搭建基于MySQL的读写分离工具Amoeba:
Amoeba工具是实现MySQL数据库读写分离的一个工具,前提是基于MySQL主从复制来实现的;

实验环境(虚拟机):
主机 角色
10.10.10.20 多实例加主从复制
10.10.10.30 Amoeba服务器
10.10.10.40 客户端(最后测试使用)

 

1、首先搭建MySQL的主从复制(不在多提);
需要注意的是:在主从库上需要创建一个用户,在主库上创建的用户为amoeba,权限是create,update,insert,delete;
在从库上创建的用户也是amoeba,权限是select;

2、由于Amoeba是基于java的环境去实现的,所以要先安装jdk插件:(先通过windows主机去下载)
http://pan.baidu.com/share/link?shareid=2793927523&uk=1678158691&fid=117337971851932
下载完成后通过xshell自带的ftp软件传到服务器上,然后进行安装:

[root@localhost tools]# tar xf jdk-7u79-linux-x64.tar.gz
[root@localhost tools]# vim /etc/profile      ##编辑jdk需要的环境变量;
export JAVA_HOME=/root/tools/jdk1.7.0_79
export JRE_HOME=/root/tools/jdk1.7.0_79/jre
export PATH=/root/tools/jdk1.7.0_79/bin:$PATH
export CLASSAPTH=./:/root/tools/jdk1.7.0_79/lib:/root/tools/jdk1.7.0_79/lib
[root@localhost tools]# java -version        ##检测jdk是否安装成功,出现如下信息算安装成功;
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

3、下载并安装Amoeba软件:

[root@localhost tools]# mkdir /usr/local/amoeba       ##创建一个目录用来放amoeba的软件;

https://sourceforge.net/projects/amoeba/       ##windows主机登录网址到网页中部的地方下载 Released /OldFiles/amoeba-mysql-0.19.zip,通过xshell自带FTP工具放到服务器上;

[root@localhost amoeba]# cd /usr/local/amoeba/
[root@localhost amoeba]# unzip amoeba-mysql-0.19.zip

[root@localhost amoeba]# ls
LICENSE.txt README.html amoeba-mysql-0.19.zip bin build.xml conf doc lib logs src ##主要用到的目录是conf这个配置目录;

[root@localhost conf]# ls
access_list.conf amoeba.dtd amoeba.xml function.dtd functionMap.xml log4j.dtd log4j.xml rule.dtd rule.xml ruleFunctionMap.xml

[root@localhost conf]# vim amoeba.xml

[root@localhost amoeba]# jobs ##查看后台启动的服务;

4、测试:

[root@localhost~]# mysql -uroot -pxyp123123 -h 10.10.10.30     ##通过客户端去连接amoeba服务器来登录到mysql;

mysql> show databases;      ##查看数据库,已经存在需要配置的库xyp;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
| xyp |
+--------------------+
5 rows in set (0.02 sec)

去从库上停掉slave,方便测试;

mysql> use xyp
Database changed
mysql> create table student(id int(10) not null,name char(20) not null,age int(2) not null);      ##在库里面创建一个表;

mysql> insert into student values(1,‘x‘,23);     ##插入一条信息做测试;

mysql> select * from xyp.student;     ##先去主库上去查,有数据;
+----+------+-----+
| id | name | age |
+----+------+-----+
| 1 | x | 23 |
+----+------+-----+
1 row in set (0.02 sec)

mysql> select * from xyp.student;     ##在amoeba上通过select去查结果没东西,因为从库的状态是停掉的
Empty set (0.01 sec)

mysql> start slave; ##在从库上把状态打开;
Query OK, 0 rows affected (0.00 sec)

mysql> select * from xyp.student;     ##在从amoeba上查看,数据已经被同步过来了;
+----+------+-----+
| id | name | age |
+----+------+-----+
| 1 | x | 23 |
+----+------+-----+
1 row in set (0.02 sec)
