| Linux Virtual Server management system based on Linux Virtual Server and Keepalived, provide enterprises with a stable, maintainable, scalable, high availability load balancing management solutions. In this paper the main research contents include the management of the virtual server cluster, monitoring of running status of the virtual server cluster, the virtual server cluster operation data statistics, the heat load of the Keepalived configuration file. For traditional load balancing based on Linux virtual server and Keepalived need to manually configure each Linux virtual server, and if the configuration changes, also need to configure each Linux virtual server again. The scalability of this method is very low. And the traditional load balancing server cluster can’t monitor the state of the load balancing server cluster, also can’t get a global load balancing statistics of the cluster.Linux virtual server management system provides a centralized configuration management system for load balancing server cluster which is based on the Linux virtual server and Keepalived. Set up the Linux virtual server as a cluster, then configure the cluster of the Linux virtual server remotely and batch. But also the system provides for a backup configuration file processing for error operations. Management system provides monitoring and alarm for server in the cluster, which can monitoring status of the cluster effectively. Management system also provides a uniform procedures for collection of cluster load. Collect load statistics of each server in the cluster in real time, which makes get cluster load statistics easier. Linux virtual server management system also provides a heat loading for configuration file of Keepalived, which changes the method that need to restart Keepalived to make the system load configuration file. This make Keepalived can load configuration dynamically when it has been running, which improve the performance of the system greatly. |
