几个linux集群节点的辅助管理工具
集群节点监控: Ganglia
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Uses multicast and/or unicast to inject xml data into an rrdtool frontend. Makes it very easy to make custom graphs as it was originally written to handle stats data from HPC clusters http://ganglia.sourceforge.net/
SystemImager
节点统一自动安装部署: SystemImager
SystemImager is software which automates Linux installs, software distribution, and production deployment. SystemImager is a part of System Installation Suite. SystemImager makes it easy to do automated installs (clones), software distribution, content or data distribution, configuration changes, and operating system updates to your network of Linux machines. You can even update from one Linux release version to another! It can also be used to ensure safe production deployments. By saving your current production image before updating to your new production image, you have a highly reliable contingency mechanism. If the new production enviroment is found to be flawed, simply roll-back to the last production image with a simple update command! Some typical environments include: Internet server farms, database server farms, high performance clusters, computer labs, and corporate desktop environments. http://systemimager.org
使用subversion集中管理配置文件版本:ubcon
Subcon allows you to store your essential system configuration files in a subversion repository and easily deploy different configurations to machines in a cluster. It also features optional integration with SystemImager, enabling the deployment of system images and configuration in a single step. A flexible configuration file provides the ability to start, stop, or restart services or run arbitrary scripts when a change in a file or set of files is detected. http://code.google.com/p/subcon/
