Amoeba新版本如何与MYSQL读写分离配置

官方简介
Amoeba的中文意思是变型虫
主要解决：
• 降低 数据切分带来的复杂多数据库结构
• 提供切分规则并降低 数据切分规则 给应用带来的影响
• 降低db 与客户端的连接数
• 读写分离

个人简单描述
可能你还没明白Amoebla这鬼东西主要干麻的呢！比方说PHP环境众所周知，PHP没有数据连接池，如果PHP环境下MYSQL访问量大时会蹦掉，除非配置Cluster集群，而Amoeba就是在PHP程序和MYSQL之间，充当一个缓冲的作用。

准备工作
  • Server:192.168.1.208 #Amoeba
  • Server:192.168.1.11  #NDBD1（主）
  • Server:1921.68.1.13  #NDBD2（从）
  • 注：11和13两台服务器上，事先请安装好MYSQL单向步，不会配置访问http://skyson.blog.51cto.com/2497647/556600
  • 另请安装MYSQL版本必须5.1以上，可以参考pdf，因为新版的Amoeba2.10对5.1以下版本不稳定。



Step 1:配置Amoeba192.168.2.8读写分离  
  1. 1：解压安装包
  2. [root@Management down]# mkdir /usr/local/amoeba
    [root@Management down]# tar -zxf amoeba-mysql-binary-2.1.0-RC5.tar.gz -C /usr/local/amoeba/
  1. 2：进入配置目录，浏览文件
  2. [root@Management down]# cd /usr/local/amoeba/
    [root@Management amoeba]# ll
    total 88
    drwxr-xr-x 2 root root    4096 Jul 26 11:57 benchmark
    drwxr-xr-x 2 root root    4096 Feb 28 09:25 bin
    -rw-r--r-- 1 root root    3983 May 18 13:43 changelogs.txt
    drwxr-xr-x 2 root root    4096 Jul 26 11:57 conf
    drwxr-xr-x 3 root root    4096 Jul 26 11:57 lib
    -rw-r--r-- 1 root root 34520 May 18 13:43 LICENSE.txt
    -rw-r--r-- 1 root root    2031 May 18 13:43 README.html
  3. 3：进入主配置文件目录
  4. [root@Management amoeba]# cd conf/
    [root@Management conf]# ls
    access_list.conf    amoeba.xml        dbServers.xml    functionMap.xml    log4j.xml    ruleFunctionMap.xml
    amoeba.dtd                dbserver.dtd    function.dtd     log4j.dtd                rule.dtd     rule.xml
  1. 在这里我主要介绍配置  amoeba.xml、    dbServers.xml、 log4j.xml 三个主要的配置文件，其它文件没有特殊需要默认就可以了夺
  2. 4：vi amoeba.xml 修改主配置文件
  • 4.1）把默认端口8066改成3306
  • <property name="port">3066</property>
  • 4.2）把默认连接用户名和密码改成自己的
  • <property name="user">sky</property>

                                                                                    <property name="password">123456</property>
  • 4.3）把默认的客户端线程数，请求数及服务端回应数改成200，300，300
  • <property name="readThreadPoolSize">200</property>

                                                    <!-- proxy server client process thread size -->
                                                    <property name="clientSideThreadPoolSize">300</property>

                                                    <!-- mysql server data packet process thread size -->
                                                    <property name="serverSideThreadPoolSize">300</property
  • 4.4）把默认注释掉的读写分离选项，把注释去掉并readpool修改成server2
  • <!--
                                    -->
                                    <property name="writePool">server1</property>
                                    <property name="readPool">server2</property>

                                         
  1.  5：vi dbServers.xml 增加SEVER2模块，里面的连接用户名密码及地址都表示两台MYSQL的物理机器，192.168.1.11和192.168.1.13 另SERVER1是写，SERVER是读
  3. 需要手动增加SERVER2代码如下：
  4.   <dbServer name="abstractServer" abstractive="true">

        <factoryConfig class="com.meidusa.amoeba.mysql.net.MysqlServerConnectionFactory">

          <property name="manager">${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">root</property>

            

          <!--    mysql password

              -->

          <property name="password">123456</property>

        </factoryConfig>



        <poolConfig class="com.meidusa.amoeba.net.poolable.PoolableObjectPool">

          <property name="maxActive">500</property>

          <property name="maxIdle">500</property>

          <property name="minIdle">10</property>

          <property name="minEvictableIdleTimeMillis">600000</property>

          <property name="timeBetweenEvictionRunsMillis">600000</property>

          <property name="testOnBorrow">true</property>

          <property name="testWhileIdle">true</property>

        </poolConfig>

      </dbServer>



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

        <factoryConfig>

          <!-- mysql ip -->

          <property name="ipAddress">192.168.2.11</property>

        </factoryConfig>

      </dbServer>


  1. 最终改变成如下：
  1. <?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

  • 6：修改log4j.xml 取消日志文件生成，如做pdf时（太大了，磁盘很容易满）
  • <param name="file" value="${amoeba.home}/logs/project.log"/>
    改成
    <param name="file" value="<![CDATA[${amoeba.home}/logs/project.log>/dev/null]]>"/>
  • 7：性能优化，打开bin/amoeba

  • DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss128k"
    改成
    DEFAULT_OPTS="-server -Xms512m -Xmx512m -Xmn100m -Xss1204k"
  • 8：启动amoeba
  • nohup /usr/local/amoeba/bin/amoeba start 2>&1 >/dev/null &
