CPG_OVERVIEW(8) Corosync Cluster Engine Programmer's Manual CPG_OVERVIEW(8)
NAME
cpg_overview - CPG library overview
OVERVIEW
The CPG library is delivered with the corosync project. This library
is used to create distributed applications that operate properly
during cluster partitions, merges, and faults.
The library provides a mechanism to:
* handle abstraction for multiple instances of a CPG library in one
application
* join one or more groups
* leave one or more groups
* Deliver messages to members of that group
* Deliver configuration changes
* Iterate members of groups
SECURITY
If encryption is enabled in corosync.conf, the CPG library will
encrypt and authenticate message contents. Applications must run as
the ais user to be validated by corosync on IPC connection, otherwise
they will be unable to access the corosync services.
