Hi jgan,

It's been a while sind I've worked with this. Looks like fab start is working though. Let me try it out and I'll get back to you in a moment.

[Jeeva-G]

Hi,

Thank you. Do i need to run fab start in all the nodes or its fine with master alone?

Regards, Jeeva.

[alexgustafson]

It should only run on the master alone. This command just starts the master node. On line 101 of the fabfile you will find the stateement: run('bin/disco nodaemon')

This will run disco in the console, disco will echo to the console, if you close the console you disco will exit. If you change the statement to run('bin/disco'). It will start disco as a background daemon process.

[Jeeva-G]

Ok. So, in that case, if i am not wrong, i need to ssh in to slave node and start that as well. Am i right? And, how does both communicate, do i need to configure it in the browser?

[alexgustafson]

If the disco nodes ( Master and Slave ) are properly configured, then the Master will ssh to the slaves it knows about and start them all. In the browser you can configure the slave nodes, the corresponding entries must also be in the etc/hosts files. ( see https://github.com/alexgustafson/disco_vagrant/tree/master/templates )

If you run all the fab steps in order, fabric should take care of the configuration for you. ( I'm not 100% sure if everything is working at the moment though, or if some manual tweaking is still necessary somewhere )

[Jeeva-G]

Ok. Yeah i checked that hosts file and it is present. And yes, my slaves were running in slave machine disconode1 which is also running. And i updated fab file to bin/disco.
