mysql5.6版本基于GTID双主-docker方式-新环境没有数据

#(0)环境规划

mysql版本:5.6
master01 :  192.168.19.131
master02 : 192.168.19.132

#(1)安装docker和docker-compose

curl -o /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce-17.06.0.ce-1.el7.centos.x86_64 -y
systemctl enable docker
systemctl  start docker
cat > /etc/docker/daemon.json <<EOF
{
     "registry-mirrors": ["https://ui5lsypg.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

sudo curl -L https://mirrors.aliyun.com/docker-toolbox/linux/compose/1.21.2/docker-compose-Linux-x86_64 > /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version

#（2）准备目录

mkdir /mysql3307/{data,conf} -pv
mkdir /temp/docker/compose/ -pv 

#（3）master01 和 master02 的配置文件
注意修改server-id和 auto_increment_offset

#（4）compose文件

#cat /temp/docker/mysql3307/mysql3307.yaml
version: ‘2.2‘
services:
    mysql3307:
        hostname: mysql3307
        container_name: mysql3307
        restart: always
        image: registry.cn-hangzhou.aliyuncs.com/wangfang-dev/mysql:5.6
        ports:
            - 3307:3306
        volumes:
            - /mysql3307/conf:/etc/mysql/conf.d
            - /mysql3307/data:/var/lib/mysql
        environment:
            MYSQL_ROOT_PASSWORD: 123456
        cpus: 1
        mem_limit: 2048m

#（5）启动容器

docker-compose -f /temp/docker/mysql3307/mysql3307.yaml up -d

两台容器正常启动成功

#（6）在master01上配置复制权限

    docker exec -it mysql3307 bash
    mysql -uroot -p123456
    grant replication slave,replication client on *.* to ‘rep‘@‘%‘ identified by ‘rep‘;

#（7）在master02发起连接以及验证

    docker exec -it mysql3307 bash
    mysql -uroot -p123456
    change master to master_host=‘192.168.19.131‘,master_user=‘rep‘,master_password=‘rep‘,master_port=3307,master_auto_position=1;
    start slave;
    show slave status\G

#（8）在master01上发起连接以及验证

docker exec -it mysql3307 bash
mysql -uroot -p123456
change master to master_host=‘192.168.19.132‘,master_user=‘rep‘,master_password=‘rep‘,master_port=3307,master_auto_position=1;
start slave;

#（9）分别在master01和master02 进行dml, dcl语句验证
master01上

master02上

master01上

master02上

master01上
