Installing, Upgrading and Uninstalling a Cluster
Before installing a ListManager cluster or upgrading to a clustered ListManager server, be sure you have software licenses that allows clustering. Contact sales@lyris.com if you have questions about your licenses.
Installing a ListManager Cluster
When installing ListManager, the installer will prompt you as to whether the installation is a new installation, an upgrade or a node. For the first ListManager instance, select New Install. For the second and subsequent installations, select Add Node to Cluster.
The installation will proceed for each node as it does for a single instance of ListManager. You'll need to provide the same database connection information for each node installation as you did for your initial ListManager installation.
Once you have completed installing a node, be sure you configure it.
Upgrading a Cluster
Before upgrading a cluster, please review the important upgrade information for this version.
To upgrade a cluster
1. Shut down all ListManager nodes.
2. Upgrade the primary ListManager node (the first ListManager you installed) first. When prompted by the installer, select "upgrade."
3. Repeat the upgrade for each node.
4. Once the primary node has been upgraded, you may run ListManager on that node while upgrading the subsequent nodes.
Moving a Node
To move a node to different hardware:
1. Shut down the machine the ListManager node is currently running on.
2. Open the file lmcfg.txt (located in C:\Program Files\ListManager or ~/ListManager/bin) using a plain-text editor (such as Notepad or vi).
3. Note the value of $node_name.
4. Install ListManager on the new machine selecting Add Node to Cluster.
5. When asked for a serial code, you may either not provide one or use the one for the previous machine.
6. When the installation is complete, do not start ListManager.
7. Open the file lmcfg.txt (located in C:\Program Files\ListManager or ~/ListManager/bin) using a plain-text editor (such as Notepad or vi).
8. Change the value $node_name to be the same name as the previous node.
9. Start ListManager. The new ListManager node will have the same settings as the previous node. If the IP addresses have changed, you may need to configure the node.
Uninstalling a Node
The process to uninstalla ListManager node is the same as uninstalling a single instance of ListManager. The database will still reference the other node in lyrConfigNodeSettings, but the node will be disabled.
