amoeba讀寫分離實驗配置

實驗環境

mysql slave : 127.0.0.1  port: 3306
mysql master : 47.104.27.47 port: 3306
amoeba proxy : 127.0.0.1 port:8066

                        If you need to configure multiple dbServer with load balancing that can be simplified by the following configuration:
                         add attribute with name virtual = "true" in dbServer, but the configuration does not allow the element with name factoryConfig
                         such as 'multiPool' dbServer
