一、由于是MySql集群，所以就不可能只有一个MySql，需要多个MySql，具体安装步骤，可以参考http://www.cnblogs.com/ywzq/p/4882140.html这个地址进行安装配置和启动。
二、现在MySql有了，开始安装Ameoba
1.下载文件：amoeba-mysql-0.32.tar.gz
2.创建文件amoeba
mkdir amoeba
cd amoeba
3.解压文件（由于amoeba的作者打包时没太注意，所以你要先件个文件）
tar amoeba-mysql-0.32.tar.gz
cd conf/
配置前端访问接口<server></server>如：
<server>
<property name="port">8066</property>
<property name="ipAddress">101.201.140.214</property>
<property name="readThreadPoolSize">500</property>
<property name="clientSideThreadPoolSize">500</property>
<property name="serverSideThreadPoolSize">500</property>
<property name="netBufferSize">200</property>
<property name="tcpNoDelay">true</property>

<property name="testOnBorrow">true</property>
<property name="testWhileIdle">true</property>
</poolConfig>
</dbServer>
配置Slave（从>1）
<dbServer name="slave2">
<factoryConfig class="com.meidusa.amoeba.mysql.net.MysqlServerConnectionFactory">
<property name="manager">defaultManager</property>
<property name="port">4307</property>
<property name="ipAddress">101.201.140.214</property>
<property name="schema">test</property>
<property name="user">root</property>
<property name="password">root4307</property>

<property name="timeBetweenEvictionRunsMillis">600000</property>
<property name="testOnBorrow">true</property>
<property name="testWhileIdle">true</property>
</poolConfig>
</dbServer>
配置写入MySql
<dbServer name="virtualSlave" virtual="true">
<poolConfig class="com.meidusa.amoeba.server.MultipleServerPool">
<!-- 1=ROUNDROBIN , 2=WEIGHTBASED -->
<property name="loadbalance">1</property>
<property name="poolNames">slave1,slave2</property>
</poolConfig>
</dbServer>
分配读写使用的数据库
<queryRouter class="com.meidusa.amoeba.mysql.parser.MysqlQueryRouter">
<property name="ruleConfig">${amoeba.home}/conf/rule.xml</property>
<property name="functionConfig">${amoeba.home}/conf/functionMap.xml</property>
<property name="ruleFunctionConfig">${amoeba.home}/conf/ruleFunctionMap.xml</property>
<property name="LRUMapSize">1500</property>
<property name="defaultPool">master</property>
<property name="writePool">master</property>

<tableRule name="slave2" schema="test" defaultPools="slave1"/>
<tableRule name="master" schema="t" defaultPools="master"/>
</amoeba:rule>
三.主从复制
1、修改MySql配置文件my.cnf
mast（主库）配置文件：
server-id = 4308
log-bin = mysql-bin
log-bin-index = mysql-bin.index
binlog-do-db= ng_base
binlog-do-db= ng_push
binlog-ignore-db = test
binlog-ignore-db = mysql
binlog-ignore-db = information_schema
slave（从库1）配置文件：
server-id = 4307
log-bin = mysql-bin
log-bin-index = mysql-bin.index
relay-log = slave-relay-bin
relay-log-index = slave-relay-bin.index
sync_master_info = 1
sync_relay_log = 1
sync_relay_log_info = 1
二、配置主从复制
1、主库操作
授权给从数据库服务器192.168.10.131
mysql> GRANT REPLICATION slave ON *.* to 'rep1'@'192.168.10.131' identified by ‘root4308’;
查询主数据库状态
Mysql> show master status;
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000005 | 261 | | |
-- SLAVE STOP;
2、 从库操作
change master to
master_host='101.201.140.214',
master_user='slave',
master_password='root4308',
master_log_file='binlog.000005',
master_log_pos=107;
正确执行后启动Slave同步进程
SLAVE START;
可以使用show slave status\G检查
