1、安装jdk
root@proxy:~# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
2、配置dbServer.xml
root@proxy:/usr/local/amoeba/conf# cat dbServers.xml
<?xml version="1.0" encoding="gbk"?>
<!--
Each dbServer needs to be configured into a Pool,
If you need to configure multiple dbServer with load balancing that can be simplified by the following configuration:
add attribute with name virtual = "true" in dbServer, but the configuration does not allow the element with name factoryConfig
such as 'multiPool' dbServer
-->
<dbServer name="abstractServer" abstractive="true">
<factoryConfig class="com.meidusa.amoeba.mysql.net.MysqlServerConnectionFactory">
<property name="manager">${defaultManager}</property>
<property name="sendBufferSize">64</property>

</dbServer>
<dbServer name="master1" parent="abstractServer">

<dbServer name="slave2" parent="abstractServer">
<factoryConfig>
<!-- mysql ip -->
<property name="ipAddress">10.10.10.42</property>

rp池配置的是salve1和slave2节点
<dbServer name="rp" virtual="true">
<poolConfig class="com.meidusa.amoeba.server.MultipleServerPool">

</poolConfig>
</dbServer>
wp池配置的是master1和master2节点
<dbServer name="wp" virtual="true">
<poolConfig class="com.meidusa.amoeba.server.MultipleServerPool">
<!-- Load balancing strategy: 1=ROUNDROBIN , 2=WEIGHTBASED , 3=HA-->

<!-- Separated by commas,such as: server1,server2,server1 -->
<property name="poolNames">master1,master2</property>
</poolConfig>
</dbServer>
3、配置amoeba.xml
root@proxy:/usr/local/amoeba/conf# cat amoeba.xml

4、启动amoeba
root@proxy:/usr/local/amoeba# bin/amoeba start &
[1] 2511
root@proxy:/usr/local/amoeba#
The stack size specified is too small, Specify at least 160k
Could not create the Java virtual machine.
[1]+ Exit 1 bin/amoeba start
更改bin/amoeba文件
DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss128k"
更改为
DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss256k"
启动正常之后,连接amoeba
root@proxy:~# mysql -uroot -p -h10.10.10.39 -P8066
Enter password:

连接报错,查看root.log的输出

查看数据库连接权限
root@localhost:mysql MySQL-> select host,user from user; | |

5、测试读写分离
停止master2,slave1,slave2节点的复制
root@localhost:(none) MySQL-> stop slave;
Query OK, 0 rows affected (0.04 sec)
root@localhost:(none) MySQL-> show slave status G
1. row **

Relay_Log_Pos: 607
Relay_Master_Log_File: master1-bin.000007
Slave_IO_Running: No

使用amoeba连接,往测试表t1中插入测试数据

master1查看表t1
root@localhost:mysql MySQL-> select * from test.t1; | |
---|---|

1 row in set (0.00 sec)
在master2,slave1,slave2上查看表t1
root@localhost:(none) MySQL-> use test;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
root@localhost:test MySQL-> select * from t1;
Empty set (0.00 sec)
在proxy上查看表t1表的数据
root@10.10.10.39:test MySQL-> select * from t1;
Empty set (0.05 sec)
在proxy上无法查看插入的数据,说明读是在rp池里,而rp池只有slave1和slave2,数据没有同步到从节点。
