为了方便选用的mysql为通用二进制：mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz
tar xf mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

chown -R mysql:mysql /mydata/data

确保无误后，可以开始启动mysql服务器了
service mysqld start
如有错误，记得一定得看数据目录下的错误日志，如master.err

于是开始创建复制的账号密码：
master：
grant replication slave on *.* to ‘rep‘@‘192.168.248.%‘ identified by ‘redhat‘;
flush privileges;
注意：主从服务器的防火墙和selinux关闭掉：
service iptables stop
setenforce 0
sed -i ‘s#SELINUX=enforce#SELINUX=permissive#g‘ /etc/selinux/config
开始主从复制步骤：
slave:
mysql>change master to master_host=‘192.168.248.200‘,master_user=‘rep‘,master_password=‘redhat‘,master_auto_position=1;
mysql>start slave;
mysql>show slave status\G

两个yes，说明了主从复制基于GTID已经成功了
于是开始搭建amoeba代理服务器
192.168.248.202：
由于amoeba是基于java开发的于是必须要支持jdk:
jdk-6u45-linux-x64.bin
cd /root
./jdk-6u45-linux-x64.bin
vi /etc/profile.d/java.sh
export JAVA_HOME=/root/jdk1.6.0_45/
export PATH=$PATH:$JAVA_HOME
. /etc/profile.d/java.sh
java -versiom
[root@RS1 ~]# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
安装下载好的amoeba：
amoeba-mysql-3.0.4-BETA-distribution.zip
unzip amoeba-mysql-3.0.4-BETA-distribution.zip /usr/local
mv amoeba-mysql-3.0.4-BETA-distribution/* /usr/local/amoeba

定义完之后，启动amoeba

可以看见java程序进程已经启动了，即amoeba已经启动了
用一个可以登录的mysql客户端登录amoeba服务器:
[root@master ~]# mysql -uroot -p -h192.168.248.202
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

mysql>
断开从服务器的复制：
stop slave;
主从服务器各为amoeba创建一个默认数据库为test的用户，与配置文件一致：
master：
grant all privileges on *.* to ‘amoeba‘@‘192.168.248.%‘ identified by ‘redhat‘;
slave:
grant all privileges on *.* to ‘amoeba‘@‘192.168.248.%‘ identified by ‘redhat‘;
创建完之后再开启复制功能：
start slave；
回到amoeba服务器：
[root@master ~]# mysql -uroot -p -h192.168.248.202
Enter password:

执行读写操作的sql语句，主从服务器各自用tcpdump进行抓包：
master：
[root@master mysql]# tcpdump -i eth0 -s0 -nn -A tcp dst port 3306 and dst host 192.168.248.200
slave：
[root@slave mysql]# tcpdump -i eth0 -s0 -nn -A tcp dst port 3306 and dst host 192.168.248.201
记录：
不知道为啥主从抓包的时候，读写操作的sql语句都在主服务器上可以抓到，而从服务器一直都抓不到
改变了amoeba的配置文件依然还是完全的实现都写操作，这里记录一下结果
基于mysql5.6之GTID新特性的主从模式下的amoeba代理
