Hey why dont you try Datastax Opscenter? Its a cool Gui tool to
start/stop/manage your cluster(even remotely) . It also provides
administrative tools fr checking on the performance with vital statistics.
Definitely worth it.

In your case, since the ccm cluster nodes are bound to localhost
aliases, you would need to set up routing and port forwarding via
iptables from your public IP (10.11.12.13) to the respective localhost
aliases/ports. ccm is great for local testing, but gets to be a pain if
you wish to do some real testing - not because of ccm, but because now
you want to do something that involves actual multi-host networking with
remote access. Even easier, in my opinion; if you really want to begin
testing a real cluster with remote access, which will have a lot more
horsepower than everything on localhost via ccm, then spend $15/month on
3x $5/mo. digitalocean nodes.

Yup. The nodes are not listening to anything but their localhost alias
IP addresses.

`man iptables` ;)

Hey Folks,
I have been using ccm for some time and it's pretty awesome tool to test
out admin stuff. Now, I really want to test modeling data by trying to
access ccm running cassandra using Thrift based pycassaShell client from
remote hosts (not locally). My setup is like this:
Lets say, private IP of this machine is: 10.11.12.13 (Just an example)
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:67392708 errors:0 dropped:0 overruns:0 frame:0
TX packets:67392708 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:7398829042 (6.8 GiB) TX bytes:7398829042 (6.8 GiB)
lo:1 Link encap:Local Loopback
inet addr:127.0.0.2 Mask:255.255.255.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
lo:2 Link encap:Local Loopback
inet addr:127.0.0.3 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
lo:3 Link encap:Local Loopback
inet addr:127.0.0.4 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
and 127.0.0.1 (node1), 127.0.0.2 (node2), 127.0.0.3 (node3), 127.0.0.4
(node4)
$ ccm status
node1: UP
node3: UP
node2: UP
node4: UP
How to connect to any of the instance from non-local hosts? When I do:
pycassaShell --host 10.11.12.13 --port 9160, it throws an exception,
thrift.transport.TTransport.TTransportException: Could not connect to
10.11.12.13:9160
Is there a way to make it work?

Thanks very much. I will try.
The goal of ccm and ccmlib is to make is easy to create, manage and destroy a
small cluster on a local box. It is meant for testing of a Cassandra cluster.

Starting multiple Cassandra nodes on the same machine involves setting loop back aliases and some configuration fiddling.
Lucky for you Sylvain Lebresne made this handy tool in python which does the job for you.
https://github.com/pcmanus/ccm
to run as a service you need a script like this http://www.bajb.net/2012/01/cassandra-service-script/
I haven’t tried this, I just run Cassandra in the foreground of a screen session.
