This article mainly introduces "what are the variables of OCF". In the daily operation, I believe that many people have doubts about the variables of OCF. The editor consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the variables of OCF?" Next, please follow the editor to study!

6 script variabl

6.1$ OCF_ROOT

The root of the hierarchy of the OCF resource broker. Cannot be changed through a resource agent. Usually / usr/lib/ocf

6. 2 $OCF_FUNCTIONS_DIR

This is the directory where the resource agent shell library is located, and where .ocf _ shellfuncs is located. It is usually defined with $OCF_ROOT, and the resource agent should not be changed. However, when testing a resource agent, this variable may be overloaded through the command line.

6.3USD OCF_RESOURCE_INSTANCE

Resource instance name. For basic resources (non-clone, non-state resources), the variable is the resource name. For clones and stateful resources, this variable is a base name and a colon, followed by a clone instance serial number.

6.40 $_ _ OCF_ACTION

The currently invoked operation. This is the first command line argument that the cluster manager uses when invoking the resource agent.

6.50 $_ _ OCF_SCRIPT_NAME

The name of the resource agent. This is the name of the resource agent and does not contain the previous directory name.

6.6 $HA_RSCTMP

The temporary directory used by the resource agent. The system boot sequence ensures that the directory is empty at system startup (as is the case with any LSB-compatible linux distribution), and after a node starts, the directory does not contain any data.

At this point, the study of "what are the variables of OCF" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
