Amoeba separate read and write (the MySQL)

Experimental Operating Environment: centos server three machines

role： 192.168.189.129 master-主

　　　From 192.168.189.130 master-

　　　192.168.189.131 Amoeba

1, the primary structures:

https://www.cnblogs.com/security-guard/

2, on both Amoeba MySQL server to a server authorized users can read and write

Note: The two MySQL servers must be licensed, otherwise it will lead to Amoeba not being given permission to read and write in the mysql

grant all on *.* to 'amoeba'@'%' identified by '123';

flush privileges;

3, is mounted on a third Amoeba Amoeba server

1) install jdk environment

cd / usr / local 

chmod + the X-jdk-6u14-linux- x64.bin 
 . / jdk-6u14-linux- x64.bin 

change jdk installation directory name easy to use 
mv jdk1. 6 .0_14 jdk1. 6

2) configuration environment variable

Configuration environment variable 
vim / etc / profile 
add the following to the end of the file 
Export AMOEBA = / usr / local / Amoeba 
Export JAVA_HOME = / usr / local / jdk1.6 
Export the PATH = $ the PATH: $ JAVA_HOME / bin: $ AMOEBA / bin 

so add new variables into force 
source / etc / profile

3) uploaded to the server installation package Amoeba

4) Create the installation directory for Amoeba

#mkdir /usr/local/amoeba
#tar zxf amoeba-mysql-binary-2.2.0.tar.gz -C /usr/local/amoeba/

5) configuration file dbServers.xml

vim /usr/loca/amoeba/conf/dbServers.xml

6) Edit Amoeba .xml

vim /usr/local/amoeba/conf/amoeba.xml

7) Start Amoeba

/usr/local/amoeba/bin/amoeba start

8) Testing

1, in the open window of a literacy test amoeba Login for separation

#yum -y install mysql

#mysql -ujack-p123 -h192.168.189.131 -P8066

2, create a database wg

create database wg;

use wg;

create table list(id int);

insert into list values(1);
insert into list values(2);

3, stop mysql synchronization from

stop slave;

4、在Amoeba上插入两条数据

insert into list values(3);
insert into list values(4);

5、在Amoeba上查看数据，发现只有1、2没有新数据

6、切换到MySQL主上查看，主上可以查看到所有的新数据

select * from wg.list;

7、在MySQL从上查看数据，这里只有1、2

目前验证完毕，MySQL主有新的数据，说明在数据是王MySQL主上写数据

然后Amoeba查看的数据内容和MySQL从一致，说明数据是往从上读取数据

读写分离配置完毕
