amoeba實現mysql讀寫分離

實施環境：

master(amoeba)：192.168.122.201

     安裝：java-1.7.0-openjdk.x86_64，mysql-server，amoeba-mysql-3.0.5-RC-distribution.zip

slave：192.168.122.202

    安裝：mysql-server

配置主從master與slave的主從環境（略過）

master與slave上創建用於amoeba連接數據庫的授權用戶：

grant all privileges on *.* to amoeba@'%' identified by 'amoeba';

amoeba的dbServer.xml配置文件修改：

<dbServer name="abstractServer" abstractive="true">
                  <factoryConfig class="com.meidusa.amoeba.mysql.net.MysqlServerConnectionFactory">
                          <property name="connectionManager">${defaultManager}</property>
                         <property name="sendBufferSize">64</property>
                         <property name="receiveBufferSize">128</property>
                         <!-- mysql port -->
                         <property name="port">3306</property>
                         <!-- mysql schema -->
                         <property name="schema">test</property>
                         <!-- mysql user -->
                         <property name="user">amoeba</property>
                         <property name="password">amoeba</property>
                 </factoryConfig>

   #紅色部分表示amoeba連接主從mysql的端口，操作的庫（這個地方好像只要grant授權足夠，可以忽略這塊），用戶名及密碼（即步驟3創建的用戶名和密碼）

<dbServer name="master"  parent="abstractServer">
                 <factoryConfig>
                         <!-- mysql ip -->
                         <property name="ipAddress">192.168.122.201</property>
                 </factoryConfig>
         </dbServer>
         <dbServer name="slave"  parent="abstractServer">
                 <factoryConfig>
                         <!-- mysql ip -->
                         <property name="ipAddress">192.168.122.202</property>
                 </factoryConfig>
         </dbServer>

  #定義mysql主機

<dbServer name="slavePool" virtual="true">
                 <poolConfig class="com.meidusa.amoeba.server.MultipleServerPool">
                         <!-- Load balancing strategy: 1=ROUNDROBIN , 2=WEIGHTBASED , 3=HA-->
                         <property name="loadbalance">1</property>
                         <!-- Separated by commas,such as: server1,server2,server1 -->
                         <property name="poolNames">slave</property>
                 </poolConfig>
         </dbServer>
 #定義負載均衡策略及主機組

amoeba的amoeba.xml配置文件修改：

<property name="port">8066</property>
<property name="ipAddress">0.0.0.0</property>
#定義amoeba代理服務器端口及綁定ip地址

<property name="user">amoeba</property>
<property name="password">amoeba</property>
#定義amoeba代理服務器的用戶名和密碼

<property name="defaultPool">slavePool</property>
<property name="writePool">master</property>
<property name="readPool">slave</property>

#定義讀寫服務器

創建amoeba日誌存放目錄，並修改權限

mkdir -m a=rwx /usr/local/amoeba/logs

啓動amoeba服務
/usr/local/amoeba/bin/launcher &
