Hi Community

I want to configure Couchdb HA on my 3 node cluster so if one of the nodes fails the other 2 still supporting the system. CouchDB team told me that it is a built-in feature starting CouchDB  V2, which is unfortunate as Kazoo is using CouchDB V1.1.1 and I cant find any article how to upgrade Kazoo-BigCouch to higher versions so I can support HA. Currently if I turned off one of the 3 nodes, the system collapse and start throwing errors.

How have you overcame this issue using Kazoo V4.3?

 

There is only way to upgrade bigcouch to CouchDB 2.3.1. Firstly you should create a new cluster of CouchDB 2.3.1 then replicate all data from Bigcouch to new CouchDB cluster with using some utility from Kazoo repository. As far as I remember its  clonedb. You can use even curl for this.

Hello everyone,

I have cluster kazoo server in which rabbitmq is running on public server.Question is how to hide rabbitmq port so nobody can access from Ui

For correct reply you gave too little information about network topology and what  do you actually want. But I can suggest you to make it work on local interface only or use firewall.
