Corosync: It belongs to the Openais (Open Application Interface Specification) in a project Corosync a version of itself does not have the voting function, after Corosync 2.0 introduced Votequorum subsystem also has the voting function, if we use the 1 version of the , but also need to use the votes to make the decision of how to be good, of course, in Red Hat Cman + Corosync combined with, but early cman and pacemaker can not combine, if want to use

The following commands are implemented using crm and pcs. 1. Install corosync and pacemaker with the rpm package in CentOS6.5.Yum-y install corosync pacemaker2. Configure pacemaker to run as the corosync plug-in:Add the following configuration in/etc/corosync. conf:Secauth: on # enable security authentication for communications between cluster nodesInterface {Bindnetaddr: 192.168.0.0 # specify the network a

First, the concept of pacemaker(1) Pacemaker (pacemaker), is a highly available cluster resource manager. It achieves maximum availability of resource management for node and resource level fault detection and recovery by using the message and member capabilities provided by the preferred cluster infrastructure (Corosync or heartbeat). It monitors and recovers no

0. IntroductionAs a member management layer (membership layer) in Ha scheme, Corosync is responsible for the functions of cluster member management, communication mode (unicast, broadcast, multicast), pacemaker as the CRM layer. In the practice of using Corosync +pacemaker, the problemof brain fissure is encountered. What is brain fissure: in HA cluster, the network communication between nodes through the h

commercial or open-source clusters. Currently Corosync is divided into 1 versions and 2 versions, 1 does not have a voting function, and the 2 version has a voting function.Pacemaker OverviewPacemaker OverviewPacemaker is a cluster resource manager that leverages the message and member capabilities provided by the preferred cluster infrastructure (OpenAIS or heartbeat) for fault detection and recycling by secondary nodes and systems, enabling high availability of clustered services (also known

Linux Corosync + Pacemaker Complete HA structure: Install and configure a high-availability cluster:1. node name: the names of each node in the cluster must be resolved to each other./Etc/hostsIn hosts, the forward and reverse resolution results of the host name must be consistent with those of "uname-n;2.
