【Amoeba】-实验-读写分离测试、负载均衡测试

1、环境：

10.96.47.195:3306	用于写
10.96.47.195:3307	用于读，暂时关闭从服务
10.96.47.195:8066	是amoeba代理服务的端口

 

在3306和3307中分别授权用于amoeba连接的用户信息

[root@HaiwaiTest_VM_195 conf]# mysql -S /home/mysql_3306/mysql.sock

 GRANT USAGE ON *.* TO 'test_proxy'@'10.25.47.195' IDENTIFIED BY  'test_proxy' ;

 GRANT ALL PRIVILEGES ON `zstest`.* TO 'test_proxy'@'10.25.47.195';

 

[root@HaiwaiTest_VM_195 conf]# mysql -S /home/mysql_3307/mysql.sock

 GRANT USAGE ON *.* TO 'test_proxy'@'10.25.47.195' IDENTIFIED BY  'test_proxy' ;

 GRANT ALL PRIVILEGES ON `zstest`.* TO 'test_proxy'@'10.25.47.195';

 

 

2、配置amoeba

[root@HaiwaiTest_VM_195 ~]# cd /usr/local/amoeba-mysql/conf

[root@HaiwaiTest_VM_195 conf]# vim amoeba.xml   修改以下内容

<property name="port">8066</property>

amoeba服务的默认启动端口,可以修改为其他端口

 

<property name="user">amoeba_test</property>	可以随便写，用于登陆代理使用的mysql -h -uamoeba_test -p123456 -P8066 使用的
<property name="password">123456</property>	可以随便写，登陆密码

 

<property name="defaultPool">server1</property>
<property name="writePool">server1</property>	用于写的服务器，server1需要在dbServers.xml中配置，稍后会有详细配置内容说明
<property name="readPool">server2</property>	用于读的服务器，server2需要在dbServers.xml中配置，稍后会有详细配置内容说明

            

[root@HaiwaiTest_VM_195 conf]# vim dbServers.xml   修改以下内容

 

                        <!-- mysql port -->

<property name="port">3306</property>

？ 是用来配置写的默认端口的吗

 

                        <!-- mysql schema -->

<property name="schema">zstest</property>

amoeba连接连接的库名，这个需要提前在库中有此授权记录

 

                        <!-- mysql user -->

<property name="user">test_proxy</property>	amoeba连接数据库的用户名，这个需要提前在库中有此授权记录
<property name="password">test_proxy</property>	amoeba连接数据库的密码，这个需要提前在库中有此授权记录

 

 

        <dbServer name="server1"  parent="abstractServer">

                <factoryConfig>

                        <!-- mysql ip -->

<property name="ipAddress">10.25.47.195</property>	配置server1的连接信息，此项为连接的IP
<property name="port">3306</property>	配置server1的连接信息，此项为连接的IP的端口号，因为server1要实现写的功能，所有为3306端口

                </factoryConfig>

        </dbServer>

 

        <dbServer name="server2"  parent="abstractServer">

                <factoryConfig>

                        <!-- mysql ip -->

<property name="ipAddress">10.25.47.195</property>	配置server2的连接信息，此项为连接的IP
<property name="port">3307</property>	配置server2的连接信息，此项为连接的IP的端口号，因为server2要实现读的功能，所有为3307端口

                </factoryConfig>

        </dbServer>

 

<dbServer name="multiPool" virtual="true">

实现读功能缓冲池，可以实现负载均衡

                <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">server2,server1,server2</property>

                </poolConfig>

        </dbServer>

 

 

3、启动

[root@HaiwaiTest_VM_195 conf]# amoeba start

检查是否启动成功

[root@HaiwaiTest_VM_195 conf]# netstat -tulnp | grep java

tcp        0      0 :::8066                     :::*                        LISTEN      13068/java         

tcp        0      0 ::ffff:127.0.0.1:27624      :::*              LISTEN      13068/java 

 

4、测试读写分离功能
