white, page - no errors. The installation process seemed very different for this version - as does the start process - and I can't get ES to run as a service with this version. Is it supposed to be installed in a specific location? Right now it's in /opt/elasticsearch-1.6.0 Is it possible to downgrade the installation or copy the index into an installation of a previous version? I just don't want to spend another 8 hours indexing today 😉 Thanks! ---

UPDATE: If I do a "netstat -tanp" on the system running 1.5.2 I get this line, which is not present in 1.6: tcp 0 0 127.0.0.1:55207 127.0.0.1:9200 TIME\_WAIT - 1.5.2 works perfectly. 1.6 is running but nothing can connect to it. Help - please advise 😄 Rob ---

Did you use that exact command or did you replace $IP with your own IP? ---

lol…the exact command…. Okay - I put in 127.0.0.1 and my public facing IP - both didn't return a thing. I hit enter, the cursor drops down a line, and just hangs there. I have to cntr-c to get back to a prompt. ---

Tried it again, as I was responding with my last, and it just timed out: curl: (7) Failed to connect to IP port 9200: connection timed out. But the IP it gives is not anything I've ever seen and isn't anywhere in my netstat ---

How are you installing ES, how are you starting it? Have you checked the logs to see if anything is reported? ---

Mark - sorry - I was in the wrong terminal window when I tried that curl. The return is: curl (7) Failed to connet to IPxxx.xxx.xxx.xxx port 9200: Connection Refused. I installed it per the instructions as follows: curl -L -O [https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.6.0.tar.gz](https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.6.0.tar.gz) tar -xvf elasticsearch-1.6.0.tar.gz cd elasticsearch-1.6.0/bin and started it with this command: ./elasticsearch Also, when it started, the process said "recovered [0] indices…" and then hung, I had to cntr-c out of it, but I posted it as an issue on Github last night and was told that was okay. ---

As I mentioned in the GH issue it's not hung, that is what you see when ES has started and is ready to serve requests. Does `ps -ef|grep java` show Elasticsearch running? ---

That's the first I've seen Tomcat mentioned on this server. I'm running Apache2, php5.9,Mariadb10.x and not much else. No idea how Tomcat got into this mix - like I said, I just followed the instructions as I have with previous versions, on the same image I've been using for months. If I do a ps -aux Tomcat isn't even there. ---

Hmm ok, might just be an environment variable. Why not just use a deb/rpm to install ES, that way you get the service to handle starting of the service? ---

Having not used "Linux" since Unix SCO was all the rage I thought it'd be best to just follow the instructions on the site 😉 Okay - I'm just going to delete this server and create a new one - can you provide me a link to the 1.6 deb package? Thank you for all your help! ---
