mysql amoeba 读写分离

本文在Mysql主从同步的基础上进行配置

不熟悉的盆友请自行乘坐时光机。 Mysql主从同步：http://nothing-whoami.iteye.com/blog/2144294

再加一台主机 amoeba : 192.168.10.21

一、下载amoeba

 

wget http://nchc.dl.sourceforge.net/project/amoeba/Amoeba%20for%20mysql/2.x/amoeba-mysql-binary-2.1.0-RC5.tar.gz

 二、解压并修改amoeba配置文件

			 such as 'multiPool' dbServer

 4 登陆方式

mysql -unothing -p123456 -h192.168.10.21 -P8066

 

这里如果插入的话就会插到 192.168.10.17，读数据的话就会读到 192.168.10.20 。测试时请先停止主从模式。在从机插入数据，再进行试验。

写的简单了点！这是主要的操作过程。至于更详细的！这里推荐两个链接吧
