First, the concept of heartbeat Linux-ha's full name is High-availability Linux, an Open-source project, the goal of which is to provide an enhanced Linux reliability (reliability), through the joint efforts of Community developers The availability (availability) and serviceability (serviceability) (RAS) cluster solution. Heartbeat is a component of the Linux-ha project and the most successful example of t

Today, when the listener is configured, an error has been encountered: Javax.naming.NameNotFoundException:Name Com.xxx.xxx.xxxListener is isn't bound in the context, 4 hours later, I finally figured out why. Because of the use of spring injection, it is used in the listener class that you define @ResourcePrivate Iusermanage usermanage; annotation, but spring's injection is after filter and

High Availability is divided into three layers: 1. Implementation of the underlying information layer:HeartbeatCorosyncCman2. Resource Management, implementation method:Heartbeat-V1: haresourceHeartbeat-V2: crmHeartbeat-V3: pacemakerRHCS: rgmanagerNote: Resource Manager pacemaker can be used in combination with all underlying communication implementation methods.3. Resource proxy layer, implementation method:Heartbeat-v1LSBOCFSTONITH To achieve high availability, You need to configure the follow

CRM: Cluster Resources ManagerProvides a basic platform for calling non-ha-ware applicationsGenerally, a high-availability service includes multiple resources. Multiple resources belonging to the same service must run on one node, by default, it is flat (after completing this experiment, I believe you will have some knowledge about the mechanism of Cluster Resource Nodes) Configuration process: (here I will continue to use the environment in the previous section)# Ssh node2 'service

System centos6.0 Objective: The httpd service of two machines provides the same service and uses heartbeat to implement hot backup of httpd. to manage resources in a unified manner, the configuration must be written to both services, provides the nfs service for convenient management. 650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131228/013G33223-0.jpg "title =" Photo 1.jpg "/> Lv1: 192.168.182.130 Lv2: 192.168.182.129 Vip: 192.1

The heartbeat timeout refers to an online client (TCP connection) that has not received any messages from the client for a specified period of time, and that the client is considered to be out of line.Why do you need a heartbeat mechanism? Because the server does not immediately feel (some may take a long time to feel) for some client drops (possibly because of a network disconnection, or a client program e

How do you know if the HA cluster is working properly, and simulate environment testing is a good way to test the following five steps before putting the heartbeat high-availability cluster into the production environment to determine if HA is working properly. First, normal shutdown and restart of the master node heartbeat First on the main node node1 the "service he
