Tungsten Cluster supports the creation of composite clusters. This includes multiple active/passive dataservices tied together. One of the dataservices is identified as the active, containing the Primary node and all other dataservices (passive) replicate from it.
Before continuing with deployment you will need the following:
The cluster name for each Active/Passive Cluster and a Composite cluster name to group them.
The list of datasources in each cluster. These are the servers which will be running MySQL.
The list of servers that will run the connector. Each connector will be associated with a preferred cluster but will have access to the Primary regardless of location.
The username and password of the MySQL replication user.
The username and password of the first application user. You may add more users after installation.
All servers must be prepared with the proper prerequisites. See Appendix B, Prerequisites for additional details.
Install the Tungsten Cluster package or download the Tungsten Cluster tarball, and unpack it:
copyshell>cd /opt/continuent/softwareshell>tar zxftungsten-clustering-6.1.25-6.tar.gzChange to the Tungsten Cluster directory:
copyshell>cdtungsten-clustering-6.1.25-6Run tpm to perform the installation. This method assumes you are using the Section 10.3, “tpm Staging Configuration” method:
