response time allocation of a weight, the longer the corresponding time, the smaller the weight, the less likely to be selected. A background thread periodically reads the evaluation response time from the status and computes a weight for each server. The calculation of weight is also relatively simple responsetime minus each server's own average responsetime is the weight of the server. Use Roubine policy to select server when the Statas is not formed when it is first run.6, Retryrule (accordi

Set up Let's pause for a moment and take a look at the symbols and conventions used in this article, as well as some considerations for setting up the environment. Commands executed as root on the system are prefixed with root@host#. Use the user@host# sudo as root on the system to prefix with the sudo execution command. A co
