" scheduling algorithm can be used to balance the load well.4. Weighted minimum link (Weighted leastconnections) (WLC)In the case of the server performance difference in the cluster system, the scheduler uses the "Weighted least link" scheduling algorithm to optimize the load balancing performance, and the server with higher weights will bear a large proportion of active connection load. The scheduler can automatically inquire about the load of the re

LVs scheduling Method LVs Scheduling methods: 1.Fixed scheduling method for static adjustment of clothes (1). RR Polling (2). WRR Weighted Polling (3). DH Target Address Hash (4). SH Source Address Hash Method of dynamic adjustment

original address hash: Extract the User IP, according to the hash function to draw a key, and then according to the static mapping table, investigate the corresponding value, that is, target server IP. If the target machine is overloaded, it returns empty. 4, DH target address hash: Ditto, only now extract is the destination address IP to do the hash. Advantages: Both of the above algorithms can achieve the same user access to the same server. 5, LC Minimum connection. Prioritize requests to se

After Ubuntu7.10 was released, it was integrated with compiz-fusion to easily implement 3D effects. Many friends would like to experience it, but it seems that the installation process is not clear and cannot be implemented, now I will write out the configuration process for your reference (ATI graphics card ). 1. After installing the system, set the software source and then update the system. Run the command: sudoapt-getupgrade to run glxgears for more than
