amoeba 实现读写分离

标签：

中文官网参考地址：http://docs.hexnova.com/amoeba/

下载地址(amoeba-mysql-1.2.0-GA.zip)：http://sourceforge.net/projects/amoeba/files/ 

解压到 C:\wnmp\amoeba 下

dos命令启动amoeba 执行 C:\wnmp\amoeba\bin\amoeba

提示要安装jdk  并设置环境变量 ，设置相关环境变量 

配置amoeba.conf

或者自己写一个ObjectPool。

再次dos启动amoeba  

用用dos   mysql命令登录amoeba实例对象  mysql -uroot -proot -h192.168.80.129 -P8066 

use think_ceshi

就可以读写分离  操作相关数据库了
