Amoeba新版本MYSQL读写分离配置
2011-07-26 11:46

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，因为新版的Amoeba2.10对5.1以下版本不稳定。
结构图
Step 1:配置Amoeba192.168.2.8读写分离
1：解压安装包
[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/
2：进入配置目录，浏览文件
[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：进入主配置文件目录
[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
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
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>
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
需要手动增加SERVER2代码如下：
<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>
最终改变成如下：
<?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,

add attribute with name virtual = "true" in dbServer, but the configuration does not allow the element with name factoryConfig

-->
<dbServer name="abstractServer" abstractive="true">

</poolConfig>
</dbServer>
</amoeba:dbServers>
6：修改log4j.xml 取消日志文件生成（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 &
