Amoeba配置

标签：

1. 配置环境：

启动服务：特别注意：所有节点一定要关闭Iptables

2. 安装Mysql（192.168.1.99）

# yum install mysql
# yum install mysql-server
# yum install mysql-devel
# chgrp -R mysql /var/lib/mysql
# chmod -R 770 /var/lib/mysql

# service mysqld start 
# mysql
 >SET PASSWORD FOR ‘root‘@‘localhost‘ = PASSWORD(‘secret_password‘);

>flush privileges;

# chkconfig --levels 345 mysqld on

自定义解决登录问题：

# mysql –uroot –p

# grant all privileges on *.* to root@192.168.1.101 identified by ‘good’;

# flush privileges;

到192.168.1.101下客户端连接到mysql

 删除所有mysql库下user表所有记录

# mysql –uroot –p

>insert into mysql.user(host,user,password) values ("localhost","root",p
assword("good"));

>grant all privileges on *.* to root@127.0.0.1 identified by ‘good’;

>flush privileges;

>grant all privileges on *.* to root@localhost identified by ‘good’;

>flush privileges;

>quit

#mysql –uroot –pgood –h127.0.0.1 –P3306

3. 安装Java1.6.0（192.168.1.99）

当需要开发Java 相关的程序时候就会需要下载JDK 建立Java 需要的环境。

使用yum 的安装方式

#yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel

安装完成后检查Java 版本是不是正确

#java -version

出现版本的信息

java version "1.6.0_20"

OpenJDK Runtime Environment (IcedTea6 1.9.8) (rhel-1.22.1.9.8.el5_6-x86_64)

OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

设定环境变量

#vi /etc/profile

将以下的设定复制到文件中

JAVA_HOME=/usr/lib/jvm/java-1.6.0 依当时安装路径设定

PATH=$PATH:$JAVA_HOME/bin

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

export PATH JAVA_HOME CLASSPATH

启用新的配置文件

#source /etc/profile

或者:直接复制amoeba目录下的profile到/etc即可

4. 安装Amoeba2.0.1（192.168.1.99）

# cd /usr/local

# mkdir amoeba

# tar –zxvf amoeba-mysql-binary-2.0.1-BETA.tar.gz –C /usr/local/amoeba

# vi /usr/local/amoeba/conf/dbServer.xml

5. 配置Amoeba（192.168.1.99）

注意：配置文件中红色部分（源码实例注释密码验证，需取消注释）

5.1 配置conf/dbServers.xml （对真实Mysql数据连接的配置）

<?xml version="1.0" encoding="gbk"?>

<!DOCTYPE amoeba:dbServers SYSTEM "dbserver.dtd">

<amoeba:dbServers xmlns:amoeba="http://amoeba.meidusa.com/">

  <!--

   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="poolNames">server1</property>

  </poolConfig>

 </dbServer>

</amoeba:dbServers>

5.2、配置conf/amoeba.xml

<?xml version="1.0" encoding="gbk"?>

<!DOCTYPE amoeba:configuration SYSTEM "amoeba.dtd">

6. 配置分片数据（192.168.1.99）

6.1 配置conf/dbServers.xml （添加如下代码）

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

  <factoryConfig>

   <!-- mysql ip -->

   <property name="ipAddress">192.168.0.1</property>

  </factoryConfig>

 </dbServer>

6.2 配置conf/rule.xml （全部替换如下代码）

<?xml version="1.0" encoding="gbk"?>

<!DOCTYPE amoeba:rule SYSTEM "rule.dtd">

<amoeba:rule xmlns:amoeba="http://amoeba.meidusa.com/">

  <tableRule name="staff" schema="test" defaultPools="server1,server2">

            <rule name="rule1" ruleResult="POOLNAME">

                   <parameters>ID</parameters>

                   <expression><![CDATA[

                 var division = ID % 2;

                 case division when 0 then ‘server1‘;

                               when 1 then ‘server2‘;

                 end case;

                    ]]></expression>

            </rule>

   </tableRule>

</amoeba:rule>
