Operation thinking: Through the DRBD to achieve data synchronization, through the Corosync+pacemaker (hereinafter referred to as CP) to detect failures and transfer, only one of the normal state of work, the other only to detect and synchronize data, when there is a failure, Server2 automatically take over all business, and synchronizing the data to another (of course, it doesn't have to sync successfully at this point ...). This is illustrated below:

The RHCs cluster suite, such as Redhat, is based on the Corosync implementation.Corosync only provides

Corosync Introduction: Corosync can use a simple configuration file to define the way and protocol of information delivery when passing information. It is an emerging software, launched in 2008, but in fact it is not a real sense of the new software, in 2002, there is a project Openais, it is too large, split into two subprojects, which can achieve HA heartbeat information transmission function is Corosync, its code 60% Left or right from Openais. Corosync can provide a complete ha function, bu

Corosync is used to enable multiple machines to communicate with each other (maintaining heartbeats), while pacemaker manages the entire cluster's operations on the Corosync top. Corosync is the future direction of development. In later new projects, the general use of Corosync, and Hb_gui can provide a good ha management functions, can achieve graphical management. In addition, related graphics have RHCs suite Luci+ricci. Consistency of highly avail
