Clustering | PopChart Server User Guide 4.0.5 |
The first step in configuring your PopChart Server cluster is to enable clustering on all of the servers. There are two ways of placing PopChart Server into a cluster: Auto-cluster and Declared Clusters.
These settings will need to be applied to each server individually.
Auto-clustering is, of course, the most convenient way of enabling clustering. When you auto-cluster, PopChart Server will scan through the entire 255.255.255.0 subnet for other clustering-enabled servers. For example, if PopChart Server's address is 10.0.1.28 and you enable auto-clustering, PopChart Server will cluster with any server whose address is 10.0.1.x (e.g. 10.0.1.1, 10.0.1.2, etc.). In order for this to work, all PopChart Servers must be using the same comm port number.
If PopChart Server is on the same subnet and has the same port and commport settings for all servers, you can enable autoclustering simply by going to the Settings > Clustering page in your Administration Console, checking Enable Clustering, and selecting the Auto Cluster radio button. Each PopChart Server in the cluster will need to be restarted after Applying the changes.
If your servers are on different subnets, or if they do not use the same comm port number, you will be unable to use auto-clustering. However, you can still declare your cluster manually.
For example, suppose you want to cluster instances of PopChart Server running at 134.12.16.32 with a commport of 2002, 168.15.45.24 with a commport of 4008, and 192.63.21.250 with a commport of 7007.
You can enable clustering manually for each server by going to the Settings > Clustering page in the Administration Console, checking Enable Clustering, and selecting the Manual Cluster radio button.
You then need to list the IP addresses and ports for each server in you cluster, separated by a comma, in the Cluster Server List box. For our example setup, you would enter the following: 134.12.16.32:2002, 168.15.45.24:4008, 192.63.21.250:7007.
Not all three addresses would be required. In fact, you may only need to list one address, as once a server finds one server in the cluster, it can find all of the servers in the cluster. For redundancy, however, it is a good idea to list two or three addresses.
