0 Preface Starting from this article, the author will introduce how to build an ArcGIS 10.1 for server cluster in a Linux environment. Because the cluster involves Server Load balancer processing and requests need to be distributed among different machines, domain name resolution is required. In addition, machines in the cluster need to share the site configurati

This article briefly describes how to configure a Fence_vmware_soap type of stonith device (test-only learning) in Rhel 7 pacemaker.Stonith is the abbreviation for Shoot-the-other-node-in-the-head, and it protects the data from corruption due to node anomalies or simultaneous access.A node unresponsive does not mean that it does not have access to data, and if it wants to be sure that the data is secure, it needs to use Stonith to isolate the node to
