mysql基于amoeba配置读写分离

                     Mysql高级集群-读写分离Amoeba
                     
   mysql在配置好主从复制之后,已经达到双机热备和容灾的效果。此博客是建立在主从复制的前提上
,mysql基于amoeba的配置读写分离在我看来:就是为了达到数据库高可用性,安全性以及高并发,达到
负载均衡的效果。说简单点,我个人觉得意思就是让主服务器轻松点,不易挂掉。还有就是充分利用从服务器。 

本人水平有限,望各位大神多多指点指点。我非常乐意听取意见。
此版本建立在rhel6.4 x86_64 以及mysql 5.1.50 上,‘#’为需要修改的地方!

Master-->Slave
                                                                    
一、环境介绍
Master-IP:10.0.0.201
Slave- IP:10.0.0.202
Amobea-IP:10.0.0.203

二、安装JDK
# mkdir /amoeba
# tar -xvf jdk-7u40-linux-x64.tar.gz -C /amoeba/
# vim /etc/profile
JAVA_HOME=/amoeba/jdk1.7.0_40
export JAVA_HOME

PATH=$JAVA_HOME/bin:$PATH
export PATH

CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH
export CLASSPATH

# java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)

三、安装Amoeba
# unzip amoeba-mysql-1.3.1-BETA.zip -d /usr/local/amoeba/
# chmod -R +x /usr/local/amoeba/bin/


四、主从授权
>grant all privileges on *.* to ‘amoeba‘@‘%‘ identified by ‘amoeba123‘;
>flush privileges;


五、配置Amoeba文件
# cd /usr/local/amoeba/conf

六、修改Amoeba启动脚本
# vim /usr/local/amoeba/bin/amoeba
#DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss128k" 将此行注释掉,增加一下行
DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss256k"  增加这一行

七、启动Amoeba脚本
# nohup bash -x amoeba &
# cat nohup.out 日志是否成功?
# ps -ef | grep amoeba   查看进程是否启动成功
