Hi!,

I am installing cloudstack on centos 6.

I have installed the management server & would like to install DB server separately.
Lets say my infrastructure is as follows.

Management server - 192.168.34.1 (on public network)
Xen cloud Platform (hypervisor) - 192.168.34.2 (on public network)
DB Server - 192.168.34.3 (on internal network)

nfs server - > hast (cluster)
a . node a (freebsd zfs)(internal network)
b. node b (freebsd zfs)(internal network)

In above scenario I am unable to configure the db from management server.

Do I need to install the mysql server on management server too?
if yes- I just installed the mysql server on management server too

I get the access denied error if I start cloud using following cmd
cloud-setup-databases cloud:password@192.168.34.3 --deploy-as=root:password

another thing I am unable to browse the client from manager
if I browse to http://192.168.34.1:8080 it says connection refused.

Please advise.

Thanks in Advance.

My Feedback is that the Cloudstack 3.02 install is very very fragile, and when something goes wrong, the errors are so cryptic and the management logs so verbose that it is a truly maddening experience. I'm currently trying to get through the advanced install, and have just about thrown in the towel, as the logs are just unreadable, and the errors that bubble up back to the management UI are worthless, and make me want to punch myself in the face.

Hi,

I followed the advance guide to get the 1 management server, 1db server , 1 hypervisor & nfs cluster working.
but I failed to install the db configuration on separate DB server.

since the management server dont have mysql.
so if I install the mysql-server on management server & I try to configure the db using management server - it give access denied error.

yesterday late night I configured another management server and configured the DB on the same server.
which is working perfect. so this is not going to work in production at all. :(

if any one using separate db server please let me know.

Thanks,
KeNS

Hmmmm...I have been having a similar experience as Nik Martin sans the desire to punch myself in the face. Although he is expressing himself strongly I do think he is on point with his observations. I had to go through the installation processes multiple times before I got it to work and when it did work it wasn't clear why one installation pass worked and others did not. I also run into circumstances where sometimes I can start an instance and sometimes I cannot.

It is also not clear to me why certain areas of the design are the way they are.

1. Why can't we select customized sizes for our cloud volumes? (or can we?) Why limit us to small(5G), medium(20G) and large (100G) volumes?
2. Why force us to download the iso files even if they are already on a local volume? It would be more convenient to allow us to point to the ISO file that is already on the local disk...and have the o/s do a file copy rather than having to set up a URL/HTTPServer and force a local file through the IP stack. I agree that it' great that we can point out to repository on the web and download the file - but sometimes we're behind firewalls or in a blackbox computing environments with no outside access - so we use local disks.

3. I haven't explored the disaster recovery aspect of Cloudstack yet but there is one statement in the manual that jumps out at me. It says something to the effect that if you need to reinstall Cloudstack Management then you have to reinstall the hypervisors as well because there can be no VMs running when you deploy the management software. In a production environment that could be troubling that a crash of the Management UI s/w or h/w could result in having to reconstruct all your hypervisors and underlying VMs!
(I may have a misunderstanding on that last statement, but if I'm accurate about it then I have a definite concern).

I'm going to revisit CloudStack again soon when I have time, but for the moment I've reverted to using Citrix XenServer with XenCenter. It's much more straightforward and seems less problematic on the install.

While my observations are on the critical side they are intended to be offered respectfully and constructively.
