Starting Conga

Once luci is installed (an Enterprise Linux 5 package), its database must be initialized and an admin account must be setup. These tasks are accomplished with the luci_admin command line utility. After this, the luci service should be started:

service luci start
Starting luci:　　　　　　　　　　　　　　　　　　　　　　 [　OK　]
Please, point your web browser to https://myhostname:8084 to access luci

And that’s all there is to it. Let’s log into luci and look around. The administrative login window looks like this:

Once you’ve logged in, you are at the “homebase” tab of the administrative web interface. From this tab, you can add clusters, storage systems, and users. The other tabs support administrative tasks specific to either clusters or storage systems.

Let’s walk through using Conga to perform some basic tasks. Most likely, you’ll start using Conga by administering an existing cluster. This is where we’ll start.

Conga and clusters: Accessing an existing cluster

To illustrate this task, we’ll start with an existing cluster. Note that we’ll need all the nodes of the cluster to be up and running when we start as luci will not let us attempt to manage part of an existing cluster, or a cluster with nodes that are unreachable.
