Amoeba for MySQL 測試

參考:http://www.jianzhaoyang.com/database/amoeba_for_mysql
開發者博客:http://amoeba.meidusa.com/wordpress/
基於amoeba實現的MySQL數據庫讀寫分離，負載均衡，可擴展性架構：
amoeba是一個基於j2se開發的數據庫連接池，可對數據庫水平切分，垂直切分，或者兩者結合。

Amoeba for MySQL環境：





軟件環境：
OS:RedHat 5.2 (32bit)
MYSQL:MySQL-5.0.77
Amoeba:amoeba-mysql-1.0.0-BETA
JDK:
jdk-6u14-linux-i586

主要測試功能：
1，
讀寫分離
2，
負載均衡

Amoeba主配置文件：
amoeba.xml
主配置文件，配置所有數據源及Amoeba自身的參數。
rule.xml
配置所有Query路由規則的信息：
functionMap.xml
配置用於解析Query中的函數所對應的Java實現類
nullFunctionMap.xml
配置路由規則中需要使用到的特定函數的實現類。

整體配置方案：
配置MySQL 複製。在amoeba server上安裝JDK
這裏不做詳細說明
配置JAVA環境變量

CODE:

[root@localhost ~]# cat .bashrc
JAVA_HOME=/usr/java/jdk1.6.0_14
CLASSPATH=.{JAVA_HOME}/lib/dt.jar{JAVA_HOME}/lib/tools.jar{JAVA_HOME}/lib{JAVA_HOME}/jre/lib
PATH=$PATH{JAVA_HOME}/bin{JAVA_HOME}/jre/bin
export JAVA_HOME CLASSPATH PATH
amoeba.xml文件配置:
