The Design And Implementation Of High Reliable Cluster’s Deployment

With the development of web technology,the application fo web has been morediversiform and complicated. The concept of usrer orietned makes new web sites havenew characteristics,namely High concurrency, high flow rate, large amount of data, thecomplicated logic,which also raised new requirement on website construction.so bothlarge portal application or enterprise appilication，especially for the key business system,are meeting new challenges.Therefore,we did some research aiming at improvingreliability,scalability,performance of the the key business systetm.The Web deployment scheme Based Windows focus on how to provide users withservices which are fast, high reliable, high scalable. In order to meet the increasinglystringent requirements of users, in the practice part, combined with the specific projectrequirements, we puts forward a complete set of web application deployment solution,which meets the performance index requirements.The deployment scheme is logicallydivided into three layers to meet the functional requirements and non-functionalrequirements.It consist of web layer, business layer and data layer. The windows NLBserver load balance cluster is introdued in web layer to solve the problem of entrancesingle point failure.In this layer we also use Nginx to implement the access control. Thefunction of business layer is to forward user’s request according to user web deploymentang user request path by realising the cluster of Apache and Tomcat.Meanwhile Weimprove the cas single sign on system so that the users can login conveniently And datalayer introduces the Database failover cluster of sql database server to implements thereliability and bachup of database.We use the tool ab to test the performance of the system.Through strict experimentsand tests, the deployment scheme reaches the expected purpose. The overall systemoperats efficiency and stable.
