We have centOS based system where openbd is setup with jetty version 8.1
My requirement is now to upgrade the version of 8 to latest 9.x.x version.
I do not find the exact example to do this.
Please help me to basic steps to do OR kindly share some experience how I can achieve it.
Thanks.

I am trying to upgrade a Couchbase Community server that is currently running 3.0 to 4.0. I am using the 'Amazon Linux' on AWS, and have used the CentOS 6 build to upgrade from 2.5 to 3.0 - that upgrade was super smooth. According to the documentation, I should be able to go from 3.x to 4.x just fine as well.
http://developer.couchbase.com/documentation/server/4.0/install/upgrade-matrix.html:
Upgrade from the latest version 3.x directly to version 4.x using any supported upgrade strategy.
But I get the message
couchbase-server conflicts with couchbase-server-community-4.0.0-4051.x86_64
I have found that the couchbase-server name is now reserved for the enterprise edition, and couchbase-server-community is now used in 4.0 for the community edition, which would explain the conflict. https://issues.couchbase.com/browse/MB-15716
Is this really an upgrade-breaking change? I cannot find any documentation on how to resolve this change short of uninstalling and reinstalling.
If it were me and since you are on AWS, just spin up new instances, install Couchbase on them and do rebalances where you add one in and remove an old one (1 in, 1 out or 2 in, 2 out, etc.). With the same amount going in and out of the cluster, the cluster will do a swap rebalance which is the most efficient. All of this can be done while up and serving traffic. This is a very standard upgrade path and the recommended approach when in the cloud.
Once upgraded, discard the old instances. Yes you are running more instances at the same time during the upgrade, but for the cost of a few lattes you are upgraded smoothly.
I have experienced the same conflict when trying to upgrade from Community version 3.0.1 to Community 4.0.0.
It is worth mentioning that if you uninstall the 3.0.1 version and then install 4.0.0, all your buckets and their data are kept. Maybe there are some cases where this would fail, always good to take a backup first, but in my case the transformation was smooth.
This was on my developer machine, for a cloud installation I really like the swap in/out which means you can do the upgrade without interruption of the service.
Is there any RethinkDB chef solo cookbook that allows one to install latest rethinkdb on ubuntu 14.04 / AWS.
I tried couple options, however it didn't help.
https://github.com/vFense/rethinkdb-chef - how to install latest version?
https://github.com/sprij/rethinkdb-cookbook.git - source compilation takes hours
I would appreciate any help regarding this.
Thanks
Try the cookbook that is available from the community repository first:
https://supermarket.chef.io/cookbooks/rethinkdb
It claims to be integration tested on Ubuntu. If it doesn't work under chef-solo, then I'd advise you to switch to local mode chef client instead.
https://www.chef.io/blog/2013/10/31/chef-client-z-from-zero-to-chef-in-8-5-seconds/
PS
Also checkout Berkshelf for managing cookbook dependencies. It's a standard tool in the chefdk
I updated rethinkdb-chef to work with the latest version of RethinkDB as well as removed the network portion of the .kitchen.yml file. I validated that this does work on CentOS 6 and Ubuntu 14.04.
I still need to write tests as well as documentation. As per Marks answer, try to use the community supported version 1st. I created this cookbook, so that I can customize it as per my needs with vFense.
I have to monitor traffic on my system. CentOS 7 is installated on system. For that I have found mrtg tool that gives a visual display of traffic also. I have search a lot but could not found guide for CentOS 7 version.
Can anyone guide me its all steps briefly ?
For CentOS 7, you can follow guide here. Although it is for older version but I also works on CentOS 7. I could not include all steps here. It is simple just follow the urls.
I want to try changing my development environment from Windows 8 to Ubuntu so I would like to know if it is possible to install CF11 Trial on an Ubuntu? It will be my first time working with Linux. I already know how to install Postgre 9.3 and pgAdmin. I'm clueless with CF though. Can anyone help me?
Ubuntu 13.04 and 13.10 are supported with ColdFusion 11. Here is the list of supported environments. You can download CF11 here. For installation instructions, see: Installing the Server Configuration
Looks like after migration to Eclipse, the lowest version of Jetty available is 7.
Does anybody know any link which I could use to download Jetty 6 distribution?
http://archive.eclipse.org/jetty/index.html doesn't have it.
you can still download jetty-6 from the archived Codehaus website:
http://web.archive.org/web/20150506133523/http://dist.codehaus.org/jetty/
(really though, we have released Jetty 9.x now...look into updating, if you need help with that ping us on the dev lists)
