## Introduction

crmsh is a command-line interface for High-Availability cluster
management on GNU/Linux systems, and part of the Clusterlabs
project. It simplifies the configuration, management and
troubleshooting of Pacemaker-based clusters, by providing a powerful
and intuitive set of features.

crmsh can function both as an interactive shell with tab completion
and inline documentation, and as a command-line tool. It can also be
used in batch mode to execute commands from files.

## Documentation

* The website for crmsh is here: [crmsh @ Github.io](http://crmsh.github.io).
* Documentation for the latest stable release is found at the [Github.io documentation](http://crmsh.github.io) page.

## Installation

The GNU Autotools suite is used to configure the OCF root directory,
the Asciidoc tool which is used to generate documentation and the
default daemon user (usually hacluster).

It then calls the python setuptools setup.py to actually process the
Python module sources and install into the Python system site-packages
directory.

```shell
./autogen.sh
./configure
make
make install
```

## Manifest

```shell
./doc: man page, source for the website and other documentation
./crmsh: the code
./templates: configuration templates
./test: unit tests and regression tests
./contrib: vim highlighting scripts and other semi-related
           contributions
./hb_report: log file collection and analysis tool
```

## Development

crmsh is implemented in Python. The source code for crmsh is kept in a
git source repository. To check out the latest development
version, install git and run this command:

```shell
git clone https://github.com/ClusterLabs/crmsh
```

There is a git `pre-commit` hook used to update the data-manifest
which lists all the data files to be installed. To install this, run

```shell
cp contrib/git-hook-pre-commit .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit
```

## Community

* Bugs and issues can be reported at the [crmsh issues @ Github.com](https://github.com/clusterlabs/crmsh/issues) page.
* Any other questions or comments can be made on the [Clusterlabs users mailing list](http://clusterlabs.org/mailman/listinfo/users).
