Description

A kind of method and apparatus of server cluster automatic deployment
Technical field
The present invention relates to software system architecture field, particularly relate to a kind of method and apparatus of server cluster automatic deployment.
Background technology
Cloud computing technology through development for many years day by day ripe, virtual, cloud network and Yunan County's congruence technology at development, and perfect these extended familys of cloud computing.IT (Information technology) service huge economic benefit and the social benefit such as use, IT resources effective utilization, green energy conservation as required that cloud computing brings to society, the government of the developed countries such as the U.S., European Union, Japan is not only made to be listed in national development strategy, even Asia, Africa and Latin America etc. the developing countries also paid much attention to, the multinational national data centers such as such as Bangladesh, Laos, Zambia, Mali build as spring bamboo after the rain.Technical conditions and the environment of cloud computing large-scale application possess, and the construction of cloud data center has become the not coilable trend of industry.
But current cloud data center technology still also exists very large development space, current cloud data center technology is also in the problem solving emphatically individual data central interior.But along with the deep development of globalization, increasing conglomerate has cross-region to set up the needs of branch, and the data center of each region, each level also arises at the historic moment, and each department of each ministries and commissions, governments at all levels also all sets up the data center of oneself.These numerous data centers are still in funnel-shaped Construction and management state---do things in his own way between each data center.It is embodied in following some:
Overall construction cost is high.Because data center's level is many, website quantity is many, in data center, software application is coupled with physical computing and memory device and binds, higher construction cost end to end must be brought, simultaneously the machine room of L1 layer power, freeze, civil engineering, security protection cost of investment to compare the proportion of the IT infrastructure cost of investment of L2 layer larger, thus reduce the investment return specific efficiency (ROI) of building at conceptual data center.
Complex management, operation cost is high.Because the type of service of each hierarchical data center carrying is different, software and hardware system operation management demand and disaster-tolerant backup guarantee strategies also different, be unfavorable for system Easy pulling apparatus and the coordinated management of each layer data center infrastructures resource, reduce and draw logical each layer data center to realize the maintenance efficiency of global administration; Simultaneously due to physical resource and application close coupling, the deployment of business is reached the standard grade, and the life cycle management such as dilatation and upgrading operation all can be pulled one hair and move the whole body, and causes data center's management maintenance operation complicated.
The current application of cloud computing IaaS (namely infrastructure serve) platform widely, especially constantly expands the demand of large-scale cluster.On a large amount of clustered node, how fast and effeciently to carry out the installation upgrading of batch operation system and application software, and automation can dispose the challenge that the group system comprising cloud computing and cloud memory node is puzzlement system manager always further.
If only only solve the installation question of operating system, existing technology generally adopts network installation to realize extensive large batch of operation, usually has two kinds of modes.
One adopts PXE (Pre-Boot eXecution Environment) mode to guide: make node to be installed download reflection by the automatic distally management node of network, and support the start-up course of local node thus.In start-up course, management node meeting distributing IP (Internet protocol) address, use TFTP (TFTP) to serve download one again to start in software kit to local memory and to perform, start software kit by this and complete the setting of terminal basic software, thus guide the terminal operating system be pre-installed in server.
Another kind is NFS (NFS) shared network mounting means: using the node of in network as nfs server, and mapping document of operation system is stored in nfs server, node to be installed is downloaded image file by network startup in the mode backing up/copy and is completed installation.
First kind of way layoutprocedure is loaded down with trivial details, and the second way needs artificial startup node host to be installed and run corresponding program just to carry out data receiver, is unfavorable for the bookkeeping of extensive environment.In addition, dispose cloud computing cluster environment except basic operating system installation, also need to do other configuration efforts many, comprise stored configuration, virtual network and software merit rating etc.These operations all need to communicate between management node and calculating/memory node continually.But in the face of thousands of even more large-scale cluster environment, need some purview certifications just can set up data transmission link between each node, it is also unpractical for being manually configured at every station server.
Summary of the invention
